Unfortunately, the larger bomb loads come at the price of being very big and heavy compared to other bombers around its BR. Luckily, the PBM-1 has 5 turrets all housing 12.7 mm machine guns which is excellent for its BR. None of the turrets cover the bottom of the aircraft so players need to take evasive action against aircraft climbing up to attack.

Description
Glenn L. Martin Company was one of the few companies in America that was heavily into designing and producing seaplanes. One of the many seaplanes they built was the twin-engine PBM Mariner intended to be the successor of the P3M. The PBM-1 would feature two Wright R-2600-6 engines each producing 1,600 hp as well as a gull wing type design and twin tail. They entered service in 1940 and were utilized in regular patrols as well as anti-submarine warfare. Ten U-boats were sunk by PBM Mariners including U-158 which was sunk near the Bermudas. Mariners in American service were used until the last squadron (VP-50) retired the aircraft in 1956.
Introduced in Update "Hot Tracks", the PBM-1 "Mariner" is a very well-defended bomber capable of carrying heavy bomb loads. Unfortunately, the larger bomb loads come at the price of being very big and heavy compared to other bombers around its BR. Luckily, the PBM-1 has 5 turrets all housing 12.7 mm machine guns which is excellent for its BR. None of the turrets cover the bottom of the aircraft so players need to take evasive action against aircraft climbing up to attack. The PBM-1 "Mariner" is a strong bomber thanks to its excellent bomb load and strong defensive armament.
General info
Flight performance
The PBM-1 does not shine in flight performance as it has terrible climb rate and speed. This along with the low wing-loading makes it your average medium bomber without the perks of being able to outrun or out-climb your opponent.

Survivability and armour
A robust aircraft and able to take more damage than others of size, compensating for lack of armor and slower speed. It also has .50 cal defensive machine guns covering nearly all angles, best angle is on beam where 3 of the mg's can converge. If one cannot fly above enemy fighters, then fly just above the ground where defensive gunners can engage. A well-timed bomb could also take down a pursuing enemy.

Armaments
Suspended armament
The PBM-1 "Mariner" can be outfitted with the following ordnance:
- 12 x 100 lb AN-M30A1 bombs (1,200 lb total)
- 6 x 250 lb AN-M57 bombs (1,500 lb total)
- 6 x 500 lb AN-M64A1 bombs (3,000 lb total)
- 2 x 1,000 lb AN-M65A1 bombs + 4 x 500 lb AN-M64A1 bombs (4,000 lb total)
- 4 x 1,000 lb AN-M65A1 bombs (4,000 lb total)
- 4 x 1,600 lb AN-Mk 1 bombs (6,400 lb total)
It all about big bombs, and lots of them. The 4 x 1,000 lb AN-M65A1 bombs is ideal, but in some missions carrying 2 x 1,000 lb AN-M65A1 bombs + 4 x 500 lb AN-M64A1 bombs (also 4,000 lb total) can work better.
Defensive armament
The PBM-1 "Mariner" is defended by:
- 1 x 12.7 mm M2 Browning machine gun, nose turret (400 rpg)
- 1 x 12.7 mm M2 Browning machine gun, dorsal turret (400 rpg)
- 1 x 12.7 mm M2 Browning machine gun, 2 x beam turrets (375 rpg)
- 1 x 12.7 mm M2 Browning machine gun, tail turret (350 rpg)
All the guns cover the upper hemisphere of the PBM, best to fly on deck when enemy is near. The M2 Browning machine gun is potent at this battle rating, so you have a good chance of shooting down an aircraft. Remember to select the API-T belt.
Usage in battles
The PBM-1 should be played like its predecessors. Fly high and bomb bases. The PBM is however fairly slow and has a rather bad climb rate, so it will take time. The PBM can carry up to 4 x 1,000 lb bombs. It is advisable to carry this bombload for bombing bases. Even though you are slow, you are not defenseless. Your .50s will shred everything at your BR. Once your bombs are dropped it is advisable to land, but acting as a "gunship" can also be somewhat successful.

Pros and cons
Pros:
- Quite manoeuvrable for a bomber (can outturn many heavy fighters, and some single-engine fighters)
- Can carry a large payload for its BR (4,000 lbs)
- If aimed properly, and using the right belts, defensive armament is very deadly
- Defensive armament has great coverage
- Using WEP doesn't make engines overheat
- Large fuselage with lots of non-critical empty space can absorb lots of bullets
- Self-sealing fuel tanks (4 in lower fuselage, 1 in each wingroot)
Cons:
- No armour
- Gunners can easily be taken out, especially the tail gunner (no armour, and no bulletproof glass either)
- Lacks a belly turret (due to being a boat) and therefore vulnerable to attacks directly from below
- Very slow aircraft with a poor climb rate
- Very bright peace-time paint scheme.
History
During the 1930s the United States had a vibrant seaplane making industry making ever larger flying boat category of seaplanes. Sikorsky, Boeing, Grumman, Consolidated (of PBY fame), and Martin all vied for the lucrative opportunities of an aircraft that could land almost anywhere on earth with little investment in facilities. Advances in technology lead the US Navy created a few new "system designation" in 1935, with "PB" for "Patrol Bomber" being one of them. Glenn L.

It was also larger, more complex, and 50% heavier.
After testing with a 3/8 scale flying model (Martin 162A Tadpole Clipper), the XPBM-1 prototype first flew in 18 February 1939 proving a solid design, except for stability issue with the horizontal stabilizer and twin tails. To solve this the production PBM-1's horizontal stabilizer was given a dihedral to match the wing but maintained the 90 degree angle to the vertical stabilizer, resulting in an inward cant of the vertical/rudder tail (unlike nearly any other aircraft, like the Be-6).
