The Martin XB-16, company designation Model 145, was a projected heavy bomber designed in the United States during the 1930s.
|National origin||United States|
|Manufacturer||Glenn L. Martin Company|
|Status||Project only – canceled|
The XB-16 was designed to meet the United States Army Air Corps (USAAC) request for a bomber that could carry 2,500 lb (1,100 kg) of bombs 5,000 mi (8,000 km; 4,300 nmi).
In 1935, Martin revised the XB-16 design as the Model 145B. The wingspan was increased from 140 ft (43 m) to 173 ft (53 m), and a set of V-1710 engines added to the trailing edge. This version had a wingspan 20% greater than that of the B-29 Superfortress, the first operational bomber that would fill the role intended for the XB-16.
The XB-16 was canceled for essentially the same reason that the B-15 project was: it was not fast enough to meet the requirements set by the Army. Since both were canceled around the same time, Martin did not have time to produce an XB-16.

The Boeing XB-15 (Boeing 294) was a United States bomber aircraft designed in 1934 as a test for the United States Army Air Corps (USAAC) to see if it would be possible to build a heavy bomber with a 5,000 mi (8,000 km) range. For a year beginning in mid-1935 it was designated the XBLR-1. When it first flew in 1937, it was the most massive and voluminous aircraft ever built in the US. It set a number of load-to-altitude records for land-based aircraft, including carrying a 31,205 lb (14,154 kg) payload to 8,200 ft (2,500 m) on 30 July 1939.The aircraft's immense size allowed flight engineers to enter the wing through a crawlway and make minor repairs in flight. A 5,000 mi (8,000 km) flight took 33 hours at its 152 mph (245 km/h) cruising speed; the crew was made up of several shifts, and bunks allowed them to sleep when off duty.Boeing Y1B-20
The Boeing Y1B-20 (Boeing 316) was designed as an improvement on the Boeing XB-15 (Y1- indicates a funding source outside normal fiscal year procurement.) It was slightly larger than its predecessor, and was intended to use much more powerful engines. It was presented to the Army in early 1938, and two orders were placed soon after. The order was reversed before construction began.
Despite their cancellation, the XB-15 and Y1B-20 laid the groundwork for the Boeing B-29 Superfortress.Glenn L. Martin Company
The Glenn L. Martin Company was an American aircraft and aerospace manufacturing company founded by aviation pioneer Glenn L. Martin. The Martin Company produced many important aircraft for the defense of the US and allies, especially during World War II and the Cold War. During the 1950s and 60s, the Martin Company moved from the aircraft industry into the guided missile, space exploration, and space utilization industries.
In 1961, the Martin Company merged with American-Marietta Corporation, a large sand and gravel mining company, forming Martin Marietta Corporation. In 1995, Martin Marietta merged with aerospace giant Lockheed to form the Lockheed Martin Corporation.List of cancelled military projects
