HMS Forth, first of five new Offshore Patrol Vessels has been formally named in Glasgow today.

HMS Forth was named by the Lady Sponsor Rachel Johnstone-Burt who broke a bottle of whisky on the bow.

The OPV will soon depart on sea trials before entering service with the Royal Navy in 2018. She is the first of a fleet of five new Batch 2 River-class OPVs being built on the Clyde which are all expected to be in service by 2021.

The vessels were earlier described at a Defence Select Committee meeting as ships “the Royal Navy does not want or need”. It is understood that the Ministry of Defence paid an extra £100 million for new Offshore Patrol vessels in order to satisfy a requirement to pay BAE a minimum of £230 million per year and despite this, the vessels will be much less capable than vessels of similar price.

A house of Commons Briefing Paper explains the agreement:

“In 2009 the Government signed a 15 year Terms of Business Agreement (TOBA) with BAE Systems and Babcock. The TOBA guaranteed BAE Systems a minimum level of surface ship build and support activity of £230 million a year.

This was judged as the minimum level of work possible to sustain a credible warship-building industry in the UK and thus avoid the delays encountered during the Astute class submarine build caused in part by the loss of skilled staff following the gap between Astute and the Vanguard class submarine build.

If cancelled the MoD would be liable for industry closure costs and compensation to BAE Systems.”

The government say that the work to build HMS Forth and her sister ships is sustaining around 800 Scottish jobs.

Minister for Defence Procurement, Harriett Baldwin, said:

“As part of a sustained programme delivering world-class ships and submarines, HMS Forth’s naming is a vitally important part of the Government’s ten-year £178 billion plan to provide our Armed Forces with the equipment they need.

From counter-narcotics operations in the Caribbean, to securing the UK’s borders on patrols closer to home, the Royal Navy’s new Offshore Patrol Vessels will help protect our interests around the world.”

First Sea Lord and Chief of Naval Staff, Admiral Sir Philip Jones, said:

“With the naming of HMS Forth, the Royal Navy looks forward to another impending arrival in our future Fleet. In a few short years, these five Offshore Patrol Vessels will be busy protecting the security of UK waters and those of our overseas territories.

They are arriving in service alongside a new generation of attack submarines and Fleet tankers, and will be followed shortly by new frigates and other auxiliaries; all of this capability will coalesce around the Queen Elizabeth-class carriers.

Together, they form a truly balanced Fleet, able to provide security at sea, promote international partnership, deter aggression and, when required, fight and win.”

The Offshore Patrol Vessels were ordered to fill a gap in orders after the second carrier and before the Type 26 frigates begin construction.

Regarding the cost of the new Offshore Patrol vessels:

“The provisional cost of the new vessels was given as £348 million but because the TOBA required a £230 million a year spend with BAE, the Defence Secretary estimated the additional cost to the MoD of the ships, over and above the payments the MoD would have had to have made to BAE, is less than £100 million.”
