The Vanguard-class is a class of nuclear-powered aircraft carriers in service with the Federal Navy of Nouvelle Alexandrie. Designed and built by the Pontecorvo Firm, the class represents the first operational deployment of Alexandrium-powered magnetohydrodynamic (MHD) propulsion in a capital ship. At 78,000 tonnes full load, the Vanguard-class is smaller than its predecessor, the Susa-class, but incorporates advances in automation, survivability, and air wing integration that represent a generational shift in carrier design. The elimination of traditional propeller-driven propulsion reduces the acoustic signature by approximately 85 percent compared to conventional nuclear carriers, enabling operational profiles previously impossible for vessels of this size. The class's Alexandrium propulsion system is subject to the export control provisions of the Treaty of Fontainebleau on Alexandrium Coordination, restricting potential foreign sales to Treaty signatories and nations granted Most Favored Nation status.
The Vanguard-class operates a drone-centric air wing of 144 aircraft, with unmanned platforms comprising nearly two-thirds of embarked aviation assets. This configuration reflects the Federal Navy's doctrine of networked warfare, in which manned aircraft serve primarily as command nodes coordinating autonomous and semi-autonomous strike platforms. The class incorporates a 30 percent power reserve to accommodate future directed-energy weapons and advanced sensors, while the Modular Integration Architecture permits combat system upgrades without structural modification. FNS Vanguard (CVN-21), the lead ship, completed initial sea trials in I.1750 AN, achieving 33 knots and validating the MHD propulsion concept. Following extended trials that demonstrated speeds exceeding 35 knots, the Cortes Federales approved a four-ship production order in VII.1750 AN. Production of the Susa-class ran to its sixth hull, and Vanguard-class procurement continued after it.
History
Development of the Vanguard-class began in 1738 AN as Project Silent Wave, a classified program to apply Alexandrium reactor and MHD propulsion technology to carrier aviation. The Pontecorvo Firm received the development contract in II.1740 AN, following a competitive evaluation against proposals from ESB Armada. The program faced significant technical challenges, particularly in scaling MHD propulsion to carrier displacement and integrating the Alexandrium-graphene composite armor system. Construction of the prototype, FNS Vanguard (CVN-21), commenced at the Pontecorvo Shipbuilding Yards in III.1745 AN. The Pontecorvo Firm invested NAX€2.4 billion in the prototype's development, with an additional NAX€890 million in government research funding. The vessel was launched in IX.1748 AN.
Sea trials
FNS Vanguard conducted initial sea trials from 10.I.1750 AN to 14.I.1750 AN, approximately 200 kilometers off the coast of Alduria.[1] During these trials, the vessel successfully launched and recovered 847 sorties over four days, including 312 autonomous drone missions. The MHD propulsion system achieved a maximum speed of 33 knots during conservative initial testing, with the acoustic signature reduction validated at 85 percent below conventional carriers. Captain Ricardo Vidal, the commanding officer, reported that enemy submarines would be unable to detect the vessel at ranges where conventional carriers could be heard from 50 kilometers away.
The electromagnetic aircraft launch system demonstrated the capability to accelerate a 25-tonne aircraft from zero to 240 kilometers per hour in 2.3 seconds, with recovery systems bringing aircraft to complete stops within 90 meters. The modular flight deck, measuring 285 meters in operational length with a 68-meter working width, incorporated separate lanes for manned and unmanned aircraft. Automated systems demonstrated the ability to launch reconnaissance drones every 45 seconds during a sustained twelve-hour period.
Extended operational trials continued through VI.1750 AN, during which further MHD system optimization achieved sustained speeds exceeding 35 knots. The vessel accelerated from 10 to 30 knots in 47 seconds, demonstrating throttle response impossible with mechanical propulsion.
Air wing evolution
The initial sea trials employed a reduced air wing of 120 aircraft configured for technology validation: 24 Javelin F-20 Bluestrike fighters, 12 Javelin M-2 Dragoon reconnaissance drones retrofitted for anti-submarine detection, 48 Javelin M-4 SkyPiercer combat drones, and 36 Javelin E-1 Silent Jammer electronic warfare drones. This composition reflected the prototype's original design concept emphasizing drone-heavy operations.
Operational evaluation during extended trials revealed critical capability gaps. The absence of dedicated airborne early warning aircraft, anti-submarine warfare patrol platforms, aerial refueling tankers, and rotary-wing assets limited the air wing's ability to conduct sustained independent operations. The Federal Navy's Carrier Air Wing Requirements Review, completed in V.1750 AN, mandated an expanded and diversified air wing composition for production ships.
The revised standard air wing of 144 aircraft addresses these deficiencies while maintaining the drone-centric operational concept. Manned aircraft now include dedicated AEW and C platforms, ASW patrol aircraft, SIGINT collectors, tankers, and a hypersonic interceptor capability. The rotary-wing component provides close-in ASW coverage, search and rescue, and utility transport. FNS Vanguard underwent modification during late 1750 AN to accommodate the expanded air wing, serving as the validation platform for the production configuration.
Production
The Cortes Federales approved a four-ship production order in VII.1750 AN, following completion of extended operational trials and comprehensive cost-benefit analysis by the Department of Defense. Industry analysts estimated the production cost at NAX€8.2 billion per vessel in a five-ship run, compared to NAX€6.8 billion for the Susa-class. However, the reduced crew size and lower operational costs were projected to offset the higher acquisition price within 15 years of service.
Construction of FNS Sovereign (CVN-22) began at the Wechuahuasi Shipbuilding Complex in II.1751 AN. The production ships incorporate refinements based on prototype testing, including the expanded air wing facilities and improved drone handling systems. FNS Resolute (CVN-23) was laid down at the Pontecorvo Shipbuilding Yards in VIII.1752 AN, with two additional vessels authorized for construction beginning in 1754 AN and 1756 AN.
Design
Hull and propulsion
The Vanguard-class hull measures 318 meters in overall length with a 41-meter waterline beam and 12-meter draft. The flight deck extends 285 meters in operational length with a maximum width of 76 meters, tapering to 68 meters in the primary working area. The island structure stands 32 meters above the waterline, reduced from 45 meters on conventional carriers to decrease radar cross-section and improve stability.
The propulsion system comprises two Alexandrium-239 compact nuclear reactors generating 650 megawatts combined, driving the magnetohydrodynamic (MHD) propulsion system developed under Project Silent Wave. The reactors occupy 40 percent less volume than conventional naval reactors at equivalent output, with a 35-year refueling cycle compared to 20-25 years for previous designs. The Alexandrium-239 fuel assembly maintains 94 percent efficiency compared to 73 percent for conventional naval reactor fuel.
The MHD system eliminates all rotating machinery from the propulsion train. Seawater passes through a magnetic field generated by superconducting coils, with electrical current inducing thrust without mechanical contact. The absence of propellers, reduction gears, and shaft seals produces the 85 percent acoustic signature reduction and enables the instantaneous throttle response demonstrated during trials.
Protection
The Alexandrium-graphene composite armor system provides protection equivalent to twice the thickness of conventional steel armor at 60 percent of the weight. The composite covers the belt, citadel, and flight deck, with the weight savings allocated to enhanced electronic warfare systems and expanded aviation fuel capacity.
Defensive armament includes four RAM launchers for close-in missile defense, three Cerberus Dome close-in weapon systems combining missiles, autocannons, and directed energy, and two ESSM launchers for medium-range air defense. During trials, the defensive systems demonstrated the ability to launch 80 defensive drones in under four minutes, forming autonomous screens that intercepted simulated threats at extended ranges.
Crew and habitability
The ship's complement of 2,400 personnel represents a 35 percent reduction compared to conventional carriers of similar capacity, achieved through extensive automation of damage control, propulsion monitoring, and flight deck operations. The complement comprises 1,720 ship's company and 680 air wing personnel, the latter including flight crews, deck handlers, ordnance specialists, and aviation maintenance technicians.
Crew accommodations incorporate lessons from two decades of carrier operations. Enlisted berthing provides individual sleeping spaces for all personnel, with improved ventilation and noise reduction systems. Medical facilities include two operating theaters and a 40-bed hospital capable of handling mass casualty events.
Longevity and modernization
The class incorporates design features intended to maintain relevance through a projected 50-year service life. The 30 percent power reserve accommodates anticipated directed-energy weapons, advanced sensors, and electronic warfare systems not yet developed. The Modular Integration Architecture permits combat system upgrades without structural modification through standardized interfaces for all sensors, weapons, and command systems.
The flight deck uses a Wechua concrete composite requiring resurfacing every eight years compared to every two years for conventional surfaces. Corrosion-resistant alloys in the propulsion system extend component lifetimes by 40 percent. A planned mid-life modernization at approximately year 20 would install new reactor fuel assemblies, refresh combat systems, and reconfigure drone facilities for next-generation unmanned platforms.
Export restrictions
The Vanguard-class Alexandrium-239 reactor and MHD propulsion system fall under the export control regime established by the Treaty of Fontainebleau on Alexandrium Coordination, signed in 1749 AN. Under the Treaty's provisions, transfer of Alexandrium technology, including propulsion systems incorporating Alexandrium-239 fuel assemblies, requires authorization through the Euran Alexandrium Coordination Organization (EACO). Treaty signatories (Constancia, Nouvelle Alexandrie, Oportia, and Zeed) and Most Favored Nation partners (Natopia and the Benacian Union) qualify as approved purchasers. Any proposed sale to other nations would require unanimous EACO approval, with each member state retaining individual veto authority.
As of 1752 AN, no export variants have been proposed or developed. The Federal Navy of Nouvelle Alexandrie has indicated that technology transfer would be considered only for Raspur Pact allies meeting Treaty requirements.
Air wing
The Vanguard-class operates a standard air wing of 144 aircraft, comprising 40 manned fixed-wing aircraft, 92 unmanned platforms, and 12 rotary-wing aircraft. This composition reflects the Federal Navy's shift toward networked, drone-centric operations while addressing the capability gaps identified during prototype evaluation.
