Airbus Helicopters H155 vs Airbus Helicopters H160 vs Leonardo Aw139 vs Leonardo Aw169 vs Sikorsky S 76d

All five are medium twin-engine helicopters used for offshore, EMS, corporate, and utility work, but they span two size classes. The Airbus H155 and Sikorsky S‑76D sit in the “medium” segment: both typically carry about 12 passengers in a standard transport layout, with ranges commonly in the roughly 450–500+ nautical mile class depending on fuel, reserves, and fit. The Leonardo AW139 is generally the largest of this group, often configured for about 12–15 passengers and offering similar or slightly better practical range than H155/S‑76D in many mission profiles, with strong payload margins. The Airbus H160 is a newer-generation medium twin; it is usually set up around 12 passengers and targets comparable or better range than the H155, often quoted around the mid‑500 nautical mile class in typical configurations. The Leonardo AW169 is a lighter “intermediate” twin: it commonly seats about 8–10 passengers and typically has somewhat shorter range than the larger AW139/H160 class, though it can be optimized with auxiliary fuel. Actual figures vary with cabin layout, fuel options, IFR reserves, and mission equipment.
