The first production Sea Venom FAW.20 flew in March 1953 and entered FAA service in 1954. Similar to the Venom NF.2A it featured the Ghost 103 engine, AI.10 radar and a clear-view canopy which was modified to allow it to be jettisoned underwater but no powered control surfaces. In total 52 FAW.20s were built by de Havilland.
