Abilities

• Covert: invisible to enemies unless a sea detector (Destroyer, AWACS, Strategic Radar) reveals it. Fighting reveals it temporarily.
• Hard-counters warships.
• Hunted by destroyers, which counter it.

Counters

• Hard-counters: Warship
• Countered by: Destroyer

Hard-countered units take extra losses and cannot retaliate against the unit countering them. See Units#Counters for the full matrix.

Production

Trained at the Naval Base. Build time, cost and upkeep depend on the tier (see Stats).

In combat Submarine expends Torpedoes. Ammunition is crafted in batches at ammunition buildings (Ammunition Factory, Ordnance Plant); keep the army supplied to stay effective in prolonged fighting.

Movement and transport

As a naval unit it operates on sea nodes and cannot enter land districts.

Stealth and detection

Submarine is a covert sea unit: an army made only of covert units is invisible to enemies unless a sea detector reveals it. Fighting (or firing) reveals it temporarily.

Sea detectors: Destroyer, AWACS, Strategic Radar.

Detection is rolled once per detector scan, every 10 minutes; a successful roll reveals the army for 30 minutes. Fighting always reveals it. The research focus Detection Radius widens detection ranges. See Stealth and Detection.

Tips

• Invisible until a sea detector (Destroyer, AWACS, Strategic Radar) rolls a successful reveal. Fighting reveals it temporarily.
• Hard-counters warships; avoid destroyers, which both detect and counter it.
