Maxar Technologies MDA extends industry leadership in unmanned airborne systems for surveillance and intelligence services

Richmond, BC- MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR; TSX: MAXR), announced today that it has signed a contract with an unnamed international customer. MDA will provide turnkey, unmanned aircraft system (UAS) surveillance services. The contract includes options for additional years.

MDA’s UAS service will use a fleet of SchiebelCAMCOPTER® S-100rotary-wing unmanned aircraft to provide surveillance information. MDA will be responsible for all aspects of the service including acquisition of all the systems and required infrastructure, training, airworthiness, logistics, supply chain, maintenance and all flight operations.

The S-100 aircraft is a vertical takeoff and landing UAS, which does not require a prepared area or supporting launch or recovery equipment. It operates day and night and is a very capable platform for a wide range of different surveillance payloads to meet a broad set of mission requirements.

MDA’s UAS service will equip the S-100 fleet withL3 WESCAM MX-10EO/IR payloads. The MX-10 is a high-performance, multi-sensor multi-spectral imaging system for tactical surveillance missions. It carries multiple sensors including both high-definition day modes and night infrared modes. The MX-10 is currently operational for twelve nations worldwide on the S-100 including Naval Shipborne customers leading to a low risk, proven solution.

Mike Greenley, group president of MDA said, “MDA is a global leader and trusted partner in UAS surveillance services in challenging, complex and hostile environments. This program is a key plank in our growth strategy, offering UAS services in many different environments, and for a diverse set of missions.”
