The Gorgon missile family was a series of experimental air-to-air, air-to-surface, and surface-to-surface missiles developed by the United States Navy's Naval Aircraft Modification Unit between 1943 and 1953. The immaturity of the technology involved meant that none of the Gorgon missiles achieved operational service, however they were extensively used in the development of guided missile controls and guidance technologies.
The LBD-1 Gargoyle was an American air-to-surface missile developed during World War II by McDonnell Aircraft for the United States Navy. One of the precursors of modern anti-ship missiles, it was extensively used as a test vehicle during the late 1940s.
The JB-4, also known as MX-607, was an early American air-to-surface missile developed by the United States Army Air Forces during World War II. Using television/radio-command guidance, the JB-4 reached the flight-testing stage before being cancelled at the end of the war.
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-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.
The VB-3 Razon was a high-angle freefall guided bomb developed by the United States Army Air Force during the 1940s. Razon was a standard AN-M65 1,000-pound general-purpose bomb, the same basic ordnance unit used for its AZimuth-ONly guided predecessor, the VB-1 Azon guided ordnance, with the Razon concept fitted with flight control surfaces that also enabled adjustment in the vertical plane, like the Luftwaffe's heavier Fritz X armored anti-ship guided ordnance. Development of the Razon began in 1942, but it did not see use during World War II although it was combat ready in the summer of 1945. The VB-4 used a 2,000-pound bomb.
The Naval Aircraft Modification Unit KDN Gorgon, originally designated TD2N, is an early jet-powered target drone developed by the Bureau of Aeronautics and constructed by the Naval Aircraft Modification Unit for use by the United States Navy. First flown near the end of World War II, it was cancelled due to problems with its engine in 1946.
The PTV-N-2 Gorgon IV was a subsonic ramjet-powered missile developed by the Glenn L. Martin Company for the United States Navy. Originally intended as an air-to-surface weapon, it materialized as a propulsion test vehicle, and between 1947 and 1950 was used for test purposes and, as the KDM Plover, as a target drone.
The CTV-N-2 Gorgon IIC – also designated KGN, KUN, and CTV-2 – was an experimental drone, originally intended as a surface-to-surface missile, developed by the United States Navy near the end of World War II. It was used to test control and homing systems for guided missiles, and was also produced in small numbers as a target drone under the designations TD3N and KD2N.
The KA2N Gorgon IIA – also designated KU2N, CTV-4, and CTV-N-4 – was an air-to-air missile developed by the United States Navy near the end of World War II. Proving a failure in its designed role, it was repurposed as an experimental testbed for missile technology.
The Gorgon III – given the military designations KA3N, KU3N, CTV-N-6 and RTV-N-4 – was a rocket-powered air-to-air missile developed by the United States Navy near the end of World War II. With the end of the war, the program was changed to that of a research vehicle for missile control systems; both single and twin-rocket-powered versions were built and tested.
The XSSM-A-23 Dart was an anti-tank-guided missile developed for the United States Army in the 1950s. After protracted development, the missile, similar in design to the French SS.10, was cancelled in favor of purchasing the SS.11 missile.
The Republic SD-3 Snooper was an early reconnaissance drone developed by Republic Aviation for the United States Army. It was evaluated by the Army Signal Corps in 1959, but did not enter operational service.
The Republic SD-4 Swallow was an early high-speed reconnaissance drone developed by Republic Aviation for the United States Army. Intended for use by the U.S. Army Signal Corps to target tactical ballistic missiles, it was cancelled before the first prototype could be completed, and did not see operational service.
The Fairchild SD-5 Osprey was an early high-speed reconnaissance drone developed by Fairchild Aircraft for the United States Army. Intended for use by the U.S. Army Signal Corps to gather targeting information for tactical ballistic missiles, it was cancelled before the first prototype could be completed, and did not see operational service.
The ASM-N-6 Omar was a short-range air-to-surface missile developed for and evaluated by the United States Navy in the early 1950s. Intended to use existing unguided rockets as a basis and using a novel guidance system involving optical beam-riding, the program was unable to resolve difficulties with the guidance system and was cancelled without entering service.
The TDU-12/B Skydart was an unguided target rocket built by Curtiss-Wright for use by the United States Air Force. It was used operationally from the late 1950s to the mid-1960s.
The AUM-N-4 Diver, also known as Kingfisher D and AUM-4, was a proposed anti-ship and anti-submarine missile, developed for use by the United States Navy in the late 1940s. It was intended to carry a rocket-propelled torpedo that used a single rocket motor for both airborne and underwater propulsion; due to technical issues encountered in the development of the torpedo, no missiles were built before the program was cancelled.
The AUM-N-6 Puffin, also known as Kingfisher F and AUM-6, was an anti-ship and anti-submarine missile developed for use by the United States Navy in the late 1940s. Pulsejet-powered and intended to allow an aircraft to launch a torpedo or bomb from stand-off range, it was flight-tested but failed to enter operational service.
The SUM-N-2 Grebe, also known as Kingfisher E and SUM-2, was a rocket- and pulsejet-powered anti-ship and anti-submarine missile developed by the United States Navy in the late 1940s. Intended to allow a ship to deliver a torpedo at a significant distance from the launch location, it proved impractical in trials, and did not enter operational service.
