The Sea Dart was re-designated the YF-7A, but the type did not reach operational service. This is the real 135763. The one on display at the Florida Air Museum, painted with the same serial until at least 2010, is in fact 135765. By 2013 that error had been corrected.

The second of four Sea Darts to be completed and the last of the two which flew in 1953/54. Single-seat delta-wing Jet-powered Flying boat fighter taking off and landing on twin hydroskis. Retired in 1957 and planned production of other examples was cancelled.
