United States Marine Corps F-35B Drops Eight StormBreaker Bombs in Single Flight
The United States Marine Corps successfully executed the first ripple release of eight Small Diameter Bomb II units from an F-35B aircraft on September 15 at the Yuma Proving Ground in Arizona, Business AM reported. This test demonstrates that the stealth fighter can deploy multiple precision-guided munitions along a single flight path rather than requiring separate sorties.
Developed by Raytheon in collaboration with the US Navy and Air Force, the 115-kilogram SDB II—also known as the StormBreaker—uses automated recognition software to strike moving targets in adverse weather conditions from a standoff distance of at least 74 kilometers. The weapon’s ripple release capability allows pilots to define a specific kill box where weapons automatically redistribute targets among themselves if an individual munition fails or gets intercepted, significantly reducing pilot workload and exposure to enemy air defenses.
Software Integration Delays and Pentagon Procurement Goals
Integrating the StormBreaker into the F-35 fleet presents unique engineering hurdles because the stealth jet must carry its weapons internally. This spatial constraint poses a particular challenge for the F-35B variant due to its vertical-landing machinery. While the weapon is already cleared for use on the F-15E and F/A-18E/F, software development delays threaten to push back full operational integration on the F-35 by up to four years, according to a Government Accountability Office report.
Lockheed Martin is working to resolve these integration bottlenecks through the Block 4 modernization program, which builds on TR-3 technology upgrades to improve sensor and weapon capabilities. Despite these software hurdles, the Pentagon has increased its procurement target from roughly 21,000 to more than 31,000 StormBreaker units. Raytheon is currently scaling up production to fulfill this expanded order while concurrently pursuing aerodynamic and motor enhancements to extend the weapon’s overall range.
