The Airbus Helicopters H225 (previously Eurocopter EC225 Super Puma) is a long-range passenger transport helicopter developed by Eurocopter as the next generation of the civilian Super Puma family. It is a twin-engined aircraft that can carry up to 24 passengers, two crew members, and a cabin attendant. The helicopter is marketed for use in offshore support, VIP passenger transport, and public service missions. Airbus H225 Super Puma is one of the most expensive helicopters at $27 million.

The helicopter is powered by two Turbomeca Makila 2A1 turboshaft engines mounted above the cabin; these engines have 14% more engine power and a redundant dual-channel full authority digital engine control (FADEC) system for high reliability; a backup system is present in the event that both FADEC systems fail. The FADEC system ensures that engine power is always kept within the gearbox's limits. Many of the mechanical components, particularly the engines, were designed to be modular to facilitate maintenance, and composite materials were used to reduce the aircraft's weight wherever possible.

The AgustaWestland AW101 is a medium-lift helicopter used in both military and civil applications. It was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter and first flew in 1987. Several operators, including the armed forces of the United Kingdom, Denmark, and Portugal, call their AW101 aircraft Merlin. It is made in factories in Yeovil, England, and Vergiate, Italy, with licensed assembly work also done in Japan and the United States.

Prior to 2007, the aircraft was sold under the registration EH101. The original designation was EHI 01, after the Anglo-Italian joint venture's name – European Helicopter Industries – but a transcription error changed this to EH101. Westland Helicopters and Agusta merged to form AgustaWestland in 2000, giving rise to the type's current designation.

The AW101 was introduced in 1999 and has since replaced several older helicopter types, including the Sikorsky Sea King, in roles such as medium-sized transport, anti-submarine warfare, search and rescue, and ship-based utility operations. For air-sea rescue, the Royal Canadian Air Force (RCAF) uses the CH-149 Cormorant variant. Another variant, the Lockheed Martin VH-71 Kestrel, was built for the US presidential transport fleet before the program was canceled and the planes were sold. The AW101 is used by civil operators to transport passengers and VIPs. The type has been used in active combat zones, such as in support of coalition forces during the Iraq and Afghanistan wars.
