Airbus Helicopters H175 vs Airbus Helicopters H225 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw189

Airbus Helicopters H175 and Leonardo AW189 sit in the “super-medium” class, typically configured around 16–19 passengers, balancing cabin volume with long overwater legs; their practical mission ranges are broadly comparable, with the AW189 often advertised with slightly stronger long-range capability in offshore fit while the H175 is commonly positioned similarly for North Sea–style sectors. The Leonardo AW139 is a “medium” helicopter with a smaller cabin and usually about 12–15 passengers in offshore/commercial layouts; its range is generally shorter than the super-medium pair, though it remains highly versatile and efficient for regional and shuttle work. The Airbus Helicopters H225 is a “heavy” twin with the largest cabin of this group and commonly the highest passenger counts (often around 19+ in offshore seating), and it is typically selected when payload and cabin volume matter most; range can be competitive but is often traded against higher lift capability. The Bell 525 Relentless is a newer “super-medium” design aimed at the H175/AW189 segment, generally targeting similar passenger capacities and long-range offshore performance, with configurations and achieved ranges depending on certification status and operator fit.
