The Dornier Seastar is a turboprop-powered amphibious aircraft built largely of composite materials. Developed by Claudius Dornier Jr (de) of Germany, it first flew in 1984. The design is owned by Claudius Jr's son, Conrado, who founded Dornier Seawings AG (now Dornier Seaplane Company) to continue work on the project.

Design and development[edit]

The Seastar is a parasol wing flying boat, with its two engines mounted in a single nacelle over the wings in a push-pull configuration. In general layout, it strongly resembles both the innovative Dornier Wal all-metal monoplane flying boat of the 1920s, of which over 250 examples were built; and its direct successor, the larger Dornier Flugzeugwerke's Do 18 of the 1930s.

The first prototype, a proof-of-concept aircraft using the metal wings from a Dornier Do 28 and with large struts bracing the wing to the sponsons, made its maiden flight from Hamburg on 17 August 1984.[1] The second prototype, representing the definitive design was larger, and featured a new composite wing, connected with a set of cabane struts to the fuselage only. It first flew from Oberpfaffenhofen on 24 April 1987.[1]

In October 2009, Dornier Seaplane announced that it would launch production of the Seastar.[2]

In May 2010, Dornier Seaplane announced that it would build the Seastar in Saint-Jean-sur-Richelieu, about half an hour away from Montreal, Quebec, Canada.[3]

The company has since become a joint venture involving two Chinese state owned companies and plans to produce the aircraft in two locations, with one site in Oberpfaffenhofen, Germany and another in Wuxi, China.[4]

In January 2016, Dornier Seaplane announced that Seastar airframes would be built by Diamond Aircraft Industries.[5]
