Berliner-Joyce
OJ-2
Designed in 1930 to meet a USN
requirement for an observation biplane, the OJ-2 had a very brief two-year
service record from 1933-1935. The
plane was able to be catapult launched, and some planes were fitted with a
center-line fuselage float and two wing floats in place of wheeled landing
gear. The forward MG was fitted to the
upper starboard wing, while the observer had a trainable MG. Ordnance was carried on three hardpoints
under the wings and fuselage. Some
planes were used as late as 1940 in the Naval Reserves. A total of 39 planes were received by the
USN.

Design
Notes:
Historical wing area was 284 sf. Design loaded weight was 3,757 lbs.; it was
increased 1% to the historical. Design
aSpeed was 154 mph with loaded hardpoints.
Historical values were used for all calculations when available. Fuel capacity was based on a rough
calculation between range (530 miles) at cruising speed and design fuel
consumption. MG load-outs are a
guess. Adding floats to the design (one
Medium Weapon pod and two Mini Weapon pods) increases design weight by 866
lbs.; wSpeed is 60% of stall speed, requiring calm waters and a slight tailwind
to get airborne.
Variants:
The XOJ-1 prototype featured a 224-kW
engine.
The XOJ-3 had a cockpit canopy. It crashed in March 1934 and was rebuilt as
a standard OJ-2.
