Airbus Helicopters H175 vs Leonardo Aw139 vs Leonardo Aw189

The Airbus Helicopters H175, Leonardo AW139, and Leonardo AW189 are all medium-class twin‑engine helicopters, but they sit in slightly different size and mission bands. The AW139 is generally considered the lighter, “medium” category option, optimized for fast regional transport, offshore support, and EMS-style missions, with typical seating around 12 to 15 passengers depending on layout. The H175 is a larger medium helicopter often positioned toward the “super‑medium” end of the segment; it typically carries roughly 16 to 18 passengers in high‑density configurations and is commonly selected for offshore and long-range passenger transport. The AW189 is also a super‑medium and is comparable in overall role to the H175, with typical passenger seating around 16 to 19. For range, all three are designed for substantial offshore legs, but the AW139 generally offers the shortest range of the group, while the H175 and AW189 typically provide longer ranges with similar long‑leg capabilities, depending heavily on fuel tank configuration, payload, reserves, and mission profile. In practice, AW139 suits medium-range routes with smaller groups, while H175 and AW189 better fit longer legs and higher passenger counts.
