Airbus Helicopters H155 vs Airbus Helicopters H160 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 92

By category, the Airbus H155 is a medium twin often positioned for corporate/VIP and EMS, while the H160 is a newer-generation medium twin aimed at premium offshore, corporate, and public services. The Airbus H175, Leonardo AW189, and Sikorsky S-92 sit in the super‑medium class primarily optimized for offshore transport and SAR, with higher payload and cabin volume than medium twins. The Bell 525 Relentless is also super‑medium, designed to bridge medium and heavy missions with high cruise and modern avionics. The Leonardo AW139 is a high‑end medium twin widely used across offshore, EMS, law enforcement, and utility roles. On range, the H160 and AW139 generally offer medium‑class ranges around the mid‑hundreds of nautical miles depending on configuration, the H155 tends to be similar but often slightly more limited, while the super‑mediums (H175, AW189, S‑92, and 525) typically extend range further, commonly into the upper‑hundreds of nautical miles with appropriate fuel fit. On passenger capacity, H155 and H160 usually seat around 12, the AW139 often up to 15, and the super‑mediums typically carry roughly 16–19 passengers, with the S‑92 and AW189 commonly at the higher end in offshore layouts.
