Airbus Helicopters H225 vs Bell 525 Relentless vs Gulfstream G700

The Airbus H225 and Bell 525 Relentless are large helicopters, typically used for offshore energy, search and rescue, and VIP transport, while the Gulfstream G700 is an ultra-long-range business jet designed for high-speed intercontinental travel. In range, the G700 is in a different class, capable of roughly 7,000+ nautical miles (about 12,000–13,000 km) depending on mission profile, enabling nonstop flights such as New York to Dubai. The H225 and Bell 525 offer ranges in the low-hundreds of nautical miles; the H225 is commonly cited around the mid- to high-400 nm class, while the Bell 525 is generally in a similar bracket, often quoted around the 500 nm class, varying with payload and reserves. For passenger capacity, the helicopters can carry more people in high-density configurations: the H225 is often configured for around 19 passengers (and can be higher in some layouts), while the Bell 525 is typically around 16. The G700 is usually configured for about 12–19 passengers in executive layouts, prioritizing space and comfort over maximum seats.
