MELBOURNE, FL, Oct 21, 2025 – Northrop Grumman has delivered the first Airborne Laser Mine Detection System (ALMDS) sensor pod to the Republic of Korea, marking a step in advancing the country’s maritime mine countermeasure capabilities. The system uses airborne lasers to detect and locate naval mines, strengthening South Korea’s coastal defense and improving maritime security.
- In 2023, Korea Aerospace Industries (KAI) awarded Northrop Grumman a contract to provide ALMDS technology and technical support for the design and manufacturing phase of the Korean Mine Countermeasures Helicopter (KMCH) program.
- ALMDS technology detects and classifies naval mines in coastal waters. It is used by the U.S. Navy and Japan Maritime self-defense force.
- ALMDS is capable of day or night operations, allowing it to scan large areas and locate naval mines. It provides target coordinates to support mine neutralization from helicopter platforms.
Janice Zilch, vice president, multi-domain command and control programs, Northrop Grumman: “ALMDS exemplifies Northrop Grumman’s ability to deliver trusted technology for critical missions, consistently performing where it matters most. Our collaboration with KAI shows our commitment to advancing defense capabilities together with Korean industry and delivering vital capabilities, ensuring the safety and security of our allies.”
Northrop Grumman’s AN/AES-1 ALMDS is manufactured in the United States. It detects, classifies, and locates floating and near-surface moored mines. Northrop Grumman has delivered 24 ALMDS units to the U.S. Navy and four to the Japan Maritime Self-Defense Force, supporting mine countermeasure operations worldwide.
