Bell 525 Relentless vs Leonardo Aw189 vs Leonardo Aw139

The Bell 525 Relentless and Leonardo AW189 sit in a similar “super-medium” class, while the Leonardo AW139 is generally considered a lighter, medium twin. In typical configurations, the Bell 525 targets offshore and corporate missions with a long-legged profile, offering roughly a 1,000 km-class range (mission dependent) and commonly seating around 16 passengers in high-density layouts, with fewer in VIP arrangements. The AW189, also optimized for offshore transport and SAR roles, is usually configured for about 16–19 passengers depending on interior and regulatory fit, and delivers a broadly comparable mission range, often cited around the 900–1,000 km class depending on reserves and payload. The AW139 is the smaller of the three, widely used for EMS, law enforcement, and corporate shuttle; it typically seats about 12–15 passengers and generally posts a shorter range than the two super-medium types, commonly in the ~700–900 km class depending on fuel and load. Exact figures vary significantly with interior, fuel tanks, payload, and operating rules.
