Sikorsky S92 vs Airbus Helicopters H175 vs Leonardo Aw139

The Sikorsky S-92, Airbus H175, and Leonardo AW139 all sit in the medium twin-engine helicopter category, but they emphasize slightly different missions. The S-92 is generally regarded as a heavy-medium aircraft optimized for offshore transport and high-utilization operations, typically offering the largest cabin and the most robust “workhorse” feel of the three. The H175 is a modern medium twin positioned strongly for offshore and executive/VIP roles, balancing cabin comfort with efficient performance. The AW139 is a versatile medium twin widely used for EMS, law enforcement, offshore, and corporate flying, often valued for flexibility and operating economics. In range, the S-92 and H175 are commonly configured to deliver longer offshore-style legs, with the AW139 typically a bit shorter depending on fuel tanks and mission equipment, though all three can be equipped to extend endurance. For passenger capacity, the S-92 usually carries the most in typical offshore seating, often around 16–19 passengers. The H175 is commonly in a similar but slightly lower bracket, often about 16–18. The AW139 is typically lower, frequently around 12–15, with many layouts tailored to mission needs.
