The Martin MB-1 was an American large biplane bomber designed and built by the Glenn L. Martin Company for the United States Army Air Service in 1918. It was the first purpose-built bomber produced by the United States.

In 1921 Martin produced its KG.1 variant of the MB-1, with ten purchased by the Navy as torpedo bombers under the designation MBT. After two were purchased, the designation was changed to Martin MT.

  2. ^ Confusion over Air Service serial numbers has led to figures sometimes seen of 22 or more. However six were built on the first contract, and a later four built in 1919 before the end of the war cancelled all remaining ordered. Ten more were produced for the USN/USMC.
