U.S. Pacific Command joint forces, along with allied and partner forces, successfully carried out a live-fire sinking exercise as part of Valiant Shield 2026, targeting the thoroughly cleaned and decommissioned amphibious transport dock USS Juneau more than 200 nautical miles off the coast of Guam.
The Juneau launched in 1966 and saw action during the Vietnam War and Operation Desert Storm before it was decommissioned in 2008.
The evolution brought together air, surface and subsurface assets in coordinated strikes, allowing crews to sharpen critical skills in weapons employment and target engagement under realistic conditions that no simulator can fully replicate.
"This [exercise] provided an outstanding opportunity for our joint team to integrate capabilities across domains, honing the lethal precision and coordination essential for high-end maritime operations in the Pacific theater," said Navy Rear Adm. Eric Anduze, commander of Carrier Strike Group 5 and Task Force 70.
The coordinated strike included a long-range anti-ship missile deployed by an Air Force B-2 Spirit bomber. The LRASM is designed to detect and destroy enemy ships at long ranges. Developed by the U.S., it's a key component in the military's counter-maritime strike operations.
"The B-2's impressive performance underscores the U.S. military's commitment to adaptability and flexibility in the face of emerging security challenges," said Air Force Gen. Kevin B. Schneider, commander of Pacific Air Forces. "By prioritizing counter-maritime strike operations, we can maintain a decisive edge over adversaries, protect our national interests and ensure the free and open Pacific that underpin our global security."
With the deployment of the LRASM from the B-2 Spirit, the Pacific Air Forces has another tool in countering maritime threats. This milestone showcased high-end innovation reinforcing the War Department's commitment to safeguarding national interests and maintaining global security.
All operations adhered strictly to federal environmental regulations and international standards. Prior to the exercise, the target vessel underwent extensive preparation, including the complete removal of hazardous materials in line with Environmental Protection Agency guidelines. The selected site was surveyed to ensure the safety of marine life, vessels and personnel, with full compliance to the National Environmental Policy Act, Marine Mammal Protection Act and other key statutes.
Exercise Valiant Shield is a biennial, multilateral field training exercise conducted by the U.S. and partner nations in the Western Pacific focusing on joint, cross-combatant integration operating across sea, air, land and cyberspace.
