Airbus Helicopters H225 vs Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Sikorsky S 92

Airbus’s H225 and Sikorsky’s S‑92 sit in the heavy, long-range offshore/utility class. Both typically carry around 18–19 passengers in standard transport layouts and are chosen for North Sea–style missions; in range terms they are broadly similar, generally in the mid‑400 to mid‑500 nautical mile class depending on configuration and reserves, with the H225 often cited with slightly higher brochure range and the S‑92 strongly competitive in real offshore payload/radius profiles. Bell’s 525 Relentless is a modern “super-medium” rather than a true heavy. It is aimed at offshore and corporate/VIP work with a typical seating fit in the mid‑teens to about 16 passengers, and it targets long legs comparable to the heavy twins on paper, commonly quoted in roughly the ~500 nautical mile neighborhood depending on fit and mission assumptions. The MD Helicopters (McDonnell Douglas) 902 Explorer is a much smaller light twin, typically configured for about 8 passengers. Its practical range is substantially shorter than the offshore-oriented machines, commonly closer to the ~300–400 nautical mile class depending on fuel and payload.
