Hello everybody. Today, I’d like to suggest the Vultee XA-41 for US Aviation in War Thunder. Originally designed as a dive bomber, the XA-41 was later developed into a low-level ground attack aircraft by Vultee for the US Army. Its design included features that would later become familiar in aircraft like the AD Skyraider. While the XA-41 successfully passed flight tests and demonstrated excellent performance, the Army ultimately decided not to enter it into production or service during World War II. This was primarily due to the P-47 Thunderbolt and other fighter-bombers already fulfilling the same role, making the XA-41 redundant.
Key Characteristics
- The last WWII “dive-bomber” attack aircraft developed for the US military
- Powered by a 3,000-hp Pratt & Whitney R-4360-9 radial piston engine
- Armed with 4 x 0.50-cal. machine guns and 4 x 37-mm autocannons
- Access to decent ground weaponry
History
In September 1942, the US Army approached Vultee to perform a study for a single-seat dive bomber and develop it with a more powerful powerplant, the 3,000-hp XP-4360 radial piston engine. Vultee was tasked with competing against Kaiser-Fleetwings and Curtiss, who were also commissioned by the Army to design new aircraft. Inspired by the successful exploits of the German Luftwaffe’s dive bombers during the early stages of World War II, the US sought to modernize its dive bomber fleet, even after the Brewster XA-32 program had failed spectacularly.
Vultee responded with its Model 90 design, which impressed the Army enough to secure a contract to build two prototypes on November 10, 1942. In March 1943, Vultee presented a mockup, which passed a successful Army inspection. However, just weeks later, the Army changed the mission requirements for the original dive bomber to a dedicated low-altitude attack aircraft. Changing war situations in Europe revealed the vulnerabilities of dive bombers, prompting the Army to reconsider their role in combat operations.
This decision caused delays, and a new contract was signed on April 30, 1943. Vultee, which would later become Convair, began redesigning the aircraft for its new role. Development progressed without major issues, and by September 1943, the first XA-41 prototype was nearly half-complete. However, the Army decided it no longer needed the XA-41, as existing P-47 Thunderbolts and other fighter-bombers were already fulfilling the same role.
Despite this, the Army’s Materiel Division encouraged Vultee to complete the XA-41 and conduct flight tests. By November 20, 1943, the first prototype was 75% finished, but the second prototype was canceled. The aircraft was completed with an all-metal construction and designed to be heavily armored. It was powered by an R-4360-9 engine with a four-blade Hamilton Standard propeller and featured a shallow internal bomb bay that could carry various payloads, including four 500-pound bombs, two 1,600-pound bombs, a torpedo, or additional fuel tanks. Its armament included four .50-caliber machine guns (400 rounds per gun) in the outer wings and four 37mm cannons (30 rounds per gun) in the inboard wings, all mounted outside the propeller arc.
The XA-41 first flew on February 11, 1944, from Vultee Field, California, reaching a top speed of 353 mph (584 km/h) and landing at March Field, California. Subsequent tests revealed the aircraft had good handling and impressive agility. Minor issues, such as the lack of tail wheel doors and a spinner, were quickly resolved.
The Army accepted the XA-41 on June 25, 1944. On its 60th flight, the aircraft was ferried to Eglin Field, Florida, for further testing. Despite proving to be an excellent low-altitude attack aircraft with exceptional turning ability, the Army lost interest in the program. They deemed the XA-41 unsuitable for self-defense against enemy fighters, as its top speed was insufficient compared to faster fighters already in service. With existing fighter-bombers effectively fulfilling the same role, the XA-41 was no longer a priority.
The US Navy had an interest in the XA-41 and briefly evaluated the aircraft at Patuxent River, Maryland, to determine its suitability for carrier operations. However, they ultimately decided it was unnecessary for their fleet and handed over the prototype to Pratt & Whitney in East Hartford, Connecticut, on August 22, 1944. Pratt & Whitney used the XA-41 as a testbed for engine development, including a supercharger-mounted engine. The aircraft remained in use for testing purposes until it was finally scrapped in 1950.

Conclusion | Why it should be in the game
Sadly, the XA-41 never made it to production. If it had, it might have become the Army Air Forces’ equivalent to the Navy’s AD Skyraider—a dedicated ground-attack aircraft that proved essential during the Korean and Vietnam Wars. The Air Force lacked its own dedicated attack aircraft until it received A-1 Skyraiders handed down from the Navy during the Vietnam War. This highlighted the need for a dedicated Air Force ground-attack platform, eventually leading to the development of the A-7 Corsair and A-10 Warthog.
In War Thunder, the US aviation currently lacks fast attack aircraft with a single-seat configuration specifically designed for the Army’s ground-attack role. I believe the XA-41 would fill this gap nicely, offering an alternative aircraft with a BR lower than the AD Skyraiders.
