92-471: While there is no clear line between principal executive officers and inferior executive officers, principal officers are high-level officials in the executive branch of U.S. government such as department heads of independent agencies. In Humphrey's Executor v. United States , 295 U.S. 602 (1935), the Court distinguished between executive officers and quasi-legislative or quasi-judicial officers by stating that

184-679: A Private Finance Initiative with newly purchased Sikorsky S-92 and AgustaWestland AW189 aircraft. The new contract means that all UK SAR coverage is now provided by Bristow aircraft. In 2018, the RAF's vision of a future constellation of imagery satellites was initiated through the launch of the Carbonite-2 technology demonstrator. The 100 kg Carbonite-2 uses commercial off-the-shelf (COTS) components to deliver high-quality imagery and 3D video footage from space. The Royal Air Force celebrated its 100th anniversary on 1 April 2018. It marked

276-640: A wing commander and, for a fast-jet squadron, have an establishment of around twelve aircraft. Independent flights are so designated because they are explicitly smaller in size than a squadron. Many independent flights are, or have been, front-line flying units. For example, No. 1435 Flight carries out air defence duties for the Falkland Islands , with four Eurofighter Typhoon fighters based at RAF Mount Pleasant . Support capabilities are provided by several specialist wings and other units. Command, control, and support for overseas operations

368-470: A change in governing party or group of parties or a general election. Parliamentary systems have a head of government (who leads the executive, often called ministers ) normally distinct from the head of state (who continues through governmental and electoral changes). In the Westminster type of parliamentary system , the principle of separation of powers is not as entrenched as in some others. Members of

460-412: A command position. XOs in these positions typically assist a commander or deputy commander (or in the case of joint staffs or joint commands, a director) by managing day-to-day activities such as management of the senior officer's schedule, screening of documents or other products, and oversight of the senior officer's administrative support staff. Management of individual assets in the airline industry

552-410: A governance document. In the units of some military forces , the executive officer is the second-in-command , reporting to the commanding officer (CO). In most non-naval military services that are land-based (except the U.S. Army, where an executive officer is the second-in-command of certain units) or in joint military organizations, the executive officer is an administrative staff position versus

644-644: A minor role in the Korean War , with flying boats taking part. From 1953 to 1956 the RAF Avro Lincoln squadrons carried out anti- Mau Mau operations in Kenya using its base at RAF Eastleigh . The Suez Crisis in 1956 saw a large RAF role, with aircraft operating from RAF Akrotiri and RAF Nicosia on Cyprus and RAF Luqa and RAF Hal Far on Malta as part of Operation Musketeer . The RAF suffered its most recent loss to an enemy aircraft during

736-620: A quarter of Bomber Command's personnel were Canadian. Additionally, the Royal Australian Air Force represented around nine per cent of all RAF personnel who served in the European and Mediterranean theatres. During the Battle of Britain in 1940, the RAF defended the skies over Britain against the numerically superior German Luftwaffe . In what is perhaps the most prolonged and complicated air campaign in history,

828-488: A senior enlisted member, executive chief petty officers or executive petty officers are usually assigned to serve as second-in-command. On U.S. aircraft carriers , per Title 10 United States Code , both the captain (i.e., the commanding officer or CO) and the XO assigned to the ship are naval aviators or naval flight officers . Although not specified by 10 U.S.C., large, air-capable amphibious assault ships will have one of

920-585: A senior field grade (FGO) supporting a general officer. The U.S. Air Force uses the term executive officer for officers assigned as personal staff officers to general officers. Their role is similar to aides-de-camp in the U.S. Army and Marine Corps, and flag aides and flag lieutenants in the U.S. Navy and Coast Guard. A unique application of the term is executive officer to the Supreme Allied Commander Europe (SACEUR), and commander, United States European Command . This position

1012-594: A single Hawker Tempest F.6 in January 1949. Before Britain developed its own nuclear weapons , the RAF was provided with American nuclear weapons under Project E . However, following the development of its own arsenal, the British Government elected on 16 February 1960 to share the country's nuclear deterrent between the RAF and submarines of the Royal Navy, first deciding to concentrate solely on

1104-405: A squadron level organization, the second-in-command is typically termed the "director of operations" or "operations officer" (DO). These latter terms were previously used for similar positions at the group and wing level until renamed as the "operations group commander (OG/CC). The rank of an executive officer in the U.S. Air Force can vary from a junior officer supporting a mid level commander up to

1196-468: A staff administrative assistant to a senior officer, starting with a commander at the squadron level or above (e.g., squadron, group, wing, numbered air force, major command). In the other uniformed services, this position may be called an aide, an "executive assistant" or an adjutant . Like the Army, while experience gained as an XO is highly beneficial for an Air Force officer's professional development, it

1288-626: A support enabler role. A Control and Reporting Centre (CRC) at RAF Boulmer is tasked with compiling a Recognised Air Picture of UK air space and providing tactical control of the Quick Reaction Alert Force . In order to achieve this Boulmer is supported by a network of eight Remote Radar Heads (RRHs) spread the length of the UK. The UK operates permanent military airfields (known as Permanent Joint Operating Bases) in four British Overseas Territories . These bases contribute to

1380-490: A war that remained under low profile. The Konfrontasi against Indonesia in the early 1960s did see use of RAF aircraft, but due to a combination of deft diplomacy and selective ignoring of certain events by both sides, it never developed into a full-scale war. The RAF played a large role in the Aden Emergency between 1963 and 1967. Hawker Hunter FGA.9s based at RAF Khormaksar , Aden , were regularly called in by

1472-485: Is a managing partner, senior partner, or administrative partner. In the case of a limited liability company , an executive officer is any member, manager, or officer.

Groups are the subdivisions of operational commands and are responsible for certain types of capabilities or for operations in limited geographical areas. There are five groups subordinate to Air Command, of which four are functional and one is geographically focused: No. 1 Group is responsible for combat aircraft (comprising the Lightning Force and Typhoon Force) and

1748-403: Is becoming more common to hear the term XO. On larger ships of the Royal Navy, in which the XO holds the rank of commander , the XO is usually referred to simply as "the commander". The XO also heads the executive department. There are executive officer slots in each company , battalion , regiment , and brigade , though generally not at higher levels of command until the army level. The XO

1840-485: Is derived from the military terminology, where an executive officer or first officer , is the second in command of the aircraft. In a fixed wing aircraft, the first officer sits in the right-hand seat, but on a rotary wing aircraft, they sit on the left. Management of the airline as a whole is more in-line with the corporate example above. The term 'Executive officer' is used in the Indian Navy . Abbreviated as EXO ,

1932-425: Is not necessarily a prerequisite for a command position. However, it is often the norm that nearly all Air Force commanders will have been an XO at some point earlier in their careers. For officers holding second-in-command positions, the U.S. Air Force uses the titles of "vice commander" (CV), or "deputy commander" (CD) for an officer who serves as the second-in-command for an organization above squadron level.

3128-722: The Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has played a significant role in British military history . In particular, during the Second World War , the RAF established air superiority over Nazi Germany 's Luftwaffe during the Battle of Britain , and led the Allied strategic bombing effort. The RAF's mission

The Royal Air Force underwent rapid expansion prior to and during

3404-678: The London Eye , the RAF Memorial and (at 13.00) the Ministry of Defence building . Four major defence reviews have been conducted since the end of the Cold War: the 1990 Options for Change , the 1998 Strategic Defence Review , the 2003 Delivering Security in a Changing World and the 2010 Strategic Defence and Security Review (SDSR). All four defence reviews have resulted in steady reductions in manpower and numbers of aircraft, especially combat aircraft such as fast-jets. As part of

3496-548: The Royal Air Force , the term XO is informally used between officers and airmen, referring to the officer who is second-in-command. It is, however, formally used in the Royal Navy . In smaller vessels, such as submarines and frigates , the executive officer also holds the position of first lieutenant . Originally, the second-in-command was usually referred to as the first lieutenant (or as "number one"), although it

A flying squadron is an aircraft unit which carries out the primary tasks of the RAF. RAF squadrons are somewhat analogous to the regiments of the British Army in that they have histories and traditions going back to their formation, regardless of where they are based or which aircraft they are operating. They can be awarded standards and battle honours for meritorious service. Most flying squadrons are commanded by

The decision by the Court was that the Federal Trade Commission was a quasi-legislative body because of other powers it had, and therefore, the president could not fire an FTC member for political reasons. Congress can't retain removal power over officials with executive function ( Bowsher v. Synar ). However, statutes can restrict removal if not purely executive ( Humphrey ' s executor), but can't restrict removal of purely executive officer ( Myers v. United States , 272 U.S. 52 (1926)). The standard

6992-522: The great bulk of the RAF's bombing campaign, mainly due to Harris, but it also developed precision bombing techniques for specific operations, such as the infamous "Dambusters" raid by No. 617 Squadron , or the Amiens prison raid known as Operation Jericho . Following victory in the Second World War, the RAF underwent significant re-organisation, as technological advances in air warfare saw

7084-737: The highest scoring pilot of the war. Following a British victory, the RAF remained in the South Atlantic to provide air defence to the Falkland Islands, with the McDonnell Douglas Phantom FGR2 based at RAF Mount Pleasant which was built in 1984. With the end of the Cold War and the collapse of the Soviet Union, the RAF's focus returned to expeditionary air power . Since 1990, the RAF has been involved in several large-scale operations, including

7176-782: The latest 2010 Strategic Defence and Security Review, the BAE Systems Nimrod MRA4 maritime patrol aircraft was cancelled due to over spending and missing deadlines. Other reductions saw total manpower reduced by 5,000 personnel to a trained strength of 33,000 and the early retirement of the Joint Force Harrier aircraft, the BAE Harrier GR7/GR9 . In recent years, fighter aircraft on Quick Reaction Alert (QRA) have been increasingly required to scramble in response to Russian Air Force aircraft approaching British airspace. On 24 January 2014, in

7268-431: The northern sector of UK airspace, while Coningsby covers the southern sector. Typhoon pilot Flight Lieutenant Noel Rees describes how QRA duty works. "At the start of the scaled QRA response, civilian air traffic controllers might see on their screens an aircraft behaving erratically, not responding to their radio calls, or note that it's transmitting a distress signal through its transponder. Rather than scramble Typhoons at

7360-478: The occasion on 10 July 2018 with a flypast over London consisting of 103 aircraft. Between March 2020 and 2022, the RAF assisted with the response efforts to the COVID-19 pandemic in the United Kingdom as part of Operation Rescript . This saw the service provide repatriation flights and aeromedical evacuations of COVID-19 patients, drivers and call-handlers to support ambulance services and medics to assist with

7452-541: The officer is the second-in-command of a ship or shore establishment. In the Indian Army , second-in-command (2IC) is the designation used. The term XO is not used in most British Army or Royal Marines units, where the designation second-in-command (2i/c) is used as a formal appointment. However, the position does exist in some specialist regiments within the Royal Artillery where the exact duties vary. In

7544-404: The officer next in rank to the commander. As the direct representative of the commander, all orders issued by the executive officer shall have the same force and effect as though issued by the commander. The executive officer shall conform to and effectuate the policies and orders of the commander and shall be prepared to assume command at any time the need should arise." At higher levels of command,

7636-499: The physical defence and maintenance of sovereignty of the British Overseas Territories and enable the UK to conduct expeditionary military operations . Although command and oversight of the bases is provided by Strategic Command , the airfield elements are known as RAF stations. Four RAF squadrons are based overseas. No. 17 Test and Evaluation Squadron is based at Edwards Air Force Base , California, in

7728-402: The policing and inspection of the ship. When the ship goes to action stations, the XO confirms that the ship actually is ready for combat and reports this to the captain. The XO's own action station is in a separate part of the ship from that of the captain, so that a single hit will not likely incapacitate both officers. On small ships with no first lieutenant , gunnery officer , or navigator ,

7820-419: The same aircraft type. Some schools operate with only one squadron, and have an overall training throughput which is relatively small; some, like No. 3 Flying Training School , have responsibility for all Elementary Flying Training (EFT) in the RAF, and all RAF aircrew will pass through its squadrons when they start their flying careers. No. 2 Flying Training School and No. 6 Flying Training School do not have

7912-400: The second-in-command is the assistant division/wing commander or, in the case of a Marine Expeditionary Force (MEF), deputy commander. For those commands having a general officer (usually a brigadier general) in command without a designated assistant commander or deputy commander, such as a Marine Expeditionary Brigade (MEB) or Marine Logistics Group (MLG), the chief of staff (a colonel) is

8004-419: The second-in-command. Unlike their U.S. Navy counterparts, XOs of U.S. Marine Corps squadrons in U.S. Naval Aviation do not "fleet up" to become CO. The executive officer is the billet of the officer who is second-in-command. An XO is assigned to all ships, aviation squadrons, and shore units and installations, and is responsible to the captain for all ship's work, drills, exercises, personnel organization, and

8096-475: The staffing of hospitals, testing units and vaccination centres. Under Operation Broadshare , the RAF has also been involved with COVID-19 relief operations overseas, repatriating stranded nationals and delivering medical supplies and vaccines to British Overseas Territories and military installations. The UK's 20-year long operations in Afghanistan came to an end in August 2021, seeing the largest airlift since

8188-680: The two senior positions (CO or XO) occupied by a surface warfare officer and the other by a naval aviator or naval flight officer, alternating at each change of command. In naval aviation , in U.S. Navy squadrons (other than the Fleet Replacement Squadrons (FRS) and the Navy Flight Demonstration Squadron {viz., Blue Angels}), the XO will eventually "fleet up" to become the CO of that squadron after twelve to fifteen months as XO. This fleet up model

8280-555: The war was the strategic bombing campaign against Germany by Bomber Command. While RAF bombing of Germany began almost immediately upon the outbreak of war at first it was ineffectual; it was only later, particularly under the leadership of Air Chief Marshal Harris , that these attacks became increasingly devastating, from early 1943 onward, as new technology and greater numbers of superior aircraft became available. The RAF adopted night-time area bombing on German cities such as Hamburg and Dresden . Night time area bombing constituted

8372-423: Was also adopted in the late 2000s for XO and CO positions of both large amphibious assault ships (but not aircraft carriers) and Arleigh Burke -class guided missile destroyers. In addition to operational and tactical responsibilities, XOs also shoulder most of the CO's administrative burden, to include oversight of the command's administrative officer (if assigned) and administrative department. The term of XO in

8464-666: Was continued by the V bombers into the 1980s and until 1998 by the Panavia Tornado GR1 . For much of the Cold War the primary role of the RAF was the defence of Western Europe against potential attack by the Soviet Union , with many squadrons based in West Germany . The main RAF bases in RAF(G) were RAF Brüggen , RAF Gutersloh , RAF Laarbruch and RAF Wildenrath – the only air defence base in RAF(G). With
