Spitfire

The Supermarine Spitfire was a British single-seat fighter aircraft used by the Royal Air Force during World War II. Widely regarded as one of the finest fighters during the war, it is seen in Call of Duty: United Offensive and Call of Duty 2 performing the roles of bomber escort and air superiority, respectively.

Call of Duty: United Offensive
In the single-player campaign of Call of Duty: United Offensive, Spitfires are seen in the level, "Bomber," acting as escort fighters for number ninety squadron of the RAF, a squadron flying the new American B-17 heavy bomber. These Spitfires help to fight off marauding Luftwaffe Bf 109s, but cannot accompany the squadron past the English Channel due to their limited range.

Call of Duty 2
In Call of Duty 2, the Spitfire is never seen up close but can be spotted dogfighting with German Ju 87s during the British North African campaign levels such as "The End of the Beginning" and "Assault on Matmata". The player can get a better view of the Spitfires at the conclusion of "The End of the Beginning": when rejoining Captain Price at the captured German FlaK 88s, Spitfires can be seen flying by in pairs, returning to base after having established air superiority.

Trivia

 * The portrayal of the Spitfire in Call of Duty: United Offensive is accurate from the standpoint of its limited range disallowing it to accompany the bombers past the English Channel. It wasn't until fighters such as the P-38 Lightning, the P-47 Thunderbolt, and especially the P-51 Mustang became widely available with drop tanks that fighters could accompany bombers through an entire mission into Germany.
