The VB-3 Razon was a high-angle freefall guided bomb developed by the United States Army Air Force during the 1940s.

Mating the guidance system of the earlier Razon radio-controlled weapon with a British Tallboy 12,000-pound (5,400 kg) bomb, the ASM-A-1 saw brief operational service in the Korean War before being withdrawn from service in 1951.

The VB-3 Razon (for range and azimuth) was a standard 1,000-pound general purpose bomb fitted with flight control surfaces. Development of the Razon began in 1942, but it did not see use during World War II.19th Bomb Group B-29s dropped 489 Razons during,

The Air Force used two guided bombs in Korea, the VB-3 Razon and VB-13 Tarzon, primarily against bridges. After these weapons were dropped from the aircraft, the bombardier visually guided the bomb to the target by radio control.

The Air Force used two guided bombs in Korea, the VB-3 Razon and VB-13 Tarzon, primarily against bridges. The Razon and Tarzon worked using the same method. A bombardier dropped and visually guided the weapon by radio control.

The VB-3 is a guided bomb similar to the VB-1, with the major difference that its flight may be controlled in range as well as in azimuth, and is known generally as the “Razon” bomb.

The VB-5 was a 450 kg (1000 lb) bomb, which used the same tandem octagonal control shroud arrangement as the VB-3/VB-4 Razon. However, the VB-5 was not command guided but used an autonomous light contrast seeker.

The 1,000-pound Razon bomb was a remotely controlled, radio-guided bomb originally developed for use in World War II. Despite some early problems, B-29 bombardiers managed to destroy 15 bridges...
