The aircraft's initial foray into the American market was facilitated by a strategic distribution agreement with Pan American, a move that saw American-delivered models branded as the 'Fan Jet Falcon.' This moniker quickly evolved into the more familiar 'Falcon 20,' a name that would soon become synonymous with executive air travel.

The demand was immediate and substantial; by 1968, Pan American Business Jets Division had already placed orders for an impressive 160 Falcon 20s. This early success was a harbinger of things to come, as significant orders soon followed from diverse operators, including the French Navy, the United States Coast Guard, and the burgeoning express delivery giant, Federal Express.

Evolution and Adaptation: The Falcon 200 and Beyond

Dassault's commitment to innovation didn't stop with the original Falcon 20. An enhanced model, the Falcon 200, was subsequently developed, featuring Garrett ATF3 engines that significantly boosted its range, capacity, and overall comfort. Recognizing the enduring value of the original design, many early Falcon 20s were retrofitted with more modern Garrett TFE731 turbofan engines, extending their operational life and enhancing their efficiency.

The aircraft's popularity was such that production continued until 1988, a remarkable run that saw it eventually superseded by more advanced iterations within the Falcon family. However, the passage of time brought new challenges, particularly with the increasing implementation of noise-abatement regulations.

To comply with these stricter environmental standards, some Falcon 20s faced operational restrictions or underwent modifications, including the installation of Stage 3 noise-compliant engines or specialized hush kits. Beyond its commercial success, the Falcon 20 also found a niche as a versatile aerial testbed and laboratory for various organizations, including NASA, showcasing its adaptability for scientific and research purposes.

Engineering Excellence: The Heart of the Falcon 20

The design philosophy behind the Dassault Falcon 20 emphasized both aesthetic appeal and superior flight characteristics. Its inherent stability meant that it did not require complex stick pusher or stall-barrier systems to maintain predictable stall behavior. The aircraft's flight controls are hydraulically powered, with mechanical pushrods providing a direct and responsive connection between the cockpit and the flight control surfaces.

In the unlikely event of hydraulic system failure, the aircraft could still be flown manually, a testament to its robust design. An artificial feel system further refined the pilot's experience, optimizing sensations for smooth and precise control.

Powerplant and Performance

Powering the Falcon 20 were primarily rear-mounted turbofan engines, with the General Electric CF700, Garrett TFE731, and ATF3 engines being the most common. The integration of newer engine technologies not only improved the aircraft's range but also enhanced its speed and climb rate. Electronic flight computers played a crucial role in maintaining safe levels of engine power throughout climbs, ensuring optimal performance and safety.

Aerodynamic Design

The aircraft also featured a highly swept wing design, complemented by leading-edge slats that improved slow-speed performance and reduced stalling speed. These slats automatically deployed when approaching a high angle of attack, further enhancing safety and control. Ailerons provided precise control, while a wing root fillet section and a shortened wing fence were incorporated into the Falcon 200 model. Air brakes and hydraulically operated landing gear further contributed to the aircraft's operational efficiency.

A Storied Operational History

Commercial and Corporate Dominance

The Falcon 20 quickly established itself as a dominant force in the commercial and corporate aviation sectors. Early sales in North America were particularly robust. Although the Recession of 1969–70 initially led to a surplus of unsold Falcon 20s, Pan American Business Jets Division actively pursued sales, leading to a recovery in American demand. Dassault subsequently became the primary partner in the venture.

One of the most significant chapters in the Falcon 20's commercial history began with Frederick W. Smith, the visionary founder of Federal Express. Smith recognized the aircraft's potential for his nascent express delivery business. Despite initial financial hurdles, Federal Express acquired several Falcon 20s, converting them for dedicated cargo operations. In September 1972, Federal Express even established an in-house training school to prepare ex-military pilots for these specialized commercial operations.

In April 1973, Federal Express officially launched its air express package delivery service, with Falcon 20s operating from its distribution hub in Memphis, Tennessee. Within three years, the airline had built a nationwide network, largely thanks to the Falcon 20's capabilities. The aircraft's high demand eventually necessitated the introduction of larger cargo aircraft to supplement the fleet. Federal Express ultimately operated a fleet of 33 Falcon 20s.

Guardians of the Coast: The U.S. Coast Guard

The United States Coast Guard (USCG) also recognized the Falcon 20's versatility, operating it under the designation HU-25 Guardian. This high-speed aircraft served as a vital asset for locating shipwreck survivors and for interdicting aerial and shipborne drug trafficking. The first HU-25 was delivered in 1982, and by December 1983, the USCG had acquired a total of 41 aircraft. The HU-25's operational tenure eventually concluded with its replacement by the EADS HC-144 Ocean Sentry, a turboprop-powered aircraft.

The HU-25 played a critical role in drug interdiction missions and was instrumental in detecting oil spills and environmental pollutants. Early HU-25A models were equipped with specialized sensors for oil spill detection. Subsequent upgrades saw HU-25Cs fitted with advanced radar systems, including AN/APG-66(V)2 and AN/APS-143B(V)3, leading to the designations HU-25C+ and HU-25D. After 32 years of dedicated service, the last operational HU-25 Falcon was retired on September 26, 2014.
