RB 27 Falcon

 

The air-to-air missile RB 27 was acquired for the Swedish Air Force for combatting high speed bomber aircraft at high altitudes.  It was effective at far distances, during nighttime, and under all weather conditions.

 

The RB 27 missile was equipped with a radar echo reflecting passive (semi-active) homing device, which was adapted to the carrier aircraft’s own sight radar PS-01/011. The missile homer and the flight control system would direct the missile on a collision course towards an estimated point of impact, and they would continuously correct the missile trajectory with regard to the velocity, bearing, and altitude changes of the target. Normally, the missile was launched by one of the aircraft radar sights S-7B3/31 and calculated for a direct attack (DA) along with a feasible subsequent lead pursuit (LP), also called a double attack. The homer required radar irradiation of the target from the aircraft radar sight, or it required being guided by interference signals picked up from the target. The missile was aerodynamically controlled by wing rudders, and it was adjusted in all flight positions by a control unit. The missile avionics consisted of miniature components, and vacuum tubes of the sub-miniature type were used. The power sources came from an adapted electric power supply on the carrying aircraft and an onboard fast energizing battery and hydraulic system. Prior to the launch, the missile had to be activated in steps governed by the sight. The steps selected the missile and power supply, and also when and how the homer would be slaved to the aircraft radar frequency, and distance measurement, and the aiming direction of the radar antenna.

 

The missile was propelled by a one stage powder rocket motor. The warhead consisted of an explosive charge, arranged in a ziz-zag link pattern. The warhead was initiated by an active radar proximity fuse or by impact contacts. The missile was mounted on the Missile Pylon F 5, through which cables and connectors transferred avionic data to the missile homer avionics before the firing,

 

The RB 27 was manufactured in Sweden by Bofors, SAAB, and LM Ericsson.  Deliveries to the Swedish Air Force began in 1965.
