In 1951, the U.S. Navy asked America’s top aerospace companies to submit proposals for a turboprop-driven VTOL fighter plane that could provide protection for troop and transport ships at sea. Martin Aircraft was one of several companies to develop innovative vertical-launch concepts for this competition. It looked at a number of solutions, including this “C” version in which two counter-rotating propellers were mounted close to the airplane’s tail.
This model shows how the Martin 262c would had been if it had been selected by the Blue Angels. It includes the tail numbers 1 through 4 in case you want to do the full flight.
