AW101

The AW101 began as the EH101, a joint British-Italian helicopter program intended to replace older naval and transport helicopters with a larger, modern platform. Leonardo describes it as a versatile multi-role helicopter, and a company feature notes its development by Agusta and Westland before the later Leonardo consolidation. The aircraft's three-engine layout and large cabin gave it enough performance margin for naval, battlefield, search-and-rescue, and special-mission use.

AW101 design is built around payload and mission flexibility. Leonardo highlights maritime, battlefield, personnel recovery, and search-and-rescue configurations, all based on a common platform. The aircraft's cabin volume, side door, rear ramp, and high power margin allow operators to fit sonar, radar, rescue equipment, troops, cargo, or medical systems without changing to a different helicopter family.

In service, AW101 has been ordered by countries including the United Kingdom, Italy, Portugal, Denmark, Canada, Japan, and Norway. Its importance comes from adaptability: the same broad airframe supports anti-submarine warfare, troop lift, combat search and rescue, maritime patrol support, and government transport. That makes AW101 a useful example of a high-end helicopter designed for mission breadth rather than a single narrow battlefield role.
