Even during testing of the high-speed XP-86 Sabre prototypes, the aircraft experienced significant stability issues that limited their maximum safe flight speed. Designers attempted to solve this problem in various ways, but it could not be fixed on the production F-86A without significant design changes. North American engineers then decided to create a modified version of the aircraft with an all-flying tail and a full power-operated control. This solution improved the aircraft's performance, solving the previous limitations on its speed. Otherwise, the aircraft was nearly identical to the F-86A, and 360 F-86E aircraft were built by 1950.

On July 31, 1950, development began on a new modification featuring a more powerful, fuel-efficient J47-GE-27 engine. After minor delays in engine development, production of the F-86F-1 began in December 1951. This was followed by the F-86F-5, F-10, F-15, and F-20, which were equipped with larger fuel tanks, new radio stations, and sights. Following the release of the F-20, the U.S. Air Force requested a fighter-bomber, resulting in two identical modifications: the F-86F-25 and F-86F-30. The only difference was where they were produced: the F-86F-25 at the Columbus plant and the F-86F-30 at the Inglewood plant. The most significant change was the ability to install two pylons on each side of the wing instead of one. A total of 340 F-86F-25s were built, making it the most common F-86 during the Korean War. However, they did not remain in service with the US Air Force for long—only until 1955. The Air National Guard continued to use these aircraft until 1965.

The F-86F-25 was introduced in Update 1.35. In terms of flight characteristics, it is the familiar Sabre that American pilots have known for a long time. The aircraft is easy to learn and does not require a lot of experience. Its disadvantages include a low thrust-to-weight ratio, a low climb rate, and rather weak armament.
