USNS Invincible

[1] Like other members of the Stalwart class of ocean surveillance ships, the original mission of the Invincible was to patrol the oceans looking for submarines with her Surveillance Towed Array Sensor System (SURTASS), a large passive sonar array.Invincible provides a platform for the Cobra Gemini dual-band radar developed by the United States Air Force to support data collection requirements on theater ballistic missiles.[2] The Military Sealift Command retains custody for United States Air Force use for deploying a mobile surveillance and tracking radar system.[2] Invincible deployed to the Persian Gulf in 2012, passing through the Strait of Hormuz on 19 May 2012 in convoy with British minesweepers.[citation needed] The ship was inactivated on 15 December 2021 and the US Navy plans to repurpose it into a training vessel or store it as part of the National Defense Reserve Fleet.
