B-2 Stealth Bomber Conducts First Public Launch of Long-Range Anti-Ship Missile in Pacific Exercise

The calculus of naval warfare in the Pacific has fundamentally shifted. For decades, the United States relied on its carrier strike groups and attack submarines to project maritime power and deter aggression across the vast expanses of the Indo-Pacific. Surface fleets, however, are increasingly vulnerable to sophisticated anti-access and area-denial networks designed to keep them thousands of miles from contested shores. Now, the ability to sink heavily defended warships has been decoupled from the sea entirely. By integrating advanced anti-ship missiles onto stealth bombers, military planners have created a strike complex that can originate from the American heartland, bypass traditional radar horizons, and dismantle a naval flotilla before surface combatants ever make contact.

The theoretical became operational on June 27, 2026. Flying over the Philippine Sea, a B-2 Spirit stealth bomber opened its weapons bay and released an AGM-158C Long Range Anti-Ship Missile. The target was the ex-USS Juneau, a decommissioned Austin-class amphibious transport dock positioned more than 200 nautical miles off the coast of Guam. The live-fire strike was part of a coordinated sinking exercise, known as a SINKEX, designed to test the weapon's efficacy against a realistic maritime target under combat conditions.[6][7]

Two days after the missile found its mark, U.S. Pacific Air Forces formally disclosed the event. The announcement marked the first public acknowledgment that the Air Force’s premier stealth bomber had been integrated with the military's most advanced ship-killing missile. While the B-2 has served as America’s primary nuclear deterrent and conventional deep-strike platform for three decades, its role has historically been confined to attacking heavily defended land targets. The successful SINKEX officially expands the aircraft's portfolio into the maritime domain.[3][7]

The architecture of this new capability relies on the AGM-158C LRASM, a weapon derived from the Joint Air-to-Surface Standoff Missile. Unlike older anti-ship weapons that require constant mid-course updates or active radar homing that alerts targets to their approach, the LRASM is designed to operate with a high degree of autonomy. Once released, the missile uses passive sensors and advanced routing algorithms to navigate around known air defense networks, identifying and classifying specific target ships within a crowded maritime environment without emitting a telltale radar signature.[2][6]

The physical specifications of the missile dictate the tactical geometry of the engagement. The LRASM carries a 1,000-pound penetrator and blast-fragmentation warhead, sufficient to cripple or sink major surface combatants. More importantly, it boasts a publicly stated range of more than 200 nautical miles—approximately 370 kilometers. This stand-off distance is the critical variable, allowing the launch aircraft to release its payload while remaining safely outside the engagement rings of modern shipborne surface-to-air missile systems.[1][2]

While the Air Force has not disclosed exactly how many LRASMs a single B-2 can carry, defense analysts point to the bomber's existing payload capacity for the identically sized JASSM family. Based on those dimensions, a B-2 could theoretically load up to 16 of the stealthy anti-ship missiles internally. This capacity transforms a single bomber into what naval strategists term a "fleet killer," capable of launching a saturated, multi-axis attack against a naval formation in a single pass while preserving the aircraft's low-observable radar cross-section.[2][5]

The strategic implications of this pairing are profound. A stealth bomber carrying a stealthy, autonomously guided anti-ship missile is a combination engineered for a very specific scenario: hunting warships inside a modern anti-access bubble. Instead of relying on non-stealthy platforms like the B-1B Lancer or carrier-based F/A-18 Super Hornets—which must either fire from extreme distances or risk detection—the B-2 can penetrate contested airspace to launch its weapons from optimal vectors, drastically reducing the adversary's reaction time.[2][4]

The June 27 strike did not occur in a vacuum. It was a centerpiece of Valiant Shield 26, a massive biennial U.S. military exercise held around the Mariana Islands. The drill focuses heavily on joint operations, integrating air, sea, land, and cyber domains to simulate high-end conflict scenarios in the Pacific. By conducting the SINKEX during Valiant Shield, the Pentagon deliberately showcased the capability in the exact geographic theater where it would theoretically be employed.[5][7]

The exercise also demonstrated the architecture of a modern, networked kill chain. The B-2 did not operate as a lone wolf; the sinking of the ex-Juneau was a coordinated effort involving multiple domains. After the bomber's LRASM struck the vessel, allied assets continued the assault. According to naval reports, the final, decisive blow that sent the amphibious transport dock to the bottom of the Philippine Sea was a heavy torpedo delivered by a Japan Maritime Self-Defense Force submarine, highlighting the integration of U.S. aerospace power with allied undersea capabilities.[5]

This is not the B-2 fleet's first foray into maritime strike, though it is by far the most potent. In 2024, a B-2 participated in the RIMPAC exercise by dropping a QUICKSINK guided bomb on the decommissioned USS Tarawa. The QUICKSINK program utilizes a modified, low-cost Joint Direct Attack Munition designed to break a ship's keel. However, as a gravity bomb, QUICKSINK requires the bomber to fly almost directly over the target. The LRASM integration solves this vulnerability, providing the critical stand-off range necessary to survive against a peer adversary.[4][6]

The introduction of this capability comes as the U.S. military grapples with a shifting balance of naval power. The Air Force currently operates a small fleet of just 19 B-2 Spirits, flying primarily out of Whiteman Air Force Base in Missouri. By turning these strategic assets into conventional maritime strike platforms, the Pentagon gains a highly flexible tool that can deploy globally within hours, threatening hostile fleets without the weeks-long transit times required to reposition a carrier strike group.[2]

For adversary naval planners, the B-2 and LRASM combination forces a radical recalculation of defensive geometry. A fleet can no longer simply monitor the surface horizon or track the approach of non-stealthy aircraft. Defending against an attack that originates from an undetected platform hundreds of miles away requires pushing sensor networks and combat air patrols far beyond the immediate battlespace, straining resources and complicating fleet logistics.[1][4]

Despite the public demonstration, significant uncertainties remain regarding the program's scope. The Air Force has not disclosed when the LRASM integration was actually completed, nor whether the June exercise marked the first time a B-2 had ever fired the weapon. Notably, the Pentagon's fiscal 2027 budget request omitted any reference to LRASM integration on the B-2, leaving the timeline and funding mechanisms for this capability opaque to the public.[2]

Ultimately, the Valiant Shield SINKEX serves as a stark physical receipt of American military intent. As Pacific Air Forces Commander Gen. Kevin B. Schneider noted following the exercise, prioritizing counter-maritime strike operations is viewed as essential to maintaining a decisive edge. By proving that its most elusive bomber can now sink ships from afar, the United States is signaling that the defense of the Pacific will increasingly rely on the integration of stealth and autonomy in the air.[3][7]
