A team of Birmingham-based experts from law firm Wragge & Co has been appointed to advise the Ministry of Defence on the £3 billion project to build two 'super carriers' for the Royal Navy.
But observers believe the project to build the new vessels, named HMS Queen Elizabeth and HMS Prince of Wales, could be prone to time and cost overruns.
The Government named Kellogg Brown & Root as "physical integrator" for the project.
But the firm's role was scaled back after alliance partner BAE Systems, Britain's largest defence contractor, threatened to quit.
BAE expressed concerns that Kellog Brown & Root would use its role to lobby for the 60,000-tonne carriers to be built at Nigg, its offshore facility in the north of Scotland.
However, the site, mothballed for a number of years, has since been put up for sale.
Infrastructure partner Michael Whitehouse will lead the Wragge team.
