Upgrades
Experience during Operation Enduring Freedom and Operation Iraqi Freedom led US air power planners to seek additional capabilities in one package, resulting in ongoing program upgrades to place a precision terminal guidance seeker in the JDAM kit. The Laser JDAM (LJDAM), as this upgrade is known, adds a laser seeker to the nose of a JDAM equipped bomb, giving the ability to engage moving targets to the JDAM. The Laser Seeker is a cooperative development between Boeing Integrated Defense Systems and Israel's Elbit Systems. It is called Precision Laser Guidance Set (PLGS) by Boeing and consists of the Laser Seeker itself, now known as DSU-38/B, and a wire harness fixed under the bomb body to connect the DSU-38/B with the tailkit. During FY2004, Boeing and the U.S. Air Force began testing of the laser guidance capability for JDAM, with these tests demonstrating that the system is capable of targeting and destroying moving targets. This dual guidance system retains the ability to operate on GPS/INS alone, if laser guidance is unavailable, with the same accuracy of the earlier JDAM.
On 11 June 2007, Boeing announced that it had been awarded a $28 million contract by the U.S. Air Force to deliver 600 laser seekers (400 to the Air Force and 200 to the Navy) by June 2009. According to the Boeing Corporation, in tests at Nellis Air Force Base, Nevada, Air Force F-16 Fighting Falcons and F-15E Strike Eagles dropped twelve (12) 500 pounds (230 kg) LJDAMs that successfully struck high-speed moving targets. Using onboard targeting equipment, the launch aircraft self-designated, and self-guided their bombs to impact on the targets. In addition to the LJDAM kits, Boeing is also testing under a Navy development contract, an anti-jamming system for the JDAM, with development expected to be completed during 2007, with deliveries to commence in 2008. The system is known as the Integrated GPS Anti-Jam System (IGAS). Boeing announced on 15 September 2008, that it had conducted demonstration flights with the LJDAM loaded aboard a B-52H.
The GBU-54 LJDAM made its combat debut on August 12, 2008 in Iraq when a F-16 from the 77th Fighter Squadron engaged a moving vehicle in Diyala province. Furthermore, the GBU-54 LJDAM made its combat debut in the Afghan theater by the 510th Fighter Squadron in October 2010.
In September 2012, Boeing began full-rate production of Laser JDAM for US Navy and received a contract for more than 2,300 bomb kits.
On 24 July 2008 Germany signed a contract with Boeing to become the first international customer of LJDAM. Deliveries for the German Air Force began in mid-2009. The order also includes the option for further kits in 2009.
