The U. S. Navy Transportable Communication System AN/TSC-35 is a complete communication station consisting of a Receiving Central AN/TSR-1 (COMMCENTER/Receiver site) and a Transmitting Central AN/TST-2 (Transmitter site). (See artists concept of completed sites, figures 1-1 and 1-2.) Communication equipment, repair, supply, and primary power facilities at both sites are housed in 40-foot containers which have been designed for land or sea transport and for rapid on-site installation. Associated transmitting and receiving antennas, primarily in kit form, can likewise be installed in a minimum of time. The assembled communication system provides point-to-point, ship-shore, air-ground and broadcast communication facilities, with cryptographic capability, of the extent and quality comparable to a fixed shore communication station.
Communication System AN/TSC-35 is comprised of 26 containers at the Receiving Central AN/TSR-1 arranged as shown in figure 1-3, 30 containers (and a Helix container which is not shown) at the Transmitting Central AN/TST-2 arranged as shown in figure 1-4, and one mobile workshop trailer. The containers at each site (except for the power group, the mobile workshop trailer and Helix container) are joined together end-to-end to form wings, and the wings are joined allowing internal access from wing to wing. The containers are mounted on adjustable support assemblies that allow for all joined containers to be maintained at the same level. The containers are identified according to their positions in their respective wings at each site, such as RA1 or TA1, the R for receiver site or T for transmitter site, the A for the wing location, and the 1 for the first container in the wing nearest the center of the group. The forward ends of the containers face the outside of the complex. The power generation and distribution containers at both sites are physically separated from the remainder of the complex as illustrated in figure 1-3 and 1-4. These containers are designated by first a letter G, followed by R for Receiving Central or T for Transmitting Central, and a numeral suffix such as 1 for Power Distribution, 2 for Power Control, and 3, 4, 5, or 6 for Generators. All AN/TSC-35 containers, with the exception of the power distribution, generator and helix containers, are equipped with all-weather air-conditioning units that mount on the outside walls.
