HVAR

American air-to-air rocket. High-Velocity Air Rocket. An unguided fighter weapon, it was later adapted for use by NACA in the early 1950's to boost subscale aerodynamic models to supersonic speed.

AKA: Holy Moses. Status: Retired 1957. First Launch: 1945-10-13. Last Launch: 1957-02-15. Number: 32 . Payload: 2.40 kg (5.20 lb). Thrust: 25.00 kN (5,620 lbf). Gross mass: 63 kg (138 lb). Burn time: 0.90 s. Height: 1.83 m (6.00 ft). Diameter: 0.12 m (0.39 ft). Apogee: 10 km (6 mi).

HVAR began with service frustration with original 5-inch version of the FFAR. Development of a larger rocket motor, still using the same 5 inch diameter, resulted in a rocket with a velocity 1530 km-h (950 mph) while delivering a warhead of the same size. First tests began in December 1943. Dubbed Holy Moses, the rocket became operational in July 1944 and was used by both the US Army Air Force and Navy. The GP round was fitted with tail and nose fuses, the armor-piercing round with a nose fuse. After the war versions with shaped-charge anti-tank warheads and proximity fuses were developed. More than one million HVARs were built by the time production ended in 1955.

0 kg (5.20 lb). Maximum range: 1.50 km (0.90 mi). Boost Propulsion: Solid rocket. Maximum speed: 1,610 kph (1,000 mph).

The 5-inch FFAR suffered from insufficient speed because of its small motor. Therefore the development of a larger rocket motor with 5-inch diameter was begun, and the first test firings occurred in December 1943. When fitted with the warhead of the 5-inch FFAR, the rocket achieved a velocity of 1530 km-h (950 mph), making it a very powerful weapon for its time. It was officially designated as 5-Inch HVAR (High-Velocity Aircraft Rocket), but often called Holy Moses. It became operational in July 1944, and was used by Army Air Force and Navy aircraft.

During World War II, two versions of Holy Moses were built, one general-purpose with base and nose fuzes, and one with a semi-armour-piercing warhead and a nose fuze only. Postwar developments added a shaped-charge anti-tank warhead, and a new general purpose type with a proximity fuze. More than one million Holy Moses HVARs were built until production ended in 1955.
