🔥 Trending US Airmen and Sailors Conduct SINKEX Exercise with B-2 Bomber

The USS Juneau Valiant Shield SINKEX refers to a live-fire sinking exercise (SINKEX) conducted during the Valiant Shield 2026 military exercise, in which the decommissioned U.S. Navy Austin-class amphibious transport dock ship USS Juneau (LPD-10) was intentionally sunk ²³⁷. This event took place on June 27, 2026, in the Philippine Sea, specifically within the Mariana Island Range Complex, more than 200 nautical miles off the coast ⁶⁷¹⁰.

Purpose of a SINKEX

SINKEXs are crucial training events for naval forces, allowing them to test their weapons systems and tactics against a realistic target – a full-sized ship ⁴. These exercises provide invaluable data on weapon effectiveness, targeting procedures, and the cumulative effects of multiple strikes ⁴.

Key Participants and Weapons Used

The sinking of the USS Juneau was a multilateral effort involving U.S. Pacific Command joint forces, along with allied and partner forces ³⁷. Several advanced weapon systems were employed during the exercise:

• Japanese Torpedo: A Japan Maritime Self-Defense Force submarine fired a torpedo at the USS Juneau, playing a significant role in its sinking ¹²⁶.
• B-2 Spirit Stealth Bomber with LRASM: For the first time, a U.S. Air Force B-2 Spirit stealth bomber launched an AGM-158C Long Range Anti-Ship Missile (LRASM) against a surface target during this SINKEX ⁵¹⁰. This demonstrated a new maritime strike capability for the B-2 ⁵.

Significance of the USS Juneau SINKEX

The SINKEX of the USS Juneau during Valiant Shield 2026 was more than just a training drill; it carried strategic and symbolic importance:

• Demonstration of Joint and Allied Capabilities: The exercise showcased the interoperability and combined strike capabilities of the U.S. and its allies, particularly Japan, in a complex maritime environment ³⁶.
• Testing Advanced Weapon Systems: The successful deployment of the LRASM from a B-2 bomber against a moving target highlighted advancements in long-range anti-ship warfare and the multi-domain capabilities of the U.S. military ⁵¹⁰.
• Realistic Training Scenario: Sinking a large, decommissioned vessel provides a level of realism that cannot be replicated in simulations, offering critical insights into naval combat effectiveness ⁴.
• Environmental Considerations: Before being sunk, decommissioned ships like the USS Juneau undergo extensive cleaning to remove hazardous materials, ensuring the SINKEX complies with environmental regulations ⁹.

The event underscores the ongoing efforts by the U.S. and its partners to enhance their maritime defense and strike capabilities in the Pacific region ⁴.
