A ballistic missile (BM) is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere , while most larger missiles travel outside the atmosphere. The type of ballistic missile with the greatest range is an intercontinental ballistic missile (ICBM). The largest ICBMs are capable of full orbital flight .

75-534: The PGM-11 Redstone was the first large American ballistic missile . A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO 's Cold War defense of Western Europe. It was the first US missile to carry a live nuclear warhead , in the 1958 Pacific Ocean weapons test Hardtack Teak . The Redstone

150-613: A 700-mile (1,130 km) apogee . Pegasus would have used the Pershing erector-launcher and could be placed in any open area. Martin seems to have targeted the nascent European space program, but this system was never developed. In 1965, the Army contracted with the Applied Physics Laboratory (APL) of Johns Hopkins University to develop and implement a test and evaluation program. APL provided technical support to

225-651: A Ford M656 truck for U.S. Army units and a Magirus-Deutz or MAN SE for German Air Force units. Launch activation was performed from a remote fire box that could be deployed locally or mounted in the battery control central (BCC). One PTS controlled three launchers— when one launch count was complete, ten large cables were unplugged from the PTS and the PTS was moved up and connected to the next launcher. Missile and power station upgrades in 1974 provided easier access to missile components, reduce maintenance and improved reliability. A new digital guidance and control computer combined

300-455: A ballistic missile with a range of about 500–750 nautical miles (930–1,390 km; 580–860 mi). Later that year, Secretary of Defense Charles Erwin Wilson issued the "Wilson Memorandum" that removed from the U.S. Army all missiles with a range of 200 miles (320 km) or more. The United States Department of Defense (DoD) rescinded the memorandum in 1958 and ABMA began development of

375-516: A control box, the ST-120 inertial navigation system in the guidance section rotated into alignment and the north direction programmed into the computer. In 1961, Martin proposed a satellite launch system based on the Pershing. Named Pegasus , it would have had a lighter, simplified guidance section and a short third stage booster. A 60-pound (27 kg) payload could be boosted to a 210-mile (340 km) circular orbit , or to an elliptical orbit with

450-424: A fuel mixture of 25 percent water–75 percent ethyl alcohol with liquid oxygen (LOX) used as the oxidizer . Later Redstones used Hydyne, 60% unsymmetrical dimethylhydrazine (UDMH) and 40% diethylenetriamine (DETA), as the fuel. The missile body consisted of an aft unit containing the instrument compartment, and the warhead unit containing the payload compartment and the radar altimeter fuze. The missile body

525-639: A joint Army/ Department of Energy study concluded that it was technically and financially feasible to replace the W50 warhead carried by Pershing 1a with the W85 warhead developed for Pershing II. However, with the signing of the INF Treaty, development on the conversion was terminated. The Pershing II Weapon System was a solid-fueled two-stage ballistic missile designed and built by Martin Marietta to replace

600-469: A lower throw-weight. The primary reasons to choose a depressed trajectory are to evade anti-ballistic missile systems by reducing the time available to shoot down the attacking vehicle (especially during the vulnerable burn-phase against space-based ABM systems) or a nuclear first-strike scenario. An alternate, non-military purpose for a depressed trajectory is in conjunction with the spaceplane concept with use of airbreathing jet engines , which requires

675-400: A missile's warheads , reentry vehicles , self-contained dispensing mechanisms, penetration aids , and any other components that are part of the delivered payload, and not of the rocket itself (such as the launch rocket booster and launch fuel). Throw-weight may refer to any type of warhead, but in normal modern usage, it refers almost exclusively to nuclear or thermonuclear payloads. It

750-411: A new table of organization and equipment (TOE); an infantry battalion was added to provide additional security; and the 56th Artillery Group was reorganized and redesignated the 56th Field Artillery Brigade. Due to the nature of the weapon system, officer positions were increased by one grade: batteries were commanded by a major instead of a captain ; battalions were commanded by a colonel ; and

825-585: A new engine that burned a fuel mixture known as hydyne and under the name of the Jupiter C/Juno 1 was used for the first successful US space launch of the Explorer 1 satellite in 1958. The Mercury-Redstone Launch Vehicle was a derivation of the Redstone with a fuel tank increased in length by 6 feet (1.8 m) and was used on 5 May 1961 to launch Alan Shepard on his sub-orbital flight to become

900-626: A portion thereof would be combat alert status (CAS) on a permanent hard site, covering assigned targets. In peacetime the four batteries of each battalion rotated through four states or conditions of alert readiness, the highest being that of the CAS battery. The purpose of this rotation was to assume the CAS status, to share the burden of CAS responsibility, to provide time for field tactical training and equipment maintenance, and to give ample leave and pass time to personnel without adverse impact on operational requirements. During periods of increased tension,

975-472: A range of about 1,400 km. In order to cover large distances, ballistic missiles are usually launched into a high sub-orbital spaceflight ; for intercontinental missiles, the highest altitude ( apogee ) reached during free-flight is about 4,500 kilometers (2,800 mi). A ballistic missile's trajectory consists of three parts or phases : the boost phase, the mid-course phase and the terminal phase. Special systems and capabilities are required to facilitate

1050-415: A solid-propellant motor cannot be turned off, the missile used thrust reversal and case venting for a selective range. Splice bands and explosive bolts attached the rocket motors. The missile was controlled by an analog guidance computer using a ball-and-disk integrator and a control computer. As directed by the onboard computers, the bolts exploded and ejected the splice band. Another squib would open

1125-561: A spare Sparta for Australia's first satellite launch, WRESAT , in November 1967. Ballistic missile These missiles are in a distinct category from cruise missiles , which are aerodynamically guided in powered flight and thus restricted to the atmosphere. One modern pioneer ballistic missile was the A-4, commonly known as the V-2 developed by Nazi Germany in the 1930s and 1940s under

1200-794: A yield of 3.8 megatons. Chrysler Corporation was awarded the prime production contract, to be made at the newly renamed Michigan Ordnance Missile Plant in Warren, Michigan. The navy-owned facility was previously known as the Naval Industrial Reserve Aircraft Plant used for jet engine production. Following the cancellation of a planned jet engine program, the facility was made available to the Chrysler Corporation for missile production, and began missile and support equipment production in 1952. Rocketdyne Division of North American Aviation Company provided

1275-651: The 1st Missile Battalion, 81st Artillery to McCully Barracks in Wackernheim . Each missile battalion had four launchers. The 2nd Missile Battalion, 79th Artillery Regiment formed for deployment to South Korea in February 1964. The deployment was placed on hold and the battalion supported the 56th Artillery Group and the German Air Force missile wings when they launched missiles from White Sands Missile Range. The 85th U.S. Army Field Artillery Detachment

1350-796: The Air Force Missile Test Center (present-day Cape Canaveral Air Force Station ) in Florida. The Martin Company subsequently began construction of their Sand Lake facility in Orlando, Florida which opened in late 1957. Edward Uhl , the co-inventor of the bazooka , was the vice-president and general manager of the new factory, which continues to operate today as the Lockheed Martin Missiles and Fire Control facility. The U.S. Army began studies in 1956 for

1425-736: The Convair Division of General Dynamics , the Firestone Corp. , the Sperry-Rand Company , and the Martin Company. The Secretary of the Army , Wilber M. Brucker , the former governor of Michigan – was apparently under pressure from his home state to award the contract to a company in Michigan. Chrysler was the only contractor from Michigan, but Medaris persuaded Brucker to leave the decision entirely in

1500-674: The German V-2 rocket , developed by a team of predominantly German rocket engineers under the leadership of Wernher von Braun , that had been brought to the United States after World War II as part of Operation Paperclip . A product of the Army Ballistic Missile Agency (ABMA) at Redstone Arsenal in Huntsville, Alabama , Redstone was designed as a surface-to-surface missile for the U.S. Army. It

1575-599: The Pershing Operational Test Unit (POTU), identified problem areas and improved the performance and survivability of the Pershing systems. In 1964 a series of operational tests and follow-on tests were performed to determine Pershing reliability. The Secretary of Defense then requested that the Army define the modifications required to make Pershing suitable for the Quick Reaction Alert (QRA) role. The Pershing 1a development program

1650-522: The Redstone rocket family which holds a number of firsts in the US space program, notably launching the first US astronaut. It was retired by the Army in 1964 and replaced by the solid-fueled MGM-31 Pershing . Surplus missiles were widely used for test missions and space launches, including the first US man in space, and in 1967 the launch of Australia's first satellite . Redstone was a direct descendant of

1725-479: The brigade was commanded by a brigadier general . Pershing 1a was deployed with three U.S. battalions in Europe and two German Air Force wings. Each battalion or wing had 36 mobile launchers. The constitution of West Germany prohibited owning nuclear weapons, thus control of the nuclear warheads remained in the hands of the U.S. Army. During peacetime operations, a portion of the Pershing 1a assets were deployed on

1800-504: The warhead , the missile fins and the azimuth laying set used to position the missile. The PTS/PS carrier transported the programmer test station (PTS) and power station (PS). A fourth vehicle transported the Radio Terminal Set. The four vehicles were known as the land train. The PTS featured rapid missile checkout and countdowns, with complete computer control, and automatic self-test and malfunction isolation. Additionally,

1875-799: The Earth's atmosphere at very high velocities, on the order of 6–8 kilometers per second (22,000–29,000 km/h; 13,000–18,000 mph) at ICBM ranges. During the beginning of this phase, the missile's trajectory is still relatively well defined, though as the missile reaches the heavier layers of atmosphere it is increasingly influenced by gravity and aerodynamic drag, which can affect its landing. Ballistic missiles can be launched from fixed sites or mobile launchers, including vehicles (e.g., transporter erector launchers ), aircraft , ships , and submarines . Ballistic missiles vary widely in range and use, and are often divided into categories based on range. Various schemes are used by different countries to categorize

1950-798: The European-based MGM-13 Mace cruise missiles deployed by the United States Air Force and the German Air Force . Development began in 1958, with the first test missile fired in 1960, the Pershing 1 system deployed in 1963 and the improved Pershing 1a deployed in 1969. The U.S. Army replaced the Pershing 1a with the Pershing II Weapon System in 1983 while the German Air Force retained Pershing 1a until all Pershings were eliminated in 1991. The U.S. Army Missile Command (MICOM) managed

2025-510: The PTS to remain connected to all three launchers allowing all three missiles to stay hot. The automatic reference system (ARS) eliminated the theodolites previously used to lay and orient the missile. It included a north-seeking gyro and a laser link to the ST-120 that more quickly oriented the missile. After the Pershing II explosion in 1985, the Pershing 1a launchers of the German Air Force were retrofitted with ballistic shields. In 1987

2100-408: The PTS would perform tests that simulated airborne missile operation, programmed the trajectory of the missile and controlled the firing sequence. Plug-in micromodules increased maintainability and allowed the PTS operator to perform 80% of all repairs at the firing position. A turbine driven Power Station mounted behind the PTS, provided the primary electrical and pneumatic power and conditioned air for

2175-451: The Pershing 1a Field Artillery Missile System as the United States Army 's primary nuclear-capable theater-level weapon. The U.S. Army replaced the Pershing 1a with the Pershing II in 1983 while the German Air Force retained Pershing 1a until all Pershings were eliminated in 1991. [REDACTED]   United States : United States Army [REDACTED] West Germany : German Air Force The Pershing systems were eliminated after

2250-462: The QRA mission. The remainder would be conducting field training or were maintained in kasernes awaiting alert. The system was designed to be highly mobile, permitting its dispersal to clandestine sites in times of alert or war and was deployed at distances greater than 100 km behind the forward edge of battle area or political border. Owing to its mobility and setback, Pershing was considered one of

2325-589: The Soviets to maintain higher throw-weight than an American force with a roughly comparable number of lower-payload missiles. The missiles with the world's heaviest payloads are the Russian SS-18 and Chinese CSS-4 and as of 2017 , Russia was developing a new heavy-lift, liquid-propellant ICBM called the Sarmat . Throw-weight is normally calculated using an optimal ballistic trajectory from one point on

2400-651: The USSR's infrastructure and ability to wage war. With the arrival of newer solid-fueled missiles that could be stored and not require fueling before launch, Redstone was rendered obsolete and production ended in 1961. The 40th Artillery Group was deactivated in February 1964 and 46th Artillery Group was deactivated in June 1964, as Redstone missiles were replaced by the Pershing missile in the U.S. Army arsenal. All Redstone missiles and equipment deployed to Europe were returned to

2475-401: The United States by the third quarter of 1964. In October 1964, the Redstone missile was ceremonially retired from active service at Redstone Arsenal. Redstone was capable of flights from 57.5 to 201 miles (92.5 to 323.5 km). It consisted of a thrust unit for powered flight and a missile body for overall missile control and payload delivery on target. During powered flight, Redstone burned

2550-411: The atmosphere from space. However, in common military terminology, the term "hypersonic ballistic missile" is generally only given to those that can be maneuvered before hitting their target and don't follow a simple ballistic trajectory . Throw-weight is a measure of the effective weight of ballistic missile payloads . It is measured in kilograms or tonnes . Throw-weight equals the total weight of

2625-445: The ballistic missile to remain low enough inside the atmosphere for air-breathing engines to function. In contrast, a "lofted" trajectory is frequently used for testing purposes, as it reduces the range of the missile (allowing for a controlled and observed impact), as well as signals a lack of hostile intention with the test. The following ballistic missiles have been used in combat: Pershing missile The MGM-31A Pershing

2700-529: The boost phase. The mid-course phase is the longest in the missile's trajectory, beginning with the conclusion of powered flight. When the fuel is exhausted, no more thrust is provided and the missile enters free flight. During this phase the missile, now largely consisting of a warhead or payload and possibly defensive countermeasures and small propulsion systems for further alignment toward its target, will reach its highest altitude and may travel in space for thousands of kilometres (or even indefinitely, in

2775-415: The carriers and air-transported in fourteen CH-47 Chinook loads. The missile was positioned or laid in on a pre-surveyed site with a system of two theodolites and a target card. Directional control passed from one theodolite to the one next to the missile. The missile then oriented to north by an operator using a horizontal laying theodolite aimed at a window in the guidance section of the missile. Using

2850-454: The case of some fractional-orbital capable systems) at speeds of up to 7.5 to 10 kilometres per second (4 to 5 nautical miles per second). The last phase in the missile's trajectory is the terminal or re-entry phase, beginning with the re-entry of the missile into the Earth's atmosphere (if exoatmospheric ) where atmospheric drag plays a significant part in missile trajectory, and lasts until missile impact . Re-entry vehicles re-enter

2925-687: The class of ballistic missile. The missile was initially called the Redstone-S , where the S meant solid propellant (and the name Redstone came from the Redstone missile it was supposed to replace), but renamed to Pershing in honor of General of the Armies John J. Pershing . ABMA selected seven companies to develop engineering proposals: Chrysler , the Lockheed Corporation , the Douglas Aircraft Company ,

3000-599: The concept of Zero Defects that enhanced the production and reliability of the system. The first launch of the XM14 R&;D Pershing 1 test missile (P-01) was on 25 February 1960. The first launch from the tactical transporter erector launcher (TEL) was on 26 July 1960 (P-06). For training there was an inert Pershing 1 missile designated XM19. In June 1963, the XM14 and XM19 Pershing missiles were redesignated as XMGM-31A and XMTM-31B, respectively. The production version of

3075-410: The control computer in the missile were replaced by a single digital guidance and control computer. The main distributor in the missile that routed power and signals was replaced with a new version. The missile used a rotary inverter to convert DC to AC that was replaced by a solid-state static inverter. The power station was improved for accessibility and maintenance. Further improvements in 1976 allowed

3150-474: The development and improvements while the Field Artillery Branch deployed the systems and developed tactical doctrine. George Bunker, president of the Martin Company , paid a courtesy call on General John Medaris , USA, of the Army Ballistic Missile Agency (ABMA) at Redstone Arsenal , Alabama in 1956. Medaris noted that it would be helpful to the Army if there was a missile plant near

3225-509: The direction of Wernher von Braun . The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris , followed by an attack on London two days later. By the end of World War II in Europe in May 1945, more than 3,000 V-2s had been launched. In addition to its use as a weapon, a vertically launched V-2 became the first human-made object to reach outer space on June 20, 1944. The R-7 Semyorka

3300-403: The firing batteries of each battalion were deployed to previously unused field tactical sites. At these sites, they assumed responsibility for coverage of all assigned targets. During the transition from the peacetime to full combat status, coverage was maintained on the highest priority targets that were assigned to the peacetime CAS batteries. Once all firing batteries were at their field sites,

3375-444: The firing elements of the battalions were deployed by platoons, which were then separated from each other geographically to reduce vulnerability. The platoons then moved to new firing positions on a random schedule to increase survivability. The M790 erector launcher (EL) was a modified low-boy flat-bed trailer towed by a Ford M757 5-ton tractor. The erection booms used a 3,000 psi pneumatic over hydraulic system that could erect

3450-488: The firing of a platoon's three missiles in quick succession and from any site without the need for surveying. The Automatic Reference System (ARS) used an optical laser link and a north-seeking gyro with encode to eliminate the need for pre-selected and surveyed points. The Sequential Launch Adapter connected the PTS to three missiles, eliminating the need to cable and uncable each launcher. A total of 754 MGM-31A missiles were built. The battalions in Europe reorganized under

3525-418: The five ton missile from horizontal to vertical in nine seconds. Due to the overall missile length and for security, the warhead was not mated during travel. It was stored in a carrier and mated using a hand-pumped davit after the launcher was emplaced. The EL was pulled by a Ford M757 tractor for U.S. Army units and by a Magirus-Deutz Jupiter 6×6 for German Air Force units. The PTS and PS were mounted on

3600-406: The functions of the analog control computer and the analog guidance computer into one package. The mean time to repair decreased from 8.7 hours to 3.8 hours and the mean time between failures increased from 32 hours to 65 hours. More modifications in 1976 greatly reduced the launch time. The sequential launch adapter (SLA) was an automatic switching device mounted in a 10-ton trailer that allowed

3675-479: The hands of the ABMA. After a selection process by General Medaris and Dr. Arthur Rudolph , the Martin Company (later Martin Marietta after a merger in 1961) was awarded a CPFF (cost-plus-fixed-fee) contract for research, development, and first production of the Pershing system under the technical supervision and concept control of the government. Martin's quality control manager for the Pershing, Phil Crosby developed

3750-509: The missile and ground support equipment at the firing position. Collins Radio Company produced the AN/TRC-80 Radio Terminal Set specifically for the Pershing system. The "Track 80" used an inflatable dish antenna to provide line-of-sight or tropospheric-scatter voice and teleprinter communications between missile firing units and higher headquarters. The erector-launcher, PTS, PS and RTS could be removed from

3825-502: The most survivable theater nuclear weapons ever deployed in Europe. The primary mission in the Supreme Allied Commander, Europe scheduled plan took one of two forms: peacetime or an increased state of readiness called the period of tension. Different levels or techniques of tasking were used for these mission forms. The peacetime Quick Reaction Alert role required that for each battalion or wing, one firing battery or

3900-539: The motor nozzles and air vanes on the motor case steered the missile. The onboard analog guidance computer and the Eclipse-Pioneer ST-120 (Stable Table-120) inertial navigation system provided guidance. The warhead could be conventional explosive or a W50 nuclear weapon with three yield options— the Y1 with 60 kiloton yield, Y2 with 200 kiloton yield and Y3 with 400 kiloton yield; the conventional warhead

3975-559: The organization of ten missile battalions: one at Fort Sill , one in Korea and eight in West Germany; this was eventually reduced to one battalion at Fort Sill and three in West Germany. Each missile battalion organized at Fort Sill for deployment. The first tactical Pershing unit was the 2nd Missile Battalion, 44th Artillery Regiment , followed by the 4th Missile Battalion, 41st Artillery Regiment deployed to Schwäbisch Gmünd and

4050-644: The ranges of ballistic missiles: Long- and medium-range ballistic missiles are generally designed to deliver nuclear weapons because their payload is too limited for conventional explosives to be cost-effective in comparison to conventional bomber aircraft . A quasi-ballistic missile is a category of SRBM that is largely ballistic but can perform maneuvers in flight or make unexpected changes in direction and range. Large guided MLRS rockets with range comparable to an SRBM are sometimes categorized as quasi-ballistic missiles. Many ballistic missiles reach hypersonic speeds (i.e. Mach 5 and above) when they re-enter

4125-641: The ratification of the Intermediate-Range Nuclear Forces Treaty on 27 May 1988. The missiles began to be withdrawn in October 1988 and the last of the missiles were destroyed by the static burn of their motors and subsequently crushed in May 1991 at the Longhorn Army Ammunition Plant near Caddo Lake , Texas. Although not covered by the treaty, West Germany agreed unilaterally to the removal of

4200-511: The rocket engines; Ford Instrument Company, division of Sperry Rand Corporation , produced the guidance and control systems; and Reynolds Metals Company fabricated fuselage assemblies as subcontractors to Chrysler. In 1955, the Jupiter-C rocket (not to be confused with the later, unrelated Jupiter IRBM) was developed as an enhanced Redstone for atmospheric and reentry vehicle tests. It had elongated propellant tanks for increased burn time and

4275-409: The rocket explode?" An exasperated von Braun said "It exploded because the damn sonofabitch blew up!" Von Braun pressured the ABMA team to improve reliability and workmanship standards, allegedly remarking that "Missile reliability will require that the target area is more dangerous than the launch area." Subsequent test flights went better and the Army declared Redstone operational in mid-1955. Testing

4350-536: The second person and first American in space. It retained the Jupiter C's longer propellant tanks, but went back to using ethyl alcohol/water for propellant instead of hydyne. From 1966 to 1967, a series of surplus modified Redstones called Spartas were launched from Woomera, South Australia , as part of a joint U.S.–United Kingdom–Australian research program aimed at understanding re-entry phenomena. These Redstones had two solid fuel upper stages added. The U.S. donated

4425-518: The successful passage from one phase to the other. The boost phase is the powered flight portion, beginning with the ignition of the engines and concluding with the end of powered flight. The powered flight portion can last from a few tenths of seconds to several minutes and can consist of multiple rocket stages. Internal computers keep the missile aligned on a preprogrammed trajectory. On multi-stage missiles , stage separation (excluding any post-boost vehicles or MIRV bus) occurs primarily during

4500-435: The surface of the Earth to another. A "minimum-energy trajectory" maximizes the total payload (throw-weight) using the available impulse of the missile. By reducing the payload weight, different trajectories can be selected, which can either increase the nominal range or decrease the total time in flight. A depressed trajectory is non-optimal, as a lower and flatter trajectory takes less time between launch and impact but has

4575-527: The tactical missile was later designated as MGM-31A and the XMTM-31B designation was dropped. President Eisenhower viewed the Pershing missile when he visited Cape Canaveral on 11 February 1960, and at Fort Benning on 5 May 1960 as part of Project MAN (Modern Army Needs). President Kennedy viewed Pershing three times: as part of the inaugural parade in 1961, at Fort Bragg on 12 October 1961, and at White Sands Missile Range in 1963. Plans were for

4650-428: The thrust reversal ports in the forward end of the stage and ignite the propellant in the forward end, causing the motor to reverse direction. Testing found that the second stage would draft behind the warhead and cause it to drift off course, so explosive charges on the side of the motor opened the case and vented the propellant. The range could be graduated but the maximum was 740 kilometres (400 nmi). Jet vanes in

4725-489: Was a Quick Reaction Alert system and so had faster vehicles, launch times and newer electronics. The total number of launchers increased from 8 to 36 per battalion. Production of the Pershing 1a missile ended in 1975 and reopened in 1977 to replace missiles expended in training. Pershing 1a was further improved in 1971 with the Pershing Missile and Power Station Development Program. The analog guidance computer and

4800-568: Was a direct descendant of the German V-2 rocket , developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the 6,900 lb (3,100 kg) W39 and its reentry vehicle to a range of about 175 miles (282 km). Redstone's prime contractor was the Chrysler Corporation. The Redstone spawned

4875-472: Was approved in 1965, the original Pershing renamed to Pershing 1 and Martin Marietta received the Pershing 1a production contract in 1967. Project SWAP replaced all the Pershing equipment in Germany by mid-1970 and the first units quickly achieved QRA status. Secretary of Defense Robert McNamara directed that the U.S. Air Force's MGM-13 Mace missile would be replaced by the Pershing 1a in 1965. Pershing 1a

4950-473: Was introduced to reduce problems with LOX turbopump cavitation. The third Redstone flight on 5 May was a total loss as the engine cut off one second after launch, causing the rocket to fall back on the pad and explode. After this incident, Major General Holger Toftoy pressured Wernher von Braun for the cause of the failure. The latter replied that he had no idea, but they would review telemetry and other data to find out. Toftoy persisted, asking "Wernher, why did

5025-540: Was moved from LC-4 to the bigger LC-5 and LC-6. The Redstone program proved to be a bone of contention between the Army and Air Force due to their different ideas of nuclear warfare. The Army favored using small warheads on mobile missiles as tactical battlefield weapons while the Air Force, which was responsible for the ICBM program, wanted large trans-continental missiles that could strike Soviet targets and rapidly cripple

5100-498: Was named for the arsenal on 8 April 1952, which traced its name to the region's red rocks and soil . The first Redstone lifted off from LC-4A at Cape Canaveral on 20 August 1953. It flew for one minute and 20 seconds before suffering an engine failure and falling into the sea. Following this partial success, the second test was conducted on 27 January 1954, this time without a hitch as the missile flew 55 miles (89 km). After these first two prototypes were flown, an improved engine

5175-443: Was never deployed. The Pershing 1 firing platoon consisted of four M474 tracked-vehicles manufactured by FMC Corporation — by comparison, Redstone needed twenty vehicles. The transporter erector launcher (TEL) transported the two stages and the guidance section as an assembly and provided the launch platform after the warhead was mated. It used a removable erector launcher manufactured by Unidynamics. The warhead carrier transported

5250-586: Was once also a consideration in the design of naval ships and the number and size of their guns.
