S-61N Mk2 operated on behalf of HMCG by Bristow Helicopters in Scotland and on the south coast of England.
Bristow had previously had SAR experience with the S-61N when it started a private SAR service around the North Sea hydrocarbon fields in Feb 1978 for BP. Its first involvement with HM Coastguard was when it took over contract SAR cover for the Shetland Islands based at Sumburgh (EGPB) in Dec 1983, from British Airways Helicopters. These two airframes operate as Rescue 117 and Rescue 118.
SAR operations expanded with Bristow in May 1987, when the Hebrides contract was let. Up to two airframes (one is on standby) are based at Stornoway (EGPO) and operate as Rescue 119 and Rescue 120.
Bristow's third S-61N contract with HMCG was taken on in Jun 1988 from a 202 Squadron Sea King HAR.3 detatchment at Lee-on-Solent (EGUS). When on SAROPS it uses callsigns in the range Rescue 174 to Rescue 176.
When the Royal Navy's plans to withdraw from RNAS Portland (EGDP) emerged, it would leave a gap in SAR coverage. Bristow's fourth SAR contract was for a single helicopter to be based at Portland. On operations, it is Rescue 172 or Rescue 173.
