Bell 525 Relentless vs Gulfstream G700 vs Sikorsky S 92

The Bell 525 Relentless is a modern super‑medium helicopter aimed at offshore transport and corporate shuttle missions. It typically carries around 16 passengers in a high‑density layout (fewer in executive configurations) and offers roughly 500–600 nautical miles of range depending on payload and reserves. The Sikorsky S‑92 is a larger, heavy helicopter widely used for offshore oil and gas and SAR support; it commonly seats about 19 passengers in standard transport layouts and has a similar but often slightly longer practical range, roughly 500–650 nautical miles, again varying with mission equipment and load. The Gulfstream G700 is a long‑range business jet in an entirely different category, optimized for intercontinental travel at high speed and altitude. It typically accommodates about 13–19 passengers in executive cabin arrangements and can fly approximately 7,500 nautical miles, enabling nonstop city pairs that are far beyond helicopter capability. In short, the 525 and S‑92 prioritize vertical lift and short-to-medium range utility, while the G700 prioritizes long-range, high-speed point-to-point travel.
