MASON was regunned in 1950

Hong Kong

MASON was regunned in 1950. (I believe that this was accomplished in the San Francisco Naval Shipyard - probably Hunter's Point.) Her former AA battery of 40 mm and 20 mm guns was removed, and she was re-equipped with rapid-fire 3"/50 mounts, and both Mk 56 and Mk 63 GFCS. The Mk 56 director was mounted centerline, aft of #2 stack, and was the primary means of fire control for the entire 3"/50 battery. The Mk 63 systems (port and starboard) were mounted just aft of the bridge, and were secondary methods for control of the 3"/50's. It was my understanding that MASON was the first Pacific Fleet DD to be converted to the 3"/50 battery and Mk 56 GFCS.) The original depth charge launchers were removed, leaving us with the stern tracks; Hedgehog launchers were installed abaft Mt 52, just forward of the forward fueling station on the 01 level. MASON retained all three 5"/38 twin mounts. They were controlled by the Mk 37 GFCS, although the Mk 56 GFCS could also control them. Before I left,  in early 1957 we had two Mk 38 ASW torpedo launchers installed, port and starboard, just forward of the amidships passageway, up close to the deckhouse, on the main deck.
