No complete Cuckoo airframe survives, although Mark I wings can be seen at the National Museum of Flight in Scotland. The Japanese naval attaché sought details while the Royal Navy and Sopwith were still defining the aircraft. Japan was therefore following the programme before the Cuckoo had demonstrated an operational capability. The Imperial Japanese Naval Air Service later acquired six Viper-powered Mark II machines. The surviving fragments show what remains physically, while the Japanese service history traces how British carrier-aircraft ideas travelled internationally.

No intact Cuckoo survives, while preserved Mark I wings and Japan's operation of six Mark IIs trace the aircraft's material and international afterlife.
