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

The Airbus H225 and Bell 525 Relentless are large, long-range twin‑engine helicopters aimed at offshore transport, SAR, and high‑end utility missions, while the Cessna 208B Grand Caravan EX is a single‑engine turboprop fixed‑wing aircraft optimized for rugged regional hauling. In category terms, the H225 is a proven heavy/“super‑medium” class rotorcraft with strong lift and established offshore credentials; the Bell 525 is a newer super‑medium design emphasizing speed, modern avionics, and efficient long legs. The Grand Caravan EX sits in a different niche: simpler, lower operating complexity, and best where runways (even short or unimproved) are available rather than vertical lift. On range, both helicopters generally deliver long offshore-style reach, with the H225 typically around the mid‑400 nautical mile class and the Bell 525 targeting roughly the 500–600+ nautical mile class depending on fit and reserves, whereas the Caravan EX commonly reaches roughly 900–1,000+ nautical miles with reserves, benefiting from fixed‑wing efficiency. For passenger capacity, the H225 is commonly configured around 16–19 passengers, the Bell 525 about 16–20, and the 208B typically up to 9 passengers.
