Bell 525 Relentless vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-92 sit in different helicopter classes, which drives most of the practical differences. The Bell 525 is a modern “super‑medium” twin aimed at corporate, offshore, and public-service missions that want strong performance with a smaller footprint than a heavy helicopter. The Sikorsky S-92 is a larger “heavy” twin widely used for offshore oil and gas transport, SAR, and government/VIP roles where payload and cabin volume are priorities. On range, both are designed for offshore legs, but the S-92 generally offers longer endurance and greater mission flexibility when configured for maximum fuel, reflecting its heavier-class role. The 525 targets competitive offshore range for its class, but typically doesn’t match the S-92’s longest-range configurations. For passenger capacity, the S-92 normally carries more people in typical offshore layouts, often around the high teens, while the Bell 525 is commonly configured for fewer, roughly in the low-to-mid teens depending on interior and mission equipment.
