L-3 Communications Holdings Inc., a New York-based provider of translators to the U.S. Army, said fourth-quarter earnings rose 19 percent on demand for linguists and surveillance equipment.

Net income climbed to $207 million, or $1.63 a share, from $174 million, or $1.37, a year earlier, beating analysts' estimates by 1 cent. Sales rose 12 percent to $3.81 billion, L-3 said Thursday in a statement.

L-3 has a Salt Lake City division, Communications-Systems West, that employs 2,300 people.

A 29-percent sales gain in the surveillance unit helped fuel revenue on demand for intelligence equipment and communications systems. Earnings were lifted by an extension of a disputed $4.6 billion contract to provide linguists in Iraq. The company expanded L-3's work as a prime contractor and won contracts with the Army, Air Force, and National Weather Service during the quarter.

L-3 rose $2.53, or 2.4 percent, to close at $110.38 on Thursday. The stock has gained 34 percent in the past 12 months.
