La GBU-56 Mk-84 Laser JDAM es la configuración Laser JDAM de 2.000 libras de Boeing para la Mk 84 y cuerpos de bomba relacionados de 2.000 libras. Combina guiado JDAM GPS/INS con un buscador terminal láser para blancos móviles, reubicables y marítimos, mientras que material público de la Air Force y la Navy la sitúa en contextos de entrenamiento, producción y sustitución de penetradores de la Navy, más que en uso en conflicto documentado directamente.

Aeronaves portadoras

La evidencia pública de porte es más sólida para el F-15 y la actividad de pruebas del F-15E; estos enlaces evitan tratar el uso general de JDAM en combate como uso de la GBU-56 en conflicto.

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.

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.

Official U.S. sources describe its GPS/INS guidance, 2,115-pound launch-weight configuration, and 15-mile range class, while open-source munition and aviation reporting connect the BLU-109 GBU-31 JDAM lane to Israeli operations during 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.

U.S. Air Force sources list the GBU-38 at 92.6 inches long, 558 pounds at launch, a 14-inch wingspan, up to 15 miles range, and 5-meter-or-less CEP when GPS data is available, while combat reporting documents F-15E, F-16, B-1B, and MQ-9 employment in Afghanistan, Iraq, and 2014 Operation Inherent Resolve.

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.
