The Caspar U.1 (sometimes knows 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 7.40m long with a diameter of 1.70m, 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 55hp (41Kw) 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]
