Also known as
  • GBU-63
  • GBU-63/B
  • GBU-63 JDAM-ER

  • Mk 83 JDAM-ER

The GBU-63 JDAM-ER is a commonly reported but not fully confirmed 1,000-pound-class JDAM-ER designation associated with the Mk 83 / BLU-110 bomb-body class. It sits between the standard GBU-32 JDAM and the wider Boeing-Australian JDAM-ER wing-kit family, whose deployable wings turn GPS/INS JDAM bombs into longer-range glide weapons.

Variants

JDAM-ER naming is complicated by overlapping bomb-body and Quickstrike mine designations. GBU-63 is treated as a reported 1,000-pound JDAM-ER designation until a source directly confirms the exact operational weapon designation.

Air Force material places the standard GBU-32 1,000-pound JDAM in the Mk 83 / BLU-110 bomb-body class; the reported GBU-63 applies the JDAM-ER wing-kit concept to that weight class.

Boeing's 2015 RAAF test release documents the 500-pound JDAM-ER wing-kit family, and separate conflict-use sources document Mk-82 JDAM-ER use in Ukrainian service.

GBU-64/B2,000-pound Quickstrike-ER designation

Designation-Systems lists GBU-64/B as a 2,000-pound Mk 64 Quickstrike mine with a JDAM-ER guidance kit, which helps explain why GBU-63 remains a designation caveat rather than a fully confirmed bomb designation.

JDAM Family Context

The most useful sourced context for GBU-63 is its place among the 1,000-pound bomb-body class and adjacent JDAM/JDAM-ER family members.

The Mk-82 JDAM-ER entry covers the directly documented 500-pound wing-kit family; its Boeing/RAAF development evidence supports the JDAM-ER technology context without proving GBU-63 combat use.

Source boundary

Open reporting has described a 1,000-pound JDAM-ER in Ukrainian use, but the same reporting says the designation is unknown and only likely GBU-63. That is not enough to support a direct 2014 Russia-Ukraine War use claim for this designation.

Designation Notes

The GBU-63 label is useful for family navigation, but the public designation evidence is weaker than for the standard GBU-32 or the conflict-backed Mk-82 JDAM-ER.

  2. JDAM-ER concept trials demonstrate range extension

    Australian JDAM-ER concept trials in this period demonstrated the deployable wing kit's range-extension value before the later production program.

    Sources: DSTO smart bomb collaboration

  3. Boeing and the RAAF announce extended-range testing

    Boeing reported RAAF F/A-18 Classic Hornet tests at Woomera in which a 500-pound JDAM-ER wing kit extended range from about 15 miles to more than 45 miles.

  5. 1,000-pound Ukraine footage remains designation-limited

    The Aviationist reported Ukrainian Su-27 footage of 1,000-pound JDAM-ER bombs, but described the weapon's designation as unknown and only likely GBU-63.

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.

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.

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.

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. 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.
