Here's what you need for an anti-sub aircraft, a Short Admiralty 184 torpedo bomber.
"The Short 184 was the first seaplane to be employed successfully in a naval engagement, and an official letter written to Messrs Short Bros with regard to the work performed by a Short 184 in spotting enemy ships during the Battle of Jutland in May 1916 stated: ' . . . the flight made by Flight Lieut Rutland, with Assistant Paymaster Trewin, as observer, which Sir David Beatty praises so highly, was carried out on a 225hp Short Seaplane.' A Short 184 had previously become the first aeroplane to sink a ship with a torpedo.
First entering service with the RNAS in early 1915, the Short 184 had a long and highly successful career and remained fully active until the Armistice - more than 900 being completed. Its initial power plant of a 167kW Sunbeam gave rise to the often quoted incorrect designation Short 225; several different engines were fitted during the production run. A number of Short 184s were taken on charge post-war by other countries. "
