Airbus Helicopters H175 vs Leonardo Aw139 vs Sikorsky S 92

The Airbus Helicopters H175, Leonardo AW139, and Sikorsky S-92 all sit in the medium twin-engine class, but they target slightly different missions. The AW139 is typically viewed as the lighter, more versatile medium twin commonly used for EMS, law enforcement, and short-to-medium offshore runs. The H175 is a larger “super-medium” aimed strongly at offshore transport and corporate/VIP use, offering a step up in cabin volume and comfort versus the AW139 while remaining smaller than the S-92. The S-92 is a heavy-class helicopter and is most often selected for high-demand offshore and SAR roles where payload, redundancy, and rough-weather capability are priorities. In range, the AW139 generally offers the shortest reach of the three, the H175 is usually next with longer offshore-oriented legs, and the S-92 often matches or exceeds the H175 depending on configuration and reserves. For passenger capacity, typical layouts are around 12–15 passengers for AW139, about 16–18 for H175, and roughly 19 for S-92, with exact numbers varying by seating density, fuel, mission equipment, and regulatory limits.
