What a modernized HMS Tiger might carry

What would a modernized HMS Tiger look like?

Likely 14-inch main guns, improved engines and armor, and 4.5-inch dual-purpose secondary mounts.

The 13.5-inch battery is replaceable rather than fixed. Twin 14-inch guns offer the most plausible main-armament upgrade. Better engines and some additional armor would address the ship's age and improve operational usefulness. The secondary battery would move to dual-purpose weapons, probably 4.5-inch mounts, so the reconstruction also improved anti-aircraft defense.
