always_keeps_gun: true description: "The BF 109 series was, along with the Focke-Wulf Fw 190, the backbone\ \ of the Luftwaffe's fighter force. The Bf 109 first saw operational service in\ \ 1937 during the Spanish Civil War and was still in service at the dawn of the\ \ jet age at the end of World War II in 1945. The final production version of the\ \ Bf 109 was the K series or Kurf\xFCrst, introduced in late 1944, powered by the\ \ DB 605D engine with up to 2,000 PS (1,973 HP). Though externally akin to the late\ \ production Bf 109G series, a large number of internal changes and aerodynamic\ \ improvements were incorporated that improved its effectiveness and remedied flaws,\ \ keeping it competitive with the latest Allied and Soviet fighters. The Bf 109's\ \ outstanding rate of climb was superior to many Allied adversaries including the\ \ P-51D Mustang, Spitfire Mk. XIV and Hawker Tempest Mk. V." introduced: 1944 manufacturer: Messerschmitt price: 4 role: Fighter gunfighter: true variants: "Bf 109 K-4 Kurf\xFCrst": {}
