The Yak-6 was a small, light twin-engined plane built from non-strategic materials and designed to carry four passengers, 2,200 lbs of cargo or a combination of the two. With the addition of external racks for five 220 lbs or ten RS-82 rockets, it was used for night bombing and ground support. It also saw service as an air ambulance and glider tug. The Yak-6 was frequently used to resupply partisans and by 1944 many partisan camps had a Yak-6 available.
Some 1,000 Yak-6's of all types were built. The plane burns 10.1 gallons of fuel per hour at routine usage.

Design Notes
Design aSpeed is 126 mph; the historical speed, as well as actual wing
area (319 sf), has been used.
As the plane was primarily constructed out of wood, the armor was bought with the Wooden option.
To lower unloaded weight to the historical number, the chassis, wings and engine pods had their cost, weight and HPs reduced by half. Even so, weight still had to be reduced a further 17%. Historical maximum take-off weight is 5,500 lbs.
Variants
The initial Yak-6 used 104-kW engines, which lowered speed to 138 mph.
The Yak-6 NBB was the night bomber version, armed with five external 220-lb bombs or ten RS-82 rockets. Many also carried a simple open mount machinegun (7.62mm ShKAS) on the roof behind the crew cabin.
The Yak-8 was to have been a larger plane, with room for six passengers. However, the more powerful engines required did not appear and the project was scrapped.
