HMS Seal: Tier X British Submarine

A large mine-laying submarine which was commissioned to the Royal Navy in 1939. In the Second World War, HMS Seal operated in several theatres from Aden to Halifax. During her combat mission in the Kattegat Strait in May 1940, the heavily damaged submarine was forced to surrender by German aircraft.

Key Features

• Torpedo Characteristics: The torpedoes have a long range and fast ping speed, making it easier to strike from afar, but their homing cuts off at distances that can give targets more time to evade. The range cutoff varies by target type:
  • Battleships: 3 km
  • Aircraft Carriers: 1.7 km
  • Cruisers: 2 km
  • Destroyers: 680 m
  • Submarines: 240 m
• Reload Time: The torpedoes' reload time is long, requiring patience between shots.
• Survivability: Seal has a large hitpoint pool, which allows it to endure damage when surfaced. It also has a high dive capacity, though it regenerates slowly, giving it a blend of endurance and vulnerability.

Gameplay Advice

Tactical Playstyle: Seal operates as a hybrid, effectively blending submarine stealth with the offensive potential of a torpedo destroyer. Focus on:

• Targeting Poorly Positioned or Slow-Maneuvering Ships: Ideal targets include enemy battleships and cruisers near islands or in open water with limited maneuverability.
• Avoiding Submarine Engagements: Seal’s limited torpedo versatility and homing cutoff against submarines make direct confrontations with other subs dangerous.

The key is to take advantage of Seal’s powerful long-range attacks while managing its reload times and avoiding scenarios where it might be forced into close-range battles or against fast-moving submarines.
