Defence Hi Freq Comms Service (DHFCS) is a military beyond line-of-sight communication system used by the British forces and other authorized users. It's is a responsibility of the Ministry of Defence (MOD) Joint Forces Command (JFC).

Its services are provided by JFC's Information Systems & Services (ISS) and the Babcock Intlernational Group http://www.babcockinternational.com/ and are based on 6 sites in the UK:
- Crimond, Inskip, Kinloss, Forest Moor, Penhale Sands and Saint Eval (all using callsign ARCHITECT)
and 4 overseas
- Cyprus callsign CYPRUS, Gibraltar callsign GIBRALTAR, Ascention Isl. callsign HAVEN and Falkland Isl callsign VIPER.

Network Control Station (NCS) is at Forest Moor controlling all DHFCS assets worldwide; The Alternate Network Control Centre (ANC) is at 2.Army-Kinloss Bcks. Both stations are manned 24/7 including RAF Flight Watch Support which is part of the DHFCS TASCOMM network with tacticall ARCHITECT.

Forest Moor netcontrol. is providing long distance strategic VLF, HF and SAT communication between British forces and UK HQs since 2008.
Former Strike Command Integrated Communications System (STCICS) has been converted into Terrestrial Air Sea Communications (TASCOMM) data service.

The Rockwell-Collins infrastructure includes new transmitters, receivers, antennas and an integrated control system giving DHFCS the following capabilities.

  1. Nuclear Firing Chain (HF/LF Secure Data)
  2. Ship to shore Automatic Link Establishment (ALE), Non ALE (Secure Data) STANAG 5066 ARQ & DRC
  3. Direct Access users Channels (Voice)
  4. Multi Channel Broadcasts (Secure Data)
  5. Single Channel Broadcasts (Data & Voice)
  6. NATO Broadcasts (Secure Data)
  7. Off the Air Monitoring (Secure Data)
  8. Legacy Ship to Shore Services (Secure Data)
  9. Rear Links Services (Secure Data)
  10. Maritime Air Telecommunication Organisation (Secure Data & Voice)
  11. Terrestrial Air Sea Communications (TASCOMM - Voice)
  12. Voice Automatic Link Establishment

The sites Anthorn and Skelton radio in northern England provides a Very Low Frequency (VLF) transmitting capability used to send communications to submerged submarines. Due to the low frequencies involved submarines can only receive VLF communications and do not carry VLF transmission aerials. Therefore, there is no requirement for land-based receiver sites as communications are one way.
