History
First flight1922

The Caspar U.1 (also referred to as the Caspar-Heinkel U.1) was a German patrol floatplane of the 1920s, designed by Ernst Heinkel and built by Caspar-Werke. [1] It was intended to be disassembled and stored inside a cylindrical container for transport aboard a submarine, from which it could be quickly assembled and launched. [1]

Development

The U.1 was designed to meet a requirement for an aircraft that could be stored inside a cylindrical container 7.40 metres (24.3 ft) long with a diameter of 1.70 m (5 ft 7 in); this would allow it to be carried aboard a submarine. [1] To reduce the time needed for assembly and launch, it was built as a cantilever biplane, eliminating the need to rig struts and wires during erection. [1] The aircraft was fitted with two single-step floats and powered by a front-mounted 55 horsepower (41 kW) Siemens radial piston engine. [1] The pilot sat in an open cockpit positioned behind the upper wing, providing an unobstructed forward view. [1] It was claimed that, during tests, four men were able to remove the U.1 from its container and assemble it in just 1 minute and 3 seconds. [1]

Two aircraft were purchased by the United States Navy for evaluation. [1] They were delivered to Naval Air Station Anacostia in late 1922 and tested during 1923. One of the aircraft was damaged beyond repair while mounted on a truck for a parade. [2]
