== Description ==

[[File:GarageImage_PBM-3 Mariner.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} USA bomber {{Battle-rating}}. It was introduced during [[Update 1.85 "Supersonic"]] as part of the [https://warthunder.com/en/news/6037-event-sea-voyage-en Sea Voyage] event that ran from 21 February to 11 March 2019.

== General info ==
=== Flight Performance ===
Due to the fact that it is a large seaplane, it is not very manoeuvrable and has trouble banking. However, when you get into a high-angle bank, it does turn fairly easily because of its large wings. As for payloads, it doesn't matter which payload you take because all of the bombs are contained in the nacelle-mounted bomb bays and won't have a big difference in performance.

=== Suspended armament ===

{{main|AN-M30A1 (100 lb)|AN-M64A1 (500 lb)|AN-M65A1 (1,000 lb)}}
The '''''{{PAGENAME}}''''' is able to be equipped with:

* 12 x 100 lb AN-M30A1 bombs
* 8 x 500 lb AN-M64A1 bombs
* 8 x 1000 lb AN-M65A1 bombs

=== Defensive armament ===

{{main|Browning M2 (12.7 mm)}}

The '''''{{PAGENAME}}''''' is defended with:

* 1 x 12.7 mm M2 Browning machine gun, nose turret (400 rpg)
* 1 x 12.7 mm M2 Browning machine gun, 2 x waist turret (375 rpg = 750 total)
* 1 x 12.7 mm M2 Browning machine gun, dorsal turret (600 rpg)
* 1 x 12.7 mm M2 Browning machine gun, tail turret (350 rpg)

== Usage in battles ==
In RB, it should be used as a traditional heavy bomber. You will need an escort so try and play with a squadmate or ask for one in the chat. You will be able to destroy at least two bases with your large bombload, in an uptier it will take 4x 1000lbs to destroy a base and in a downtier it will take 3x 1000lbs. Try and stay away from enemy fighters and near friendlies whenever possible as you defensivr turrets will have trouble against many aircraft that you face.

== History ==

In the mid 1930s, the U.S. Navy was eager to replace their outdated flying boats with newer models. In order to do so, the Navy started a competition between aircraft manufacturers, whose winner would receive a production contract with the Navy.The Martin company submitted the designs on their four-engine Model 160 aircraft, which didn’t garner any significant interest from the Navy. However, Martin continued to work on the design, reworking it into a two-engine aircraft, designated Model 162.This design proved to be a lot more successful, with the Navy quickly ordering for a prototype of the aircraft to be produced. Designated XPBM-1 “Mariner”, the prototype conducted its maiden flight in February 1939. Following successful trials, the aircraft was adopted by the USN as early as September 1939 and ordered into production in late 1940, Martin received a large order for more flying boats to be manufactured. However, with the company’s production capacity being reached, construction of these new machines was delayed. In the meantime, the PBM was further improved by installing new engines, increasing overall size and doubling payload capacity. The new PBM-3 Mariner entered production in 1941, the first batch of 32 vehicles entering service in 1942.The Mariners primarily served with the USN as coastal patrol aircraft before the outbreak of WW2. However, after the United States’ entry into WW2, Mariners were used in the anti-submarine role in the Atlantic and also took part in operations in the Pacific Theatre.The PBM-3 Mariner flying boats of the third series served very briefly during WW2, as nearly all PBM-3s from the first series were converted into unarmed transport machines, shortly after their construction. Nevertheless, the aircraft proved to be very successful and further models were built in large numbers - in total more than 1360 Mariner vehicles of different modifications. Mariners were also used in small numbers by Great Britain, Australia, Argentina, Uruguay and the Netherlands. The last Mariners were phased out of service during the 1960s, being replaced by newer aircraft.

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} American bomber {{Battle-rating}}. 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.

== General info ==
=== Flight Performance ===
''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.''

=== Defensive armament ===

{{main|Browning (7.62 mm)}}

The '''''{{PAGENAME}}''''' 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 1.91). The defensive armament is somewhat lackluster 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.
* Has a low BR, meaning that it fights fairly weak enemy fighters.

'''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.

B-18A

U62866787: /* Usage in battles */

{{Specs-Card|code=b_18a}}

== Description ==

[[File:GarageImage_{{PAGENAME}}.jpg|420px|thumb|left]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} American bomber {{Battle-rating}}. 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.

== General info ==
=== Flight Performance ===
''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.''
