Northrop Grumman Corp. received a $15.6 million contract boost from the Navy to provide aircraft data management services on the E-2D Hawkeye, the Pentagon said late Monday.

Work will be performed in Bethpage, N.Y., Grand Rapids, Mich. and other locations and is expected to be completed by July 2012.

Shares of the Los Angeles-based company added $1.56, or 3 percent, to close at $53.93.
