This page is about the American medium bomber B-25J-1. For other versions, see B-25 (Family).

Description

The B-25J-1 Mitchell is a rank II American bomber with a battle rating of 3.7 (AB/SB) and 4.0 (RB). It was introduced in Update 1.29.

Simply put, the archetype of the medium bomber is the B-25. It has versatile payloads (4 x 500 lb or 3 x 1,000 lb). It is faster than heavy bombers which can achieve over 340 mph in a dive to attack ground targets and as a bonus has offensive armament that allows it to fulfil the role of an air superiority bomber. Defensive gun placements include turrets & gunner stations. The B-25J sports heavy armament to include seven 12.7 mm Browning M2 machine guns. Also, this aircraft is durable, however, if the aircraft happens to sustain a direct hit to the fuel tank, there is a good chance of a fire followed by an explosion.

When flown properly, the B-25 Mitchell is among the best medium bombers in the game, with one of the most potent defensive armaments at its tier. If you enjoy strafing ground targets with the B-25, then consider researching the PBJ-1H with 8 forward-facing .50 cal Browning M2 machine guns and a 75 mm cannon or the PBJ-1J sporting an impressive 12 forward-facing Browning M2 machine guns, both of which are Marine versions of the B-25 airframe and possess all the facets that make the B-25 Mitchell such a legendary aircraft.

Usage in battles

In Realistic battles (and Arcade to an extent), it is highly recommended against exclusively bombing strategic bases and in general to not bomb from high altitudes. It was rarely used this way in combat, and it makes it very easy for enemy fighters to approach and attack you from your defenceless belly. Also, the bomber's maximum payload of 3 x 1,000 lb of bombs is not enough to destroy an enemy base in Realistic battles, which is useless in regards to decreasing ticket count and, most importantly, does not help your team. Thus, leave base bombing to the British heavy bombers you will likely also encounter on your team, whose payloads vastly outclass yours, and instead - if you wish to help your team as much as possible - use your five nose-mounted Browning machine guns on ground targets. Ground target strafing is not only infinitely more exciting than base bombing, but it can also lower the enemy's ticket count drastically, therefore helping your team win. Fly at low altitudes and attack light pillboxes and soft targets with your guns. If you fail to destroy a target, then pitch up and use your turrets to finish it off. Save your bombs for targets your guns cannot kill, such as heavy tanks and heavy pillboxes; the bombsight is very helpful in doing this (something which the dedicated strafing variants such as the PBJ-1J lack). Make sure to use a fuse timer, 3 seconds should be enough when bombing at treetop level with 1,000 lb bombs.

When strafing, be sure to watch your minimap at all times for any incoming enemies so you can adequately prepare for an attack. When being attacked, fly away from the assailant and try to get them on your tail, and manually open fire with your defensive guns, making sure to watch your tracers and adjust the direction of fire, so they hit the target. Remember that turret guns will jam if fired for a long duration, requiring them to be reloaded, which usually takes almost twenty seconds, during which an attacker will most certainly kill you. If the reticle starts blinking, the guns are very close to jamming, so immediately stop firing and wait for the weapons to cool down. Many experienced players will attempt to utilise the dead zones on your belly and the arcs beyond your twin rudders in their attack. If you find an enemy doing this to you, then switch back to flight view and manoeuvre so that they are in the firing arcs of your guns again and try as much as possible to keep them out of your dead zones and, mostly, make their attack as difficult as possible. The attacker will then either eventually lose patience and try for a head-on, or you will get a successful snipe on their aircraft. It is also very advantageous to use the keyboard controls for pitch, roll, and yaw in the gunner view as it will allow you to make small manoeuvres while still concentrating on defending yourself, letting you, for example, dodge fire or roll/pitch/yaw and shoot someone in your dead zones. Also, use Universal belts for your turrets as they will do the most damage to enemies and cause devastating fires.

If you lose tail control for whatever reason, then immediately turn back to the airfield and use combat flaps to keep your nose up. Make a landing by alternating between takeoff and combat flaps and, if needed, landing flaps. Make sure that your speed does not go too low; if you start nosing down with takeoff flaps then do not use landing flaps (unless in an emergency) as you'll lose speed and potentially crash. Instead, engage WEP and wait for your nose to rise. There is no set method for doing this and it takes lots of practice, but making these daring landings is very rewarding. If you lose an engine, do not engage flaps as you will lose speed, end up in a stall and will die, fly straight and slowly make your way back to base, using WEP if needed. If using manual engine controls, close the radiator of the dead engine, feather it, and open the radiator of the working engine to allow you to use WEP all the way back to the airfield without overheating.

Carrier Landing Technique

Approach at 150 km/h (92 mph/80 kt), flaps set to landing. Keep applying about 60% thrust, or as necessary to maintain 150 km/h. Touchdown at the beginning of the carrier runway, slightly to the left to avoid the island. Apply hard braking, immediately retract flaps, and if necessary fire forward-facing guns.

Pros and cons

Pros:

• Can take a beating
• Strong defensive guns
• Versatile bomb load
• Decent speed for a bomber
• A multi-use aircraft
• Forward facing gunner automatically starts firing approx 1,000 m from the target, use as a range finder
• Has forward-facing 50 cal. MGs which are very useful for strafing

Cons:

• Manoeuvres stiffly
• Stiff elevators
• Difficult to pull out of a dive
• Often the B-25 will catch on fire
• No downward-facing defensive armament
• If tail control is damaged, return to base and land utilizing flaps and engine throttling
• 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

In-game description

North American B-25J-1 Mitchell twin-engine medium bomber/ground-attack aircraft

The B-25J (NA-108) was the most largely produced Mitchell variant. The first aircraft of this type left the factory floor in December 1943, and the variant drove the B-25C and B-25D completely out of production by March of the next year.

B-25J bombers had two 1,700 hp Wright R-2600-29 fourteen-cylinder, double-row, radial air-cooled engines with Hamilton Standard Hydromatic 23E50 three-bladed automatic metal propellers.

One feature of this variant was that it could be used both as a bomber and as a ground-attack aircraft.

When used as a bomber, the B-25J-1's armament was: one fixed front machine gun (with 400 rounds) and one mobile machine gun (with 300 rounds) mounted on the navigator's cockpit in the forward fuselage; four front machine guns, with 400 rounds each, mounted in pairs on both sides of the lower fuselage section, near the pilot's cockpit; a Bendix A-9 upper turret housing twin machine guns, with 400 rounds each; a twin Bell M-7 rear mount, with 600 rounds each; and two machine guns, with 600 rounds each, in the fuselage blisters on the starboard and port sides. All gun emplacements had 12.7 mm Colt-Browning ANM2.5 machine guns. The total number of machine guns was 12.

Thus, the B-25J was practically as good in its armament as heavy bombers like the B-17 or the B-24, except for coverage from below.

To use the B-25J-1 as a ground-attack aircraft, the nose section with the navigator/bombardier's cockpit could be easily removed and replaced by a solid unglazed nose with a battery of eight 12.7 mm Colt-Browning ANM2.5 machine guns, with 400 rounds each. Thus the number of front machine guns was increased to 12, and the total number of guns to 18.

The B-25J-1's maximum bomb capacity was 4,000 lb (1,815 kg). Starting with the 151st machine, one bomb rack, meant to suspend a 2,000 lb (908 kg) bomb, was removed from production B-25J-1 bombers, since it was almost never used in combat units and did nothing but take up a lot of space in the bomb bay.

The aircraft usually carried three 1,000 lb (454 kg) or two 1,600 lb (726 kg) bombs. Different combinations of bombs of smaller sizes were also used. 10 kg parachute bombs were used, as well. The B-25J could carry a Mk.13 torpedo weighing 907 kg. In addition, removable bomb racks for bombs up to 250 kg could be mounted under the wing panels.

When used as a bomber, the aircraft had a crew of six people: two pilots, a navigator/bombardier/gunner, a turret gunner/engineer, a radio operator/waist gunner, and a tail gunner. When used as a ground-attack aircraft, the crew consisted of five people, excluding the navigator/bombardier.

Both pilot seats were equipped with an armoured backrest. One armour plate was located behind the instrument panel, and the second was under the cockpit windshield. Two armour sheets were fixed outside to the sides. Armour protection was provided for all gunners.
