Direct Attack Weapons
General Purpose (GP) bombs are free-fall ordnance. The bombs are only as accurate as the pilot or platform delivering them. The primary weapons effects are due to blast and fragmentation. They come in a variety of sizes and weights ranging from 500 pounds for BLU-111/MK-82, 1000 pounds for the BLU-110/MK-83, and 2,000 pounds for the BLU-117/MK-84.
Joint Direct Attack Munition (JDAM) is attained by adding a guidance kit to an existing unguided bomb thus converting it into precision-guided "smart" munitions. It improves the accuracy of the bombs in any weather condition and can be employed from Navy and Marine Corps fighter-attack aircraft. JDAM features GPS/INS combined with a tail control system for guidance. JDAM enables multiple weapons to be directed against single or multiple targets on a single pass.
Laser JDAM is a Global Positioning System (GPS) aided Inertial Navigation System (INS) and Laser-guided direct attack weapon, capable of precision guidance and attack of stationary targets through the weather, as well as reactive targeting and attack of stationary and moving maneuvering targets in clear weather.
Direct Attack Moving Target Capability (DAMTC) is a program that combines existing precision strike weapons capabilities to bring advanced GPS/INS, and laser technology together as a system-of-systems to effectively neutralize stationary and moving/maneuvering time-sensitive targets of opportunity day, night and through the weather in any operational environment.
Laser-Guided Bomb (LGB) units are configured to detect and track a target illuminated by a laser. The GBU-12 utilizes a 500-pound general-purpose warhead and is a member of the Paveway II series of LGBs. The GBU-16 consists of a 1,000-pound bomb modified with a common Paveway II laser guidance kit. The GBU-10 utilizes the 2,000-pound general purpose bomb. The GBU-24 consists of a 2000-pound BLU series bomb body and is designated as a hard target penetrator.
The Dual-Mode Laser-Guided Bomb (DMLGB) is a modified LGB converted to the dual-mode configuration using common components. It provides increased flexibility by combining proven technology of laser terminal guidance with all-weather, fire-and-forget capability and GPS/INS.
The Low Collateral Damage Bomb (LOCO) was developed by the Navy to deliver ordnance to urban targets with reduced collateral damage in situations where friendly forces and/or civilians are close to the target.
Fuzes are safety devices that preclude inadvertent initiation of munitions until a safe separation distance from the launch platform is attained and a predetermined function point or time occurs. The FMU-139 is an electronic tail fuze used in general purpose bombs. The FMU-143 is an electronic tail fuze used in penetrator warheads. The Hard Target Void Sensing Fuze (HTVSF) provides in-cockpit reprogramming capability with fuze time delay options affording the aircrew the ability to detonate penetrating bombs at various levels within multi-story target facilities.
