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.

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 defenceless. 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 lb!)
• If aimed properly, and using the right belts, defensive armament is very deadly
• Defensive armament has great coverage

Cons:

• Terrible survivability, thanks to the fact that it has no armour
• Gunners can easily be taken out, especially the tail gunner (no armour, and no bulletproof glass either)
• Vulnerable to attacks from directly below
• Not very fast

History

Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
