Airbus Helicopters H225 vs Bell 525 Relentless vs Enstrom 480b

The Airbus H225 is a heavy, long‑range twin‑engine helicopter aimed at offshore energy, SAR, and utility lift. It typically offers the greatest mission radius and endurance of the three and the highest passenger capacity, commonly configured around the high‑teens to roughly twenty passengers depending on layout and equipment. The Bell 525 Relentless is a super‑medium twin designed for high speed and long‑range offshore and corporate missions. Its range is generally competitive with, and often closer to heavy‑class capability than older super‑mediums, but it usually carries fewer passengers than an H225. Cabin layouts are commonly in the mid‑teens, varying by mission kit. The Enstrom 480B is a light single‑engine helicopter oriented toward utility, patrol, training, and personal/industrial support. Compared with the two twin‑engine offshore types, it has a much shorter range and far lower passenger capacity, typically seating a small group (around four passengers plus a pilot), and it targets lower operating complexity rather than maximum payload or offshore reach.
