The DAF always outnumbered its Axis opponents and concentrated on long-range interdiction and direct tactical Eighth Army support. Unfortunately, these tactics meant that the faster Messerschmitt Bf 109s of "Jadgdeschwader" 27 usually had the advantage of height and surprise over the low-level, slow-flying DAF fighters and losses were correspondingly high. In 1942, the DAF reorganised its tactics and introduced better aircraft. Spitfires were eventually used for air superiority, becoming operational in August 1942, which allowed the DAF to gain air superiority.
