Airbus Helicopters H125 vs Airbus Helicopters H145 vs Airbus Helicopters H175 vs Leonardo Aw139

The Airbus H125 is a light single‑engine utility helicopter typically used for short‑ to medium‑range missions. It generally carries a pilot plus up to about five to six passengers depending on configuration and weight, with a range on the order of roughly 330–350 nautical miles. The Airbus H145 is a light twin that sits a step up in category and mission flexibility, offering higher redundancy and a larger cabin. It commonly seats one to two pilots with around seven to nine passengers, and its typical range is broadly similar to, or modestly greater than, the H125 at roughly 330–360 nautical miles depending on variant and fit. The Airbus H175 is a super‑medium twin aimed at offshore and longer‑range transport. It usually accommodates about 12–16 passengers and offers a notably longer typical range, often around 450–500 nautical miles. The Leonardo AW139 is a medium twin and a close peer to the H175 in role, though generally a size class below “super‑medium.” It commonly carries around 12–15 passengers and typically offers range in the neighborhood of 450–550 nautical miles depending on tanks, payload, and mission equipment.
