Airbus Helicopters H175 vs Leonardo Aw139 vs Sikorsky S92

The Airbus Helicopters H175 and the Leonardo AW139 are both twin‑engine, medium‑class helicopters commonly used for offshore transport, SAR, and VIP or utility missions, but they sit in slightly different parts of the market. The H175 is generally positioned a step larger in “super‑medium” class, optimized for offshore payload and cabin volume, while the AW139 is a widely adopted medium twin known for versatility and strong performance across many roles. In typical configurations, the H175 usually offers higher passenger seating, often around 16 offshore passengers, whereas the AW139 is more commonly arranged for about 12–15 passengers depending on layout and mission equipment. In range, both can be equipped for long legs, but the H175 is generally marketed with a longer standard mission radius and endurance for offshore operations, while the AW139’s range is competitive and varies significantly with fuel options, payload, and reserves. Overall, the H175 tends to favor slightly more cabin and payload for offshore-style missions, while the AW139 emphasizes broad mission flexibility and fleet commonality.
