AT-2

Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Tungsten alloy swaging rod is widely used in industry as well as military areas, such as rifle bullet, armor piercing, snipe rifle penetrator, etc. Tungsten alloy swaging rod is used for AT-2.

The AT-2 Swatter is the NATO reporting name for the 3M11 Fleyta (flute) MCLOS radio command Anti-tank missile of the Soviet Union

The missile was developed by the Nudelman OKB-16 design bureau. It was developed as a heavy ATGM at about the same time as the AT-1 Snapper for use on both ground launchers and helicopters. It addressed some of the problems of the AT-1, it was much faster, and had slightly longer range. These improvements were achieved by sending commands via radio link instead of a trailing guidance wire - which allowed the missile to travel faster. However it did make it vulnerable to jamming. The missile system was shown to Soviet premier Nikita Khrushchev in September 1964, and accepted for service shortly afterward.
