Modern Russian weapons outweigh the Home Fleet only if they work

Who would win between the Second World War Home Fleet and the modern Russian Navy?

The modern Russian force should win through missiles, sensors, and submarines, provided its ships, weapons, crews, and support systems are actually operational.

The technological gap gives a modern navy enormous advantages in detection, range, guidance, and underwater attack. Russian submarines and long-range weapons should therefore damage the wartime Home Fleet before its guns can matter. That outcome assumes the modern systems are maintained, supplied, crewed, and functioning. A paper comparison of generations can conceal the operational-readiness failures that decide whether advanced weapons can be used at all.
