Technical Description (German Edition)
Mid wing cantilever monoplane in three portions, comprising a rectangular centre-section built integral with the fuselage and two tapering outer sections. Wing is designed to give temporary flotation in event of ditching. Structure of light metal consisting of two spars and the usual number of ribs, the whole covered with a stressed skin of smooth duralumin sheet. All-metal ailerons, each incorporating a spring and trim tab. Fowler type all metal in-board and out-board trailing edge flaps. All metal two section spoilers in upper surface of outer wing panels inboard of ailerons. Thermal de-icing of leading edges.

Fuselage of conventional unpressurised semi-monocoque construction. Main structure is built up of a number of formers and stringers to which the stressed skin is riveted.

Cantilever all-metal tail unit. Spring tab and trim tab in rudder, balance tab and spring tab in each elevator. Tail unit has thermal de-icing of all leading edges.

Retractable tricycle-type undercarriage with single steerable nosewheel and twin-wheel main units. Hydraulic retraction, nosewheel rearward, main wheels forward into engine nacelles.

Two Bramo 328F eighteen-cylinder radial engines each rated for 3,200 hp at takeoff. Three-bladed VDM controllable pitch full-feathering airscrews. Self-sealing fuel tanks in wings. Oil tanks in engine nacelles behind engines.

Crew of eight. The station for one wireless operator/air gunner is located in the nose of the aircraft; cockpit for the pilot and observer follows; the flight engineer’s station is located behind and below the cockpit, with the navigator. Two stations are provided for electronic equipment operators while a final station is provided in the rear of the aircraft for the second wireless operator/air gunner. Two twin 15mm MG151 machineguns with 250 rounds per gun located in the forward gunner’s position and two similar weapons in the tail gunner’s position. Internal bomb cell for up to 4,000 kg of free-fall bombs, depth charges, torpedoes or other ordnance. External mounts for additional ordnance or auxiliary fuel tanks. Equipment includes long and short wave transmitting and receiving sets, direction-finding loop, blind approach receiver and airborne electronic detection equipment.

Technical Description (French Edition)
France ordered a significant quantity of Dornier Do330s in order to equip several surveillance squadrons of the Aeronavale. No significant changes were made to the airframe itself. Serious consideration was given to replacing the Bramo engines with a French-sourced alternative, but the Aeronavale eventually decided to stick with the original engines.

The greatest difference came in the electronics, which were entirely of French design and manufacture, and included the SDA-8 Vexin radio-teledetector set in a small fiberglass-covered ventral dome.
