The Martin NBS-1 was a military aircraft of the United States Army Air Service and its successor, the Army Air Corps. An improved version of the Martin MB-1, a scout-bomber built during the final months of World War I, the NBS-1 was ordered under the designation MB-2 and is often referred to as such. The designation NBS-1, standing for "Night Bomber-Short Range", was adopted by the Air Service after the first five of the Martin bombers were delivered.
The NBS-1 became the standard frontline bomber of the Air Service in 1920 and remained so until its replacement in 1928–1929 by the Keystone Aircraft series of bombers. The basic MB-2 design was also the standard against which prospective U.S. Army bombers were judged until the production of the Martin B-10 in 1933.
