Airbus Helicopters H225 vs Bell 525 Relentless vs Gulfstream G700 vs Leonardo Aw189

The Airbus H225 and Leonardo AW189 are large, twin‑engine helicopters aimed at offshore transport, SAR, and utility missions, while the Bell 525 Relentless is a newer “super‑medium” twin designed to bridge medium and heavy helicopter roles with modern avionics and cruise efficiency. The Gulfstream G700 is a long‑range business jet in a different category entirely, optimized for high‑speed intercontinental travel rather than vertical lift. In range terms, the G700 is in a separate league, typically capable of roughly 7,000+ nautical miles, enabling nonstop global city pairs. Helicopter ranges are far shorter: the Bell 525 is generally around the 500–600 nm class depending on payload and reserves, the AW189 commonly sits in a similar mid‑hundreds‑of‑nautical‑miles bracket, and the H225 often offers comparable or somewhat higher mission radius in heavy‑lift/offshore configurations, again highly payload‑dependent. For passenger capacity, the G700 typically seats 13–19 in executive layouts. The AW189 and Bell 525 commonly carry about 16–19 passengers in offshore seating. The H225 is usually the highest‑capacity of the helicopters here, often configured around 19 passengers, with some layouts accommodating more for utility roles.
