The air frame makes this plane a particularly difficult target to bring down, however there are four main blindspots to be considered: Level with the leading edges of the wings, the complete underside, and each side in the rear presented by the twin tail. These are the easiest areas to kill an opposing B-25. With a max speed of 250 MPH under ideal conditions and a max air frame speed of 360 MPH, The B-25 is relatively fast for a bomber, but while climbing, can go no faster than 175 with optimal pitch. The twin engines makes for good acceleration, and allows the plane to get to an airfield to land, given you are at altitude and can maintain airspeed. This plane makes a great strategic bomber, but its wings make for nice large targets. The best way to ward off enemy fighters is to bank in toward them, giving your top gunner a chance to damage them before they can cause any real damage. Always try to fly at treetop level to cover the blindspot on the underside, or fly with bombers that have belly gunners, so you are fully covered. Also try to fly with friendly fighters, as they will prove invaluable to your survival. If you wind up with an enemy fighter or attacker on your tail, reduce engine power and adjust trim so you retain level flight, but give all rear facing gunners the ability to damage your opponent.

 +
As its mass production progressed, the B-25J was continually improved, but in most cases this concerned the aircraft's equipment or armament and not its airframe or power unit. Aircraft of the B-25J-5 series had new multi-purpose N-3C gunsights (everywhere but on the waist turrets) and a newly introduced alcohol windshield washing system for the pilot's cockpit. Also, blast reducers were installed on the barrel muzzles of the upper and waist machine guns.

Replacement of the sights was completed with the B-25J-15 bombers; now, the waist turrets were also equipped with the new N-8A optical sights. In addition, a backup iron sight was installed for the pilots. All machines of these series were produced with one fixed machine gun in the bombardier's cockpit.

Aircraft of the B-25J-20 series had a second fixed 12.7 mm Colt-Browning ANM2.5 machine gun, with 400 rounds of ammunition, mounted in the bombardier's cockpit. An additional armor plate was provided in the floor under the bombardier's seat. The cap glazing of the upper turret was reinforced. The mobile 12.7 mm Colt-Browning ANM2.5 machine gun in the front cockpit was shifted upward slightly so that the ammunition box of the second fixed machine gun would not interfere with its operation.

Survivability and armour

  • 10 mm steel - front, sides & rear of the cockpit
  • 10 mm steel - the rim of pilot seats
  • 8 mm steel - below nose gunner
  • 8 mm steel - pilot seats
  • 9.5 mm - bulkhead after of dorsal turret
  • 6.35 mm steel - aft of waist gunners
  • 9.5 mm steel - tail turret

Armaments

Offensive armament

Main article: Browning M2 (12.7 mm)

The B-25J-20 is armed with:

  • 2 × 12.7 mm M2 Browning machine gun, nose-mounted (400 rpg = 800 total)
  • 4 × 12.7 mm M2 Browning machine gun, cheek-mounted (400 rpg = 1,600 total)

Suspended armament

Main articles: AN-M30A1 (100 lb), AN-M57 (250 lb), AN-M64A1 (500 lb), AN-M65A1 (1,000 lb)

The B-25J-20 can be outfitted with the following ordinance:

  • 12 x 100 lb AN-M30A1 bombs
  • 4 x 250 lb AN-M57 bombs
  • 4 x 250 lb AN-M57 bombs + 8 x 100 lb AN-M30A1 bombs
  • 8 x 250 lb AN-M57 bombs
  • 8 x 100 lb AN-M30A1 bombs + 2 x 500 lb AN-M64A1 bombs
  • 4 x 500 lb AN-M64A1 bombs
  • 10 x 100 lb AN-M30A1 bombs + 1 x 1000 lbs AN-M65A1 bomb
  • 3 x 1000 lb AN-M65A1 bombs

Defensive armament

Main article: Browning M2 (12.7 mm)

The B-25J-20 is defended by:

  • 1 x 12.7 mm M2 Browning machine gun, nose turret (300 rpg)
  • 2 x 12.7 mm M2 Browning machine gun, tail turret (600 rpg = 1,200 total)
  • 2 x 12.7 mm M2 Browning machine gun, dorsal turret (400 rpg = 800 total)
  • 1 x 12.7 mm M2 Browning machine gun, 2 x beam turret, (250 rpg = 500 total)

Usage in battles

The airframe makes this plane a particularly difficult target to bring down, however, there are four main blindspots to be considered: Level with the leading edges of the wings, the complete underside, and each side in the rear presented by the twin tail. These are the easiest areas to kill an opposing B-25. With a max speed of 250 MPH under ideal conditions and a max airframe speed of 360 MPH, The B-25 is relatively fast for a bomber, but while climbing, can go no faster than 175 with optimal pitch. The twin engines make for good acceleration and allow the plane to get to an airfield to land, given you are at altitude and can maintain airspeed.

This plane makes a great strategic bomber, but its wings make for nice large targets. The best way to ward off enemy fighters is to bank in toward them, giving your top gunner a chance to damage them before they can cause any real damage. Always try to fly at treetop level to cover the blind spot on the underside, or fly with bombers that have belly gunners, so you are fully covered. Also try to fly with friendly fighters, as they will prove invaluable to your survival. If you wind up with an enemy fighter or attacker on your tail, reduce engine power and adjust trim so you retain level flight, but give all rear facing gunners the ability to damage your opponent. Never fly in a straight line while fending off attackers!!

Pros and cons

Pros:

  • Very effective front facing armament of 6 x 12.7 mm machine guns allows for engaging enemy bombers at the start of the match, or incoming fighters
  • Durable airframe
  • Heavy defensive armament on both left and rights sides and especially on the rear
  • Can provide initial cover for other bombers until fighters reach their altitude
  • Can be used as both a tactical and strategic bomber

Cons:

  • The belly of the aircraft is a massive blind spot in the aircraft's defence
  • Slow
  • Poor climb rate and energy retention
  • For the most part, the offensive armament will only be useful in attacking enemy bombers, ground targets, or engaging fighters head-on, as the plane is too unmaneuverable for any real dogfighting of any kind

  • The Elevator can be shot off by an enemy plane easily. This can cause it to become uncontrollable in certain situations. However, it can still be controlled by operating flaps or adjusting engine power

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 big, 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>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).
