Bell 525 Relentless vs Leonardo Aw189 vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Sikorsky S 92

Bell’s 525 Relentless, Leonardo’s AW189, and Sikorsky’s S-92 are all modern, twin‑engine, IFR-capable medium helicopters aimed at offshore transport, corporate/VIP, and SAR-style missions, while the MD Helicopters 902 Explorer is a lighter twin used more for law-enforcement, EMS, and utility roles with lower acquisition and operating footprints. In range, the S-92 and AW189 generally sit at the higher end for typical offshore missions, with the 525 also designed for strong legs in the same class; the MD 902’s practical range is notably shorter than the three medium twins. Passenger capacity follows the same pattern: the S-92 is commonly configured for the most seats in transport layouts (often around 19), the AW189 and Bell 525 typically carry fewer but still “medium-class” loads (commonly in the mid-to-high teens depending on interior and mission), and the MD 902 is usually in the single digits to low teens depending on configuration, with much less cabin volume than the others. Overall, MD 902 fits light-twin needs; 525/AW189/S-92 compete for medium offshore and high-payload missions, with S-92 often leading on maximum people-moving.
