The wider theatre contained more Royal Navy capital ships than the Force Z label suggests, but availability and timing mattered. HMS Royal Sovereign and HMS Revenge were already in the Indian Ocean, yet they were older ships rather than a modern concentrated striking force at Singapore. HMS Indomitable was expected in January, while HMS Ramillies would arrive in late January or early February, after the decisive December sortie. Counting fleet inventory across the theatre overstated the force Phillips could use during the December crisis.

Reinforcements existed, but not for the December crisis
Older battleships were elsewhere in the Indian Ocean, while HMS Indomitable and further capital-ship strength would not arrive until January or February.
