General Dynamics in Oakdale welcome defence order
The Ministry of Defence is set to sign a £3.5bn deal for nearly 600 new armoured vehicles ahead of the Nato summit in Wales.
The MoD will sign the order for 589 Scout Specialist Vehicles at General Dynamics in Caerphilly county.
David Cameron said the deal would aid UK security and "underpin" many jobs.
At the two-day summit in Newport, due to start on Thursday, the UK will call for increased defence spending by some of Nato's 28 member states.
Mr Cameron said the Scout deal would be the Army's largest single order for armoured vehicles for more than 30 years.
It is expected to bring work for the company, which employs 200 people at Oakdale, work for the next decade.
Kevin Connell, vice president of General Dynamics UK, who runs the Scout SV programme, explained what the vehicle was about and how the Nato summit was also presenting them with a "golden opportunity" to showcase it.
