Sea Cat

Seacat was a British short-range surface-to-air missile system intended to replace the ubiquitous Bofors 40 mm gun aboard warships of all sizes. It was the world's first operational shipboard point-defence missile system and was designed so that the Bofors guns could be replaced with minimum modification to the recipient vessel and (originally) using existing fire-control systems. A mobile land-based version of the system was known as Tigercat.

History

Seacat was designed by Short Brothers of Belfast for use against fast jet aircraft that were proving to be too difficult for the WWII-era Bofors guns to successfully intercept. The missile was based on the Shorts Green Light prototype, itself a development of the SX-A5, a research missile based on the Australian Malkara anti-tank missile to test radio manual guidance of a short-range surface-to-air missile. It replaced the Orange Nell development programme for a lighter weapon than the enormous Sea Slug missile. The first public reference to the name Seacat was April 1958, when Shorts was awarded a contract to develop a close-in short-range air-to-air missile. The missile was shown for the first time to the general public at the 1959 Farnborough Air Show. The first acceptance trials of the Seacat on a warship was in 1961 aboard HMS Decoy. The Seacat became the first operational guided missile to be fired by a warship of the Royal Navy. Later it was adopted by the Swedish Navy, making it the first British guided missile to be fired by a foreign navy.
