Bell 525 Relentless vs Sikorsky S 76d vs Sikorsky S 92

The Bell 525 Relentless and Sikorsky S-76D are typically positioned as large and medium twin‑engine helicopters, respectively, while the Sikorsky S-92 sits in the heavy, long‑range offshore/utility category. In range, the S-92 is generally the strongest, optimized for longer offshore sectors and higher payloads, with typical published ranges commonly around the 500–600 nautical mile class depending on configuration. The Bell 525 is designed as a long‑range “super‑medium” with range often cited in a similar broad band, frequently around the mid‑500 nautical mile class, again varying with reserves and cabin fit. The S-76D, aimed at corporate and shorter offshore missions, generally offers a shorter range, commonly in the ~400 nautical mile class. For passenger capacity, the S-76D is usually configured around 8–12 passengers, the Bell 525 typically around 12–16, and the S-92 commonly around 19 passengers in offshore seating (with other layouts possible). Actual figures vary by interior, fuel, and mission equipment.
