The £1.5 billion investment will be included in the Strategic Defence Review, a 10-year plan for military equipment and services. The SDR is expected to be published tomorrow.

The ministry of defence added that it planned to procure up to 7,000 long-range weapons built in Britain. Together, the measures announced yesterday will create around 1,800 jobs, the MoD said.

“The hard-fought lessons from (Russian President Vladimir) Putin’s illegal invasion of Ukraine show a military is only as strong as the industry that stands behind them,” defence secretary John Healey said in a statement.

“We are strengthening the UK’s industrial base to better deter our adversaries and make the UK secure at home and strong abroad.”

The extra investment will mean Britain will spend around £6 billion on munitions in the current parliament, the MoD said.

Earlier on Saturday, the MoD said it would spend an extra £1.5 billion to tackle the poor state of housing for the country’s armed forces.
