1. Grumman S-2D Tracker Marker
A New Approach to Anti-Submarine Warfare Nicknamed "Stoof" (a rough pronunciation of its designation), the S2F (later re-designated S-2), was the first carrier-based aircraft able to both search for an attack submarines. Previously, the two roles had been performed by separate aircraft. S-2s were equipped with multiple sensors, including a search radar, sonobuoys (deployed from the engine housing), a magnetic anomaly detector (housed in a retractable tail boom), and a searchlight. An internal weapons bay accommodated torpedoes, mines, and depth bomb. The Tracker's S-2D version, like the one before you, featured a longer and wider fuselage, larger wings and tail surfaces, and longer engine housings to accommodate additional sonobuoys. The Tracker's robust design became the basis of an Airborne Early Waring (AEW) aircraft (the E-1B Tracer) and a Carrier Onboard Delivery (COD) aircraft (the C-1A Trader). The last S-2 squadron was disestablished in August 1976.

Our Display Aircraft S2F Bureau Number 149240 was manufactured on 20 March 1962, and flew at NAS Patuxent River with the Naval Research Laboratory's Flight
