Distributed Sea Denial, formally designated Federal Tactical Doctrine 60-3, is a naval doctrine developed by the Federal Forces of Nouvelle Alexandrie for contesting and denying the use of a maritime area to a stronger adversary through large numbers of attritable unmanned surface vessels. Rather than concentrate combat power in a few costly warships, the doctrine disperses it across many cheap, networked, and individually expendable craft, so that an opponent cannot suppress the threat faster than the Federation can replace it. A reciprocal body of practice, developed in parallel, protects the Federation's own carriers and surface groups against an adversary attempting the same, making the doctrine as much a problem of defending high-value ships as of employing cheap ones.
Background
The Fourth Euran War (1745 AN-1747 AN) and the subsequent Occupation of Oportia carried the same lesson into the maritime domain that the air war had taught ashore: a capital ship, like a crewed strike aircraft, was expensive to build and cheap to threaten. Anti-ship missiles, mines, and fast attack craft could be fielded in numbers that no fleet of exquisite warships could economically answer, and a navy that massed its value in a few hulls presented an adversary with a small number of decisive targets. Analysis by the Department of Defense (Nouvelle Alexandrie) framed the difficulty, as it had for the air defenses that produced Autonomous Saturation, as one of cost-exchange rather than of platform quality.
The doctrine's more direct ancestor was inherited rather than invented. During the Corsair Resurgence of 1744 AN, the Oportian Navy had fought a skirmish campaign in the Shattered Shoals, a contested belt of atolls and submerged reefs, against the fast attack craft and raiding flotillas of the Confederacy of the Dispossessed. The campaign was used as a proving ground for what Oportian planners called distributed maritime engagement tactics, and it tested the real-time data fusion and autonomous targeting systems fitted to the ships of Naval Carrier Group Fouche. Carrier-launched drone squadrons, coordinated strikes combining unmanned aircraft with standoff missiles, and decentralized command under persistent surveillance were exercised against a dispersed and elusive enemy.
That combat experience passed to the Federation with Oportia's accession. Following the dissolution of the old Oportian Security Forces and the constitutionally defensive Oportian Self-Defense Forces that succeeded them, the maritime component was folded into the Federal Forces of Nouvelle Alexandrie in 1755 AN and completed its absorption into the Euran Fleet as the Oportian Squadron. The Federal Navy thereby acquired not only ships and crews but an institutional memory of dispersed, intelligence-driven maritime combat, which the Force 1760 program's investment in unmanned surface and naval systems made it possible to rebuild as a doctrine of its own rather than as the practice of a single task force.
Doctrine
Distributed Sea Denial treats sea control as something to be denied to an adversary before it can be seized for oneself, and it pursues that denial through dispersal rather than concentration. Its elements are the maritime counterpart of the saturation doctrines developed for the air, adapted to the endurance, sea state, and communications problems peculiar to the surface.
Cost-exchange at sea
The doctrine's governing measure, as in Autonomous Saturation, is not the number of enemy ships sunk but the ratio of what the Federation spends to what an adversary must spend to hold a sea area against it. A dispersed force of attritable craft is sized so that clearing it would consume more missiles, sensor effort, and endurance than an opponent can sustain in the contested water, while each craft lost costs the Federation a fraction of a warship. Crewed and high-value units are committed only where the cheaper mass cannot achieve the effect.
The attritable surface swarm
The offensive core of the doctrine is the employment of unmanned surface vessels, principally the Javelin OceanGuard and its derivatives, in numbers and on multiple axes. Configured variously for reconnaissance, decoy work, mine delivery, and strike, the craft are treated as consumable munitions rather than as ships to be preserved. Decoy vessels are sent to be engaged, drawing an adversary's fire and revealing the positions of his sensors and shooters, after which strike craft and loitering munitions exploit the openings. The swarm accepts a rate of loss that no crewed flotilla could bear, trading hulls for the denial effect.
Networked targeting
Coordinating a dispersed force without a central platform is the doctrine's central technical demand, and it is met through the same real-time data fusion first demonstrated by Naval Carrier Group Fouche. Reconnaissance from unmanned craft, maritime patrol aircraft, and shore and satellite sensors is fused into a common picture from which targets are assigned to whichever craft is best placed, with autonomous systems handling engagement geometry that would overwhelm a crewed command. The method is inseparable from control of the electromagnetic spectrum, and the doctrine is developed alongside Silent Spectrum, on which the survival of its data links depends.
Carrier and surface-group defense
The reciprocal of denial is protection, and the doctrine gives equal weight to defending the Federation's own high-value ships against an opponent using the same methods. The carrier and surface groups that the Federal Navy still relies on, formations of the kind that Naval Carrier Group Fouche exemplified, are the natural targets of an adversary's attritable swarm, and the doctrine specifies layered counter-swarm measures, emission discipline, and the dispersal of the group's own escorts so that no single strike can find a concentrated target. The Federation treats the problem of wielding cheap mass and the problem of surviving it as one doctrine seen from two sides.
Implementation
The doctrine is proponent to the Admiralty and is worked up principally within the Euran Fleet, whose Oportian Squadron carries the combat lineage from which it descends. Because the craft are expended in use, the doctrine treats its unmanned inventories as a sustainment problem on the scale of ammunition supply rather than as a fleet to be preserved, procured as consumable munitions under the Force 1760 program's provision for unmanned systems. Draft doctrine was validated by the Joint Warfare Analysis Center through simulation and exercise before promulgation, in the manner prescribed for the Federal Doctrine series, with exercises pairing dispersed unmanned forces against defended surface groups so that both sides of the doctrine were tested at once.
Shore support for the unmanned network is governed by Distributed Littoral Operations, which employs temporary Marine and naval positions for surveillance, communications, maintenance, resupply, and coastal fires.
Distributed Sea Denial is written to interlock with the Federation's other modern doctrines. It shares the cost-exchange logic of Autonomous Saturation and depends on the spectrum dominance that Silent Spectrum exists to secure, and its battle-management and deconfliction problems are handled through the same networked systems that coordinate the Federation's autonomous forces in the air. The networked surface combatants and carriers of the Federal Navy provide the crewed nucleus around which the unmanned mass is organized, both as controlling units and as the high-value ships the defensive side of the doctrine is written to protect.
Limitations
The doctrine is acutely dependent on the electromagnetic spectrum. A dispersed force that cannot receive tasking or share a common picture reverts to a scattering of blind craft, and an adversary able to jam or spoof its links can defeat the mass without engaging it, a vulnerability the Federal Navy treats as inseparable from its spectrum-warfare doctrine. Endurance, sea state, and the difficulty of recovering or servicing craft far from port constrain how long a denial effect can be sustained, and the coordination of many vessels raises risks of collision and misidentification that grow with the size of the force.
The reliance on autonomous engagement sits uneasily against the constitutional constraints written into Federal doctrine after the Spring Crisis of 1739, and the more so because the naval lineage the doctrine draws on passed through the constitutionally war-renouncing Oportian Self-Defense Forces; the rules under which unmanned craft may release weapons without direct human authorization remain a subject of continuing review within the Department of Defense (Nouvelle Alexandrie). As with the doctrine's air-domain counterparts, the cost-exchange advantage it seeks is not permanent: an adversary who fields sufficiently cheap counters, or who contests the spectrum effectively, can restore the balance the doctrine exists to overturn. Critics within the Federal Navy have questioned whether a doctrine premised on expendable mass erodes the blue-water seamanship and crewed-platform investment on which the Federation would depend if it had to fight for sea control rather than merely deny it.
