The CL-327 Guardian is a reconnaissance Unmanned Aerial Vehicle (UAV) developed by the Canadian firm Bombardier. It represents a modernized version of the CL-227 Sentinel, an aircraft designed by Canadair for the U.S. Navy and tested in 1988 aboard the USS Vandergrift frigate.
Advanced Features and Design
This UAV is distinguished by its vertical take-off and landing (VTOL) capability, powered by a Williams International WTS-125 gas turbine engine. It is designed for reconnaissance and surveillance missions, both maritime and land-based, as well as for target classification and designation.
The CL-327 Guardian also performs communication functions and maritime border patrol. For these purposes, it is equipped with combined IR/optical sensors, active Electronic Intelligence (ELINT) systems, and a radar with Synthetic Aperture Radar (SAR) capabilities.
Production and Strategic Deployment
Serial production of the CL-327 Guardian began in 1996, with deliveries to the U.S. Navy commencing in 1998. After 2000, deliveries of this advanced UAV were also planned for other NATO member navies, reinforcing its role in aerial surveillance.
