|36k|| Heavy gun batteries were of somewhat limited value because they lacked fire controls. The next step then, was to add a surface-ship type fire control system: an Mk 6 stable element, and an Mk 6 computer driving gun-order repeaters at the guns. The most striking change was internal: a gun plot was installed in the forward crew quarters. In the autumn 1949, it was decided to have a number of experimental changes made to the ship during her forthcoming overhaul, and she was redesignated AGSS-399 on 30 September. On 7 November, she arrived at the Philadelphia Naval Shipyard where the work was done. The modifications and repairs were completed on 11 March 1950. A picture of navsource explains what was done: installation of a surface-ship type fire control system: an Mk 6 stable element, and an Mk 6 computer driving gun-order repeaters at the guns. The most striking change was internal: a gun plot was installed in the forward crew quarters. Sea Cat (SS-399), shown here, was the prototype. She also had a pair of single 40 mm guns.
The cylindrical object on her foreback is a dome covering her new WFA "integrated" sonar, which (in theory) would replace both the older WCA & JT In fact, JT was retained because its long line array gave more precise bearings than the small array inside the radome.
Note too that the usual wartime SD air warning radar had been replaced by the big antenna of the late war SV, on the auxillary mast abaft the periscope shears and conning tower. Six other boats (SS-229, 340, 401, 406-8) were also converted to "gunboats".
The Sea Cat is shown here off Balboa, Canal Zone, on 9 March 1949.
