9K114 Shturm[2] (Russian: 9?114 «?????», lit.?'Assault') - is a SACLOS radio guided anti-tank missile system of the Soviet Union. Its GRAU designation is 9K114.[3] Its NATO reporting name is AT-6 Spiral. The missile itself is known as the 9M114 Kokon

The missile called 9M114 Kokon (Cocoon) was developed by the Kolomna Machine Design Bureau, which was also responsible for the 3M6 Shmel and 9M14 Malyutka. Work on the missile began in 1967, with the hope of using the missile on Mi-24s. However, delays forced the design of an upgraded Falanga system (9M17 Skorpion) using SACLOS guidance as a stopgap. Testing of the missile was completed in 1974, and it was accepted into service in 1976. The missile has no direct western counterpart; in role it is similar to the TOW and HOT missiles which entered service around the same time, though the Shturm has greater weight, speed, and range.

It was originally given the NATO designation AS-8, before being redesignated as AT-6
