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. Like the VB-1, it has special tail unit fitted to a 1,000 pound GP body, and is normally released from high altitude by use of a conventional bomb sight, the guided action being relatively small, so that the trajectory at the time of impact is essentially vertical.
As in the VB-1, flares are employed to assist the bombardier in the visual control of the flight of the bomb. Currently used flares are the T6E1 (white), T7E1 (red), and T8E1 (green). They are of 1,000,000 candlepower, electrically ignited three to four seconds after release, and with one to two minutes of burning time. Mechanically activated flares - T21, T22, and T23 - are under development.
No information about functioning.
