Airbus Helicopters H155 vs Airbus Helicopters H175 vs Bell 525 Relentless vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 92

The Airbus Helicopters H155 is a light twin in the 4–5 ton class, typically used for corporate/EMS and shorter offshore legs; practical range is roughly in the 450–650 km band depending on fit, with about 8–12 passengers in a high-density layout (often fewer in VIP/EMS). The Leonardo AW139 sits in the medium twin category around 6–7 tons, optimized for utility and regional offshore work; typical range is about 700–1,000 km, with roughly 12–15 passengers. The Bell 525 Relentless is a super-medium twin, aimed at longer, faster offshore missions; typical range is about 900–1,200 km, carrying around 16 passengers. The Airbus H175 is also a super-medium twin, comparable mission set and scale; typical range is about 1,000–1,300 km with roughly 16 passengers. The Leonardo AW189 is a heavier super-medium, designed for longer-range offshore and SAR; typical range is about 900–1,200 km with about 16–19 passengers. The Sikorsky S-92 is a heavy twin in the 11–12 ton class for demanding offshore and SAR; typical range is about 800–1,100 km with roughly 19 passengers.
