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 has been widely used for GBU-15.
Guided Bomb Unit 15 is an unpowered, glide weapon used to destroy high-value enemy targets. It was designed for use with F-15E Strike Eagle, F-111 'Aardvark' and F-4 Phantom II aircraft, but the United States Air Force is currently only deploying it from the F-15E. The GBU-15 has long-range maritime anti-ship capability with the B-52 Stratofortress. Rockwell International is the prime contractor for this weapon system.
The weapon consists of modular components that are attached to either a general purpose Mark 84 bomb or a penetrating-warhead BLU-109 bomb. Each weapon has five components—a forward guidance section, warhead adapter section, control module, airfoil components, and a weapon data link.
The guidance section is attached to the nose of the weapon and contains either a television guidance system for daytime or an imaging infrared system for night or limited, adverse weather operations. A data link in the tail section sends guidance updates to the control aircraft that enables the weapon systems operator to guide the bomb by remote control to its target.
