China, as the third-largest shipbuilder in the world, most ships it builds are equipped with navigation radars of Decca origin (either license-produced or directly imported).
[citation needed] In 1959 Racal Decca, as the company was known then, launched a number of social and sports clubs.
The BridgeMaster II series followed, with a Motorola 68000 CPU and software options like vector traces showing the trajectories of other ships as part of the automatic radar plotting aid package.
The Sperry section of Litton Marine Systems, based in Charlottesville, Virginia, was already producing its own line of marine radars, the Rascar, at the time of the acquisition but this was replaced by the BridgeMaster E. The Rascar had been the American-made radar used in the American Navy and Coast Guard but eventually the BridgeMaster E made inroads there as well.
Northrop Grumman acquired Litton Industries in 2000 and this eventually heralded, in 2004, the end of the use of the Decca name on radars after a period of more than 50 years.
