When you reach Tier VII, British battleships are best used for unexpected attacks on unprepared enemies, an exchange of HP at medium ranges, and firing HE shells at long-range while restoring HP. Tiers III to VII have ships that actually served, while Monarch, Lion, and Conqueror are so-called "paper ships" - existed as blueprints, but never built. When you research all concealment-specific parameters like camo, upgrades and Commander Skills, HMS Conqueror acquires a detectability range by sea of approximately 11.0 km (12.0 km by air). The AP fuse arming delay is set at 0.15 sec, 2x less than the same shells on other battleships resulting in fewer over-penetrations when firing at poorly-armored broad targets, but be aware, this doesn’t apply to destroyers. Tier IX and X ships restore their HP much faster. Repair Party may restore more HP when compared to battleships of other nations after receiving "non-citadel" damage to the ship's bow and aft ends, superstructure, casemates, and rest of the hull.
The armor-penetrating capability of HE shells is calculated according to ¼ of a shell’s caliber, but British battleship HE damage is higher.
Their hulls are mostly smaller than hulls of other battleships, but their smaller displacements mean they also have less HP than same-tier battleships in the other nations. Good maneuverability helps, and the battleships' rudder shift times are as good as that of Germany's. Avoid concentrated fire or exposing your sides, as British battleships can’t benefit from the improved Repair Party advantages while restoring damage from citadel hits.
Tier VIII and up have more conventional bow armor protection of 32 mm (25 mm for tier VII) with the most viable tactic being an HP exchange during aggressive encounters with few enemy ships at a time. The Tier III-VI ships reward aggressive play and absorb punishment well with thick hulls and bouncy bow armor, and the tier VII-X ships gain better concealment. They also pack HE shells with increased damage and armor penetration. They're masters of mid-range marksmanship and get an improved Repair Party consumable, which restores more HP after receiving damage from shell hits. The British battleship branch makes its dramatic entrance! Say hello to these battling Britons:
