— TRISEADON SHIP CLASSES
III.1 Purpose of the Three-Class Structure
The TriSeadon Fleet is built around three purpose-designed surface combatant classes, each optimized for a primary warfare domain while remaining fully interoperable within a unified fleet architecture.
This three-class structure deliberately avoids the historical extremes of:
• Overloading a single ship type with every mission, or
• Fragmenting the fleet into incompatible specialty platforms
Instead, TriSeadon assigns clear primary roles, supported by shared systems, common interfaces, and fleet-level integration that allows every ship to contribute meaningfully beyond its specialization.
The result is a fleet in which:
• Each ship is excellent at its primary mission
• No ship is ever tactically isolated
• Capability increases exponentially as ships operate together
III.2 Guided Missile Frigate (FFG) — Undersea Dominance Platform
The FFG is the most numerous combatant, sized in a near Flight III Burke envelope (about 500 ft x 66 ft) with frigate mission configuration.
Primary Role
• Anti-Submarine Warfare (ASW)
• Escort of high-value units
• Persistent maritime presence
Fleet Function
The FFG establishes undersea control, forming the backbone of fleet survivability in both peace and conflict. Its design prioritizes:
• Acoustic quieting
• Long-duration operations
• High availability and affordability
By assigning routine escort and undersea dominance to the FFG, TriSeadon:
• Relieves destroyers and cruisers of escort saturation
• Enables high-end combatants to focus on contested missions
• Restores a capability gap left by the retirement of legacy frigates
Force-Multiplication Role
While optimized for ASW, the FFG contributes to:
• Distributed sensing
• Unmanned system operations
• Networked engagement support
When operating with DDGs and CAGs, the FFG acts as the primary undersea hunter, with other ships expanding the detection and engagement envelope.
III.3 Guided Missile Destroyer (DDG) — Air and Missile Defense Platform
The DDG serves as the fleet’s primary air and missile defense combatant, enabling forward operations in contested environments. Its updated hull scale is about 650 ft x 88 ft, intentionally larger than Zumwalt.
Primary Role
• Integrated Air and Missile Defense (IAMD)
• Fleet and task group protection
• Theater-level defensive operations
Fleet Function
The DDG provides the protective umbrella that allows FFGs, CAGs, carriers, and amphibious forces to operate forward. Its design emphasizes:
• Sensor coverage
• Engagement coordination
• Magazine depth distribution
The DDG is not intended to replace all existing destroyers immediately. Instead, it:
• Replaces aging destroyers as they retire
• Expands fleet capacity as numbers grow toward the 355-ship objective
• Preserves effective legacy ships until replacement is operationally justified
Force-Multiplication Role
Beyond air defense, the DDG:
• Contributes to undersea warfare through sensors, aviation, and unmanned assets
• Extends surface and strike engagement geometry
• Acts as a distributed combat node rather than a single point of failure
III.4 Guided Missile Heavy Cruiser (CAG) — Surface Warfare and Command Platform
The CAG is a true heavy guided missile cruiser, designed to restore and expand fleet-level capabilities lost with the retirement of legacy cruisers. Its updated hull scale is about 800 ft x 108 ft, in the battlecruiser/pocket-battleship size class.
Primary Role
• Surface warfare dominance
• Mobile Quick Reaction Force (QRF)/ light amphibius assault
• Fleet command and control
Fleet Function
The CAG serves as:
• A command node for distributed surface operations
• A surface and strike warfare anchor
• A provider of missile magazine depth and operational endurance
Unlike legacy cruisers, the CAG is designed from inception to:
• Operate with unmanned systems
• Support expeditionary and crisis-response missions
• Integrate command, strike, and sustainment functions organically
Force-Multiplication Role
When deployed with FFGs and DDGs, the CAG:
• Coordinates fleet-wide operations
• Concentrates combat power without centralizing risk
• Enables rapid escalation or de-escalation across multiple domains
III.5 Inter-Class Synergy and Complementarity
TriSeadon’s power does not come from any single ship—it comes from how the classes work together.
• FFGs dominate the undersea domain
• DDGs secure the air and missile domain
• CAGs lead surface warfare and command
Each class:
• Reinforces the others’ strengths
• Expands sensor and engagement coverage
• Shares common systems, interfaces, and logistics
This structure ensures that:
• No class must be overbuilt to compensate for another
• Capability scales naturally with fleet size
• Loss or unavailability of a single ship does not collapse combat effectiveness
III.6 Scalability and Longevity
All three TriSeadon ship classes are designed for:
• Long service life
• Continuous modernization
• Role flexibility within defined boundaries
As technology evolves, mission emphasis may shift, but the three-class structure remains stable, allowing the fleet to adapt without re-architecting its foundation.
III.7 Section Outcome
Section III establishes that TriSeadon is not a collection of ships, but a deliberately balanced combat system, where:
• Each class has a clear purpose
• No capability is isolated
• Fleet power grows with every hull added
The following sections detail how this structure is enabled technically and industrially, without compromising schedule, cost, or readiness.
