The US Missile Defence Agency (MDA) has unveiled plans for the next phase of the European Phased Adaptive Approach (EPAA), the US contribution to Nato Ballistic Missile Defense (BMD).
The decision will see US Army Corps of Engineers (USACE) carry out work on the next phase of Aegis Ashore ballistic missile defence in Poland's Redzikowo Air Base in 2017.
The plans follow the US Department of Defence's (DoD) decision to deploy the land-based BMD facility to the Polish base, which will protect European Nato allies and US forces in the region against growing ballistic missile threats from the Middle East.
Two major construction contracts are scheduled to be awarded on the third phase in Poland.
USACE Europe District Missile Defense Branch chief Curt Heckelman said: "The first is a $100m to $200m contract to build the missile-defence facilities. We already have proposals and expect to award a contract this February.
"The second is a $25m to $100m contract to build the offices, housing and other facilities where US Navy personnel will work and live. We are currently accepting proposals, and this contract is open to all major construction companies."
Construction of the new facility, which will be assigned 300 US military personnel, is expected to be completed by 2018.
Phase three will involve development of SM-3 Block IIA missiles, for deployment from Aegis Ashore sites in Romania and Poland, as well as Aegis BMD ships, by 2018.
Phase four will see delivery of SM-3 Block IIB missiles by 2020 to defend IRBMs and ICBMs.
