The British Royal Air Force's introduction was averted on the initial Open Beta release but was then added in the late stages of beta testing as the 5th nation in the game.
The R.A.F. doctrine envisioned the employment of fighter aircraft for intercepting enemy aircraft and gaining superiority on the battlefield. The Spitfire, a major British fighter, was an outstanding example, optimized for mid-altitude maneuvering combat and high-altitude interception. Jet aircraft in this tech branch generally follow this concept.
British heavy fighters are worth a special mention. Some of them had been initially developed as bombers but were later modified into fighters. This is why British heavy fighters often feature different designs which are hard to fit in a single concept. Jet-powered heavy aircraft are primarily represented by high-altitude interceptors.
