The selection process considered technical, operational, and economic factors, aiming to ensure that the next generation of French naval aviators receives training on a platform that mirrors the technological environment of modern combat aircraft.

This article explores the historical significance of the Falcon 10MER, the reasons for its replacement, the capabilities of the Pilatus PC-24, and the broader implications for French naval aviation and defense strategy.

Historical Context and Background of the Falcon 10MER Program

The relationship between the French Navy and the Dassault Falcon 10 began in 1975 when the service introduced seven specially designated Falcon 10MER aircraft to address a critical gap in naval pilot training capabilities. The “MER” designation stood for “Marine Entraînement Radar,” translating to “Navy Radar-Systems Training,” which precisely defined the aircraft’s primary mission within French Naval Aviation. This acquisition came at a time when the French Navy recognized the need for a dedicated training platform that could bridge the gap between basic flight instruction and the complex operational requirements of carrier-based fighter aircraft.

The selection of the Falcon 10 was driven by pragmatic considerations rather than extensive military modifications. As Frégate Captain François Daylaud, commanding officer of Escadrille 57S, noted, nothing distinguishes a Falcon 10 Mer from a civilian version except the gray and white livery it has worn since entering service in 1975. This approach reflected the French Navy’s practical philosophy, as the service determined that the civilian aircraft’s standard configuration already met their operational requirements without requiring costly military-specific modifications. The aircraft’s utilization within naval forces, particularly within Escadrille 57S, did not require any specific modifications because the main mission remained focused on training shipboard fighter pilots on instrument procedures and French military flight protocols.

Escadrille 57S itself carries a distinguished heritage dating back to World War I, when it was originally established on May 10, 1915, as Escadrille MS 57 of the French Air Force. The squadron underwent several transformations throughout the 20th century, including service during the Battle of France and operations in French Algeria, before being reformed as part of the French Navy Aéronavale in 1953. The unit was reconstituted at BAN Landivisiau on September 1, 1981, under Lieutenant Guy Baillot, initially operating Morane-Saulnier MS.760 Paris aircraft alongside early models of the Dassault Falcon 10. This historical continuity demonstrates the squadron’s adaptability and enduring importance within French naval aviation Training structures.

The Falcon 10 program represented Dassault Aviation’s entry into the light business jet market during the early 1970s. Despite its numerical designation suggesting it preceded the Falcon 20, the Falcon 10 was actually developed afterward as a smaller, more economical alternative. The aircraft featured a completely redesigned non-circular fuselage, new wing configuration with slotted flaps, and simplified systems compared to its larger sibling. Production began in 1971 and continued until 1989, establishing the platform as a popular choice in the second-hand business jet market. By 2018, Falcon 10s from the 1970s were priced between $300,000 and $600,000, reflecting their enduring value despite their age.

The Aging Fleet Challenge and Replacement Decision

After more than four decades of continuous service, the French Navy’s Falcon 10MER fleet began showing significant signs of aging that ultimately necessitated replacement considerations. Captain Daylaud acknowledged that the aircraft “is indeed showing its age,” adding that the platform “will not be able to withstand a more important transformation project, in particular the installation of ADS-B or CPDLC.” The complexity of implementing these modern aviation communication and surveillance systems would require expenses greater than acquiring four new aircraft, making modernization economically unfeasible.

The availability of spare parts became increasingly problematic as the aircraft aged, despite Dassault’s continued remote monitoring support and technical assistance when necessary. This maintenance challenge is common among aircraft that have been out of production for over three decades, as manufacturing support networks naturally diminish over time. The French Navy maintained a satisfactory availability rate through the expertise of three Navy technicians who conducted airworthiness checks, but the long-term sustainability of this approach became questionable.

Beyond maintenance concerns, operational requirements continued evolving in ways that the 1970s-era Falcon 10 could not accommodate. Modern aviation regulations increasingly demand sophisticated communication systems, surveillance technologies, and navigation capabilities that would require substantial aircraft modifications. The French Navy’s assessment concluded that implementing these upgrades would exceed the cost of procuring replacement aircraft while providing limited operational improvement.

The Navy’s systematic evaluation process identified specific performance criteria that potential replacement aircraft needed to meet. Speed requirements, while important, proved less critical than previously assumed, as the evaluation determined that replacement aircraft did not necessarily need to match the Falcon 10’s velocity performance. Instead, the focus shifted toward avionics compatibility with current French military systems, particularly alignment with Rafale fighter aircraft instrumentation to enhance training effectiveness.

With these considerations in mind, the Navy commenced studies for a successor aircraft several months before making a final decision, establishing a project deadline of 2025 as the point when state airworthiness waivers for the Falcon 10 Mer would expire. This timeline created urgency around the replacement decision while ensuring adequate lead time for procurement and integration of new aircraft into training operations.

Technical Analysis of the Selected Pilatus PC-24

The Pilatus PC-24 represents Switzerland’s entry into the light business jet market and embodies several unique characteristics that distinguished it during the French Navy’s selection process. Following Pilatus Aircraft’s success with the PC-12 single-engine turboprop, development work on the twin-engine jet began in 2007 with goals of achieving greater range and speed while maintaining the company’s signature rough-field operational capability. The aircraft was officially introduced on May 21, 2013, and completed its maiden flight on May 11, 2015, before receiving EASA and FAA type Certification on December 7, 2017.

The PC-24’s performance specifications demonstrate capabilities that align closely with French Navy training requirements. The aircraft measures 55 feet, two inches in length with a wingspan of 55 feet, nine inches, and stands 17 feet, four inches high. Its maximum takeoff weight of 18,700 pounds supports a typical cruise speed of 440 knots and a range of 2,000 nautical miles. The service ceiling of 45,000 feet provides operational flexibility for various training scenarios. Two Williams FJ44-4A turbofan engines power the aircraft, each providing 3,400 pounds of thrust while consuming approximately 160 gallons of fuel per hour.

The cabin configuration offers significant advantages for training operations, accommodating up to ten passengers with three exits including a cargo door on the left side of the fuselage capable of handling standard pallets. This flexibility proves valuable for both training missions and the logistical support roles that the French Navy requires from its utility aircraft. The PC-24’s internal baggage volume of 90 cubic feet substantially exceeds many competitors, though it lacks external baggage space.

One of the PC-24’s most distinctive features is its certified capability to operate from unpaved runway surfaces, a characteristic that sets it apart from virtually all other business jets in its class. The aircraft received European and US certification for operations on dry sand and gravel runways in the fourth quarter of 2018, followed by approval for grass, wet earth, and snow-covered surfaces in February 2020. This rough-field capability results from specialized design elements including long-stroke trailing link landing gear and main wheels pressurized to only 70 psi to prevent sinking on soft surfaces. The wing features replaceable flap surfaces that shield engines from debris during gravel runway operations.

The avionics suite centers on the Honeywell Primus Epic 2 system featuring the Advanced Cockpit Environment, which enables single-pilot operations. Newer PC-24 variants incorporate touchscreen-controlled displays and additional avionics upgrades that align with modern aviation standards. These systems include synthetic vision technology, auto-throttle, graphical flight planning, traffic collision avoidance systems, and LPV guidance capability. The intuitive cockpit design features four 12-inch screens and an inertial reference system providing reliable altitude and navigation data.

The PC-24 is the only business jet certified for operations from grass, gravel, sand, and snow runways, offering unmatched flexibility for military and austere environments.

Financial Considerations and Aircraft Procurement Economics

The economic aspects of the French Navy’s PC-24 acquisition reflect broader trends in military aircraft procurement, where lifecycle costs increasingly influence selection decisions beyond initial purchase prices. According to multiple industry sources, a new Pilatus PC-24 typically costs approximately $13 million, though prices have varied from $10.7 million to $13 million depending on configuration and Delivery timing. In 2023, the equipped price reached $12.2 million, reflecting ongoing inflation in aerospace manufacturing costs.

The total acquisition cost for three PC-24 aircraft would therefore represent an investment of approximately $36-39 million for the French Navy, assuming standard civilian configurations with minimal military-specific modifications. This figure excludes potential customization costs for French military communication systems, livery applications, and any specialized training equipment integration that might be required.

Operating cost comparisons reveal the PC-24’s economic efficiency relative to other aircraft in its class. Annual operating costs range from just under $1 million to approximately $1.5 million depending on utilization rates. Fixed costs including crew payments, training, hangar rental, insurance, and aircraft management typically account for under $300,000 annually. Variable costs correlate directly with flight hours, with aircraft flying 200 hours annually incurring approximately $625,000 in variable expenses, while 400-hour annual utilization reaches around $1.25 million.

These operating economics compare favorably with the Embraer Phenom 300E, which the French Navy also considered during its evaluation process. Cost-per-mile analysis shows the Phenom 300E at $4.75 per nautical mile compared to the PC-24’s $4.92, representing a modest 3.5% advantage for the Brazilian aircraft. However, the PC-24’s superior cabin volume and significantly greater internal baggage capacity provide operational advantages that likely influenced the French Navy’s decision.

The PC-24’s market positioning reflects strong demand within the light business jet segment. Pilatus sold the initial production run of 84 units within 36 hours of opening orders at the May 2014 EBACE show, with deliveries scheduled through early 2020. When orders reopened in May 2019, approximately half of 80 available delivery positions sold within days at a price of $10.7 million each. The company delivered its 50th aircraft by October 2019 and the 100th by January 2021, demonstrating consistent production momentum.

Strategic and Operational Implications for French Naval Aviation

The transition from Falcon 10MER to PC-24 aircraft represents more than a simple equipment replacement; it reflects the French Navy’s broader modernization strategy and evolving training requirements for naval aviators. The decision aligns with contemporary naval aviation trends emphasizing advanced avionics integration, operational flexibility, and cost-effective training solutions that prepare pilots for increasingly sophisticated combat aircraft.

Captain Daylaud emphasized the continuing importance of instrument flight rule (IFR) training for French naval pilots, noting that “pilots on the Rafale come to us three times a year to validate their knowledge of IFR instrument flight.” This requirement underscores the critical role that Escadrille 57S plays in maintaining pilot proficiency across the French naval aviation community. The PC-24’s modern avionics suite, which more closely resembles systems found in contemporary military aircraft like the Rafale, should enhance training effectiveness compared to the 1970s-era Falcon 10 instrumentation.

The new aircraft’s rough-field capability provides operational advantages that extend beyond the Navy’s primary training mission. French military operations increasingly occur in austere environments where conventional runway infrastructure may be unavailable or compromised. The PC-24’s certified ability to operate from grass, gravel, sand, and even snow-covered surfaces gives commanders additional flexibility for logistics, personnel transport, and emergency operations that the Falcon 10 could not provide.

Training efficiency should improve through the PC-24’s enhanced cabin configuration and instrumentation. The aircraft’s larger passenger capacity allows for more comprehensive crew training scenarios, while the modern cockpit environment better prepares pilots for transition to current-generation military aircraft. As Captain Daylaud noted, the proximity of instructor to student remains crucial for effective training, and the PC-24 maintains this advantage while providing updated systems familiarization.

The timing of this replacement coincides with broader French Naval Aviation modernization efforts that extend through 2045. Recent strategic planning documents indicate the French Navy is preparing for significant changes in carrier air wing composition, including integration of unmanned aerial vehicles and next-generation fighter aircraft. The PC-24’s modern avionics and systems architecture position it to support training requirements for these future capabilities more effectively than the aging Falcon 10 fleet.

Conclusion

The French Navy’s selection of the Pilatus PC-24 to replace its aging Falcon 10MER fleet represents a well-considered modernization decision that balances operational requirements, economic considerations, and strategic objectives within the broader context of French military transformation. After 45 years of faithful service, the Falcon 10MER aircraft have reached the limits of their operational viability, with aging systems, spare parts availability challenges, and inability to accommodate modern avionics upgrades necessitating replacement.

The PC-24 selection process demonstrates mature procurement decision-making that prioritized operational effectiveness over pure performance metrics. The French Navy’s recognition that replacement aircraft need not match the Falcon 10’s speed capabilities, but should provide avionics compatibility with current operational fleet systems, reflects sophisticated understanding of modern training requirements. The chosen platform’s rough-field capabilities, advanced cockpit systems, and superior cabin configuration provide operational advantages that extend well beyond the basic training mission.
