Replacing the Trident nuclear missile submarines will not create any new jobs but will only sustain the current workforce at a cost of nearly £20 million per employee, a report has claimed.

A study by the influential think-tank the Jimmy Reid Foundation found that a total of 600 civilian jobs depend on the existing Trident system in Scotland, with 11,520 more spread out across the UK.

It estimates the cost of renewing Trident to be £205bn, the equivalent of £18 million per person working on the project, and says that a replacement programme would not lead to any jobs boost in Scotland.

The report also warns that replacing the UK's nuclear submarine fleet would divert engineering jobs from other sectors of the economy where they are more needed, adversely affect the defence budget for years to come and will ultimately make the world less safe.

The Jimmy Reid Foundation commissioned academics Professor Mike Danson, Karen Gilmore and Dr Geoff Whittam to prepare the report, titled 'Trident and its Successor Programme – the case for non-renewal, employment diversification and contributing to peace’, which is to be presented to the Scottish parliament today.

The probe sets out the moral and philosophical, economic and defence-orientated cases for not replacing Trident, as well as examining the impact of job losses as a result of non-renewal.

The study claimed that the system offers little to the Scottish and UK economies in the way of economic activity and knock-on effects, and threatens to become a financial black hole due to "ever-increasing" costs of procurement.

The report's authors argue that money which will be spent replacing the weapons system would be put to better use mitigating the cuts to public finances brought about by the Westminster's austerity policies, and reversing job losses as a result of reduced budgets given to local government .

It also says that the renewal programme contributes to a "continued" decline in the armed forces which has already resulted in job losses on the Clyde and other defence centres, and said that the Ministry of Defence would be able to build more Type-26 Frigates in Govan, Glasgow, if Trident was scrapped.

The authors call on the Scottish Government to establish a ‘Scottish Defence Diversification Agency’, whose remit would be to plan for the diversification of jobs away from defence projects and promoting a greener Scottish economy.

Lead author Professor Mike Danson said: ‘Our report demonstrates that far, far more is to be lost than gained by renewing Trident. Trident does not save jobs but costs jobs. Trident does not enhance our skills base but degrades it.

"Trident does not bring economic benefits ’ to the local area but leaks them away from it. All in all, renewing Trident makes neither economic nor social sense. It also an affront to democracy and humanity, and makes the world no more safe than it currently is."

Professor Gregor Gall, director of the Jimmy Reid Foundation, added: "We very much welcome this robust and rigorously researched report.

"Without a doubt, it makes the case that renewing Trident is not in the interests of the citizens of Scotland. We look forward to politicians and political parties taking up its findings and promoting them in order to do all that can be done to stop the renewal of Trident."

An MOD spokesperson said: “The Royal Navy’s £31bn Dreadnought programme provides for four submarines that will provide the ultimate guarantee of Britain’s security through to the 2060s. 

"HMNB Clyde is one of the largest employment sites in Scotland, is already home to 8200 jobs and will be the home of all of Britain’s submarines by 2022. 

"The withdrawal or cancellation of Dreadnought would have colossal implications for future shipbuilding in Scotland.”
