USCG Retires Fleet of Falcons The Guardian Stands Down The US Coast Guard recently announced the retirement of their fleet of Dassault Falcon 20's; the "HU-25 Guardians". For over 30 years, Falcons have soared the shores as a first line of defense. The Guardian's were based on the French built Dassault Falcon 20, which evolved throughout its 30 plus years of service. Over time, other aircraft were brought online to supplement the Falcons, such as the turboprop HC-144 Ocean Sentry and the HC-27J Spartan, neither of which could match the speed of the Falcon, which is nearly twice as fast as its propeller-driven counterparts. Speed is an essential ingredient in the search and rescue role, as well as keeping pace with high speed aircraft in drug interdiction.
