Airbus Helicopters H175 vs Leonardo Aw139 vs Sikorsky S 76d

In category, the Airbus Helicopters H175 and Leonardo AW139 are generally classed as super‑medium, multi‑role twin‑engine helicopters suited to offshore and utility transport, while the Sikorsky S‑76D is typically considered a medium twin oriented more toward corporate/VIP and shorter offshore missions. For range, the H175 and AW139 usually offer broadly similar, longer legs than the S‑76D in typical configurations, making them common choices when payload and distance both matter; the S‑76D’s range is competitive for its class but is generally shorter than the two super‑medium types. For passenger capacity, the H175 and AW139 are commonly configured to carry around 12–15 passengers in transport layouts (with maximum seating higher depending on interior), whereas the S‑76D more often seats about 8–12 passengers, especially in executive or offshore configurations. Overall, H175 and AW139 emphasize higher cabin volume and transport capacity, while the S‑76D prioritizes speed, refinement, and efficient medium‑class operations.
