Airbus Helicopters H175 vs Airbus Helicopters H215 vs Bell 525 Relentless vs Leonardo Aw139

The Airbus Helicopters H175 and Leonardo AW139 sit in the modern medium twin category, commonly used for offshore transport, SAR, and corporate/VIP work. In range, both are broadly comparable for typical offshore sectors, with the H175 often marketed with strong endurance and payload flexibility, while the AW139 is frequently optimized around high cruise speed and mission versatility; real-world range varies notably by cabin fit, reserves, and payload. Passenger capacity is similar: both are typically configured around 12–16 passengers depending on layout and regulations. The Airbus Helicopters H215 is a heavier, “super-medium” twin derived from the Super Puma family, generally offering more cabin volume and higher payload capability than H175/AW139-class aircraft, and it is often selected when operators want more seats and lifting power; typical passenger configurations can reach roughly 19, with mission equipment affecting this. Its range is generally competitive for offshore and utility missions but is highly configuration-dependent. The Bell 525 Relentless is a newer-generation super-medium twin aimed at the same higher-capability segment as the H215, targeting long-range offshore missions with a large cabin; typical seating is in the mid-to-high teens, again driven by configuration.
