Martin MB-1


Martin MB-1 History
In 1916 the United States Army Air Service (USAAS) requested an American built heavy bomber to equal of exceed the performance of the new British Handley Page O WW1 heavy bomber in service with the British RFC, Glenn L. Martin responded to this urgent request with the twin engine Martin MB-1 biplane strategic heavy bomber. By the time the Martin MB-1 aircraft was ready to go into production in September 1918, WWI was clearly drawing to a close and the design proved better than the type O bomber but not as good as the other new bombers like the Vickers Vimy.

With WW1 nearly over most the outstanding Martin MB-1 orders were cancelled by the US government, with only the first twenty Martin MB-1 bombers being actually produced, none of the Martin MB-1 bombers built arrived in Europe in time to be used during WWI.

Only a single surviving Martin MB-1 biplane bomber remains in existence today out of the twenty produced, it can be found on display in the excellent USAF museum.
