Many of the original patrol aircraft were converted from long-range bombers or airliners, with notable conversions being Germany's Focke-Wulf Condor and the widespread use of B-24 Liberators during World War II to patrol the areas between Iceland and Greenland and attack German submarines. Purpose-built aircraft were also used, including England's Shorts Sunderland and the American-made PBY Catalina.

After the war the patrol role was generally taken over by conversions of civilian airliners that had range and performance better than most WWII bombers. The latest jet-powered bombers of the 1950s did not have the endurance needed for long, over-water cruising, and more importantly did not have the low loitering speed necessary for anti-submarine operations. The main threat to the United States throughout the 1960s and into the 1980s were Soviet submarines, which were found primarily with the use of sonobuoys, and then attacked with homing torpedoes.

Today the threat of a large scale submarine attack is remote, and many forces are downsizing their patrol aircraft fleets. Those still in service are used primarily for counter-smuggling and Exclusive Economic Zone enforcement duties.
