The Sikorsky S-70B/C Seahawk is the export variant of the
SH-60/MH-60 Seahawk multi-mission naval helicopter based on the
United States Army UH-60 Black Hawk. The most significant
modifications are the folding main rotor blades and a hinged tail to
reduce its footprint aboard ships. In January 2005, it was announced that 6 Sikorsky S-70B helicopters will be purchased, complete with anti-surface and anti-submarine weapons and sensors. 2 more Seahawks were ordered in 2013. The Seahawks are operated by RSAF pilots, with System Specialists of the Republic of Singapore Navy operating the sensors and weaponry. They operate from the Navy's new Formidable class frigates, and when operating from land are based at Sembawang Air Base.
