Frigate
[SYSTEM_DOSSIER // NAV-03] // FLEET AIR DEFENSE / ESCORT WARSHIP
Frigate
The Frigate is the Naval Fleet’s dedicated air-defense escort. Its value comes from the combination of anti-air damage, long engagement range, radar coverage and survivability — not from one damage number alone. It remains a genuine multi-target warship, contributing against surface vessels, submarines, helicopters, missiles and other units while higher levels improve drone coverage and stealth detection.

Frigate Combat Identity
Aircraft ATK
6 → 10
The defining damage track. Frigates scale into powerful fleet air-defense escorts.
Aircraft / Drone Range
75 → 100
The major early breakpoint arrives at Level 2: engagement range increases by 25.
Radar Range
75 → 100
Radar improves alongside the early air-defense range upgrade.
Hit Points
28 → 38
Survivability steadily rises so the escort can remain alive inside valuable fleet stacks.

● AIR DEFENSE FIRST / MULTI-TARGET SECOND
Aircraft & Drones
The Frigate’s defining job is protecting the fleet from airborne threats. Damage, attack range and radar must always be evaluated together.
Surface & Submarine Combat
Do not discard the remaining combat vector. Frigates continue to add damage and defense against ships, submarines, helicopters, missiles and supporting target classes.
Detection
Higher levels gain stronger detection utility, including the later ability to reveal stealth airborne units. This makes advanced Frigates both weapon platform and fleet sensor.

Why Level 2 Matters So Much
The raw aircraft damage only rises from 6 to 6.5, but the aircraft/drone engagement range and radar both jump from 75 to 100. That changes the geometry of fleet defense: the Frigate can cover a much larger area around carriers, cruisers and other valuable ships before an incoming air unit reaches the stack.

// Detection Rule //
● RANGE + RADAR + STEALTH MUST STAY SEPARATE
Attack Range
Controls how far the Frigate can engage a particular target class. Aircraft/drone coverage reaches 100 early.
Radar
Radar is its own detection field. It rises from 75 to 100 and should not be treated as the same value as attack range.
Stealth Detection
A later property allows the Frigate to reveal stealth airborne units. Keep this as a boolean/range-based detection capability rather than extra damage.

Upgrade Breakpoints
L1 → L2 // Range Is The Upgrade
Aircraft damage only gains 0.5, but engagement range and radar both jump 75 → 100. This is the most important early Frigate breakpoint.
L3–4 // Stronger Multi-Target Escort
Air damage rises to 7 then 8, while surface, submarine and missile-target combat also improves. The Frigate increasingly contributes even when the enemy is not attacking from the air.
L5 // Mobility
Movement rises to 4 / 2 while HP reaches 35. The escort can better stay attached to higher-end surface fleets.
L6–7 // Late Detection
Aircraft ATK reaches 9 then 10, HP reaches 36 then 38, and the late progression includes stealth-air detection. This is where the Frigate becomes a full late-game defensive sensor platform.
// Final Player Verdict //
● THE FLEET’S AIR-DEFENSE UMBRELLA
Use It For
Protecting carriers, cruisers and mixed surface stacks from aircraft, helicopters and drones while still contributing useful damage against ships and submarines.
Do Not Compare By Damage Alone
The combination of attack range, radar, HP and stealth detection often matters more than a small increase in raw AA damage.
Best Breakpoints
L2 for the 100-range air-defense screen. L5 for mobility. L6–7 for maximum AA, survivability and late-game detection utility.
