Curtiss P-40 E-N Aircraft Engineering Blueprints - Digital Download
Extensive collection of original Curtiss P-40 E through N aircraft blueprints converted directly from microfilm to electronic format. These are authentic, unretouched archival scans preserving the original drawings exactly as they appeared in the wartime engineering archives, perfect for aviation historians, researchers, restorers, modelers, and enthusiasts who value documentary authenticity.
Definitive Collection with Free Lifetime Updates: This is a living collection that we continuously expand and refine. As we acquire additional P-40 documentation, technical bulletins, or variant-specific materials, we update this collection and provide free lifetime updates to all purchasers. Your one-time purchase guarantees access to all future additions and improvements to this collection.
Historical Note
The Curtiss P-40 Warhawk stands as one of the most recognizable and widely-produced American fighter aircraft of World War II. Developed from the earlier P-36 Hawk, the P-40 first flew in 1938 and entered service with the U.S. Army Air Corps in 1940. While it lacked the high-altitude performance and speed of later fighters like the P-51 Mustang or P-47 Thunderbolt, the P-40 proved to be a rugged, reliable, and effective fighter-bomber in the low to medium altitude roles where it excelled.
The P-40's greatest fame came with the American Volunteer Group (AVG) "Flying Tigers" in China, where Claire Chennault's pilots used the aircraft's superior diving speed and ruggedness to devastating effect against Japanese fighters. The distinctive shark-mouth nose art became an iconic symbol of American air power in the Pacific theater. P-40s served with distinction in North Africa, the Mediterranean, the Pacific, China-Burma-India theaters, and the Soviet Union under Lend-Lease.
Production continued from 1939 to 1944, with approximately 13,738 aircraft built across numerous variants. The E and N models covered in this collection represent mid to late production variants with improved armament, armor protection, and engine performance. The P-40E introduced six .50 caliber wing-mounted machine guns, while the P-40N was the lightest and most maneuverable variant, optimized for Pacific theater operations.
Today, the P-40 is no longer in active military or civilian service, though a small number of restored examples fly at airshows and in private collections. These aircraft are prized by warbird enthusiasts and command premium prices, with airworthy examples typically valued between $1,500,000 and $3,500,000 depending on variant, condition, and restoration quality.

This collection provides extensive coverage of the P-40E through P-40N airframe structures, assemblies, and systems as documented in the original Curtiss-Wright engineering archives through mid-1943 production.
Please Note: This collection represents authentic archival scans transferred directly from original microfilm without digital cleanup or enhancement. We preserve the drawings exactly as they appeared in the wartime archives, including any aging, annotations, or historical markings. This approach prioritizes documentary authenticity for researchers and historians. Other sources may offer digitally cleaned or enhanced versions of similar drawings.
Engineering Norms and Standards
The P-40 series was designed and manufactured under U.S. Army Air Corps specifications and military airworthiness standards of the late 1930s and early 1940s. Curtiss-Wright engineering practices emphasized robust construction suitable for combat operations, field maintenance, and operation from austere forward airfields. Materials specifications followed contemporary military standards (AN, MS, NAS) for aircraft-grade aluminum alloys, steel structures, and fabric-covered control surfaces. Engine installations varied by model, with Allison V-1710 liquid-cooled V-12 engines across all P-40 variants.
