The Dornier Do 26 was an all-metal gull winged flying boat produced before and during World War II by Dornier Flugzeugwerke of Germany.

It was operated by a crew of four and was intended to carry a payload of 500 kg (1,100 lb) or four passengers on the Lisbon to New York route.

Design and development

The elegant Do 26, sometimes referred to as the "most beautiful flying-boat ever built",[1] was of all-metal construction. The hull had a central keel and a defined step; the wings were of gull wing configuration, the outer sections being equipped with fully retractable narrow stabilising wing-floats, instead of Dornier's famous "water-wing" sponsons extending from the lower hull for lateral stabilization.

Its four engines, Junkers Jumo 205C diesels, were mounted in tractor/pusher pairs in tandem nacelles located at the joint between the dihedral and horizontal wing sections. The rear (pusher) engines could be swung upwards through 10° during take-off and landing, to prevent contact between the three-blade airscrew and water spray created by the forward propellers.

The tail unit was of conventional design, comprising a horizontal tailplane and a single, vertical fin with rudder.

Operational history


In 1937, Deutsche Lufthansa ordered three Do 26 aircraft, which were designed to be launched by catapult from special supply ships, for transatlantic air mail purposes. The first, Do 26 A D-AGNT V1 Seeadler ("Sea eagle"), was piloted on its maiden flight by Flight Captain Erich Gundermann on 21 May 1938; D-AWDS V2 Seefalke ("Sea Falcon"), followed on 23 November 1938, piloted by Flight Captain Egon Fath. Both were completed and handed over to Deutsche Lufthansa before the outbreak of World War II. Due to opposition from the United States, the German airline was unable to operate these aircraft on the intended transatlantic route; instead, in 1939 they were used to carry air mail between Bathurst and Natal in South Africa. The third aircraft, Do 26 B D-ASRA Seemöwe ("Seagull") was completed shortly before the start of World War II.

One notable Do 26 civilian mission was carried out by V2 Seefalke, when on 14 February 1939 the veteran Lufthansa pilot Flight Captain Siegfried Graf Schack von Wittenau embarked on a mercy flight to Chile, taking 580 kg (1,279 lb) of medical supplies for earthquake victims in Chile. The 10,700 km (6,600 mi) flight lasted 36 hours.[1]

World War II

All three Deutsche Lufthansa aircraft were impressed into military service in 1939 at the outbreak of World War II, as P5+AH, P5+BH and P5+CH respectively.[2]

Three other Do 26 aircraft (V4 - V6) were built as Do 26 C for the Luftwaffe with the more powerful 648 kW (880 hp) Junkers Jumo 205D engines; the original three aircraft were similarly converted for military service. Armament consisted of one 20 mm MG 151/20 cannon and three 7.92 mm (.312 in) MG 15 machine guns.

Norwegian Campaign

The Do 26s saw service in April and May 1940 in the Norwegian Campaign, transporting supplies, troops and wounded to and from the isolated German forces fighting at Narvik under the command of General Eduard Dietl. During this campaign three of them were lost:

On 8 May 1940, V2 (ex Seefalke)[3] was shot down by three Blackburn Skuas of 803 Naval Air Squadron, Fleet Air Arm, operating from the Royal Navy aircraft carrier HMS Ark Royal[4] while carrying 18 Gebirgsjägers to the Narvik front.[3] After a running fight V2 crash-landed in Efjorden in Ballangen. Siegfried Graf Schack von Wittenau, the crew and 18 soldiers, were captured in bloody fighting with Norwegian forces.[3] One of the Skuas, flown by future Fleet Air Arm fighter ace Sub-Lieutenant Philip Noel Charlton,[5] was hit by return fire from V2 and made an emergency landing at Tovik near Harstad.[3]

Then, on 28 May 1940, both V1 (ex Seeadler) and V3 (ex Seemöwe) were set ablaze with gunfire and sunk at their moorings at Sildvik in Rombaksfjord near Narvik,[6] when discovered and attacked by three Hawker Hurricanes of No. 46 Squadron RAF led by the New Zealander Flight Lieutenant (later Group Captain) P.G. "Pat" Jameson,[6] DSO, DFC and bar[7] shortly after landing.[6] Three gunss destined for the German forces fighting in the mountains east of Narvik were lost with the destruction of V1 and V3,[8] whilst one gun was recovered from one of the aircraft before it was lost.[6]

Later World War II service

V5 was lost on 16 November 1940, killing its crew, after being launched at night from the catapult ship Friesenland[9] in Brest, France. The fate of V4 and V6, which in 1944 were still assigned to the Test Unit (German: Erprobungsstelle) in Travemünde, is unclear.[10]


Do 26A
Two prototypes, named V1 (D-AGNT Seeadler) and V2 (D-AWDS Seefalke).
Do 26B
Third prototype, named V3 (D-ASRA Seemöwe).
Do 26C
Military variant for Luftwaffe, powered by Junkers Jumo 205D engines and armed with one 20 mm MG 151/20 cannon and three 7.92 mm (.312 in) MG 15 machine guns. Three aircraft built. V1, V2 and V3 were rebuilt to similar standard.


  • Deutsche Lufthansa operated two Do 26A and one Do 26B between 1938 and 1939. Later all three were handed over to the Luftwaffe.
  • Luftwaffe operated all six built aircraft.
    • Erprobungsstelle Travemünde
    • KGr.z.b.V. 108 (operated in Trans-Ozean Staffel/KGr.z.b.V. 108)[11]
    • Küstenfliegergruppe 406 (operated in Sonderstaffel/Ku.Fl.Gr.406)[12]


The wrecks of V1 Seeadler and V3 Seemöwe were located in Norwegian waters off Narvik after the war. Seemöwe has been removed but the fuselage and wings of Seeadler remain in situ (and are an attraction for divers). Some components from Seeadler, including the cockpit instrument panel and a propeller, are on display at the Narvik War Museum; another propeller can be seen at the flying club in Bodø, Norway.[13]
