It was intended to be an aircraft that could be used for a variety of tasks including transport "mobile office" but only one prototype was built being scrapped in 1950.
The Aerocar was a high-wing monoplane with gondola fuselage and twin-boom tailplane and tricycle undercarriage.
The manufacturer claimed that as well as taking off in 160 yards on (dry) grass, it could climb on one engine at full load at 230 ft/min (70 m/min).

With the uncertainty arising from the partition of India in 1947, this became unlikely and Portsmouth Aviation was unable to continue with development.
