Description

GarageImage B-25J-30 (USSR).jpg


The ▂B-25J-30 Mitchell is a rank III premium Russian bomber with a battle rating of 4.0 (AB/RB) and 4.3 (SB). This aircraft was introduced in Update 1.35. It costs 1,450 Golden Eagles. The B-25J-30 is a lend-lease vehicle for the Soviets and is essentially identical in-game to the USAAF counterpart. The minor differences are the reinforced steel pilot seats and extra armour for the dorsal gunner.

Design of the B-25 was the result of years of work and failed bids to win contracts with the United States Army Air Corps (USAAC). Initially designed to meet requirements for a payload of 1,200 lb (540 kg), a range of 1,200 mi (1,900 km) and flying at speeds faster than 200 mph (320 kph), prototypes were built, tested and refined. Although the original XB-21 and NA-40 never materialized into a production aircraft, requirements from the USAAC came out in March of 1939 for a medium bomber carrying a payload of 2,400 lb (1,100 kg) over 1,200 mi (1,900 km) at speeds around 300 mph (480 kph), North American modified their design of NA-40 and developed the NA-62 which went into prototype testing as the YB-25 and then ordered into production as the B-25.

The B-25 turned out to be the archetype of the medium bomber, carrying upwards of 3,000 lb (1,361 kg) of bombs and could fly at speeds up to 340 mph (547 kph). This twin-engine bomber was fast, it could carry a large payload for its size and had several defensive turrets and gunner stations at which it could defend itself from almost any angle. To increase its versatility, several models had forward-facing fixed machine guns fitted into the nose and the cheeks of the aircraft. Later models opted to removed the glazed nose and bombardier/nose-gunner station and outfit more machine guns and even a 75 mm autocannon for strafing ground targets and especially ships. This medium bomber at times acted more like a heavy attacker opting for low-level flights which would skim treetops and the ocean to sneak up on unwary targets. It was not uncommon for B-25s to fly just above the mast/smokestack height of enemy ships when attacking.

As later models moved from the dedicated bomber position and morphed into more of an attacker role, bomb payloads were reduced to allow for more armour around the cockpit and more offensive weapons and ammunition to fill the attacker mode it took on, especially under the command of U.S. Marine Corps squadrons. With more than 10,000 B-25 aircraft variants built, they saw action in all theatres of war and were even subject to part of the lend-lease program which China and the USSR benefitted from. So versatile was this aircraft that a flight of them were specifically outfitted and their crews trained to take off from an aircraft carrier and bomb mainland Japan in a daring raid. Impressive for an aircraft not meant to take off from an aircraft carrier.

The B-25 is a fantastic bomber, attacker or both and will suit many different pilots and their different approaches to the battlefields found in War Thunder. The tail gunner has been known to set many fighters alight with their dual .50 calibre machine guns and help to prolong the life of this bomber to allow the pilot to make it to their target whether it is to bomb it or strafe it.

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
  • 38 mm Bulletproof glass - tail turret

Rugged, sturdy, though, the B-25 is all of those things. Featuring crew armour protection that outclasses the B-17 Flying Fortress in a handier, smaller design, the B-25J is a tough nut to crack and even harder to devoid of the crew. Calibres above 20 mm are a must for a quick kill, otherwise, the B-25 will repay in kind. Gunner positions throughout the bomber effectively cover the front, sides, top and rear of the aircraft with just the underbelly left relatively unprotected to fighters rising in a power climb. The rear gunner with his dual .50 calibre machine guns is especially devastating when they are trained on a tailing enemy fighter.

The two Wright R-2600 air-cooled radial engines are themself hard to destroy and with dropped payload, the B-25J can keep flying on just a single damaged engine, denying under armed fighters the ability to lethally cripple it. Yet this aircraft does have an Achilles heel, its fuel tanks. While present in all planes, the armour, crew and bomb bay take up all the necessary space within the fuselage, while leaving only space in the wings to house the fuel tanks. A common downfall of this aircraft is the structural failure of the wing spar due to wing fires of the fuel tanks.

Pros and cons

Pros:

  • Very effective front-facing armament of 6 x 12.7 mm machine for aerial attack or ground strafing
  • Durable airframe which can take a beating
  • Heavy defensive armament on both left and rights sides and especially the tail gunner
  • Can provide initial cover for other bombers until fighters reach their altitude
  • Can be used as a tactical bomber, strategic bomber or as an attacker
  • Able to land on an aircraft carrier
  • Good dive speed

Cons:

  • The belly of the aircraft lacks any defence
  • Poor climb rate and energy retention
  • Less effective as a dogfighter due to its size, however, can perform Boom & Zoom without too much manoeuvring
  • Less effective as a high-altitude bomber (accuracy), better for mid to low altitude bombing
  • The elevator is easily shot off, the plane can still be controlled using flaps and 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 an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template.

In-game description

"North American B-25J-30 Mitchell twin-engine medium bomber/ground-attack aircraft

New armoured pilot seats appeared in the B-25J-25 series. Also, the wing leading edge was reinforced. Beginning with machine No. 44-30111, additional armour was fitted to the upper fuselage to prevent the turret-mounted machine guns from inadvertently hitting the bomber. From aircraft No. 44-30309 on, the Americans provided for the mounting of chemical spray tanks, similar to the Soviet VAPs, on external bomb racks.

The B-25J-30 had T-64 launchers for unguided HVAR missiles installed under the wing panels. The mechanical bomb hoist was replaced with an electric one. The gunsights were upgraded again, and a new high-precision Norden N-9B bombsight was mounted on the aircraft, beginning with No. 44-86793.

Provisions were made for carrying new guided glide bombs from plane No. 44-86692 on. The work to equip the aircraft with such bombs had begun back in 1943. GT-1 glide bombs were actually torpedoes with wings and tail fins. In July 1945, they were used to strike ships at the Japanese ports of Sasebo and Nagasaki. In Sasebo, they managed to damage and set fire to two vessels. The third bomb did not hit its target but dropped on the harbour works.

Although the В-25 had a good flight range, sometimes it was not sufficient, given the size of the Pacific Ocean Theatre. Fuel quantity had to be increased, so B-25s were modified on front-line airfields. Various additional tanks, removed from aircraft of other types, were mounted in the fuselage near the radio set.

A total of 4,318 B-25J aircraft were delivered. 72 more bombers were practically ready when their production was discontinued. Some of those machines were nevertheless completed later. 800 B-25Js of the total number were assembled directly as the ground-attack aircraft version. In addition, North American produced so-called conversion kits, which allowed the aircraft to be quickly converted on a front-line airfield. Thus, the real number of machines flying as the ground-attack aircraft version significantly exceeded the original eight hundred."
