The 2.25-Inch Sub-Caliber Aircraft Rocket, or SCAR, was an American unguided rocket developed by the United States Navy during World War II and used for sub-caliber rocket training. Capable of simulating the aerial rockets then coming into operational service, the SCAR was used to train pilots in the use of the new type of weapon, and continued in service throughout the 1950s.
With the introduction of the 3.5-Inch and 5-Inch Forward Firing Aircraft Rockets, a need arose to train aircraft pilots in the proper tactics for the use of the new weapons. This requirement resulted in the development of a dedicated training rocket by the U.S. Navy. [2]
Designated 2.25-Inch Sub-Caliber Aircraft Rocket, the resulting rocket was a joint project between the Bureau of Ordnance and the National Defense Research Committee. [2] As its name implied, the rocket was designed as a sub-calibre weapon compared to the FFAR, being only 2.25 inches (57 mm) in diameter, but weighted to be ballistically similar to the larger operational weapons. [2] Varying the amount of propellant in the SCAR's motor could produce accurate simulations of either type of FFAR's flight characteristics. [2]
Following development, SCAR entered full-scale production in January 1945; by July, fully half of the U.S. Navy's rocket production for aircraft use consisted of SCAR rockets. [3] SCAR was widely used during the latter part of World War II as a training round for the FFAR and, later, the High Velocity Aircraft Rocket. [2]
Following the end of the war, it remained in production, continuing in operational service throughout the 1950s. [4] Budget cutbacks prior to the outbreak of the Korean War meant that the SCAR was the only rocket used in training by the majority of pilots. [5]
Despite its small size, SCAR could be hazardous; in 1957, an injury aboard the aircraft carrier USS Kearsarge was caused by the unintended ignition of a SCAR rocket. [6] As recently as 2004, expended SCAR rockets were still occasionally being found in areas that had been used as bombing ranges during World War II. [7]
The Mk 4 Folding-Fin Aerial Rocket (FFAR), also known as "Mighty Mouse", was an unguided rocket used by United States military aircraft. It was 2.75 inches (70 mm) in diameter. Designed as an air-to-air weapon for interceptor aircraft to shoot down enemy bombers, it primarily saw service as an air-to-surface weapon. The FFAR has been developed into the modern Hydra 70 series, which is still in service.
The RP-3 was a British air to ground rocket projectile introduced during the Second World War. The "3 inch" designation referred to the nominal diameter of the rocket motor tube. The use of a 60-pound (27 kg) warhead gave rise to the alternative name of the "60-pound rocket". Though primarily an air-to-ground weapon, it saw limited use in other roles. They were generally used by British fighter-bomber aircraft against targets such as tanks, trains, motor transport and buildings, as well as by Coastal Command and Royal Navy aircraft against U-boats and ships.
The AUM-N-2 Petrel, also known as Kingfisher C and AUM-2, was an air-to-surface missile produced as part of Project Kingfisher for the United States Navy. Intended for use against enemy surface ships and surfaced submarines, giving aircraft the ability to deliver aerial torpedoes from outside the range of defensive armament, it saw brief operational service in the late 1950s. The project was never considered a high priority by the Navy however, as it was useless against submerged submarines, which were considered the greatest potential threat.
The Zuni 5-inch Folding-Fin Aircraft Rocket (FFAR), or simply Zuni, is a 5.0 in (127 mm) unguided rocket developed by the Hunter-Douglas Division of Bridgeport Brass Company and deployed by the United States armed forces, and the French Air Force. The rocket was developed for both air-to-air and air-to-ground operations. It can be used to carry various types of warheads, including chaff for countermeasures. It is usually fired from the LAU-10 rocket pod holding four rockets.
Project Kingfisher was a weapons-development program initiated by the United States Navy during the latter part of World War II. Intended to provide aircraft and surface ships with the ability to deliver torpedoes to targets from outside the range of defensive armament, six different missile concepts were developed; four were selected for full development programs, but only one reached operational service.
The High Velocity Aircraft Rocket, or HVAR, also known by the nickname Holy Moses, was an American unguided rocket developed during World War II to attack targets on the ground from aircraft. It saw extensive use during both World War II and the Korean War.
The 5-inch Forward Firing Aircraft Rocket or FFAR was an American rocket developed during World War II for attack from airplanes against ground and ship targets.
The Hopi was an air-to-surface missile developed by the United States Navy's Naval Ordnance Test Station. Intended to provide a medium-range nuclear capability for carrier aircraft, the missile reached the flight test stage during 1958, but the project was cancelled following testing and no production was undertaken.
The Bombardment Aircraft Rocket, also known as BOAR, the Bureau of Ordnance Aircraft Rocket, and officially as the 30.5-Inch Rocket, Mark 1, Mod 0, was an unguided air-to-surface rocket developed by the United States Navy's Naval Ordnance Test Station during the 1950s. Intended to provide a standoff nuclear capability for carrier-based aircraft, the rocket entered operational service in 1956, remaining in service until 1963.
The RAM, also known as the 6.5-Inch Anti-Tank Aircraft Rocket or ATAR, was an air-to-ground rocket used by the United States Navy during the Korean War. Developed rapidly, the rocket proved successful but was phased out shortly after the end of the conflict.
The Gimlet was an unguided air-to-air and air-to-surface rocket developed by the United States Navy during the early 1950s. Although it proved successful in testing and was ordered into large-scale production, the arrival of the guided missile as a practical and reliable weapon resulted in the cancellation of the Gimlet rocket in 1957.
The Creative Research On Weapons or Crow program was an experimental missile project developed by the United States Navy's Naval Air Missile Test Center during the late 1950s. Intended to evaluate the solid-fueled integral rocket/ramjet (SFIRR) method of propulsion as well as solid-fueled ramjet engines, flight tests were conducted during the early 1960s with mixed success.
The 3.5-inch Forward Firing Aircraft Rocket, or 3.5-Inch FFAR, was an American rocket developed during World War II to allow aircraft to attack enemy submarines at range. The rocket proved an operational success, and spawned several improved versions for use against surface and land targets.
The Piper LBP was a glide bomb, or "Glomb", developed by Piper Aircraft for the United States Navy during World War II. Developed as one of three "Glomb" aircraft, the inherent limitations of the Glomb and the technology of the time, combined with difficulties encountered in testing of the prototype, led to the production contract for the LBP-1 being reduced, then cancelled, with none of the Glomb aircraft ever seeing operational service.
The Taylorcraft LBT was a glider designed and built by Taylorcraft during World War II, in response to a United States Navy requirement for a glide bomb. One of three prototype "Glomb" models ordered by the Navy, the LBT suffered from technical and performance difficulties, and was cancelled early in production, none of the aircraft seeing operational service.
The AGR-14 ZAP was an air-to-surface unguided rocket developed by the United States Navy in the late 1960s. Intended for use in the suppression of enemy air defenses role, the rocket reached the flight-testing stage before being cancelled.
The ASM-N-5 Gorgon V was an unpowered air-to-surface missile, developed by the Glenn L. Martin Company during the early 1950s for use by the United States Navy as a chemical weapon delivery vehicle. Developed from the earlier PTV-N-2 Gorgon IV test vehicle, the program was cancelled without any Gorgon Vs seeing service.
The AAM-N-4 Oriole was an early American air-to-air missile, developed by the Glenn L. Martin Company for the United States Navy. Designed for launch from carrier-based aircraft, the missile programme was cancelled before flight testing began, and the missiles produced were utilized as test vehicles.
The AAM-N-5 Meteor was an early American air-to-air missile, developed by the Massachusetts Institute of Technology and Bell Aircraft for the United States Navy. Initially, both air-launched and ship-launched versions were considered. Versions designed for launch from carrier-based aircraft proceeded to the flight testing stage before the project was cancelled.
SAM-N-8 Zeus, also known as Zeus I, was a project by the Naval Ordnance Laboratory of the United States Navy to develop a guided anti-aircraft artillery shell for launch from 8-inch (200 mm) guns. Tested in the late 1940s, it was overtaken by advances in guided missile technology.
