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 CBU-87.
The CBU-87 Combined Effects Munition is a cluster bomb used by the United States Air Force, developed by Aerojet General/Honeywell and introduced in 1986 to replace the earlier cluster bombs used in the Vietnam War. CBU stands for Cluster Bomb Unit. When the CBU-87 is used in conjunction with the Wind Corrected Munitions Dispenser (WCMD) guidance tail kit, it becomes a precision-guided weapon, designated CBU-103.
The CBU-87 without WCMD is designed to be dropped from an aircraft at any altitude and any air speed. It is a free-falling bomb and relies on the aircraft to aim it before it drops; once dropped it needs no further instruction, as opposed to guided munitions or smart bombs. The bomb can be dropped by a variety of modern-day aircraft. It is 7 feet, 7 inches (2.33 meters) long, has a diameter of 16 inches (40 centimeters), and weighs roughly 950 pounds (430 kg). The price is US$14,000 per bomb.
Each CBU-87 consists of an SUU-65B canister, a fuse with 12 time selections and 202 submunitions (or bomblets) designated BLU-97/B Combined Effects Bomb (CEB). Each bomblet is a yellow cylinder with a length of 20 centimeters and a diameter of 6 centimeters. The BLU-97/B bomblets are designed to be used against armour, personnel and softskin targets and consist of a shaped charge, a scored steel fragmentation case and a zirconium ring for incendiary effects. The CBU-87 can also be equipped with an optional FZU-39/B proximity sensor with 10 altitude selections.
