The Boeing XP3B-1 (company designation Model 466) was a proposed patrol aircraft, developed by Boeing for use by the United States Navy in the late 1940s. It was planned to be powered by two Allison T40 turboprops driving contra-rotating propellers, and utilized tandem landing gear. The project was cancelled before any aircraft were built.
