Mk 82 500-pound unguided bomb

Also known as
  • Mk 82
  • Mk-82
  • Mark 82
  • 500 lb GP bomb
  • 500-pound GP bomb
  • LDGP bomb

The Mk 82 is the U.S. Mark 80-series 500-pound low-drag general-purpose bomb. Developed in the 1950s to reduce drag, it has been documented from Vietnam and Desert Storm through NATO's Kosovo air campaign, Operation Iraqi Freedom, Yemen, Gaza, and Marawi, and it remains important as both a free-fall bomb and the body for guided derivatives such as GBU-12 and GBU-38 JDAM.

Role in Conflicts

Side
United States and South Vietnam

Smithsonian National Air and Space Museum coverage documents U.S. Air Force F-100D Super Sabres in Vietnam carrying two 500-pound Mk 82 Snakeye high-drag bombs for in-country close-air-support missions and shows a 1966 F-100D dropping a Snakeye bomb on a suspected Viet Cong position.

Side
Israel

The Guardian reported on 2 July 2025 that ordnance experts identified fragments from the 30 June 2025 al-Baqa cafe strike in Gaza City as consistent with an MK-82 general-purpose bomb, while noting photo-based identification limits.

Role details
Side
Philippine government forces

Philippine Air Force OV-10 aircraft used 500-pound Mk 82 bombs during 2017 Battle of Marawi airstrikes against IS-aligned militant positions; later ordnance-clearing reports also identified unexploded 500-pound general-purpose bombs dropped by Philippine Air Force jets over Ground Zero during the siege.

Design Notes

The Mk 82 is the low-drag member of the Mark 80 family. It uses a relatively light bomb body to carry a large explosive charge, then changes delivery behavior through fuzes, fins, retarding kits, or guidance packages.

Bomb body

The U.S. Army describes the MK80 series as aerodynamically designed, relatively light general-purpose bomb bodies used in most bombing operations.

Target set

Army acquisition material describes MK82 as a 500-pound bomb for soft, fragment-sensitive targets such as troops, petroleum/oil/lubricant sites, and radars, not hard targets or penetrations.

Configuration options

The family can use nose and tail fuzes, conical or retarding fins, and laser/GPS guidance airfoil kits; BLU-111 and BLU-129 retain the 500-pound class while changing filler or casing effects.

Variants

Mk 82 designations often combine the same 500-pound low-drag bomb body with different fin, fuze, and guidance-kit packages. Retarded-fin configurations support low-altitude delivery, while GBU-12 and GBU-38 records cover laser-guided and GPS/INS-guided uses of the same weight class.
