AgustaWestland AW159 Wildcat

The AgustaWestland AW159 Wildcat (previously called the Future Lynx and Lynx Wildcat) is an improved version of the Westland Super Lynx military helicopter designed to serve in the battlefield utility, search and rescue and anti-surface warfare roles. In British service, common variants are being operated by both the Royal Navy and British Army to replace their ageing Lynx Mk.7/8/9 rotorcraft. The AW159 has also been offered to several export customers, including the Republic of Korea Navy which placed an order for 8 in 2013.

The AW159 Wildcat is the successor to, and a further development of, the Westland Lynx. While the AW159 shares broad similarities in appearance to the Lynx, it has significant design differences and is heavily modernised and adapted to gain new attributes and functionality. The AW159 comprises 95% new components; the remaining 5%, consisting of such items as the fuel system and main rotor gearbox, are interchangeable with the Lynx AH7 and HMA8 variants. The AW159 is the first helicopter by AgustaWestland to be designed inside an entirely digital environment. Among other changes, certain external elements of the Wildcat, such as the tail rotor, have been redesigned for greater durability and stealth qualities.

Both Army and Navy variants are based on a common airframe, which is suitable for marine use and equipped with a wheeled undercarriage. The AW159 is powered by two 1,362 hp (1,016 kW) LHTEC CTS800 turboshaft engines, and has a new composite tailboom, tailplane, tail rotor, nose structure and avionics suite. The naval version is also equipped with a SELEX Galileo Seaspray 7000E active electronically scanned array (AESA) radar and L-3 Wescam MX-15Di electro-optical/infrared nose turret.

KEY FEATURES

AESA technology and flexible waveform generation capability enables Seaspray 7000E to deliver peak performance in all modes.

Use of multiple low power, solid state Transmit/Receive Modules (TRM) makes the Seaspray 7000E radar more reliable than conventional radar systems. This results in a significant cost benefit over the life of the system. Superior performance in detecting small targets, such as Fast Inshore Attack Craft (FIAC) in high sea states, through use of composite mechanical and electronic scanning.

Interleaved modes by virtue of its ability to change waveforms pulse-to-pulse. For instance, surface surveillance and weather detection can be provided simultaneously. Effectively two radars within one system. Comprising just two primary air cooled Line Replaceable Units (LRU) and requiring no waveguide, Seaspray 7000E is easy to install.

Seaspray 7000E can be provided as a turnkey solution with embedded navigation sensors and Human Machine Interface (HMI) or as a sensor solution to integrate with a platform mission system using industry standard interfaces.

Key Benefits

  • Excellent performance
  • Low cost of ownership
  • True multi-mode operation
  • Superior reliability, enabling mission success
  • Ease of installation
  • Easy to use
  • Mode interleaving
  • Flexible system integration options.

South Korea receives first batch of AW159 anti-submarine helicopters: Here

Besides ASW sensors, the helicopter can also be armed with lightweight torpedoes, such as the K745 Cheong Sangeo (Blue Shark), and depth charges to prosecute underwater vessels. Thales confirmed in October 2013 that the RoKN’s AW159 helicopters will be equipped with the company’s Compact FLASH Sonics low-frequency, long-range dipping sonar system. The airframes will also be equipped with the Seaspray 7000E active electronically scanned array radar supplied by Selex.
