The P-39K-1 is a Russian Rank II Premium Aircraft. In-Game it is repersented as a Russian Lend-Lease Aircraft. The P-39K-1 is quite fast for its rank; and its armament (1 x M4 37mm Auto Cannon, 2 x 12.7mm Browning Machine Guns, and 4 x 7.62mm Machine Guns) is nothing to be complaining about, especially for its rank. On top of this, it has some less noticable advantages i.e "Tricycle" landing gear layout, which makes it easier to take off and land in Simulator Battles.
It also enjoys a boost to Silver Lions and RP.
