Airbus Helicopters H225 vs Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Gulfstream G700

The Airbus H225 and Bell 525 Relentless are large, long-range helicopters suited to offshore transport and VIP missions; both typically carry around 16–20 passengers depending on configuration, with ranges roughly in the 500–600+ nautical mile class, and the H225 generally emphasizing proven heavy-lift/offshore capability while the 525 targets high-speed, modern avionics, and efficient operations in the super-medium category. The Cessna 208B Grand Caravan EX is a single‑engine turboprop utility airplane optimized for short, rugged routes; it commonly seats about 9–14 passengers and offers a practical range around 800–900 nautical miles depending on payload and reserves. The Gulfstream G700 is an ultra‑long‑range business jet designed for intercontinental travel; it typically carries 12–19 passengers in executive layouts (with higher maximums possible) and delivers approximately 7,500 nautical miles of range, far exceeding the others while operating at much higher speed and altitude. Overall, the helicopters prioritize vertical access and flexible landing sites, the Caravan prioritizes simplicity and short-field utility, and the G700 prioritizes speed, comfort, and global reach.
