In 1925, the Danish government was in the midst of a modernisation programme for the nation’s fledgling Royal Naval Air Service, which had been established in 1923.
Keen to garner sales with foreign air arms, H.G. Hawker demonstrated its Hawker Woodcock II single-seat fighter to the Danes, who were impressed enough to order three similar machines, the Hawker Woodcock II’s with the Bristol Jupiter engine being replaced by an Armstrong Siddeley Jaguar.
Part of the deal also stipulated other minor modifications, the result saw the aircraft designated the Hawker Danecock. The deal arranged for 12 more examples to be built under licence at the Danish Royal Navy Dockyard in Copenhagen, these to be known as L.B.II Dankoks.
Under the supervision of Hawker designer Sydney Camm, the standard Hawker Woodcock II was modified with a slightly lengthened fuselage, an extra inch (25mm) on the span and a reduction in the span of the lower wing.
On December 15th, 1925, Hawker test pilot P.W.S. 'George' Bulman took the Danecock prototype (serial 151), aloft at Brooklands for its maiden flight, the other two examples (serials 152 and 153) following it into the air within a month.
Working to a very tight schedule, H.G. Hawker nevertheless managed to test, pack and ship the aircraft to Copenhagen some five weeks before they were due to make their first flights.
Furthermore, the structural weight of the finished machines was found to be below the guaranteed figure, despite increases in equipment, and the aircrafts’ performance as also in excess of that stipulated in the contract.
With the three Hawker Danecocks having arrived in Copenhagen in February 1926, work began on the licence-built Dankoks. All 12 of these (serials 154–165) were completed over the following 18 months and entered service with the Danish Navy’s No 2 Luftflotille and one with the Danish Army Air Service squadron.
One of the Hawker-built Danecocks achieved a Scandinavian altitude record of 28,208ft (8,598m) in January 1927, and the type continued to provide excellent service until 1937, when the type was retired.
One of the Hawker Danecocks (serial 158) survives today and is on display at the Danmarks Flymuseum at Stauning in western Denmark.
