Newly released pictures reveal the extensive modifications made to the MH-60M Black Hawks used by the U.S. Army’s elite 160th Special Operations Aviation Regiment, also known as the Night Stalkers. These helicopters, captured in images during an operation in the Bering Sea, are packed with advanced sensors, defensive systems, and communication gear to handle complex missions in challenging conditions.
  

Key Points: 

1. The MH-60M Black Hawks were photographed operating off the U.S. Navy’s San Antonio class amphibious warship USS John P. Murtha in the Bering Sea between Alaska and Russia.
2. The helicopters are equipped with specialized systems like the AN/APQ-187 Silent Knight terrain-following radar and the AN/ZSQ-2 sensor turret, designed for low-altitude, nap-of-the-earth flight profiles, even in poor weather.
3. The MH-60Ms also feature the Degraded Visual Environment Pilotage System (DVEPS), allowing for navigation in challenging visual conditions like dust, fog, and snow.
4. The helicopters have integrated self-defense systems, including visual/infrared missile, radar, and laser warning sensors, as well as active jammers to fend off threats.
5. These advanced Black Hawks are part of a larger special operations demonstration, dubbed Polar Dagger, aimed at showcasing the capabilities of special forces in the Arctic and Subarctic regions.
