The record breaking SEV-3
amphibian as it appeared at Wright Field in the summer of
The first design
was manufactured under contract by Edo Aircraft Corporation
of College Point, Long Island, NY. Designed as a low wing
monoplane design, this first aircraft, designated the SEV-3,
was a floatplane. Edo, being the leading manufacturer of
aircraft floats, was an ideal choice when one considers that
Seversky had no manufacturing facilities. Even with Edo’s
expertise, construction still took two years, largely due to
the lack of capital funds.
Finally, in June of
1933, the SEV-3 took off from Long Island waters with
Seversky at its controls. Painted in a stunning bronze, the
SEV-3 was one of the more advanced aircraft in the world.
Several months later and fitted with a more powerful engine,
the SEV-3 set a new world speed record for amphibians. One
major contributor to the plane’s excellent speed was its
distinctive thin, but broad semi-elliptical wing. This basic
wing design would still be seen on the P-47 a decade later.
