Government response
There are currently no plans to close HMS GANNET at Prestwick or move the facility to Glasgow.
As part of the joint MOD and Maritime and Coastguard Agency (MCA) PFI project (SAR-H) to provide a future Helicopter Search and Rescue capability, it was announced in February 2010 that the preferred bidder was Soteria, who have chosen to relocate the future service to Glasgow Airport.
On 17 June the Chief Secretary to the Treasury announced that the Government intends to undertake a rapid review of the SAR-H project in the context of the wider pressures on public spending. Until this review has been completed it would be premature to comment on basing of the future SAR-H service.
HMS GANNET, as a Royal Naval Air Station, has a wider military role and its future is not directly related to the SAR-H decision. MOD has a long-term commercial lease with the Prestwick Authorities for this Air Station. All aspects of Defence will however be under scrutiny as part of the on-going Strategic Defence and Security Review."
