Saudi Arabia has entered into a 14-year, $10 billion agreement with General Dynamics’ Canadian subsidiary for an undisclosed number of military and civilian armored vehicles, Canada’s Trade Minister Ed Fast announced Friday.

The vehicles will be produced by General Dynamics Land Systems-Canada (GDLS) in London, Ontario, and the deal could be worth up to $13 billion if all options are exercised by the Saudi government.

Ken Yamashita, a spokesman for GDLS said that while the company is contractually unable to divulge the number or make of the vehicles that are part of the deal, “these will be new vehicles” and the company is “starting to do design and development work immediately,” with the first vehicles rolling off the production line in 2016.
