Ship Class Technical Framework
— COMMON CORE STANDARDIZATION & FLEET COHERENCE
VI.1 Purpose of the Common Core
The TriSeadon Fleet is built around a Common Core standardization doctrine that governs all non-mission-unique systems, components, and interfaces across every ship class and flight. The Common Core is the foundation that allows TriSeadon to scale, modernize, and sustain a large fleet over a 50-year service life without cost collapse, logistics fragmentation, or workforce silos.
Where SNCD governs how ships see, fight, and share the battlespace, the Common Core governs how ships are built, maintained, supplied, trained, and sustained.
The Common Core is not a design preference. It is a structural requirement.
VI.2 Scope of the Common Core
The Common Core applies fleet-wide to all systems that are not explicitly mission-differentiating. This includes, but is not limited to:
• Pumps, valves, piping, chillers, heat exchangers
• Electrical panels, cabling, breakers, connectors
• HVAC units, air handlers, filters, ducting
• Doors, hatches, ladders, rails, deck coverings, windows
• Lighting, fixtures, furnishings, lockers, berthing hardware
• Galleys, food service equipment, wardroom and mess fittings
• Tools, maintenance equipment, diagnostic gear
• Damage control equipment and fittings
• Computing hardware (screens, processors, mounts, keyboards)
• One-Consul workstations and interfaces (hardware form factor)
Every Common Core item carries one approved SKU family across the entire TriSeadon Fleet unless a documented exception is approved at the fleet level.
VI.3 What the Common Core Is Not
The Common Core does not eliminate specialization.
It does not require:
• identical weapon loadouts
• identical Integration Modules (IWMs / IMMs)
• identical mission configurations
• identical aviation or detachment assignments
Those distinctions are handled through modularity and allocation, not through divergent ship infrastructure.
The Common Core ensures that differences occur only where they create combat value.
VI.4 Common Core and Weapons / Sensors
The Common Core extends into weapons and sensors at the interface and sustainment level, not at the mission-selection level.
For example:
• All ships use the same Mk 57 PVLS perimeter VLS system
• Legacy missile compatibility is provided via a 64-cell Mk 41 VLS IWM (stop-gap, not a parallel VLS family)
• All close-in weapons mount through Cerberus universal mounts
• All guns, VLS, DEW, and future weapons must be delivered as certified IWMs that fit fleet-standard LCBs
Likewise, under SNCD:
• All ships use the same radar, sonar, EW, and combat-system families
• Mission focus is achieved by quantity and emphasis, not alternate equipment
Common Core ensures that no ship requires a unique supply chain, even when ships differ in role.
VI.5 Common Core and Modularity
The Common Core is what makes TriSeadon modularity viable at scale.
Because:
• LCB dimensions are identical across classes
• IWMs and IMMs are closed, certified systems
• ISO modules dock through standardized interfaces
• Power, cooling, data, and firefighting hookups are identical
Any approved IWM, IMM, or ISO module can be:
• installed in any compatible TriSeadon hull
• sustained using the same parts inventory
• supported by the same trained workforce
• upgraded or replaced without redesign
Modularity without a Common Core becomes fragmentation.
TriSeadon avoids this by enforcing Common Core discipline first.
VI.6 Workforce, Training, and Mobility
The Common Core enables a fleet-wide, mobile workforce.
Because ships share:
• layouts
• equipment
• consoles
• maintenance procedures
• damage control systems
Personnel can:
• cross-deck between classes with minimal retraining
• rotate between GOGO, GOCO, and COCO yards
• shift from construction to refit to sustainment roles
• surge during conflict or industrial disruption
Training pipelines are unified. Certifications are portable. Skills do not strand with a single hull type or yard.
VI.7 Lifecycle Cost Control and Inventory Reduction
Common Core standardization dramatically reduces:
• spare part proliferation
• warehouse footprint
• technical manuals
• test and certification cycles
• vendor qualification overhead
• lifecycle sustainment cost
Instead of managing three ship classes as three logistics problems, TriSeadon manages one fleet system.
This is what allows:
• continuous five-year refit cycles
• parallel construction and modernization
• predictable long-term budgeting
• sustained fleet growth without exponential cost increase
VI.8 Relationship Between Common Core, SNCD, and Modularity
TriSeadon coherence rests on three pillars, each with a distinct role:
• Common Core — controls physical standardization, SKUs, sustainment, and workforce efficiency
• SNCD — controls sensor, network, and combat-system commonality
• Modularity (LCB / IWM / IMM / ISO) — controls mission differentiation and technology insertion
None replaces the others. Each enables the others to function without failure.
VI.9 Strategic Outcome
The Common Core ensures that TriSeadon is not just a fleet of advanced ships, but a coherent naval system that can be built, sustained, modernized, and fought at scale.
It enables:
• faster production
• lower cost
• higher readiness
• workforce resilience
• long-term adaptability
Most importantly, it ensures that no future capability, ship, or mission fractures the fleet.
TriSeadon does not grow by adding exceptions.
It grows by extending a stable, disciplined core.

- FFG: 500 ft x 66 ft, about 10,000 tons, near Flight III Burke-size hull envelope, 2x25 MW continuous fully azimuthing Odyssey pods with a 27 MW short-duration objective, SPY-6(V)3F, Mk 57 PVLS (64 listed), optional later four-tube/12-round APM-IWM path, 3 LCB / 3 ISO.
- Energy acronyms: PRIME = Primary & Reserve Integrated Modular Energy; AEGIR = Adaptive Energy Grid (Integration and Redundancy architecture).
- Human-habitation technology alignment: ATLAS standardizes berthing furnishings, stowage, fittings, and installation interfaces inside fixed hull compartments; it does not modularize complete service or command rooms.
