Speed gives cruisers room to use forward firepower

The German heavy cruiser can make 23.9 knots, while the British battlecruisers reach 32 knots. That gap gives the faster ships more freedom to choose range, concentrate their guns, and keep a favourable orientation. Cruiser missions such as raider hunting, fleet scouting, trade protection, and economic warfare usually offer open-ocean room to manoeuvre, which makes forward-firing arrangements more practical. A heavily armoured battleship has less speed available and may need aft turrets because disengagement is harder. The contrast ties turret layout to mission and expected freedom of movement.
