YJ-83

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 YJ-83.

The Yingji-83 (or YJ-83 - Chinese: 鹰击-83, literally "Eagle Strike") is a Chinese anti-ship missile based on the earlier YJ-82 model of the same class. It was designed as a supersonic successor to the subsonic YJ-82. The weapon's export designation is C-803.

The chief designer for the YJ-83 and the YJ-85 (the latest member of the YJ-8 series) is Huang Ruisong (黄锐松), who succeeded Liang Shoupan (梁守槃) upon his retirement. Ruisong designed the YJ-83 to have an operational range of over 255 km when launched from the air and roughly 150 to 200 km when surface-launched. The YJ-83 anti-ship missile appeared in the National Day parade for the first time in 1999, and was only armed with a radar seeker. Seekers for the YJ-82/C-802 upgrade are also available for the YJ-83/C-803, but it is not yet clear if the Chinese have adopted these seekers. The launching and storage unit of the new missile retained the capability to handle earlier missiles, including the CY-1 ASW missile.
