Classic ASW aircraft, a twin engine shoulder wing aircraft. The S-2 was compact and ugly, with a retractable MAD boom and ventral search radar. Launchers for sonobouys were incorporated in the engine nacelles.  The S-2 had a long career, and some are still in service, while others have a second life as fire fighting aircraft --- sometimes re-engined with turboprops. In military service, some were modified to US-2 light transports or RS-2 reconnaissance aircraft. The E-1 Tracker and C-1 Trader were AEW and COD versions of the S-2.

Regarding normal ASW altitudes. Normal sub patrol & search altitude was 500 feet for S2F's. When contact was made they would descend to 50 feet and go on instruments to maintain that altitude especially at night. The lower altitude was to enable the ASQ 8 (MAD equipment) to have maximum search depth while still maintaining a safe flying altitude. -- Hal Neubaurer
