There exist various methods which have been proposed to satisfy the Navy's need to communicate with its submarines while they are underwater. Among these are the ELF system, whose major drawback is that it cannot be implemented as a hardened system without the possibility of major environmental impact; a system involving the use of laser in the blue-green range mounted on a satellite; and the method to be discussed in this paper - the VLF TACACMO survivable system. TACAMO - an acronym for 'take charge and move out' - consists of a squadron of C-130's and associated communications equipment. One aircraft can be airborne at all times, ready to relay the emergency action message (EAM) to the submarine fleet. The Tacamo aircraft is a communications center whose function is to receive the EAM via UHF, HF , or VLF from a ground, airborne, or satellite source and retransmit it via VLF to the submarine fleet. Transmission of the EAM requires an accurate time and frequency reference. This requirement has been met by Frequency and Time Systems (FTS) through its development of a time and frequency reference system for the Tacamo program.
