RB 07 Seacat


The missile RB 07 Sea Cat was a watercraft carried ground-to-air missile with a short range used for self-defense against attacking aircraft. The ground-to-air missile system was installed on Destroyers of the Östergötland-class, after the anti-aircraft gun was removed and replaced by mounts for the missile RB 07. The Destroyers were equipped with 12 stored missiles plus 4 units in the mount. The missiles were radio controlled and flew at sub-sonic speed.


The RB 07 Seacat ground-to-air missile systems were manufactured in England and were introduced on Swedish Destroyers in 1963.

When an attacking aircraft enters the target range of the missile, the missile system is activated. Each mount is charged with four missiles. The missile is fired and governed by two operators. After receiving the target location the first operator aims the sight on the target, and the mount is remotely controlled by the sight. At a suitable moment he will launch the missile. The second operator guides the missile towards the target and into the aiming line by radio command signals, using a joystick and a binocular. The guidance is assisted by the missile tracer smoke.


With a new system, developed in Sweden, the binocular follows the target either by using a simple optical alignment or by using radar. With the latter system the sight is radar controlled and it remotely aims the mount from the fire control of the light artillery guns, which allows an almost simultaneously firing or firing by turns with missiles and gun fire. The warhead is triggered by an IR proximity fuse or a direct hit.


Later on an improved version, The Seacat Mk 1 Mod 1, was developed by introducing a pressure wave creating warhead with an increased weight and with a higher efficiency. The weight of the electronic components was decreased, so the total weight of the missile was unchanged.
