98-422: A flight is a small military unit within the larger structure of an air force , naval air service, or army air corps; and is usually subordinate to a larger squadron . A military aircraft flight is typically composed of four aircraft, though two to six aircraft may also form an aircraft flight; along with their aircrews and ground staff. In some very specific examples, typically involving historic aircraft,

196-527: A squadron . Numbered flights are uncommon, and are usually only found in basic training facilities. An alphabetic flight is an operational component of a flying or ground squadron, not an independent unit; alphabetic flights within a squadron normally have identical or similar functions, and are normally designated A, B, C, and so, on within the squadron. Flights in the USAF are generally authorised to have between 20 and 100 personnel, and are normally commanded by

294-600: A "flak rocket" concept, which led Walter Dornberger to ask Wernher von Braun to prepare a study on a guided missile able to reach between 15,000 and 18,000 m (49,000 and 59,000 ft) altitude. Von Braun became convinced a better solution was a manned rocket interceptor, and said as much to the director of the T-Amt , Roluf Lucht , in July. The directors of the Luftwaffe flak arm were not interested in manned aircraft, and

392-594: A "hit" is essentially a fixed percentage per round. In order to attack a target, guns fire continually while the aircraft are in range in order to launch as many shells as possible, increasing the chance that one of these will end up within the lethal range. Against the Boeing B-17 , which operated just within the range of the numerous German eighty-eights , an average of 2,805 rounds had to be fired per bomber destroyed. Bombers flying at higher altitudes require larger guns and shells to reach them. This greatly increases

490-739: A 300 to 600 pounds (140 to 270 kg) warhead for a 30 to 60 percent kill probability. This weapon did not emerge for 16 years, when it entered operation as the RIM-8 Talos . Heavy shipping losses to kamikaze attacks during the Liberation of the Philippines and the Battle of Okinawa provided additional incentive for guided missile development. This led to the British Fairey Stooge and Brakemine efforts, and

588-413: A Combined Joint Task Force (CJTF) would be such a temporary grouping that includes elements of more than one armed service and more than one nation. Surface-to-air missile The first attempt at SAM development took place during World War II , but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during

686-530: A German Staffel , Italian gruppo or Polish eskadra (10 aircraft in 1939). This was in contrast to air squadrons of the British Commonwealth or United States , which usually had 12–18 aircraft, divided into two to four flights. Until 1949, between one and four French escadrilles formed a groupe . Since then, however, escadrilles have been subordinate to escadrons . As such, groupes and escadrons are

784-532: A SAM system in earnest with the opening of the Cold War . Joseph Stalin was worried that Moscow would be subjected to American and British air raids , like those against Berlin , and, in 1951, he demanded that a missile system to counter a 900 bomber raid be built as quickly as possible. This led to the S-25 Berkut system ( NATO reporting name : SA-1 "Guild"), which was designed, developed and deployed in

882-500: A balanced, combined combat force. The formations only differ in their ability to achieve different scales of application of force to achieve different strategic, operational and tactical goals and mission objectives." It is a composite military organization that includes a mixture of integrated and operationally attached sub-units, and is usually combat-capable. Examples of formations include divisions , brigades , battalions , wings , etc. Formation may also refer to tactical formation ,

980-592: A command is a collection of units and formations under the control of a single officer, although during World War II a command was also a name given to a battlegroup in the United States Army . In general, it is an administrative and executive strategic headquarters that is responsible to the national government or the national military headquarters . It is not uncommon for a nation's services to each consist of their own command (such as Land Component, Air Component, Naval Component, and Medical Component in

1078-460: A company-grade officer ( lieutenant or captain ), and/or a flight chief, usually a senior non-commissioned officer with the rank of master sergeant or senior master sergeant . In USAF flying squadrons, the term flight also designates a tactical sub-unit of a squadron consisting of two or three elements (designated "sections" in U.S. Army and U.S. Naval Aviation ), with each element consisting of two or three aircraft. The flight operates under

1176-407: A conventional war. Once a major group unto itself, medium-range designs have seen less development since the 1990s, as the focus has changed to unconventional warfare. Developments have also been made in onboard maneuverability. Israel's David's Sling Stunner missile is designed to intercept the newest generation of tactical ballistic missiles at low altitude. The multi-stage interceptor consists of

1274-692: A degree, leading to the introduction of the FIM-43 Redeye , SA-7 Grail and Blowpipe . Rapid improvement in the 1980s led to second generation designs, like the FIM-92 Stinger , 9K34 Strela-3 (SA-14), Igla-1 and Starstreak , with dramatically improved performance. By the 1990s to the 2010s, the Chinese had developed designs drawing influence from these, notably the FN-6 and the QW series . Through

1372-416: A drawing was presented, was by inventor Gustav Rasmus in 1931, who proposed a design that would home in on the sound of an aircraft's engines. During World War II , efforts were started to develop surface-to-air missiles as it was generally considered that flak was of little use against bombers of ever-increasing performance. The lethal radius of a flak shell is fairly small, and the chance of delivering

1470-570: A flight may contain as many as twelve aircraft, as is the case with the Battle of Britain Memorial Flight (BBMF) of the British Royal Air Force (RAF). In most usages, two or more flights make up a squadron . Foreign languages equivalents include escadrille ( French ), escuadrilla ( Spanish ), esquadrilha ( Portuguese ), patrulă ( Romanian ), zveno ( Russian ), and Schwarm ( German ). In

1568-550: A flight may further be sub-divided into two sections, each containing two to three aircraft, which share ground staff with the other section, and are usually commanded by a flight lieutenant. The Royal Navy's (RN) Fleet Air Arm (FAA), the Army Air Corps (AAC), and other Commonwealth naval and army aviation arms also have flights. In the Fleet Air Arm, a flight could be as few as a single helicopter operating from

1666-424: A fraction of personnel in infantry units. In western militaries, a joint force is defined as a unit or formation comprising representation of combat power from two or more branches of the military. Gendarmeries , military police and security forces , including equivalents such as paramilitary forces , militia , internal troops and police tactical unit , are an internal security service common in most of

1764-467: A head-on approach at low speeds comparable to manned aircraft. These designs included the Feuerlilie, Schmetterling and Enzian. The second group were high-speed missiles, typically supersonic, that flew directly towards their targets from below. These included Wasserfall and Rheintochter. Both types used radio control for guidance, either by eye, or by comparing the returns of the missile and target on

1862-610: A long time, and were devised by various military thinkers throughout European history. For example, the modern Corps was first introduced in France about 1805 by Napoleon as a more flexible tactical grouping of two or more divisions during the Napoleonic Wars . OF 8: Lieutenant General OR-2: private first class Rungs may be skipped in this ladder: for example, typically NATO forces skip from battalion to brigade. Likewise, only large military powers may have organizations at

1960-468: A loosely defined group of aircraft capable of similar tasks, in most cases not more than six aeroplanes in each. During the war, the escadrille became the basic independent unit of aviation within the French armed forces. An escadrille was a homogeneous unit, armed with a single type of aeroplane, with permanent flying and ground personnel attached, motorised transport and tent hangars . By mid-1915,

2058-485: A member of the government's cabinet , usually known as a minister of defence . In presidential systems , such as the United States , the president is the commander-in-chief , and the cabinet-level defense minister is second in command. Subordinated to that position are often secretaries for specific major operational divisions of the armed forces as a whole, such as those that provide general support services to

2156-482: A part of military or paramilitary organizations, such as insurgent forces, often emulate military organizations, or use these structures. The use of formalized ranks in a hierarchical structure came into widespread use with the Roman Army . In modern times, executive control, management and administration of military organization is typically undertaken by governments through a government department within

2254-439: A part of their multi-layered air defence. SAM systems generally fall into two broad groups based on their guidance systems, those using radar and those using some other means. Longer range missiles generally use radar for early detection and guidance. Early SAM systems generally used tracking radars and fed guidance information to the missile using radio control concepts, referred to in the field as command guidance . Through

2352-492: A rush program. Early units entered operational service on 7 May 1955, and the entire system ringing Moscow was completely activated by June 1956. The system failed, however, to detect, track, and intercept the only overflight of the Soviet capital Moscow by a U-2 reconnaissance plane on July 5, 1956. The S-25 was a static system, but efforts were also put into a smaller design that would be much more mobile. This emerged in 1957 as

2450-462: A separate tracking radar for attack. Short range systems are more likely to be entirely visual for detection. Hybrid systems are also common. The MIM-72 Chaparral was fired optically, but normally operated with a short range early warning radar that displayed targets to the operator. This radar, the FAAR , was taken into the field with a Gama Goat and set up behind the lines. Information was passed to

2548-522: A single radar screen. Development of all these systems was carried out at the same time, and the war ended before any of them was ready for combat use. The infighting between various groups in the military also delayed development. Some extreme fighter designs, like the Komet and Natter , also overlapped with SAMs in their intended uses. Albert Speer was especially supportive of missile development. In his opinion, had they been consistently developed from

2646-702: A smaller ship. A ground flight within an air force is roughly equivalent to a platoon in an army, and may be commanded by a flight lieutenant, flying officer , pilot officer , or warrant officer . These ground flights may carry out operational roles (such as air traffic control , airfield defence , or firefighting ), engineering roles (such as aircraft maintenance , ground-based mechanical engineering , or other ground systems maintenance), support roles (including medical , dental, physical training , supply and logistics , training and education, and legal units), or purely administrative roles (such as finance , infrastructure, or human resource management). A flight

2744-584: A solid-fuel, rocket motor booster, followed by an asymmetrical kill vehicle with advanced steering for super-maneuverability during the kill-stage. A three-pulse motor provides additional acceleration and maneuverability during the terminal phase. MANPAD systems first developed in the 1960s and proved themselves in battle during the 1970s. MANPADS normally have ranges on the order of 3 km (1.9 mi) and are effective against attack helicopters and aircraft making ground attacks. Against fixed wing aircraft, they can be very effective, forcing them to fly outside

2842-491: A squadron of tanks augmented with infantry, or the combination of a full company of infantry with a full squadron of tanks. During World War II the Red Army used the same basic organizational structure. However, in the beginning many units were greatly underpowered and their size was actually one level below on the ladder that is usually used elsewhere; for example, a division in the early-WWII Red Army would have been about

2940-703: A temporary grouping for a specific operational purpose. Aside from administrative hierarchical forms of organization that have evolved since the early 17th century in Europe, fighting forces have been grouped for specific operational purposes into mission-related organizations such as the German Kampfgruppe or the U.S. Combat Team (Army) and Task Force (Navy) during the Second World War, or the Soviet Operational manoeuvre group during

3038-432: A total of 45 ICBM missile flights. Under U.S. military and FAA common usage, for air traffic control and separation purposes, a "flight" of aircraft is simply two or more aircraft intentionally operating in close proximity to each other (typically in formation) under a designated "flight leader", without regard to military organisational hierarchy. An escadrille (literal translations: "squad" or "small squadron")

3136-519: A variation of the SARH technique, but based on laser illumination instead of radar. These have the advantage of being small and very fast acting, as well as highly accurate. A few older designs use purely optical tracking and command guidance, perhaps the best known example of this is the British Rapier system, which was initially an all-optical system with high accuracy. All SAM systems from

In larger armed forces, the cultures between the different branches of the armed forces can be quite different. Most smaller countries have a single organization that encompasses all armed forces employed by the country in question. Armies of developing countries tend to consist primarily of infantry , while developed countries armies tend to have larger units manning expensive equipment and only

3332-416: Is also a basic unit of guided missiles, such as surface-to-air missiles (SAMs). The United States Air Force (USAF) has three types of flights: numbered, alphabetic, and aircraft (which may be designated by alpha-numerics or name). A numbered flight is a unit with a unique base, wing , group , or Numbered Air Force mission; such as training or finance, though not large enough to warrant designation as

3430-593: Is considered its sub-unit or minor unit. It is not uncommon in the United States for unit and formation to be used synonymously. In Commonwealth practice, formation is not used for smaller organizations such as battalions, which are instead called "units", and their constituent platoons or companies are referred to as sub-units. In the Commonwealth, formations are divisions, brigades, etc. Different armed forces , and even different branches of service of

3528-450: Is divided into sections (platoons) composed of 3 x "groupes de combat" of 7 soldiers, plus a group of vehicle crews and a HQ that includes 2 x snipers. Army , army group , region , and theatre are all large formations that vary significantly between armed forces in size and hierarchy position. While divisions were the traditional level at which support elements (field artillery, hospital, logistics and maintenance, etc.) were added to

3626-567: Is due to improved rocket fuels and ever-smaller electronics in the guidance systems. Some very long-range systems remain, notably the Russian S-400 , which has a range of 400 km (250 mi). Medium-range designs, like the Rapier and 2K12 Kub , are specifically designed to be highly mobile with very fast, or zero, setup times. Many of these designs were mounted on armoured vehicles, allowing them to keep pace with mobile operations in

3724-619: Is expected that they would be more widely used against sea skimming missiles rather than aircraft . Virtually all surface warships can be armed with SAMs, and naval SAMs are a necessity for all front-line surface warships. Some warship types specialize in anti-air warfare e.g. Ticonderoga -class cruisers equipped with the Aegis combat system or Kirov -class cruisers with the S-300F Fort missile system. Modern Warships may carry all three types (from long-range to short-range) of SAMs as

3822-450: Is primarily based on a number of standard groupings of vessels, including the carrier strike group and the expeditionary strike group . Additionally, naval organization continues aboard a single ship. The complement forms three or four departments (such as tactical and engineering), each of which has a number of divisions, followed by work centers. The organizational structures of air forces vary between nations: some air forces (such as

4018-475: Is the label given to flights in the air forces and navies of some French-speaking countries. While the term is frequently translated into English as "squadron", an escadrille was originally a smaller unit (whereas the French escadron , also translated as "squadron", in the context of aviation is a much larger unit, comparable in status to a naval squadron). The first air escadrilles were formed in France before World War I , in 1912. They were initially

4116-439: Is the structuring of the armed forces of a state so as to offer such military capability as a national defense policy may require. Formal military organization tends to use hierarchical forms (see Modern hierarchy for terminology and approximate troop strength per hierarchical unit). In some countries, paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not

4214-549: The Armée de l'air had grown to 119 escadrilles of 10 aircraft each: 14 of fighters, 50 of bombers and the rest reconnaissance, spotter and communications units. While escadrilles initially operated independently, during the Battle of Verdun (1916), chasseur (fighter) escadrilles were formed into larger formations, for easier coordination. During World War II , French escadrilles usually fielded between 10 and 12 aircraft. Hence they were roughly equivalent to

A formation is defined by the U.S. Department of Defense as "two or more aircraft, ships, or units proceeding together under a commander".

The U.S. Army Air Forces had also considered collision-course weapons (like the German radio-controlled concepts) and launched Project Thumper in 1946. This was merged with another project, Wizard, and emerged as the CIM-10 Bomarc in 1959. The Bomarc had a range of over 500 km, but it was quite expensive and somewhat unreliable. Development of Oerlikon 's RSD 58 started in 1947, and

4508-545: The Royal New Zealand Navy , or those navies that are effectively coast guards , are commanded by a rear-admiral (two-star rank), commodore (one-star rank) or even a captain . Aircraft carriers are typically commanded by a captain. Submarines and destroyers are typically commanded by a captain or commander. Some destroyers, particularly smaller destroyers such as frigates (formerly known as destroyer escorts ) are usually commanded by officers with

4606-527: The Sea Slug . The Vietnam War was the first modern war in which guided antiaircraft missiles seriously challenged highly advanced supersonic jet aircraft. It would also be the first and only time that the latest and most modern air defense technologies of the Soviet Union and the most modern jet fighter planes and bombers of the United States confronted each other in combat (if one does not count

The end of the war led to the British efforts being used strictly for research and development throughout their lifetime. In the immediate post-war era, SAM developments were under way around the world, with several of these entering service in the early- and mid-1950s. Coming to

The modern Royal Canadian Air Force uses Air division as the formation between wings and the entire air command. Like the RAF, Canadian wings consist of squadrons. A task force is a unit or formation created as

4900-614: The armed forces are divided into three military branches (also service, armed service, or military service ): army , navy , and air force . Many countries have a variation on the standard model of three basic military branches. Some nations also organize their cyber force , emergencies service, medical service , military logistics , space force , marines , and special forces such as commandos or airborne forces as independent armed services. A nation's border guard or coast guard may also be an independent branch of its military, although in many nations border guard or coast guard

4998-469: The flotilla level and higher is less commonly abided by, as ships operate in smaller or larger groups in various situations that may change at a moment's notice. However, there is some common terminology used throughout navies to communicate the general concept of how many vessels might be in a unit. Navies are generally organized into groups for a specific purpose, usually strategic, and these organizational groupings appear and disappear frequently based on

5096-489: The 1960s, the semi-active radar homing (SARH) concept became much more common. In SARH, the reflections of the tracking radar's broadcasts are picked up by a receiver in the missile, which homes in on this signal. SARH has the advantage of leaving most of the equipment on the ground, while also eliminating the need for the ground station to communicate with the missile after launch. Smaller missiles, especially MANPADS, generally use infrared homing guidance systems. These have

5194-581: The Cold War. In the British and Commonwealth armies the battlegroup became the usual grouping of companies during the Second World War and the Cold War. Within NATO, a Joint Task Force (JTF) would be such a temporary grouping that includes elements from more than one armed service, a Combined Task Force (CTF) would be such a temporary grouping that includes elements from more than one nation, and

5292-463: The U.S. Army Force Management Support Agency that prescribes the organization, manning, and equipage of units from divisional size and down, but also including the headquarters of Corps and Armies. It also provides information on the mission and capabilities of a unit as well as the unit's current status. A general TOE is applicable to a type of unit (for instance, infantry) rather than a specific unit (the 3rd Infantry Division). In this way, all units of

Early efforts to directly attack the missiles sites as part of Operation Spring High and Operation Iron Hand were generally unsuccessful, but the introduction of Wild Weasel aircraft carrying Shrike missiles and the Standard ARM missile changed the situation dramatically. Feint and counterfeint followed as each side introduced new tactics to try to gain

5488-532: The advantage of being "fire-and-forget", once launched they will home on the target on their own with no external signals needed. In comparison, SARH systems require the tracking radar to illuminate the target, which may require them to be exposed through the attack. Systems combining an infrared seeker as a terminal guidance system on a missile using SARH are also known, like the MIM-46 Mauler , but these are generally rare. Some newer short-range systems use

5586-418: The armed forces, may use the same name to denote different types of organizations. An example is the "squadron". In most navies a squadron is a formation of several ships; in most air forces it is a unit; in the U.S. Army it is a battalion-sized cavalry unit; and in Commonwealth armies a squadron is a company-sized sub-unit. A table of organization and equipment (TOE or TO&E) is a document published by

To combat this threat, the U.S. Navy launched Operation Bumblebee to develop a ramjet-powered missile to destroy the launching aircraft at long range. The initial performance goal was to target an intercept at a horizontal range of 10 miles (16 km) and 30,000 feet (9,100 m) altitude, with

The use of the term "flight" originated in the United Kingdom to describe a collection of aircraft (typically four in

5880-496: The command of a designated flight leader. In U.S. Army Aviation , the equivalent organisational level of a flight is called a "platoon", while in U.S. Naval Aviation the flight is known as a "division". In Minuteman intercontinental ballistic missile units of the U.S. Air Force, a flight is composed of ten unstaffed launch facilities, remotely controlled by a staffed launch control center , containing two personnel. Five of these flights make up one missile squadron. The Air Force has

The five-star ranks of admiral of the fleet and fleet admiral have largely been out of regular use since the 1990s, with the exception of ceremonial or honorary appointments. Currently, all major navies ( blue-water and green-water navies) are commanded by an admiral of either four-star rank or three-star rank depending on relative size. Smaller naval forces, such as

Against late-war designs like the Boeing B-29 Superfortress or jet-powered designs like the Arado Ar 234 , flak would be essentially useless. This potential was already obvious by 1942, when Walther von Axthelm outlined the growing problems with flak defences that he predicted would soon be dealing with "aircraft speeds and flight altitudes [that] will gradually reach 1,000 km/h (620 mph) and between 10,000–15,000 m (33,000–49,000 ft)."

It has been suggested that the term was coined by technical sub-committee of the Committee of Imperial Defence , which was examining the British air arrangements around the same time.

All of these early systems were "heavyweight" designs with limited mobility and requiring considerable set-up time. However, they were also increasingly effective. By the early 1960s, the deployment of SAMs had rendered high-speed high-altitude flight in combat practically suicidal. The way to avoid this

A Schwarm (meaning swarm) as part of a Staffel (squadron) comprises four aircraft and can be further subdivided into twoships called Rotte (meaning rout, two aircraft). The tactical formation, however,

By the 1980s, the only remaining widespread use was point-defense of airfields and ships, especially against cruise missiles . By the 1990s, even these roles were being encroached on by new MANPADS and similar short-range weapons, like the RIM-116 Rolling Airframe Missile . Surface-to-air missiles are classified by their guidance , mobility, altitude and range . Missiles able to fly longer distances are generally heavier, and therefore less mobile. This leads to three "natural" classes of SAM systems; heavy long-range systems that are fixed or semi-mobile, medium-range vehicle-mounted systems that can fire on

The Soviet Union remained at the forefront of SAM development throughout its history; and Russia has followed suit. The early British developments with Stooge and Brakemine were successful, but further development was curtailed in the post-war era. These efforts picked up again with

More recently, however, it has become common for a flight to be led by a squadron leader (SqnLdr); a formal rank distinct from a squadron commander; equivalent to an army major or naval lieutenant commander . On rare occasions,

6762-503: The first example was a Royal Navy system known as the Holman Projector , used as a last-ditch weapon on smaller ships. The Germans also produced a similar short-range weapon known as Fliegerfaust , but it entered operation only on a very limited scale. The performance gap between this weapon and jet fighters of the post-war era was so great that such designs would not be effective. By the 1960s, technology had closed this gap to

6860-462: The first large-scale raids by the Allied air forces started. As the urgency of the problem grew, new designs were added, including Enzian and Rheintochter , as well as the unguided Taifun which was designed to be launched in waves. In general, these designs could be split into two groups. One set of designs would be boosted to altitude in front of the bombers and then flown towards them on

Dramatic changes followed, and by the end of the series, missions were carried out with additional chaff, ECM, Iron Hand, and other changes that dramatically changed the score. By the conclusion of the Linebacker II campaign, the shootdown rate of the S-75 against the B-52s was 7.52% (15 B-52s were shot down, 5 B-52s were heavily damaged for 266 missiles) During

Examples include the 2K12 Kub (SA-6) and 9K33 Osa (SA-8), MIM-23 Hawk , Rapier , Roland and Crotale . The introduction of sea-skimming missiles in the late 1960s and 1970s led to additional mid- and short-range designs for defence against these targets. The UK's Sea Cat

Within each departmental agency will be found administrative branches responsible for further agency business specialization work. In most countries,

7252-455: The missile's envelope and thereby greatly reducing their effectiveness in ground-attack roles. MANPAD systems are sometimes used with vehicle mounts to improve maneuverability, like the Avenger system. These systems have encroached on the performance niche formerly filled by dedicated mid-range systems. Ship-based anti-aircraft missiles are also considered to be SAMs, although in practice it

7350-611: The move, and short-range man-portable air-defense systems (MANPADS). Modern long-range weapons include the MIM-104 Patriot and S-300 systems, which have effective ranges on the order of 150 km (93 mi) and offer relatively good mobility and short unlimbering times. These compare with older systems with similar or less range, like the MIM-14 Nike Hercules or S-75 Dvina , which required fixed sites of considerable size. Much of this performance increase

7448-573: The opening of the Cold War, following the "Stage Plan" of improving UK air defences with new radars, fighters and missiles. Two competing designs were proposed for "Stage 1", based on common radar and control units, and these emerged as the RAF's Bristol Bloodhound in 1958, and the Army's English Electric Thunderbird in 1959. A third design followed the American Bumblebee efforts in terms of role and timeline, and entered service in 1961 as

7546-479: The physical arrangement or disposition of troops and weapons. Examples of formation in such usage include pakfront , panzerkeil , testudo formation , etc. A typical unit is a homogeneous military organization (either combat, combat-support or non-combat in capability) that includes service personnel predominantly from a single arm of service, or a branch of service, and its administrative and command functions are self-contained. Any unit subordinate to another unit

7644-399: The rank of commander. Corvettes , the smallest class of warship, are commanded by officers with the rank of commander or lieutenant-commander . Auxiliary ships, including gunboats , minesweepers , patrol boats , military riverine craft , tenders and torpedo boats are usually commanded by lieutenants , sub-lieutenants or warrant officers . Usually, the smaller the vessel, the lower

7742-479: The rank of the ship's commander. For example, patrol boats are often commanded by ensigns , while frigates are rarely commanded by an officer below the rank of commander. Historically, navies were far more rigid in structure. Ships were collected in divisions , which in turn were collected in numbered squadrons , which comprised a numbered fleet . Permission for a vessel to leave one unit and join another would have to be approved on paper. The modern U.S. Navy

7840-746: The resulting disagreements between the teams delayed serious consideration of a SAM for two years. Von Axthelm published his concerns in 1942, and the subject saw serious consideration for the first time; initial development programs for liquid- and solid-fuel rockets became part of the Flak Development Program of 1942. By this point serious studies by the Peenemünde team had been prepared, and several rocket designs had been proposed, including 1940's Feuerlilie , and 1941's Wasserfall and Henschel Hs 117 Schmetterling . None of these projects saw any real development until 1943, when

7938-475: The same branch (such as infantry) follow the same structural guidelines. The following table gives an overview of some of the terms used to describe army hierarchy in armed forces across the world. Whilst it is recognized that there are differences between armies of different nations, many are modeled on the British or American models, or both. However, many military units and formations go back in history for

8036-584: The same conclusions as the Germans regarding flak, the U.S. Army started its Project Nike developments in 1944. Led by Bell Labs , the Nike Ajax was tested in production form in 1952, becoming the first operational SAM system when it was activated in March 1954. Concerns about Ajax's ability to deal with formations of aircraft led to greatly updated version of the same basic design entering service in 1958 as

8134-446: The second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasingly pushed gun-based systems into the shortest-range roles. The American Nike Ajax

8232-683: The size of most nations' regiments or brigades. At the top of the ladder, what other nations would call an army group, the Red Army called a front . By contrast, during the same period the German Wehrmacht army groups, particularly on the Eastern Front , such as Army Group Centre significantly exceeded the above numbers, and were more cognate with the Soviet Strategic Directions . Naval organization at

8330-418: The smallest to the largest generally include identified as friend or foe (IFF) systems to help identify the target before being engaged. While IFF is not as important with MANPADs, as the target is almost always visually identified prior to launch, most modern MANPADs do include it. Long-range systems generally use radar systems for target detection, and depending on the generation of system, may "hand off" to

8428-554: The start, the large scale bomber raids of 1944 would have been impossible. The British developed unguided antiaircraft rockets (operated under the name Z Battery ) close to the start of World War II , but the air superiority usually held by the Allies meant that the demand for similar weapons was not as acute. When several Allied ships were sunk in 1943 by Henschel Hs 293 and Fritz X glide bombs , Allied interest changed. These weapons were released from stand-off distances, with

8526-430: The structure of public administration , often known as a ministry of defence or department of defense . These in turn manage military branches that themselves command formations and units specialising in combat, combat support and combat-service support . The usually civilian or partly civilian executive control over the national military organization is exercised in democracies by an elected political leader as

8624-407: The top levels and different armies and countries may also use traditional names, creating considerable confusion: for example, a British or Canadian armored regiment (battalion) is divided into squadrons (companies) and troops (platoons), whereas an American cavalry squadron (battalion) is divided into troops (companies) and platoons. In the French system (used by many African countries) the company

8722-511: The unit structure, since World War II, many brigades now have such support units, and since the 1980s, regiments also have been receiving support elements. A regiment with such support elements is called a regimental combat team in US military parlance, or a battlegroup in the UK and other forces. Canadian Army doctrine also includes the combat team which is a company of infantry augmented with tanks, or

8820-460: The upper hand. By the time of Operation Linebacker II in 1972, the Americans had gained critical information about the performance and operations of the S-75 (via Arab S-75 systems captured by Israel), and used these missions as a way to demonstrate the capability of strategic bombers to operate in a SAM saturated environment. Their first missions appeared to demonstrate the exact opposite, with

8918-544: The war, The Soviet Union supplied 7,658 SAMs to North Vietnam, and their defense forces conducted about 5,800 launches, usually in multiples of three. By the war's end, the U.S lost a total of 3,374 aircraft in combat operations. According to the North Vietnamese, 31% were shot down by S-75 missiles (1,046 aircraft, or 5.6 missiles per one kill); 60% were shot down by anti-aircraft guns; and 9% were shot down by MiG fighters. The S-75 missile system significantly improved

9016-463: The world, but uncommon in countries with English common law histories where civil police are employed to enforce the law, and there are tight restrictions on how the armed forces may be used to assist. It is common, at least in the European and North American militaries, to refer to the building blocks of a military as command s , formation s , and unit s . In a military context,

9114-477: Was a closely held secret until 1955. Early versions of the missile were available for purchase as early as 1952, but never entered operational service. The RSD 58 used beam riding guidance, which has limited performance against high-speed aircraft, as the missile is unable to "lead" the target to a collision point. Examples were purchased by several nations for testing and training purposes, but no operational sales were made. The Soviet Union began development of

9212-659: Was an early example that was designed specifically to replace the Bofors 40 mm gun on its mount, and became the first operational point-defense SAM. The American RIM-7 Sea Sparrow quickly proliferated into a wide variety of designs fielded by most navies. Many of these are adapted from earlier mobile designs, but the special needs of the naval role has resulted in the continued existence of many custom missiles. As aircraft moved ever lower, and missile performance continued to improve, eventually it became possible to build an effective man-portable anti-aircraft missile. Known as MANPADS ,

9310-401: Was proposed whereby a rocket would follow a searchlight beam onto a target. A selenium cell was mounted on the tip of each of the rocket's four tail fins, with the cells facing backwards. When one selenium cell was no longer in the light beam, it would be steered in the opposite direction back into the beam. The first historical mention of a concept and design of a surface-to-air missile in which

9408-651: Was seen generally; in November 1943 the Director of Gunnery Division of the Royal Navy concluded that guns would be useless against jets, stating "No projectile of which control is lost when it leaves the ship can be of any use to us in this matter." The first serious consideration of a SAM development project was a series of conversations that took place in Germany during 1941. In February, Friederich Halder proposed

9506-578: Was the first operational SAM system, and the Soviet Union's S-75 Dvina was the most-produced SAM system. Widely used modern examples include the Patriot and S-300 wide-area systems, SM-6 and MBDA Aster Missile naval missiles, and short-range man-portable systems like the Stinger and 9K38 Igla . The first known idea for a guided surface-to-air missile was in 1925, when a beam riding system

9604-524: Was to fly lower, below the line-of-sight of missile's radar systems. This demanded very different aircraft, like the F-111 , TSR-2 , and Panavia Tornado . Consequently, SAMs evolved rapidly in the 1960s. As their targets were now being forced to fly lower due to the presence of the larger missiles, engagements would necessarily be at short ranges, and occur quickly. Shorter ranges meant the missiles could be much smaller, which aided them in terms of mobility. By
