Airbus Helicopters H155 vs Leonardo Aw119kx vs Leonardo Aw139

The Airbus Helicopters H155 and Leonardo AW139 are midsize twin‑engine helicopters, while the Leonardo AW119Kx is a light single‑engine helicopter. In typical configurations, the H155 seats about 12–13 passengers, the AW139 about 12–15, and the AW119Kx about 6–7, making the AW119Kx better suited to smaller groups and lower operating complexity, and the H155/AW139 better for higher-capacity transport and multi-role missions. For range, all three can be equipped with different fuel options, so figures vary by payload and reserves, but broadly the AW139 and H155 tend to offer similar mid-to-long mission reach for their class, commonly on the order of roughly 450–600 nautical miles, while the lighter AW119Kx is generally in a comparable but often slightly lower band, around roughly 350–550 nautical miles depending on configuration. Overall, the AW139 typically emphasizes payload and mission flexibility in the midsize segment, the H155 balances cabin comfort and efficiency, and the AW119Kx prioritizes simplicity and cost-effective light utility or passenger work.
