Airbus Helicopters H145 vs Airbus Helicopters H175 vs Airbus Helicopters H215 vs Bell 525 Relentless

The Airbus H145 is a light twin-engine helicopter best suited to short- to medium-range missions such as HEMS, law enforcement, and utility work. It typically carries around 6 to 9 passengers (depending on configuration) and offers the shortest range of this group, generally in the mid-hundreds of nautical miles. The Airbus H175 and Bell 525 Relentless sit in the super‑medium class, aimed at offshore transport and longer-range SAR/utility roles. Both offer substantially greater range than the H145 and commonly accommodate roughly 12 to 16 passengers in offshore-style seating. In broad terms, their ranges are typically around the 400–500+ nautical mile class depending on payload, reserves, and cabin fit. The Airbus H215 is a heavy helicopter derived from the Super Puma family, prioritizing lifting capability and robust utility/offshore performance. It usually carries the most passengers of the four, often around 16 to 19 in transport layouts, with range generally comparable to, or slightly below, the super‑mediums depending on configuration, but with stronger payload capability.
