How radio silence protected the strike

Did Fleet Air Arm aircraft use VHF radio during the Taranto strike?

Some aircraft had radios, but the strike appears to have maintained radio silence unless recovery became impossible by other means.

Radio fit varied across Fleet Air Arm aircraft at the time, and the Taranto force appears to have used little or no radio communication during the attack. British doctrine preferred silence unless a lost aircraft could not recover by other means. Avoiding transmissions reduced the chance of warning defenders or revealing the carrier. It also demanded exceptional navigation and disciplined execution.
