General play style

This is the first multi-engine land plane bomber available in the American Bomber tech tree. With a maximum bomb load of 2000 lbs, it is a decent medium bomber, although its gunner's field of fire are somewhat poor, the only viable one being the dorsal turret gunner which suffers for the large blind spot the rudder creates directly behind the aircraft. It is recommended to level bomb at high altitude, as its poor maneuverability means you will have a hard time bombing moving ground targets at low altitude without a relatively straight bombing run.

Vehicle characteristics

As the first non-naval bomber available to the Americans, this plane is faster than its predecessors in the tech tree, the PBY flying boats. It's bomb load isn't half bad for tier 1, with it's maximum bomb load being a single 2000 lb bomb, which is enough to destroy a base in one strike in RB as of 1.77. The defensive armament is somewhat lackluster however, with only 3 defensive positions, and of the 3 only one is somewhat viable for the defense of the aircraft. The lower ventral gunner is almost useless, and easily taken out, and the frontal gunner is only useful if your current enemy is directly in front and below you. The last turret, and massive dorsal contraption, can only fire in a 180 degree arc rear of the aircraft, and a significant bind spot is formed by the turrets proximity to the rather large rudder. Overall this bomber can be considered a trainer for the later American heavy bombers with it's slow lumbering presence and high bomb load, coupled with multiple defensive positions.

Pros and cons

Pros

  • Can be very sturdy in AB. 20mm cannons are a danger, but that's the same for all planes
  • Single 2000lb bomb can level entire areas, decimate vehicle formations, and be of great use in custom battles.
  • As of recent, the frontal gunner has a much more open field of fire allowing some flexibility in engaging other bombers.
  • As mentioned, it is fairly fast for its tier and class, meaning you can outrun most biplanes, russian I-153s being an exception.
  • Similar playstyle to the B-10, so any players new to the Bolo that have used the B-10 can expect the same general performance.
  • Oddly, for an American bomber, the hull isn't packed with objects, leading to free space.

Cons

  • As all American bombers are, it is a very large plane and can be a fairly easy target without an escort.
  • Although the FoF is decent, the .30cal MG's cant compete with its Russian or German peers that have a fire rate advantage.
  • The engines are fairly easy to target with centerlined weaponry. This leads to the Yak-1 and LaGG series being very deadly to a B-18
  • It has gained a notoriety for its bombload, meaning you a team wide target.
  • When doing a loop, it commonly overshoots the cursor, leading to a loss (or gain) of speed.

History of creation and combat usage

The B-18 Bolo was designed because the US Army wanted a new bomber that was faster and carried a heavier bomb load than the existing Martin B-10.

Two competitors showed up. Boeing model 299 (B-17), and the Douglas DB-1. Although the Boeing design was clearly superior (heavier bombload, longer range, and better defensive armament) The Boeing model 299 crashed upon takeoff, and the Army immediately switched to the Douglas model. The lower price also counted in favour of the B-18 ($58,000 compared to $99,260). The B-18 played a stop-gap role until better bombers (B-17 and B-24) to replace it. The B-18 was not very widely used due to the lack of defensive armament and speed. Only 350 B-18s were built until production stopped and the plane declared obsolete.
