Strengths

Forward Firepower: With six fixed .50 caliber machine guns in the nose, the B-25 has the same sustained firepower as most US fighters.

Defensive Firepower: Though not as heavily defended as the B-17, the Mitchell had six .50 caliber guns for defensive purposes, which exceeds that of any other medium bomber.

Weaknesses

Speed: With a top speed of about 275 mph the Mitchell is outclassed by the German and Soviet medium-bombers.

History

After production of the B-25D model, several experimental models were produced to test various equipment additions. The most startling was the conversion of the bomber into a ground attack aircraft by sticking a 75mm field gun in the nose. Augmented by a pair of .50 caliber machine guns in the nose, the B-25G could pack a potent punch. However, the large gun installation was not an unqualified success. While it could certainly do serious damage to anything it hit, its low rate of fire and the need to fly slowly to aim the gun, made the Mitchell an attractive target for ground fire, which didn't endear the plane to its crews.

The "H" model replaced the 75mm gun with six .50 caliber machine guns, bringing the total to eight .50s. Additionally, the top turret was moved forward to a position just behind the cockpit where its guns could also be brought to bear on the pilot's target. A new tail gun position was added and the troublesome remotely operated belly turret was officially removed (it was usually removed in the field to save weight). Finally, rocket rails were optionally installed under the wings, allowing it to fire eight 5" rockets as part of its forward barrage.

As the selection of targets changed, the 75mm gun became increasingly useless and the "J" model featured a return to the glazed nose and bombardier station. The forward firepower of the plane was retained by mounting two .50 caliber machine guns in the right side of the nose to augment the four in the blisters on the sides of the fuselage. Over 4300 "J" models were produced, making it the most numerous of Mitchell variants.
