The success of the Shorts Seacat system stemmed from a track record of accuracy, low-cost production and ease of operation. The Shorts Tigercat point defence anti-air missile system was a private development of the Seacat and was tested officially and brought into service by the RAF Regiment on 16th November 1967 with No.48 Sqn being re-equipped with 12 launcher units. No.48 Squadron retained the Tigercat missile until 1978 when the RAF Regiment adopted the Rapier missile.
The system is divided between two trailers towed by Land Rovers. One for the missile launcher and one for the optical sight and control gear. The control gear affords the operator Control Line Of Sight adjustment for the missile once it has been launched. An enhanced version of this system utilised radar for blind dark-firing capability.
The Tigercat missile itself is subsonic and powered by a two stage solid fuel motor: it is steered in flight by 4 swept wings, the adjustment of which are controlled remotely by radio from the operator who would have line of sight of both the missile and the target.
