The Douglas Cloudster II was an American prototype five-seat light aircraft of the late 1940s.

During the early 1940s, Douglas Aircraft Company developed a configuration for high-performance twin-engined aircraft, in which the engines were buried in the fuselage, driving propellers mounted behind a conventional tailplane, in order to reduce drag by eliminating drag inducing objects such as engines from the wing.

[1][2] Owing to the initial success of the XB-42, Douglas adopted this promising new layout for a medium-range airliner, the DC-8[3] and a five-seat light aircraft suitable for executive or air charter use, the Model 1015 or Cloudster II.

The pilot and four passengers sat in an enclosed cabin well ahead of the unswept, laminar flow wing.

Two air-cooled piston engines were buried in the rear fuselage, driving a single eight foot diameter twin-bladed propeller, mounted behind the empennage via driveshafts taken from P-39 fighters.
