The '''{{Specs|name}}''' is a rank {{Specs|rank}} premium Russian bomber {{Battle-rating}}. 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 [[B-25J-20|USAAF counterpart]]. The minor differences are the reinforced steel pilot seats and extra armour for the dorsal gunner.
+
The '''{{Specs|name}}''' is a rank {{Specs|rank}} American bomber {{Battle-rating}}. It was introduced in [[Update 1.29]].
  
 
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 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.

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 444 km/h (275 mph) under ideal conditions and a max airframe speed of 580 km/h (360 mph), the B-25 is relatively fast for a bomber, but while climbing, can go no faster than 280 km/h (175 mph) 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:'''
*
+
* 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
 +
* Able to land on an aircraft carrier
  
 
'''Cons:'''
 
'''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 unmanoeuvrable for any real dogfighting of any kind
 +
* Steel construction makes this plane particularly heavy, and a small payload limits this plane's ability to be used as a tactical or strategic bomber
 +
* 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

"North American B-25J-30 Mitchell twin-engine medium bomber/ground-attack aircraft
+
North American B-25J-20 Mitchell twin-engine medium bomber/ground-attack aircraft
 +
 
 +
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.
 +
 
 +
Aircraft of the B-25J-10 series were equipped with external bomb racks under the wings. The heaters at the waist gun positions were found to be inefficient and were no longer installed.
 +
 
 +
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.
  
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.
+
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.
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.
+
An emergency brake system was also installed. Beginning with machine No. 44-29340, Holley 1685RB carburettors were fitted on the bomber's engines.
  
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.
+
A Norden M-9 bombsight was mounted on the aircraft built for the USAAF, and a simpler Wimperis D-8 on the machines to be exported. In the USSR, locally produced OPB-1 (daylight version) and NKPB-7 (night version) bombsights were mounted on В-25s.
  
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.
+
In addition, В-25 aircraft in the Soviet Union were equipped with an inert (exhaust) gas fire suppression system for the fuel tanks.
  
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."

Description

GarageImage B-25J-20.jpg


The B-25J-20 Mitchell is a rank II American bomber with a battle rating of 4.0 (AB/RB) and 4.3 (SB). It was introduced in Update 1.29.

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.

  • 2 x 12.7 mm Browning M2 machine guns, tail turret (600 rpg = 1,200 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 444 km/h (275 mph) under ideal conditions and a max airframe speed of 580 km/h (360 mph), the B-25 is relatively fast for a bomber, but while climbing, can go no faster than 280 km/h (175 mph) 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
  • Able to land on an aircraft carrier

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 unmanoeuvrable for any real dogfighting of any kind
  • Steel construction makes this plane particularly heavy, and a small payload limits this plane's ability to be used as a tactical or strategic bomber
  • 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

In-game description

North American B-25J-20 Mitchell twin-engine medium bomber/ground-attack aircraft

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.

Aircraft of the B-25J-10 series were equipped with external bomb racks under the wings. The heaters at the waist gun positions were found to be inefficient and were no longer installed.

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.

An emergency brake system was also installed. Beginning with machine No. 44-29340, Holley 1685RB carburettors were fitted on the bomber's engines.

A Norden M-9 bombsight was mounted on the aircraft built for the USAAF, and a simpler Wimperis D-8 on the machines to be exported. In the USSR, locally produced OPB-1 (daylight version) and NKPB-7 (night version) bombsights were mounted on В-25s.

In addition, В-25 aircraft in the Soviet Union were equipped with an inert (exhaust) gas fire suppression system for the fuel tanks.

B-25J aircraft were not only supplied to the USAAF. 314 machines were delivered to the British RAF, where they were operated under the designation of Mitchell Mk.III. It was under the Lend-Lease Agreement that these bombers were also supplied to the USSR, Canada, Australia, and China. After the war, В-25Js were supplied to France, the Netherlands, Peru, Venezuela, and Indonesia.
