    As of 2013, Sikorsky is refurbishing older S-61 aircraft for the US State Department. The new S-61T Triton program includes the upgrade and installation of composite main rotor blades, state-of-the-art glass cockpit, modular wiring harness, and modern survivability and force protection. According to the company, these enhancements result in an aircraft with improved safety, 15 percent greater performance, and a lower operating cost. Sikorsky is performing structural upgrades in its Troy, AL facility before sending the airframes to Carson Helicopter in Perhaskie, PA for fitting of dynamic components and interiors. The US Department of State has stated a need for up to 110 aircraft.
    As of March 2018, State Department has only confirmed 14 airframes with 13 deliveries completed. All were auctioning off by the General Services Administration (GSA)
