Astrium has signed a teaming agreement with Raytheon to compete for Nato's ballistic missile defence (BMD) programme.
The team will compete for the role of lead system engineers and integrators for programme, which oversees the development and execution of ballistic missile defence capabilities.
The programme expanded in 2012 to include the defence of European populations and territories.
Astrium Missile Defense and Nato programmes head Yannick Devouassoux said: "The Astrium-Raytheon team will provide sound, innovative, and cost-effective solutions to help develop Nato's future ballistic missile defence capability."
Raytheon Missile Systems European Missile Defense director George Mavko said: "Combined with Raytheon's decades of experience in ballistic missile defence interceptors, radars and space sensors, this partnership will provide Europe the best, most affordable missile defence protection."
The contract, upon awarded, will include a seven-year period of performance and an estimated value of €67.6m ($91m).
In addition to establishing the contractual requirements for territorial defence, the NATO BMD system engineering and integration contract helps create a NATO command and control network architecture for Europe.
The order will also provide a test infrastructure for the new architecture.
