The nation’s top three wireless carriers this week received a nearly $200 million contract from the U.S. Navy to provide services for the armed forces and federal agencies.

Under the $198.7 million deal, Verizon, AT&T and T-Mobile will deliver wireless devices and service to the Army, Navy, Air Force and Marine Corps, as well as Defense Department agencies and other government entities.

The initial contract provides a one-year base period with an option for four additional years that, if exercised, would bring the total value of the contract to $993.5 million through late 2022.

The Defense Department did not indicate how the carriers would split the work on the contract, which will be performed “at various locations throughout the U.S.”

The winning bid beat out four other offers, according to a statement.
