The Avro Shackleton is the final military version of the venerated Lancaster series of bombers. Developed in 1945 from the now-obsolete Avro Lincoln as an anti-submarine warfare (ASW) and maritime patrol aircraft, the Shackleton featured more specialized armaments, such as a naval radar housed inside a distinctive "bulge" on the belly of the aircraft. The tail gunner position is removed in favour of a flexible mount with 20 mm Hispano Mk.V autocannons to strafe naval targets. The plane also features more efficient Rolls-Royce Griffon engines powering contra-rotating propellers.

Introduced in Update "Direct Hit", the Shackleton MR.Mk.2 can be best described as a "quirky" version of the Lincoln B Mk II, with overall better mobility and payload, but worse defensive coverage and survivability. The plane has access to some of the most efficient payloads available, being capable of taking out 3 bases with its maximum bomb loadout. Due to its powerful Griffon engines, the Shackleton can be played either as a traditional long range bomber by using its decent climb rate or as a fast bomber using its high WEP power.
