HM Coastguard: Radio Network Infrastructure Replacement Programme

HM Coastguard is replacing the radio network, that connects 165 remote sites, to aid search and rescue operations around the UK.


The current radio network is run on copper telephone wiring. The network is out of date and is no longer viable, so is being decommissioned.

The Radio Network Infrastructure Replacement Programme (RNIR) began summer 2020 and is expected to take a minimum of three years to complete.

The new network

The new radio network is being built by the Maritime and Coastguard Agency, who oversee HM Coastguard.

It will largely run on modern fibre cables which is being installed by Telent Technology Services Ltd. Where it is not possible to install new cables then line-of-sight microwave links will be used.

The new hybrid network will be more secure and reliable, it will also include new connection points to ensure full diversity and resilience which will play a central part in preventing loss of life on the coast and at sea.

With new fibre cables being laid around remote areas of the UK, it could enable those close by to access superfast broadband services from their supplier.


The new fibre-based hybrid radio network will make sure HM Coastguard can continue to:

  • communicate with ships, smaller craft, and other leisure users in UK waters to advise on navigation hazards or receive distress alerts
  • track shipping and other craft through automatic identification systems
  • communicate and co-ordinate search and rescue assets including HM Coastguard Rescue Teams, lifeboats, HM Coastguard helicopters, fixed wing aircraft and the emergency tug, which all save lives and protect the marine environment
  • launch and coordinate hundreds of charitably funded lifeboats that save lives
