VS-31

Sea Control Squadron 31 (VS-31), known as the "Topcats," was a U.S. Navy anti-submarine warfare squadron established in 1948. Originally flying the Grumman TBM Avenger, the squadron later operated the S-2 Tracker and, most notably, the S-3 Viking. VS-31 served with distinction in both the Atlantic and Mediterranean, conducting carrier-based anti-submarine and sea control missions aboard various aircraft carriers. The squadron was deactivated in 2008, concluding over six decades of operational service.
