The resurgent offshore energy industry is driving fresh demand for the S-92A, Sikorsky’s largest civil helicopter. Sikorsky delivered just four in 2022 and three last year. But three more are on the assembly line at the company’s West Palm Beach, Florida facility, and the company is in the final stages of negotiations for a block of 14 new-build helicopters for delivery in 2025 and 2026.

These helicopters will be delivered in the upgraded “A+” configuration that includes the new Phase IV main gearbox and a menu of choices including uprated GE CT7-8A6 engines that offer better high/hot performance. The upgraded gearbox uses a supplemental oil pump and additional oil lines to reuse main gearbox oil that is accumulated in a lower sump in the event of primary lubrication failure.
