AN/AES-1 Airborne Laser Mine Detection System (ALMDS)

Last updated: 14 Apr 2025

Description
The AN/AES-1 Airborne Laser Mine Detection System (ALMDS) detects and localizes surface and near-surface moored sea mines using Light Detection and Ranging (LiDAR). The ALMDS is integrated with the MH-60S helicopter to provide rapid, wide-area reconnaissance and assessment of mine threats in littoral zones, confined straits, chokepoints, and amphibious objective areas. ALMDS can be deployed as part of a Mine Countermeasures Mission Package (MCM MP) onboard Littoral Combat Ships (LCS) or independently on other MH-60S as required to support fleet operations.
 
Background
The ALMDS complements other mine countermeasures systems that the U.S. Navy employs to rapidly detect, classify, and localize surface and near-surface moored sea mines for Carrier and Expeditionary Strike Group operation. This capability is critical in the littoral zones, confined straits, chokepoints, and the Amphibious Objective Area. ALMDS achieved Initial Operational Capability in November 2016. In 2022, ALMDS participated in the LCS MCM MP Initial Operational Test and Evaluation (IOT&E).
 
General Characteristics: Airborne Laser Mine Detection System
