McLean-based government services contractor DynCorp has not been re-selected for two contracts worth a combined $71 million with the Vienna-based National Media Exploitation Center, a little-known arm of the Defense Intelligence Agency.

DynCorp performed intelligence support services for NMEC over a five-year period beginning in 2009, according to the company and DIA. The contracts were up for renewal this year, the agency said. Chantilly-based contractor TASC has been awarded a new five-year contract worth $27 million to perform the majority of work DynCorp did, while the remainder of the work is open to small business bids, an agency spokesman said.

DynCorp’s contract will terminate at the end of this month, and the fate of 64 DynCorp employees who worked on it is unclear, a company spokeswoman said.

The center’s mission is to “exploit documents and electronic media captured on the battlefield to gain insight into adversary intentions and capabilities,” according to a 2009 award announcement from contractor ManTech, which also performed work for the center.

The news is the latest blow to a company that is already struggling. DynCorp lost bids on two major contracts last quarter because executives said competitors offered lower prices.

Details about the loss of the NMEC contract were reported earlier by the Washington Business Journal.
