Description

GarageImage B-18A.jpg


The B-18A is a rank I American bomber with a battle rating of 2.0 (AB) and 1.7 (RB/SB). 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. With a maximum bomb load of 2000 lbs, it is a decent medium bomber, although its gunners' fields of fire are somewhat poor, the only viable one being the dorsal turret gunner which suffers from the large blind spot the rudder creates directly behind the aircraft. It is recommended to level bomb at high altitude, as its poor manoeuvrability means you will have a hard time bombing moving ground targets at low altitude without a relatively straight bombing run.

Survivability and armour

  • No armour
  • Engines and fuel tanks in root of wing

Armaments

Suspended armament

The B-18A can be outfitted with the following ordnance:

  • 12 x 100 lb AN-M30A1 bombs (1,200 lb total)
  • 8 x 250 lb AN-M57 bombs (2,000 lb total)
  • 4 x 500 lb AN-M64A1 bombs (2,000 lb total)
  • 2 x 1,000 lb AN-M65A1 bombs (2,000 lb total)
  • 1 x 2,000 lb AN-M66A2 bomb (2,000 lb total)

Defensive armament

Main article: Browning (7.62 mm)

The B-18A is defended by:

  • 1 x 7.62 mm Browning machine gun, chin turret (500 rpg)
  • 1 x 7.62 mm Browning machine gun, dorsal turret (500 rpg)
  • 1 x 7.62 mm Browning machine gun, ventral turret (500 rpg)

Usage in battles

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. Its bomb load isn't bad for tier 1, with its maximum bomb load being a single 2000 lb bomb, which is enough to destroy a base in one strike in RB (as of Update 1.77). The defensive armament is somewhat lacklustre however, with only 3 defensive positions, and of the 3 only one is somewhat viable for the defence 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, a 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 its slow lumbering presence and high bomb load, coupled with multiple defensive positions.

Pros and cons

Pros:

  • Fairly manoeuvrable for a bomber.
  • Single 2000 lb bomb can destroy a entire base, decimate vehicle formations, and be of great use in battles.
  • Frontal gunner has a bigger field of fire allowing some flexibility in engaging other aircraft.
  • 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.

Cons:

  • Rather slow.
  • Weak defensive armament won't help you very well against enemy fighters.
  • Nose machine gun can't fire directly to the front.
  • Very large plane and can be a easy target to shootdown without a fighter escort.
  • Defensive armament: .30cal MGs cannot compete with its Russian or German counterparts, or other nations that have a fire rate advantage.
  • The engines are fairly easy to target and be knocked out with centerlined weaponry. Yak-1 and LaGG series are very deadly to a B-18
  • It has gained a notoriety for its bombload, meaning you are a team wide target.
  • When doing a loop, it commonly overshoots the cursor, leading to a loss (or gain) of speed.

History

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 take-off, 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) were built 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 was declared obsolete.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
