Airbus Helicopters H175 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw139 vs Sikorsky S 76d vs Sikorsky S 92

Airbus Helicopters’ H175 and H225, Sikorsky’s S-92, Bell’s 525 Relentless, and Leonardo’s AW139 are generally in the medium to super‑medium class used for offshore and utility missions, while the Sikorsky S‑76D is a lighter medium twin optimized for executive and short‑to‑mid range transport. In passenger capacity, the H225 and S‑92 typically sit at the top for the group, often configured around 16–19 passengers (and can be arranged for more in high‑density layouts), making them common for heavy offshore crew changes. The H175, AW139, and Bell 525 generally cluster slightly below that in typical offshore layouts, often around 12–16 passengers, balancing payload and cabin size with operating economics. The S‑76D usually carries fewer, commonly around 8–12 depending on configuration. For range, all are capable of several hundred nautical miles, but the offshore‑oriented super‑medium/heavy types (H225 and S‑92) and the new‑generation 525 are typically positioned for longer legs and endurance, with the H175 and AW139 close behind; the S‑76D generally offers shorter range than the larger offshore machines, though still substantial for regional and corporate missions.
