Strengths

Durability: The P-40E continued the trend of being able to sustain great amounts of battle damage.

Guns: Six .50 caliber machine guns with 280 rpg gives the Warhawk pilot a good combination of hitting power and firing time.

Weaknesses

High Altitude Performance: Despite the newer engine, the P-40E is still rather sluggish and unresponsive at high altitude. In particular the climb rate and ceiling were poor compared to contemporaries such as the Spitfire and Bf-109.

History

Early in 1940 the new Allison V-1710-39 engine became available, and Curtiss set about redesigning the P-40 to accommodate the new power plant. The new P-40D model was visibly different from the P-40C, but in fact bore the new Curtiss development designation "Hawk 87A".

The most visible difference from earlier P-40s was the addition of a deeper radiator "chin" under the engine. This new engine arrangement necessitated the removal of the nose-mounted machine guns in favor of placement in the wings, two .50 caliber machine guns being mounted in each wing with 280 rpg.

After a production run of only 22 P-40Ds an extra .50 caliber machine gun was mounted in each wing, the subsequent model being designated the P-40E by the US Army and the Kittyhawk I by the RAF. In addition to the improved armament, the "E" model incorporated newer hydraulic gun chargers, which replaced the unreliable mechanical charging system that was generally bypassed in the field. Additionally, the P-40E could carry either a 52-gallon drop tank or a 500 lb. bomb under the fuselage.
