Description

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


The ␗B-25J-30 Mitchell is a rank III Chinese bomber with a battle rating of 4.0 (AB/RB) and 4.3 (SB). It was introduced in Update 1.91 "Night Vision".

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.

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.

  • 1 x 12.7 mm Browning M2 machine gun, nose turret (300 rpg)
  • 2 x 12.7 mm Browning M2 machine guns, dorsal turret (400 rpg = 800 total)

  • 2 x 12.7 mm Browning M2 machine guns, tail turret (600 rpg = 1,200 total)

Usage in battles

One of the most efficient yet dangerous way of earning RP with the B-25 is to first dive-bomb a base at low altitude, then strafe soft ground targets or fend off incoming fighters.

For such playstyle, it is best to choose the 3 x 1,000 lb bombs loadout to destroy a base in one go. Universal belt is great for the offensive and defensive guns, and their convergence is up to you. At the start of the match, choose the nearest base from you and tag it on the map, this way other bombers are not likely to fight for that base. Now, with WEP, directly dive at the front edge of the base. The B-25 has a reasonably good dive acceleration and can soon dive at more than 500 km/h. However, keep watching the air speed as the B-25 will experience severe lock-up at more than 500 km/h and will rip at 570 km/h. The fastest way to get to the base is to maintain air speed around 550 km/h. While on your way, you can have a look at what ground targets are near that base. Make sure your altitude is well below 500 m when approaching the base. Flying this low can prevent the opponents from attacking from below, which minimises the lack of belly gunners of the B-25. Also, most fighters tend to chase after low-flying bombers, so if you successfully lured some enemies into chasing you, you have already done a great job for the friendly fighters, as they now have altitude advantage over the ones at your tail.

Once the base is near, level out and aim at it with the bombsight. Drop all 3 bombs at the center of the base, and immediately turn towards the nearest ground targets. Your priority should be soft targets like trucks, AA vehicles and artilleries, since they will be destroyed with a short burst of your 6x .50 cals. If you are lucky and found a long convoy of trucks, you will get plenty of RP out of it.

While strafing, you must constantly look around, above and on the minimap for any potential threats. If an enemy fighter dives on you, drop your altitude to tree-top level at once, this way the fighter is forced to face your tail guns and turrets. Use the gunner view to fire at it, but remember, leading the target correctly requires lots of practice. For the enemy fighter, there will always be 2-5 .50 cals spraying bullets at it, which is quite deadly for Japanese fighters like the A6M2/M3. Sometimes it only requires a single bullet to set those fragile fighters on fire, or to damage their large radial engines or coolers. However, the B-25 is equally likely to be set aflame or lose its tail very quickly. Once on fire there is nothing you can do except keep spraying bullets until you are destroyed.

Enemies worth noting:

  • ▅Fw 190 A-5: This Japanese Fw 190 is the same as the German ones. It is armed with 4 x 20 mm cannons and 2 x 7.92 mm MGs, which are very destructive and have plenty of ammo, allowing them to easily critically damage the B-25 in a burst. The plane itself is fairly well armoured, especially the thick, sloped windscreen protecting the pilot. Therefore the deadly firepower and good protection make the Japanese Fw 190 a great threat to the B-25, as China always faces Japan in air RB. When a Fw 190 is tailing the B-25, concentrate your fire on its big radial engine for better chance of crippling it. If you can, try to fly towards the higher-flying teammates to lure the Fw 190 into an altitude disadvantage.
  • A6M2 / M3: These fighters are well known for their manoeuvrability and climb rate. However when they are at your 6, their manoeuvrability is no longer an advantage as they have to constantly chase after you, making themselves a great target. The Zeros are poorly protected with a high chance of being set on fire, and their 20 mm cannons lack the damage to effectively hurt the B-25. When dealing with them, again, aim at their engine or even the unprotected cockpit for a pilot snipe.

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 from weak guns like 20mm Type 99
  • 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 acceleration

Cons:

  • Manoeuvres stiffly, cannot turn well
  • Rudder severely locks up over 400kph, meaning it cannot adjust its aim in time and need a second pass.
  • Difficult to pull out of a dive due to elevator lockup.
  • Often the fuel tank in wings will catch fire, leading to the failure of spars.
  • No defensive armament on belly
  • Relatively low payload compared to a heavy bomber
  • Forward facing gunner will automatically fire at approx 1,000 m, alerting your target
  • Low energy retention; any attacks that require manoeuvring will cost speed and altitude

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).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
