Ceradyne receives armor order

Ceradyne Inc. has received a $21.9 million order for light-weight body armor from the Defense Supply Center Philadelphia.

The armor is known as ESAPI, or enhanced small arms protective inserts. It will be delivered by March 31. The order is part of a three-year federal contract issued in December 2007, Ceradyne said Wednesday.

The company makes the armor at one of its two ceramics plants in Lexington and also at a plant in California where Ceradyne is based. The stock is listed by Nasdaq as CRDN.
