Curtiss P40 in Naval Service

US Navy Fighter-Bomber (1940-45), c13,700 built

The P-40 in brief:

The Curtiss P-40 Warhawk was one of the most widely used American fighter aircraft of the early years of World War II. Though often overshadowed by later designs like the North American P-51 Mustang, it played a crucial role across multiple theaters of war.

Manufacturer: Curtiss-Wright
First flight: 1938 (prototype), introduced 1941
Engine: Allison V-1710 liquid-cooled V-12
Top speed: ~360 mph (580 km/h), depending on variant
Range: ~650 miles (1,050 km)
Armament:
Typically 6 × .50 caliber machine guns
Bombs (up to 2,000 lb) or rockets

🛠️ Design & Characteristics

The P-40 was based on the earlier Curtiss P-36 Hawk but upgraded with a more powerful inline engine.
Strengths: Rugged and durable — could absorb heavy damage, Stable gun platform — effective in dives and strafing, Good low-to-medium altitude performance
Weaknesses: Poor high-altitude performance (no advanced supercharger), Outclassed later in the war by newer German and Japanese fighters, Limited climb rate compared to rivals.

🌍 Combat History

China & the “Flying Tigers”: The P-40 became famous with the First American Volunteer Group, led by Claire Lee Chennault. It flew against Japanese aircraft like the Mitsubishi A6M Zero Used dive-and-zoom tactics instead of dogfighting. Iconic shark-mouth nose art.
North Africa & Europe: Operated by the Royal Air Force, where it was called the “Kittyhawk” or “Tomahawk”. Played a major role in the North African Campaign. Provided ground support and air defense
Pacific Theater: Used heavily by the United States Army Air Forces. Battles over New Guinea, Guadalcanal, and the Philippines. Effective in ground attack and escort roles.

🧬 Variants

P-40B/C (Tomahawk): Early versions used by Flying Tigers.
P-40E: Improved armament (6 guns), widely produced
P-40F/L: Used Rolls-Royce Merlin engine (better performance)
P-40N: Lightened, fastest production version

🦈 The Shark Mouth Legend

The famous shark-mouth design was inspired by British pilots and made iconic by the Flying Tigers. It became one of the most recognizable nose arts in aviation history.

⚖️ How It Compared

Feature P-40 Warhawk/Mitsubishi A6M Zero
Speed; Moderate/Good
Maneuverability: Average/Excellent
Durability; High/Low
Firepower: Strong/Moderate
The P-40 couldn’t out-turn the Zero, but it could dive faster, take more hits, use energy tactics to win.

🧠 Strategic Importance

Even though it wasn’t the best fighter overall, the P-40 was available early in the war when better fighters weren’t ready, it was reliable and easy to maintain and exported widely (UK, USSR, China, Australia). It helped buy time for more advanced aircraft to enter service.

The Naval Service of the Curtiss P-40

Obviously the P40 was not designed for carrier service or requested as such. Back in 1936 when the P-36, its predecessor, was barely operational, there were considerations by Curtiss to propose it to the Navy in a modified version, but Grumman by the time firmly imposed itself as a trusted provider... (More to come).
