ASR-10
Airplanes played an important role in the second world war. Britain being an island meant long flights over water and air-sea rescue became essential as airmen sometimes had to ditch their planes in the cold North Sea.
Rescue services were usually operated from the coast and Britain copied a German idea of covered barges moored out at sea which were fitted with food, clothing, first aid kit, radio equipment, heaters and bunks. They were code-named 'Cuckoo' and their identifying number was ASR.
ASR-10 was brought to the Clyde area for gunnery practice after the war but is now safely part of the Maritime Museum at Irvine.
