First flight 08 Aug 1989. Initial IOC 01 Oct 1989. From 2007 to 2014, US Coast Guard HH-60Js were upgraded to the MH-60T version. The MH-60T version includes a glass cockpit, enhanced optics and infrared sensors. An provided "airborne use of force package" includesa 7.62mm machine gun and a .50 caliber Barrett M82 semi-automatic rifle for firing warning and disabling shots, as well as hull armor to protect the aircrew from small arms fire (source: USCG Acquisition Directorate).
