The Glenn L. Martin Company made several models of bombers for the U.S. military, including the B-10, B-12, and JRM Mars. The B-10, which went into service in 1934, was noted for its innovations such as rotating gun turrets, enclosed cockpit, and retractable landing gear. Some B-12s were converted into seaplanes for coastal patrol The JRM Mars was a type of "flying boat" bomber built for the U.S. Navy that was modified and used as a transport plane during World War II. Pilot Glenn L. Martin started his first aircraft company in 1912. It merged with the Wright Company in 1916, but Martin left and formed another company in 1917. It later merged with American-Marietta in 1961 and with Lockheed Corporation in 1995. It is now part of Lockheed-Martin, an aerospace and defense contractor.
