The Martin B-10 was an advanced aircraft for its time, but made obsolete when World War 2 had arrived.

The Martin B-10 medium bomber was a breakthrough design for American military aviation when it appeared on the scene in 1932. Though made obsolete at the outbreak of hostilities in World War Two, the type persevered in other forms thanks to export customers. In the end, over 300 examples of the type would be produced that would cover the B-10 and the marginally improved B-10 in the form of the B-12.

Once in production and reaching operational status, the B-10 became the first American designed and bomber made of all-metal construction practices and produced in any quantity. The system was also the first design for the Americans to feature armament that was fitted to turrets for increased defensive performance against enemy fighters. In any case, the B-10 held many evolutionary breakthroughs in the field of military aviation for the United States - practices and design lessons that would sure play a role in future bomber needs just years later.

The Martin B-10 was a twin engine medium-class bomber fitted with Wright-brand R-1820 G-102 Cyclone 9-cylinder radial piston engines. The engines were fitted on what would become the USAAC's first attempt at a cantilever low-wing monoplane design. The crew of four were placed about in windowed positions which consisted primarily of the nose compartment, the cockpit and a mid-to-rear glazed area. Armament was strictly defensive and consisted of a single 7.62mm machine gun in the nose, a single 7.62mm machine in a dorsal position and still another single 7.62mm machine gun in a ventral position. Maximum bombload was limited to 2,260 pounds of internal ordnance.

Export customers kept the B-10 production lines moving along well after the United States Army Air Corp had removed the type from its service. Primary customers included the Netherlands with an order of 120, Argentina with 35 and Thailand and Turkey with 26 and 20 respectively. Though outclassed in a few short years, the B-10 was nonetheless a design worth noting as it effectively did away with any future aircraft designs not of all-metal construction.

Glenn Martin won the prestigious Collier Trophy in 1932 for his design work on the Martin B-10.
