Official Air Force, Navy, Boeing, and security-assistance sources separate this KMU-556/Mk 84 configuration from BLU-109 penetrator GBU-31 variants, while direct records document exact or Mk 84-specific GBU-31 use in the 2011 Libya air campaign and the 2025 Israel-Iran Conflict.

U.S. military and Federal Register sources distinguish the KMU-556 Mk 84 configuration from the KMU-557 BLU-109 configuration, while direct conflict-use reporting traces GBU-31/JDAM employment from Kosovo and Afghanistan to Iraq, Yemen, Operation Inherent Resolve, the Israel-Hamas war, and the 2025 Israel-Iran conflict.
Joint Direct Attack Munition (JDAM) guidance kit, GPS/INS guidance tail kit for free-fall bombs, MunitionsMunitionsJoint Direct Attack Munition (JDAM) guidance kitGPS/INS guidance tail kit for free-fall bombsJoint Direct Attack Munition (JDAM) is Boeing's U.S.-origin GPS/INS tail-kit family for converting compatible Mk 80- and BLU-series free-fall bomb bodies into all-weather guided bombs. The family spans 500-, 1,000-, and 2,000-pound bomb-body classes, with standard GBU-31, GBU-32, and GBU-38 records separated from later Laser JDAM and JDAM-ER derivatives. Official Air Force and Navy records document JDAM's 1999 combat debut with NATO B-2 operations during Operation Allied Force.
BLU-109 penetrator warhead, 2,000-pound hard-target penetrator warhead, MunitionsMunitionsBLU-109 penetrator warhead2,000-pound hard-target penetrator warheadThe BLU-109 is a U.S.-origin 2,000-pound hard-target penetrator warhead built around a thick forged-steel bomb body for defeating reinforced structures and buried targets. It appears as the bomb body inside guided weapons such as GBU-24 Paveway III and GBU-31 JDAM configurations, with source-backed conflict context ranging from Saudi-led coalition stocks in Yemen to Israeli JDAM-linked use and transfers in Gaza, Lebanon, and the 2025 Israel-Iran fighting.

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.

Public sources describe the Laser JDAM concept as a Boeing GPS/INS JDAM fitted with a laser terminal seeker for moving or relocatable targets, while designation references treat GBU-55 as the 1,000-pound member between the 500-pound GBU-54 and 2,000-pound GBU-56 Laser JDAMs.
