Douglas AD-4 Skyraider

Last revised October 18, 2001


The AD-4 version was built in larger numbers than any other Skyraider variant. The AD-4 differed from earlier Skyraider variants in being powered by an improved engine, the 2700 hp R-3350-26WA. It had an improved windshield with better bulletproof protection, a P-1 automatic pilot, and a modified arrester hook. A pitot tube was added at the top of the leading edge of the the vertical tail.
