Viking developed the Guardian 400 in response to worldwide military and government agency demand for a medium-range maritime patrol, SAR and critical infrastructure platform based on the new Twin Otter Series 400 aircraft. Designed as an economical force multiplier for 21st century surveillance and security requirements, the Guardian 400’s low acquisition and operating costs combined with its modern, flexible sensor architecture allows it to be customized to suit operators’ financial and mission requirements.
Special Mission Aircraft
The Guardian 400 is the only special mission aircraft capable of operating on five different types of landing gear, including amphibious or straight floats, wheel skis, intermediate flotation gear for off strip operations, and/or standard wheel gear, allowing the Guardian 400 the unique opportunity to provide on-site interdiction or rescue while conducting surveillance.
The Guardian 400’s robust design, minimal maintenance requirements, and exceptional short-field performance capabilities make it ideally suited for specialized government operations in extreme environments. Certified under the restricted category, the Guardian 400’s increased take-off weight and ultra long-range wing tanks allow for operational sorties over 10 hours in duration.
Trusted by the governments of Peru, Panama, the United States, United Arab Emirates, and Vietnam, over thirty Twin Otter Guardian 400 aircraft have now entered service in various roles, including maritime surveillance, search & rescue, parachute operations, pipeline monitoring, drug enforcement, medevac, and critical infrastructure support.
