GBU-32 1,000-pound Joint Direct Attack Munition

Also known as
  • GBU-32
  • GBU-32 JDAM
  • GBU-32(V)1/B
  • GBU-32(V)2/B
  • 1,000-pound JDAM
  • 1000-pound JDAM
  • Mk 83 JDAM

The GBU-32 1,000-pound Joint Direct Attack Munition is Boeing's GPS/INS JDAM guidance kit applied to the Mk 83 or BLU-110 1,000-pound bomb-body class. JDAM is a conversion kit rather than a stand-alone bomb, and the GBU-32 sits in the middle of the JDAM family between 500-pound and 2,000-pound variants. Direct conflict-use sources connect the GBU-32 to U.S. Navy, U.S. Air Force, and NATO-led coalition operations in Afghanistan, Iraq, Libya, and 2014 Operation Inherent Resolve, while OHCHR reported suspected Israeli use of GBU-32 bombs in Gaza strikes during the 2023 Israel-Hamas War.

Role in Conflicts

During the 2011 First Libyan Civil War, RAND's Libya air-campaign study identifies GBU-32 JDAMs among Italian precision munitions used by NATO-led coalition aircraft, including Tornado IDS strike loadouts and AV-8B attack sorties.

Variants

JDAM is a guidance-kit family applied to existing bomb bodies. The same 1,000-pound class can therefore appear as a standard GPS/INS JDAM, a Laser JDAM with terminal laser homing, or a JDAM-ER with a wing kit for longer-range glide attacks; adjacent 2,000-pound GBU-31 designations sit in the same JDAM family but use heavier bomb bodies.

Carrier Aircraft

The AV-8B Harrier II, Panavia Tornado, and F-35B are documented carrying the GBU-32 in strike loadouts. The same 1,000-pound JDAM tells a different story depending on the aircraft carrying it: stealthy internal carriage on a Raptor, carrier-deck loading on a Super Hornet, tactical strike from F-15E or F-16 units, and mass precision attack from bomber aircraft.

Bomb Body Compatibility

The GBU-32 designation sits on the 1,000-pound bomb-body class; nearby GBU designations now appear in the Variants section when they have their own catalog pages.

Designation Split

GBU-32 is easiest to read as a JDAM kit-and-bomb-body designation rather than a separate bomb design. Public sources place the main 1,000-pound class around Mk 83 and BLU-110 bomb bodies, with older Navy designation material separating the BLU-110 path before later GBU-32(V)2/B usage folded the 1,000-pound Navy naming together.
