The VL Humu (Whirlwind) is a Finnish fighter aircraft, designed by Valtion lentokonetehdas in 1944, and based on the American Brewster F2A Buffalo.

[1] The Finnish Air Force had acquired 40+ surplus B-239 naval variants of the Brewster Buffalo and put them to good use during the Winter War, so it was decided in 1942 to produce a copy due to aircraft shortages.

[2] The Humu was largely constructed out of wood due to scarcity of metals, but the frame was made from steel and its design followed closely that of the Brewster.

The wooden wing added 250 kg of extra weight and moving the fuels tanks from the wing to the aft fuselage adversely affected maneuverability due to the center of gravity being shifted.
