History

The Westland WG-13 Lynx is a multi-purpose military helicopter designed and built by Westland at its factory in Yeovil. Designed for naval (wheeled landing gear) and battlefield use (skidded landing gear), missions include battlefield utility, anti-armour, search and rescue and anti-submarine warfare roles. From the military WG-13, the larger civil WG-30 was developed.

Capabilities

Production Generations

Lynx

Initial production model, produced in battlefield (skidded undercarriage) and naval (wheeled undercarriage) variants and Gem 2 engines.

Lynx 3

Announced in 1984, the Lynx 3 was an enhanced development, featuring a stretched fuselage, a redesigned tailboom, Gem 60-3/1 engines, a wheeled tricycle undercarriage, BERP rotor blades, and increased fuel capacity. Both battlefield and naval variants were proposed. Cancelled 1987.

Super Lynx

In the early 1990s, Westland incorporated some of the technology from the naval Lynx 3 design into a less-radical Super Lynx. This featured BERP III rotor blades (having a notch toward the outer end of the rotor blade, with a greater amount of sweepback from the notch to the end of the blade compared to inboard of the notch), the Westland 30-derived tail rotor, Gem 42 engines, a new under-nose 360o radar installation and an optional nose-mounted electro-optical sensor turret. Royal Navy Lynx HAS3s upgraded to Super Lynx standard were known in service as the Lynx HMA8, and several export customers ordered new-build or upgraded Super Lynxes. From the 1990s onwards, Westland began offering the Super Lynx 200 (which was equipped with CTS800 engines) and Super Lynx 300, which also had a new (glass) cockpit and avionics derived from the AgustaWestland AW101.

AW159 Wildcat

Advanced Lynx variant based on the Super Lynx 300, with a new tailboom, undercarriage, cockpit, avionics and sensors. Initially referred to as the Future Lynx and later as the Lynx Wildcat, this type has since been re-designated as the AgustaWestland AW159 Wildcat. While having the Lynx as the origins and basis of its design, the Wildcat differs substantially, only 5% of its components, such as the fuel system and main rotor gearbox, remain interchangeable the later variants of the Lynx.
