The CTS800 has also been selected as the boundary layer compressor drive for the ShinMaywa US-2 amphibious search and rescue aircraft. A CTS800-powered version of the Agusta A129 attack helicopter first flew in 1988, this engine being offered for both new A129 sales and fleet upgrades.
The CTS800 also powers the next generation of AgustaWestland Super Lynx aircraft, having first flown in the Lynx in 1991. The CTS800-powered Super Lynx is now in service with militaries worldwide, with the engine also being offered as an upgrade for existing Lynx fleets.
