LONDON, Oct 1 (Reuters) - Britain's ministry of defence said on Saturday that construction work will begin on the country's new nuclear submarines, announcing nearly 1.3 billion pounds ($1.7 billion) of new investment with defence firm BAE Systems BAES.L .
Lawmakers backed renewing Britain's ageing nuclear weapons system earlier this year, a multi-billion pound project regarded as key to maintaining the country's status as a world power following its vote to leave the European Union. investment will support delivery of the Government's commitment to retain the Trident-based continuous at sea deterrent - the ultimate guarantee of our safety - and build the new fleet of four Successor Ballistic Missile submarines," the defence ministry said in a statement.
BAE Systems said the first new submarine will enter service in the early 2030s.
