790 Nautilus
Role Coastal patrol flying-boat
National origin France
Manufacturer Breguet Aviation
First flight 1939
Number built 2

The Breguet 790 Nautilus was a prototype French three-seat coastal patrol flying-boat designed and built by Breguet Aviation to meet a requirement from the French navy.[1]

Development

The Nautilus had a high-set monoplane wing on a single-step hull, the wing was fabric covered and the hull all-metal.[1] The aircraft was powered by a 720 hp (537 kW) Hispano-Suiza 12Xirs V-12 piston engine strut mounted above the hull driving a pusher propeller.[1]

The first of two prototypes flew in 1939 and performed well enough that a production order for 75 was placed.[1] The order was reduced to 45 in May 1940 in order to free production capacity for more urgently needed combat aircraft, but none were built following the German invasion.[1][2]

Variants

Breguet 790
Basic three-seat coastal reconnaissance aircraft, powered by 540 kW (720 hp) Hispano-Suiza 12Xirs engine. Two prototypes built.[3]
Breguet 791
Proposed version powered by single 490 kW (660 hp) Gnome-Rhône 14M radial engine. Unbuilt.[2]
Breguet 792
Proposed version for ship-based reconnaissance aircraft, powered by two 270 kW (360 hp) Béarn 6 air cooled inline engines. Unbuilt.[2]
