Vympel K-13 (missile)

The first significant produced Soviet air-to-air missile, the Vympel K-13, NATO code name AA-2 ATOLL, was reverse-engineered from an AIM-9B Sidewinder obtained by China. When it became operational in 1960, the first Soviet version was also known as the R3-S.

There were a few upgrades, but the series never went farther than a early Sidewinder equivalent, before the Soviets went to an original design.
