The Douglas B-18 Bolo is an American twin-engined medium bomber which served with the United States Army Air Corps and the Royal Canadian Air Force (as the Digby) during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2 as a replacement for the Martin B-10.

Though equipped with inadequate defensive armament and underpowered, the Bolo remained the Air Corps' primary bomber into 1941, and the Japanese destroyed some B-18s during the surprise attacks on Dec. 7. By early 1942, improved bombers like the B-17 replaced the Bolo as first-line bombardment aircraft.

The Douglas B-18 Bolo was an American medium bomber used by the United States Army Air Corps (USAAC) during the late 1930s and early 1940s. It was primarily employed for coastal defense and anti-submarine patrols before and during World War II.

In Pearl Harbour, many were destroyed on the ground, without a chance to fight back against the Japanese bombers. It was introduced in Update 1.59 "Flaming Arrows". This is the first multi-engine land-based bomber available in the American Bomber tech tree.

It was designed for a USAAC competition, announced on August 6, 1934, to find a modern replacement for the assorted twin-engine Keystone biplane and Martin B-10 bombers. The DB-1 competed against the Martin 146 and Boeing Model 299 (B-17 Flying Fortress) and beat out the competition after the Boeing 299 prototype crashed during the trials.

The Douglas B-18 was designed to meet a 1934 requirement of the USAAC. This called for a bomber with a range of 2000 miles carrying a ton of bombs, at a speed of at least 200 mph. The Douglas DB-1 design competed with the Martin 146, a modernised B-10, and the Boeing 299, the later B-17. The B-18 was the cheaper and more conservative solution.
