B-2 Spirit: New LRASM Capability Unleashed in Pacific Exercise
The B-2 Spirit stealth bomber just got a whole lot more dangerous — and the world’s naval commanders took notice. On June 27, during Exercise Valiant Shield 26, a B-2 Spirit launched an AGM-158C Long Range Anti-Ship Missile (LRASM) and sent the decommissioned USS Juneau to the bottom of the Pacific Ocean. It was a live-fire demonstration unlike anything publicly confirmed before, and it changes the strategic calculus in the Indo-Pacific overnight.
What makes the B-2 Spirit’s new LRASM capability unleashed in this Pacific exercise so significant isn’t just the technical feat — it’s what the combination signals. The world’s most advanced stealth bomber can now hunt and kill warships from standoff distances that make it nearly impossible to counter. A platform built to penetrate the most defended airspace on earth just acquired the ability to dominate the sea lanes as well.
This wasn’t a routine test. It was a deliberate, public reveal timed to a moment of rising maritime tension. U.S. Pacific Air Forces (PACAF) confirmed the event, describing it as the first publicly acknowledged demonstration of the B-2’s anti-ship strike capability. Here’s everything you need to know about what happened, why it matters, and what it means for the future of naval warfare in the Pacific.
The Historic Event: How the USS Juneau Met Its End
The sinking exercise — known in military parlance as a SINKEX — took place on June 27, north of the Mariana Islands. The target was the decommissioned USS Juneau (LPD-10), an amphibious transport dock that had long since retired from active service but still offered a structurally meaningful target for weapons testing.
A B-2 Spirit flying out of the region released a single AGM-158C LRASM. The missile completed its autonomous terminal guidance sequence, struck the vessel, and the USS Juneau sank. U.S. Airmen and Sailors from Pacific Air Forces conducted the exercise jointly, reflecting the kind of cross-domain coordination that modern warfare demands.
The exercise fell under the broader umbrella of Valiant Shield 26, a biennial joint exercise designed to integrate U.S. forces across air, land, and sea domains throughout the Indo-Pacific. While Valiant Shield regularly features live-fire events, this particular demonstration stood apart. Fox News described it as revealing the B-2’s “hidden ship killer capability” — language that tells you everything about how significant the moment was. This wasn’t just a weapons test. It was a strategic message.
Unleashing the LRASM: What Makes the AGM-158C a Game-Changer
To understand why this event matters, you need to understand what the LRASM actually is — and it’s considerably more sophisticated than a conventional anti-ship missile.
The AGM-158C Long Range Anti-Ship Missile is an advanced, precision-guided munition developed by Lockheed Martin, building on the airframe architecture of the AGM-158 JASSM family. But the LRASM isn’t just a JASSM with a maritime seeker bolted on. It represents a generational leap in anti-ship warfare for several reasons:
– Low Observable Design: The LRASM incorporates stealth shaping and materials to reduce its radar cross-section, making it significantly harder to detect and intercept than legacy anti-ship missiles like the Harpoon.
– Autonomous Targeting: The missile uses a multi-mode seeker, GPS/INS navigation, and onboard intelligence to identify, select, and engage specific targets within a group of ships — without requiring mid-flight guidance updates from the launch platform.
– Standoff Range: While the exact range remains classified, the LRASM is widely assessed to exceed 200 nautical miles, keeping the launch aircraft well outside the engagement envelopes of shipborne air defense systems.
– Penetration Capability: Its combination of low altitude terminal flight profiles, evasive maneuvering, and stealth design is purpose-built to defeat modern integrated air defense systems aboard peer-competitor warships.
Against a modern naval threat equipped with long-range surface-to-air missiles, legacy anti-ship weapons are increasingly vulnerable. The LRASM was designed specifically to address that problem.
The B-2 Spirit’s Evolving Role: From Strategic Bomber to Maritime Hunter
The B-2 Spirit was conceived during the Cold War as the ultimate penetrating strategic bomber — a platform capable of flying undetected into the most heavily defended airspace in the Soviet Union and delivering nuclear or conventional payloads. Its Northrop Grumman flying wing design, advanced low-observable coating, and terrain-following avionics made it the gold standard for strategic air power.
For decades, the B-2’s mission set centered on land attack. It struck targets in Yugoslavia, Afghanistan, Iraq, and Libya. It carries the Massive Ordnance Penetrator (MOP), the largest conventional bomb in the U.S. arsenal, designed to destroy hardened underground facilities. It can also deliver B61 and B83 nuclear gravity bombs.
But the addition of LRASM integration fundamentally expands that mission profile.
Why the Combination of B-2 and LRASM Is Uniquely Powerful
Here’s the strategic math that adversary planners now have to solve: the B-2 can fly from Whiteman Air Force Base in Missouri or forward bases like Diego Garcia and Anderson Air Force Base in Guam, penetrate defended airspace undetected, and release LRASMs hundreds of miles from the target. The missiles then fly their autonomous terminal attack profiles while the B-2 exits the area.
No other platform delivers this combination of stealth penetration, global range, and maritime precision strike capability. An adversary naval task force would face a threat it cannot reliably detect, cannot reliably intercept at the launch point, and cannot reliably defend against at the terminal phase. That’s a three-layered defensive problem that no current naval air defense architecture solves cleanly.
The B-2 can carry up to 40,000 pounds of ordnance across its two internal weapon bays. While the exact number of LRASMs it can carry in a combat load remains unconfirmed publicly, even a small salvo from a single aircraft represents a lethal threat to a surface action group.
Strategic Implications in the Indo-Pacific
The timing and location of this demonstration were not accidental. The Indo-Pacific is the defining theater of Great Power Competition, and the maritime dimension of that competition is intensifying.
China’s People’s Liberation Army Navy (PLAN) has grown into the world’s largest navy by hull count, and its surface combatants are equipped with increasingly sophisticated anti-ship and anti-air missile systems. The DF-21D and DF-26 “carrier killer” ballistic missiles have long complicated U.S. carrier strike group operations in the Western Pacific. China’s A2/AD — anti-access/area denial — bubble, centered on the South China Sea and extending into the Western Pacific, is designed to prevent U.S. forces from operating freely in the region during a conflict.
The B-2/LRASM combination directly addresses this challenge in ways that other platforms struggle to match.
Countering A2/AD and Supporting Distributed Maritime Operations
The U.S. Navy’s evolving Distributed Maritime Operations (DMO) concept envisions dispersing naval forces across a wide area rather than concentrating them in traditional carrier strike group formations. The goal is to complicate adversary targeting while maintaining lethal firepower across the battlespace. Long-range stealth platforms capable of maritime strike are essential enablers of that concept.
A B-2 launching LRASMs from outside the A2/AD envelope — or even from within it, given the platform’s low observable characteristics — provides exactly the kind of reach and lethality that DMO requires. It creates targeting problems for adversary fleets that cannot be solved by tracking the launch platform, because the B-2 is simply too difficult to detect in time to react.
This is also a powerful deterrence tool. Any adversary naval commander planning a contested approach in the Western Pacific now has to account for the possibility that an undetected B-2 is somewhere in the battlespace, armed with missiles that their ship-based radar systems may not see until it’s too late.
Exercise Valiant Shield: Where New Capabilities Become Validated Doctrine
Valiant Shield is more than a routine training event. It’s a biennial capstone exercise that allows Pacific Air Forces, U.S. Navy, and other joint force components to integrate their capabilities under realistic conditions, stress-test new tactics, and validate new weapon systems against real targets.
A SINKEX specifically serves a critical validation function. Shooting at simulated targets in a controlled test range tells you a great deal about a weapon’s technical performance. Shooting at an actual decommissioned vessel in open ocean — with real sea states, realistic target geometry, and no artificial adjustments — tells you how that weapon actually performs in the conditions it will face in combat. The fact that PACAF chose to conduct the B-2/LRASM SINKEX as part of Valiant Shield 26 signals that this capability is no longer in early development. It’s ready, validated, and being integrated into operational doctrine.
The Future of Air Power and Naval Warfare
The B-2’s new maritime strike role raises important questions about where U.S. military doctrine goes from here. If you follow military aviation developments — and the kind of community that reads deeply into defense topics will find this as fascinating as any list of extraordinary military facts — this integration opens several doors worth watching.
The B-21 Raider, the B-2’s successor currently entering service, was designed from the outset with greater weapons flexibility. If LRASM integration proves as operationally valuable as the Valiant Shield demonstration suggests, similar or expanded maritime strike capabilities on the B-21 become a logical next step. The LRASM itself is also being continuously upgraded, with improved range, seekers, and networking capabilities in development.
More broadly, this development accelerates the blurring of traditional service roles. The Air Force now has a credible maritime strike capability that complements — and in some scenarios exceeds — what surface ships and submarines can bring to an anti-ship fight. Joint force integration across the air and maritime domains is no longer just a planning concept. The USS Juneau’s wreckage proves it works.
Conclusion: A Pivotal Moment for U.S. Power Projection
The B-2 Spirit’s new LRASM capability unleashed in this Pacific exercise represents one of the most significant expansions of U.S. airborne strike power in years. By combining the B-2’s unmatched penetration range and stealth with the LRASM’s autonomous, low-observable anti-ship precision, the U.S. military has created a maritime strike threat that adversary naval planners have no reliable answer to.
The sinking of the USS Juneau wasn’t just a training event — it was a demonstration, a message, and a validation. It tells potential adversaries in the Indo-Pacific that the United States can threaten their naval forces from ranges and at detection levels that traditional fleet defense architectures cannot address. And it tells U.S. allies and partners that American airpower remains adaptable, innovative, and ready to meet evolving threats wherever they emerge.
In a theater defined by vast ocean distances and increasingly capable peer competitors, that matters enormously.

Frequently Asked Questions
What is the AGM-158C LRASM and how does it differ from older anti-ship missiles?
The AGM-158C LRASM (Long Range Anti-Ship Missile) is a next-generation precision anti-ship cruise missile built by Lockheed Martin. Unlike older missiles like the Harpoon, the LRASM features stealth design characteristics, autonomous targeting that allows it to identify and engage specific ships within a group, a standoff range exceeding 200 nautical miles, and low-altitude terminal attack profiles designed to defeat modern ship-based air defenses.
When did the B-2 Spirit fire the LRASM and what was the target?
The live-fire sinking exercise (SINKEX) took place on June 27, north of the Mariana Islands, during Exercise Valiant Shield 26. The target was the decommissioned USS Juneau (LPD-10), an amphibious transport dock. The B-2 successfully launched a single AGM-158C LRASM, which sank the vessel.
Is this the first time the B-2 has used an anti-ship missile?
This was the first public revelation of the B-2’s ability to employ the LRASM. Prior to this demonstration, the B-2’s anti-ship strike capability had not been officially confirmed or publicly acknowledged by the U.S. Air Force or PACAF.
Why does the B-2 Spirit’s LRASM capability matter strategically in the Indo-Pacific?
The B-2/LRASM combination directly counters China’s anti-access/area denial (A2/AD) strategy in the Western Pacific. Because the B-2 is virtually undetectable and can operate at extreme range, it can launch LRASMs against enemy surface fleets from positions that are extremely difficult to detect or counter. This creates serious targeting problems for adversary naval planners and strengthens U.S. deterrence in the region.
What is Exercise Valiant Shield?
Valiant Shield is a biennial, joint U.S. military exercise conducted in the Indo-Pacific region. It focuses on integrating air, land, and sea forces under realistic conditions to validate tactics, test new weapon systems, and improve joint force coordination. The 2026 edition, Valiant Shield 26, featured the landmark B-2/LRASM sinking exercise as a major demonstration of advanced strike capability.
How many LRASMs can the B-2 Spirit carry?
The exact combat load configuration of LRASM on the B-2 has not been officially confirmed. The B-2 has two internal weapon bays capable of carrying up to 40,000 pounds of ordnance total, which suggests the capacity to carry a meaningful salvo of LRASMs — enough to pose a lethal threat to an adversary surface action group.
