Key Features and Battle Tips

Key Features

• Devastating 16-Gun Broadside: Armed with 16 × 356 mm guns mounted across four quadruple turrets.
• High Rate of Fire: Base reload time of 25 seconds delivers exceptional sustained DPM.
• Formidable British HE: High explosive shells boast 89 mm armor penetration, 5,500 maximum damage, and a 28% fire chance.
• Strong Concealment & Speed: Top speed of 31.5 knots paired with a low surface detection radius (down to ~12.1 km when fully specialized).
• Solid AA Suite: Robust mid- and long-range anti-aircraft protection to deter enemy airstrikes.
• Fragile Citadel & Armor: A massive, exposed citadel combined with 32 mm external plating makes her vulnerable to heavy AP broadsides and focus fire.

Battle Tips

• Prioritize HE Salvos: Rely primarily on HE against angled targets, heavily armored battleships, and destroyers. The sheer volume of 16 shells with 89 mm penetration strips chunks of HP and causes constant fires.
• Punish Broadside Cruisers with AP: While 356 mm AP struggles against angled capital ships, it is devastating against broadside cruisers and lighter battleships within medium ranges.
• Never Show Pure Broadside: Bringing all 16 guns to bear requires showing a wide angle. Only unmask the rear turrets between enemy reload cycles or when unspotted.
• Leverage Concealment: Use your low surface detection to reposition, disengage from unfavorable engagements, and surprise broadside targets.
• Play from Mid-to-Long Range: Maintain engagement distances between 13 km and 18 km. Rushing into close-quarters brawls will quickly result in catastrophic citadel damage.
