F-35 Achieves Milestone with Dual External Release of GBU-54 LJDAM Precision Bombs

The United Operational Test Team has successfully conducted the first dual external release of GBU-54 Laser Joint Direct Attack Munitions (LJDAMs) from a Lockheed Martin F-35 aircraft at Edwards Air Force Base, California. This achievement marks a significant advancement in the F-35's air-to-surface strike capabilities.

GBU-54 LJDAM: Precision and Versatility

The GBU-54 LJDAM is a 500-pound precision-guided bomb that integrates a laser guidance kit with the GPS/INS-based navigation of the existing GBU-38 JDAM. This dual-mode guidance system allows the munition to accurately engage both stationary and moving targets, providing flexibility in various combat scenarios. The LJDAM has been extensively combat-proven by the U.S. Air Force, Navy, and Marine Corps since its introduction in 2008.

Test Execution and Objectives

The test was carried out using an F-35C from the U.S. Navy’s Air Test and Evaluation Squadron 9 Detachment. Pilot Cmdr. Michael “Squintz” Procelli emphasized that the ability to carry LJDAMs externally enhances the Joint Strike Fighter’s versatility, allowing it to respond effectively to asymmetrical threats in modern combat scenarios.

A key objective of the test was to evaluate the aircraft’s Stores Management System, which controls the deployment of onboard munitions. By releasing multiple bombs in rapid succession, the test provided crucial data on how the system manages and guides precision weapons under real-world conditions.

Advanced Targeting Capabilities

During the test, two GBU-54 bombs were deployed against a remote-controlled High-Speed Moving Target (HSMT). The F-35’s Electro-Optical Targeting System (EOTS), an advanced sensor suite integrating forward-looking infrared, infrared search and track, and a combat laser, successfully guided the bombs to their target. This cutting-edge system provides superior situational awareness compared to legacy targeting pods.

Operational Implications

The test was designed to reflect real-world battlefield scenarios, incorporating input from a Joint Tactical Air Controller (JTAC) to simulate combat operations. This ensures the F-35’s weapons integration meets operational demands in dynamic and unpredictable environments.

By demonstrating the safe separation and precise targeting of the LJDAM, this test underscores the F-35’s advanced strike capabilities. The success of this milestone further cements the F-35’s role as a next-generation multi-role fighter, capable of delivering GPS and laser-guided munitions with high accuracy in complex combat scenarios.

Conclusion

The successful dual external release of GBU-54 LJDAMs from the F-35 represents a significant advancement in the aircraft's operational capabilities. This achievement enhances the F-35's versatility and effectiveness in modern combat, solidifying its position as a cornerstone of next-generation air warfare.
