Leonardo Aw139 vs Sikorsky S 92

The Leonardo AW139 and Sikorsky S-92 are both twin‑engine, medium class helicopters commonly used for offshore transport, search and rescue, and government or VIP missions, but they sit in different weight and capability brackets. The AW139 is generally considered a medium twin, optimized for flexibility and operating cost, while the S-92 is a heavier medium helicopter designed for higher payloads and longer offshore legs. In range terms, the AW139 typically supports medium-range missions and is often selected for shorter to mid-length offshore runs or multi-role utility work, whereas the S-92 is usually chosen when operators need longer legs with meaningful reserves and mission equipment, making it a frequent pick for deepwater offshore operations. For passenger capacity, the AW139 commonly carries around 12 to 15 passengers in typical offshore or utility configurations, while the S-92 is generally configured for larger loads, often around 19 passengers, with more cabin volume and baggage capability to match.
