VL Kotka

VL Kotka on Tikkakoski airport in March 1940.

VL E.30 Kotka, KA-147, in Vesivehma in 2006

VL Kotka ("Eagle") was a Finnish two-seat, biplane maritime patrol aircraft, designed and built by the Valtion lentokonetehdas or VL ("State Aircraft Factory"). It was meant as a cheaper replacement (compared to the Blackburn Ripon) for the outdated IVL A.22 Hansas that were in service with the Finnish Air Force.^[1]

The prototype made its first flight on September 30, 1930. In 1931, the State Aircraft Factory began production of a series of five aircraft. These were used as liaison aircraft until 1944.^[2]

One aircraft (KA-147) is on display at the Päijät-Häme Aviation Museum.^[3]

Versions
