Airbus Helicopters H175 vs Bell 525 Relentless vs Gulfstream G700 vs Leonardo Aw139 vs Leonardo Aw189 vs Sikorsky S 76d

Airbus Helicopters’ H175 is a super-medium helicopter, typically configured for about 16 passengers, with a practical range on the order of roughly 600–700 nm depending on fit and reserves. Bell’s 525 Relentless is a large, long-range helicopter in a similar mission space, generally seating around 16–19 passengers, with range commonly cited around the 500–600+ nm class. Leonardo’s AW139 is a medium twin, often set up for about 12–15 passengers, with range usually in the ~500–600 nm bracket. Leonardo’s AW189 is a larger “super-medium,” typically around 16–19 passengers, with range broadly similar to or slightly higher than AW139/H175 depending on configuration, commonly ~600–700 nm class. Sikorsky’s S-76D is a medium helicopter optimized for corporate/EMS and offshore support, usually carrying about 8–12 passengers, with range often around ~400–500 nm. Gulfstream’s G700 is a large-cabin business jet, not a helicopter, and sits in a different category entirely: it carries roughly 13–19 passengers in typical layouts and offers intercontinental range of about 7,500 nm, far exceeding the rotorcraft listed.
