S-1 — U.S.S.R. Tech Tree Tier VI Submarine.

The Soviet Navy's first truly ocean-going submarines were based on a German design developed by a front company in the Netherlands for Spain. For their size, the boats had quite powerful armament, including four bow and two stern torpedo tubes. A trial series of three units (IX series) was commissioned from 1936 through 1938. One of the submarines was sunk during the Winter War; the rest, including S-1, were lost in the first days after Germany invaded the U.S.S.R. in June 1941.

Pros

• High speed on the surface
• Alternative torpedoes do heavy damage
• Long range submarine surveillance

Cons

• Homing torpedoes have limited range and damage
• Low speed while submerged
• Poor maneuverability

Ship Change Log

• Update 14.0:
  • Sonar parameters changed:
  • Stock sonar module:
    • Reload time increased: 8 to 17.5s
    • Ping velocity increased: 500 to 800m/s
  • Researchable sonar module:
    • Reload time increased: 6.5 to 15s
    • Ping velocity increased: 500 to 800m/s
  • Torpedo parameters changed:
  • Stock Acoustic torpedoes:
    • Arming distance increased: 300 to 400m
    • Speed reduced: 75 to 66 knots
  • Researchable Acoustic torpedoes:
    • Arming distance increased: 300 to 400m
    • Speed reduced: 75 to 66 knots
    • Detectability range reduced: 2.0km to 1,7km
    • Stock Alternative torpedoes
    • Arming distance increased: 300 to 400m
    • Damage increased: 10,567 to 12,133
    • Speed increased: 65 to 69 knots
    • Researchable Alternative torpedoes
    • Arming distance increased: 300 to 400m
    • Damage increased: 11,833 to 13,600
    • Speed increased: 65 to 69 knots
    • Note that all submarine torpedoes deal reduced damage within the first few kilometers traveled. For the first 2.9km, they will only deal 10% damage, while from 2.9km to 3km, their damage will scale up to 100% linearly, avoiding scenarios where a single-meter difference could result in drastically different damage.
    • Dive Capacity reduced: 210 to 180 units
    • Dive Capacity recharge rate increased: 0.8 to 1.5 units/s
    • Maximum Dive and Ascent speed reduced
    • Acceleration parameters improved. The ship now reaches full engine power sooner, with settings similar to destroyers
    • Surface detectability range increased: 6 to 6.1km
    • All other detectability ranges adjusted accordingly
  • Submarine surveillance consumable parameters changed:
    • Action time increased: 20 to 40s
    • Cooldown time increased: 80 to 110s
    • Preparation time increased: 290 to 310s
    • Submarine detection range increased: 7 to 9km
  • Damage Control Party consumable changed to Fast Damage Control Team with the following parameters:
    • Action time: 5s
    • Cooldown time: 45s
    • Number of charges: 4
