powered by two 430 hp Lorrain 9N engines,never completed
CAO.500 was a single seat low-wing float seaplane fighter Project,took many components of CAO.200,powered
by one Hispano-Suiza 12Y or 12 X engine,in HC.1 tender
CAO.600 was a three-seat high inverted gull wing torpedo bomber and recce monoplane,had a twin tail fin,

CAO.700 was a five-seat mid-wing heavy bomber monoplane,of all-metal construction and twin tail fin,powered
by four 1140 hp Gnome-Rhone 14N-48 or N-49 engines,prototype
CAO.700M was torpedo bomber Project version,powered by the same engines,and could carry two torpedo
CAO.710 was a second prototype,powered by four 1320 hp Gnome-Rhone 14 R-2/3 engine,but these engines
must drive more propellers large diameter,had to extend the wingspan and increase the wing area,soon
CAO.720 was a low-wing 22 passenger medium transport/airliner monoplane,had a single-tail fin and the
fuselage was of circular section,the aircraft was to cross at 8,000 m,about 50 % completed but cancelled
in 1940
CAO.800 was a two-seat low-mid-wing dive bomber monoplane Project,in BP.2 category,had twin tail fin,powered
by one 890 hp Hispano-Suiza 12 Y engine,based on LN-411
CAO.810 was developed from CAO.800,the shape of tailplane monoplane biderive,it is characterized by a fuselage
in the shape of a camel's back,this shape was because the bombs were carried in the hold and the cockpit was
raised to improve the pilot's visibility,estimated speed of 535 km/h,powered by the same engine as above
CAO.900 was a 18 passenger transport amphibian flying boat monoplane Project,had a hull aircraft topped with a
monoplane wing attached to the fuselage by a hut,the wing had a part rectangular central which carried both
650 hp Gnome-Rhône 14 M engines placed at the leading edge, and parts trapezoidal external,these external parlies wore balancing balloons
