GBU-35 BLU-110 Joint Direct Attack Munition

Also known as
  • GBU-35

The GBU-35 BLU-110 Joint Direct Attack Munition was a U.S. Navy 1,000-pound JDAM designation for a BLU-110 bomb body fitted with Boeing's GPS/INS tail kit. Sources separate it from the Mk 83-bodied GBU-32 while placing both in the same 1,000-pound JDAM class, and direct conflict sources document GBU-35 use in Afghanistan and Iraq.

Variants

The GBU-35 label belongs to the 1,000-pound JDAM designation split. It identifies the BLU-110 warhead path that Designation Systems says the Navy later folded into the broader GBU-32(V)2/B naming practice.

Bomb Body Compatibility

The GBU-35 designation sits in the same 1,000-pound JDAM weight class as the GBU-32 but is tied to the BLU-110/B bomb body.

Bomb body and naming split

The reader-visible distinction is the bomb body: Mk 83 for the classic GBU-32 path and BLU-110/B for the separate GBU-35 label used in older Navy designation material.

Carrier Aircraft

Public sources describe the Navy's 1,000-pound GBU-32 and GBU-35 JDAMs around the F/A-18 carrier strike ecosystem.

Designation Notes

The GBU-35 name is best read as a narrow Navy designation inside the 1,000-pound JDAM class, not as a separate guidance concept from JDAM.

Timeline

GBU-35 BLU-110 Joint Direct Attack Munition Key Events

  1. First production JDAM delivered

    Boeing delivered the first production JDAM to the Department of Defense at its St. Charles facility, establishing the production base for later JDAM-family weapons.

  2. GBU-35 Iraq use quantified

    Human Rights Watch's Off Target report listed 675 GBU-35 JDAMs in its table of guided air-delivered weapons used during the 2003 Iraq campaign.

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.

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.

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.

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 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.
