The Caspar U.1 (sometimes known as the Caspar-Heinkel U.1) was a 1920s German patrol seaplane designed by Ernst Heinkel and built by Caspar-Werke. [1] The U.1 was designed to fit into a cylindrical container to allow it to be carried, then launched from a submarine. [1]
The U.1 was designed to meet a requirement to fit inside a cylindrical container 7.40 metres (24.3 ft) long with a diameter of 1.70 m (5 ft 7 in); this allowed the aircraft to be carried by a submarine. [1] To reduce the time to launch the aircraft, it was built as a cantilever biplane to remove the need to rig struts and wires on assembly. [1] The U.1 had two single-step floats and was powered by a front-mounted 55-horsepower (41 kW) Siemens radial piston engine. [1] The pilot had an open cockpit behind the upper wing which gave a clear view forward. [1] It is claimed that during tests, four men could remove the U.1 from the container and erect it in 1 minute 3 seconds. [1] Two aircraft were bought by the United States Navy for evaluation; [1] these were delivered to Naval Air Station Anacostia in late 1922, and were tested during 1923; one of the aircraft was damaged beyond repair whilst mounted on a truck for a parade.
