Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b vs Gulfstream G700

The Airbus H225, Bell 525 Relentless, and Enstrom 480B are helicopters, while the Gulfstream G700 is a long‑range business jet in a different class. In category, the H225 is a heavy, twin‑engine rotorcraft often used for offshore, search and rescue, and utility roles; the Bell 525 is a modern super‑medium, twin‑engine helicopter aimed at offshore and corporate transport; and the Enstrom 480B is a light, single‑engine helicopter typically used for training, patrol, and short executive hops. The G700 is an ultra‑long‑range, high‑speed executive jet designed for intercontinental travel. On range, the G700 is the clear outlier, capable of roughly 7,500 nautical miles, enabling nonstop global city pairs. The H225 and Bell 525 offer medium helicopter ranges generally in the few‑hundred‑nautical‑mile class (often around 500–600 nm depending on configuration and reserves), while the 480B is shorter‑range, commonly around the low‑to‑mid‑300 nm class. Passenger capacity also separates them: the G700 typically seats a small group in luxury (often 10–19), the H225 can carry the most in high‑density layouts (up to around 19), the Bell 525 is usually configured for roughly 16, and the Enstrom 480B seats up to 5.
