Design and development

The Edo Aircraft Corporation was an established company that produced seaplane floats. In 1946, Edo designed its first aircraft, the Edo OSE. Two prototype aircraft (designated XOSE-1) were built and flown in 1946. The XOSE-1 was a single-seat low-wing cantilever monoplane with a single float and fixed wingtip stabilizing floats. The wings could be folded for shipboard storage. The aircraft was designed for a variety of roles including observation and anti-submarine patrols. Unusually, it was designed to carry a rescue cell on the underwing hardpoints, which would be capable of carrying a single person when used for air-sea rescue. Eight production aircraft (designated XOSE-1) were built to a United States Navy order but none were accepted into service. A two-seat training conversion was carried out as the XTE-1, but production TE-2 aircraft were cancelled.

gollark: But wrong.
gollark: It's relativistic apioids.
gollark: ↓ my response
gollark: This actually fits into an 80-bit floating point with an extra 0.7 bits left over. How convenient!
gollark: It's very efficient.
