Boeing XPBB-1 Sea Ranger

XPBB-1 Sea Ranger picture
The frequent appearance of German U-Boats close to U.S. coastal waters made the U.S. Navy aware that it needed a long-range maritime patrol aircraft. Because Boeing had considerable experience with flying boats (the most famous being the Boeing 314-A "Clipper" used by Pan Am Airways), the Navy approached Boeing about designing a suitable aircraft for its purposes. In June 1940 a contract was awarded for a prototype XPBB-1, with the first flight taking place in July 1942. Unfortunately for Boeing, changing ideas regarding maritime patrol aircraft brought cancellation of the order for the U.S. Navy's XPBB-1 Sea Rangers, and this excellent flying boat never proceeded beyond the prototype stage. The sole example of the Sea Ranger was unofficially given the name "The Lone Ranger".
