Sikorsky has unveiled upgraded versions of its S-92 helicopter that have been developed for a number of roles, including search and rescue (SAR).

The announcement was made at the HAI HELI-EXPO event in Atlanta, Georgia, on 5 March. Current S-92 helicopters retrofitted with the enhancements will be designated S-92A+, while those that have them included on the production line will be designated S-92B.
“The two variants will share a nearly identical configuration, with S-92B helicopters also featuring enlarged cabin windows and plans for a common cabin door suitable for offshore and SAR configurations,” Sikorsky said in a statement. “These changes to the venerable S-92 helicopter will introduce new technology that is focused on reliability and operating cost reduction, while at the same time delivering increased capability.”
As noted by the company, changes will increase commonality between the offshore, SAR, and utility configurations, and allow for speedier reconfiguration between roles. The new configuration will include the Phase IV main gearbox, and the General Electric CT7-8A6 engine (capable of producing more power in higher altitudes and hotter temperatures) will also be an option.
Current plans have initial availability set for 2022, although Sikorsky noted that this timeline will largely be driven by customer interest. In terms of costs, the company aims for the new-build S-92B to be cheaper than the current helicopter.
Since 2004 Sikorsky has delivered more than 300 production S-92 helicopters to civil and military customers, with nearly 1.5 million hours flown.
