Aegiran Navy (Stolos)¶
The Aegiran Navy — the Stolos — is the republic's senior service and the principal combat arm of the Aegiran Federal Defense Forces. Approximately 110,000 active personnel including the Naval Air Arm, the supporting shore establishment, and the substantial Naval Reserve cadre.
The Stolos is the largest blue-water peer navy in central Sierra and the principal WDP naval force in the Aegiran Sea theater. Its modern lineage traces directly from the pre-classical Aegiran maritime tradition; the institutional continuity of the service extends across 1,600 years of recorded history, with no significant interruption.
Doctrine¶
The Stolos is a blue-water sea-control navy built around three core missions:
- Aegiran Sea sea control — denying hostile naval forces operational freedom; protecting Aegiran and WDP shipping; constraining CSAT resupply of the occupied eastern islands
- Power projection from the sea — providing amphibious lift, naval gunfire, and air support for Marine and coalition land operations, particularly the planned eastern islands recapture
- Coalition operations — integrating with WDP and MTF partners across the broader Sierran maritime theater
The Stolos is doctrinally focused on surface combatants and attack submarines at the high end, with substantial amphibious lift and supporting elements. The republic does not operate fleet aircraft carriers; coalition fleet aviation is provided by FSA carriers in WDP framework operations. The Stolos operates no nuclear-powered combatants — the submarine arm is entirely conventional diesel-electric (AIP) — and fields no SSBNs, per Sierran Conflict canon (nuclear technology is restricted to power generation; WMDs are space-based kinetic systems banned under the Outer Space Demilitarization Protocols).
Force structure¶
The Stolos is organized by mission rather than by region, under a single national fleet:
- Surface Force — destroyers, frigates, corvettes, and fast-attack craft; the principal combat formation. Headquartered at Krygos
- Submarine Force — six conventional AIP-equipped attack submarines (SSK) operated across the federal naval bases
- Amphibious Force — landing ships, beach-assault capabilities, and the embarked Marine support shipping
- Naval Air Arm — maritime patrol, anti-submarine warfare, fleet helicopters, and a small land-based fixed-wing capability
- Coastal Defense Command — integrated coastal artillery, harbor defense, mine warfare, and the republic's substantial naval mine capability
- The Naval Shore Establishment — bases, shipyards, training, supply, and administrative functions
For operational purposes the surface force is divided into the Aegiran Fleet (principal combat force, Krygos) and the Pharosian Squadron (western fleet element, Pharos, responsible for the western Aegiran Sea and southern oil-shipping routes).
Principal vessels¶
Surface combatants¶
| Class | Type | Role | Quantity |
|---|---|---|---|
| Hydra-class equivalent (designation TBD) | Destroyer (DDG) | Anti-air, anti-surface, ASW | 4-6 |
| Krygos / Elli-class equivalent (designation TBD) | Frigate (FFG) | Anti-submarine, general purpose | 8-10 |
| Corvette (class TBD) | Corvette | Coastal patrol, near-water defense | TBD |
| Patrol vessel (class TBD) | OPV | Archipelago patrol, coast-guard role | substantial |
| Fast-attack craft (class TBD) | Missile FAC | Inter-island patrol, anti-surface | TBD |
Class designations are pending — Krygos Naval Shipyards builds under licensed-foreign design as well as domestic design, and the formal class names will be set as the OOB build progresses.
Submarines¶
| Class | Type | Role | Quantity |
|---|---|---|---|
| AIP attack submarine (class TBD) | SSK (diesel-electric, AIP) | Sea-lane interdiction, ISR, anti-shipping | ~6 |
The Stolos does not operate nuclear-powered submarines and fields no SSBNs. Likely class: Gotland-class equivalent (Gorlund export) or Type 214 equivalent (Leipzisch export), built at Krygos Naval Shipyards under licensed-foreign design.
Amphibious¶
| Class | Type | Role | Quantity |
|---|---|---|---|
| LHD (class TBD) | Landing Helicopter Dock | Marine assault, helicopter ops | 1-2 |
| LPD (class TBD) | Landing Platform Dock | Marine landing, well-deck ops | 2-3 |
| LST (class TBD) | Landing Ship Tank | Vehicle landing, beach assault | substantial |
| LCAC / LCU (class TBD) | Landing craft | Ship-to-shore connectors | numerous |
The Stolos amphibious capability is proportionally larger than typical peer navies of comparable total size, reflecting the strategic centrality of the eastern islands recapture mission. The amphibious group is the only blue-water amphibious-assault force in southern Sierra.
Mine warfare and auxiliaries¶
The Stolos maintains a substantial mine countermeasures fleet given the archipelago's narrow approaches, plus the standard peer-tier auxiliary inventory: fleet oilers, replenishment ships, hospital ships, salvage and recovery vessels. Quantities and class specifications TBD pending the OOB build.
Bases¶
| Base | Island | Role |
|---|---|---|
| Krygos Naval Base | Krygos | Principal fleet headquarters; the largest naval base in central Sierra |
| Heliopolis Naval Base | Heliopolis | Secondary fleet base; Naval Air Arm primary station; major shipyard |
| Pharos Naval Base | Pharos | Pharosian Squadron homeport; western maritime operations |
| Karthago Naval Station | Karthago | Coastal patrol; submarine support; agricultural-island logistics support |
| Federal Naval Academy | Krygos | Officer training; staff college; by tradition the senior officer-training institution of the AFDF |
The pre-war base at Mytilene is currently under CSAT occupation; its facilities have been seized intact and are reportedly in CSAT operational use.
Naval Air Arm¶
The Naval Air Arm operates:
- Maritime patrol aircraft — long-range surveillance, anti-submarine warfare (P-8 Poseidon)
- Anti-submarine helicopters — NH90 NFH embarked on destroyers and frigates
- Naval strike aircraft (land-based) — limited fixed-wing combat capability, principally ship-defense and maritime strike, overlapping with the Air Wing's Maritime Strike Wing
- Search-and-rescue rotary-wing — AS532 Cougar distributed across coastal stations
The Naval Air Arm is small but capable. It does not include carrier-based aviation in the FSA Navy sense — the Stolos has no carriers.
Coastal Defense Command¶
A significant proportion of Stolos personnel and equipment is in Coastal Defense Command, the integrated coastal artillery and harbor defense organization. CDC operates:
- Coastal anti-ship missile batteries — truck-mounted RBS-15 KA equivalent (Bofors-Gorlish export) or Naval Strike Missile equivalent, covering the major harbor approaches and the inter-island sea lanes
- Coastal artillery — heavy gun and missile artillery on each federal island, integrated with the Army Coastal Defense Battalions
- Naval mine warfare — substantial defensive mine inventory and the dedicated minelaying capability to deploy it on warning
- Harbor defense — fixed harbor surveillance, anti-swimmer measures, port security
- The Coastal Surveillance Network — radar and electro-optical surveillance covering the approaches to every federal-controlled harbor
The CDC's capabilities are a deterrent to a CSAT-style amphibious assault on the remaining four federal islands; the 2026 fall of the eastern islands has substantially increased CDC investment and operational tempo.
OFBN-WDP Joint Maritime Command¶
The WDP Joint Maritime Command (JMC) at Krygos coordinates allied naval operations across the central Sierran theater. JMC is staffed by personnel from all WDP navies, with the senior Aegiran admiral as the standing chair (a position reflecting the Stolos's senior role in the theater).
JMC functions:
- Coalition operational planning for the Aegiran Sea and adjacent waters
- Coordinated maritime patrol — integrated WDP naval coverage of the theater
- Intelligence sharing — particularly on CSAT and DPRR naval movements
- Logistics coordination — sharing of basing rights, supply chains, repair facilities
Special operations¶
The Aegiran Naval Frogman Detachment is the Navy's SOF element: combat divers, ship-boarding, maritime counter-terrorism. Based at NAB Krygos, the Frogman Detachment reports to the AFDF Special Forces Command and works closely with the Marine Reconnaissance Battalion on amphibious special operations.
Current operations (Continuation War)¶
The Stolos is in full wartime posture. Principal current operations:
- Aegiran Sea sea control patrols (continuous)
- Anti-submarine operations against CSAT and DPRR-aligned submarine activity
- Surface combatant operations to interdict CSAT supply to the occupied eastern islands
- Coalition convoy escort for WDP and MTF shipping through the southern oil routes
- Amphibious group exercises in preparation for the planned eastern islands recapture
- Coastal defense of the four federal islands' approaches
The naval war has been steadily favorable for the Stolos and WDP since the initial August 2026 setback. CSAT naval forces have been progressively constrained to a defensive posture around the occupied eastern islands; CSAT amphibious offensive capability has been substantially attrited. The eastern islands recapture is not yet ready operationally, but the precursor naval campaign is being won.
Notes on the loss of the eastern islands¶
The Aegiran Navy was not the primary failure point in the 2026 loss of the eastern islands. The CSAT operation succeeded through a combination of operational surprise, mass amphibious tonnage, and the Aegiran Navy's commitment to defending against an expected attack vector that proved not to be where the CSAT struck. Subsequent analysis identifies failures of intelligence and operational deployment rather than failures of fleet capability.
The Stolos's institutional response has been characteristically professional and unsentimental: lessons identified, corrective action taken, doctrine and posture updated. The senior Stolos leadership has not been politically scapegoated; the conduct of the early August 2026 naval operations is broadly considered to have been as good as could have been managed given the intelligence picture and force disposition. The recapture campaign will provide the test of whether the Stolos has learned the right lessons.
