Naval Base

[BUILDING_DOSSIER // C03] // MARITIME FORCE PROJECTION NETWORK

Naval Base

Single-tier crossing infrastructure designed to open aquatic transit routes for ground forces. Naval Base reduce embarkation and airlift duration by 5%, require at least 40% structural health to function, and are limited to one structure per province coordinate.

Tactical Blueprint

The Naval Base controls maritime production and coastal deployment. The supplied dossier distinguishes the free Level 1 homeland Harbor baseline from the military Naval Base upgrades that follow, with higher infrastructure unlocking progressively heavier naval assets.

Embarkation logistics: the listed embarkation modifier improves from -5% time at the free Harbor baseline to -50% time at the highest listed infrastructure tier.

[PREREQUISITES_MATRIX]

Requirements Matrix

  • Friendly homeland coastal cities receive the Level 1 Harbor baseline for free.
  • The baseline Harbor can produce Patrol Boats when paired with Arms Industry Level 1.
  • Subsequent infrastructure tiers are active military construction upgrades.
  • The source states that Naval Base operations require at least 40% HP to remain operational.

Strategic Intelligence // Maritime Doctrine

Free Coastal Baseline

The source treats the Level 1 Harbor as a free homeland standard rather than a normal paid Naval Base upgrade, giving coastal homeland cities an immediate maritime starting point.

Projection Scaling

Higher tiers simultaneously improve embarkation time, local resource output and access to heavier naval hulls, making advanced ports strategic production and logistics hubs.

40% HP Threshold

The supplied warning states that Naval Bases must remain at or above 40% HP; below that threshold, ongoing ship construction freezes and capital hulls cannot be mobilized until the shipyard is repaired.

Harbor-To-Fleet Progression

The supplied progression begins with a free 5 HP homeland Harbor and scales to a 25 HP advanced naval facility with -50% embarkation time and +20% local resource output, while progressively unlocking heavier naval assets.
