The H-81A-2 was an export version of the P-40 Warhawk, very similar to the P-40C, these aircraft were exported to China and flown by the Flying Tigers (American Volunteer Group). These models were not very liked by their pilots, they lacked drop tanks for extra range, bomb racks on the wings, their engines were very vulnerable in combat to leaks and overheating, and the base version had no radios, so improvised radio transceivers were installed. The plane also had very poor performance at high altitudes and a slow climb rate. The aircraft was not liked by ground crews either, lack of spare parts and components were common and many damaged aircraft stayed on the ground for years without flying. However, even though it was less agile than the Japanese fighters, its heavy construction and strong airframe meant that the pilot had a decent amount of protection from bullet impacts and the airframe could withstand emergency landings.

It was introduced in Update 1.91 "Night Vision" as a premium pack in the Gaijin store, though it was removed from sale after the 2020 May Sale. The H-81A-2 is an export version of the US P-40 Warhawk and its appearance is very similar to the P-40C. It shares the nose-mounted .50 calibre machine guns of the earlier variants of the P-40, which allows a denser cone of fire in contrast to later revisions of the aircraft. This firepower helps the H-81 stay on par with other similar fighters. However, the H-81 has poor high altitude performance and its climb rate is mediocre at best, but it's still important to climb to high altitudes at the start of the match.
