RB 302 at Arboga Robotmuseum


Early in 1947, parallel to the 301- program, the 302/303 concept was initiated with an entirely new configuration.


A cylindrical body, a pointed nose section, a thin wing profile and a powder rocket motor


For the 303 project a special test missile 302 in scale 1 : 1.25 was developed. It was intended to be dropped from an aircraft, approaching at a low altitude over the water and diving for an underwater hit below the side armor of the target. This ambition can be found in the proposal of the Commander-in-Chief of Air Force to the Supreme Commander of the Armed Forces already in October 1945.


The design work started in 1947. The first firing of a missile with automatic steering and altitude control was carried out at RFK Karlsborg in 1948, and was fired from a catapult. In March 1948 a new and very stable, 197 feet long, horizontal railway track was tested, capable of carrying heavy missiles with able-bodied booster rockets and high firing velocities, the same as for the RB 3023 and future missiles.


Beginning in early summer 1948 the missile RB 302 was fired at a rate of 2 missiles per month. The RB 302 was also dropped from a/c T 18.

35 missile RB 302 were manufactured.

The tests were terminated in 1955.

An RB 302 specimen exists in our museum.
