(NXTL)

scored a Navy cell-phone supply contract that could be worth as much as $100 million over five years.

The Reston, Va., wireless service provider said the contract provides nationwide commercial cellular phone and instant digital walkie-talkie service for personnel at U.S. installations. Nextel said options could extend the yearlong pact by as many as four years.

"The size and scope of this Navy contract is a major milestone for Nextel and another in a series of powerful proof points demonstrating the performance and value of Nextel's mobile technology," said Nextel's Leon Frazier. "This contract will enable Navy personnel in Virginia, for example, to use Nextel's push-to-talk capabilities to communicate with personnel in Hawaii, thus realizing the greatest value of Nextel's leading-edge technology."

Nextel said its public sector segment accounts for some 15% of the company's 14 million customers.

On Monday, Nextel rose 43 cents to $28.27.
