Pratt & Whitney J52 (company JT8A) is a historical axial-flow, twin-spool turbojet family developed for U.S. Navy attack aircraft. Pratt & Whitney identifies the J52 as an out-of-production engine that remains supported through military sustainment; U.S. Navy sources document the 8,500 lb J52-P-6A on the A-4 Skyhawk and twin 11,200 lb J52-P-408 engines on the EA-6B Prowler. Exact P-6/P-8/P-408 variants and aircraft relationships remain separate identities.
