Merchant ships could stock secret bases without a special plan

Was there a special plan to requisition British merchant ships to stock the secret Indian Ocean bases?

No special plan was needed; taking up merchant ships for naval support was already an understood British practice.

No distinct secret plan was needed to requisition British merchant ships in the Indian Ocean for secret-base supply because taking up merchant shipping was already an understood option when required. Britain's large merchant fleet gave planners a pool of hulls that could move stores without every use being written as a separate doctrine. Ordinary mobilization powers could support a concealed basing system while the locations and timings remained secret.
