The Edo OSE was a 1940s American single-seat multi-role floatplane designed and manufactured by the Edo Aircraft Corporation.

Design and development[edit]

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.

Variants[edit]

XS2E-1

Original designation for OSE and TE single seat floatplane scouts.

XOSE-1

Prototypes and production single-seat aircraft redesignated from XS2E-1; eight built.

XOSE-2

Prototype two-seat floatplane scout aircraft, two converted from XOSE-1.

OSE-2

Production two-seat floatplane scout aircraft, four aircraft were assigned Bureau of Aeronautics numbers (BuNos.), but production was cancelled.

XSO2E-1

Original designation for XTE-1 conversions.

XTE-1

Two-seat floatplane trainer conversions, two aircraft converted from the XOSE-1 prototypes.

TE-2

Developed from the TE-1, four aircraft were assigned BuNos., but production was cancelled.
