Tetra Tech announced it was awarded a contract for the missile defense agency Scalable Homeland Innovative Enterprise Layered Defense, or SHIELD, indefinite-delivery and indefinite-quantity contract. The contract has a ceiling of $151B and encompasses a broad range of work areas to allow for the rapid delivery of innovative capabilities to the warfighter with speed and agility.
