The maker of bulletproof vests and other products saw its shares surge 12.4% to close at a market value of about $716 million.

“The absolute size and multi-year nature of the award lays the groundwork for the defense portion of the previously announced five-year ‘Ceradyne $1 Billion’ strategy” on annual revenue, Chief Executive Joel Moskowitz said in a statement.

Ceradyne had about $400 million in revenue last year.

Ceradyne also has been pushing for revenue beyond the defense sector, with recent deals for products such as ceramic crucibles used in solar-energy panels.

The recent order for the military is set for initial deliveries next year, with completion expected in March 2013.
