The signals intelligence site is part of a recent deal between Moscow and Managua involving the sale of 50 T-72 Russian tanks, said defense officials familiar with reports of the arrangement.
The tank deal and spy base has raised concerns among some officials in the Pentagon and nations in the region about a military buildup under leftist Nicaraguan leader Daniel Ortega.
Disclosure of the Russia-Nicaraguan spy base comes as three U.S. officials were expelled from Nicaragua last week. The three Department of Homeland Security officials were picked up by Nicaraguan authorities, driven to the airport, and sent to the United States without any belongings.
