Northrop Grumman and Raytheon Missiles & Defense have partnered to bid for the US Missile Defense Agency (MDA) Next Generation Interceptor (NGI) contract.

The US Department of Defense issued a request for proposal (RFP) for the NGI on 24 April this year.

The NGI programme is expected to cost nearly $11bn. Around 20 interceptors are planned to be fielded.

Testing is likely to take place between 2025 and 2026 with deployment expected for 2027-28.

Northrop Grumman Space Systems corporate vice-president and president Blake Larson said: “We have the right team, technology and expertise in place to meet our customer’s needs for enhanced capabilities, from the identification of a ballistic missile launched by an adversary, all the way to its elimination.

“Together, we will offer MDA an effective and affordable solution for defending our nation from these emerging threats.”

Currently, the two companies are involved in the supply of the interceptor booster, kill vehicle, ground systems, fire control and engagement coordination.

These systems and support are for the Ground-Based Midcourse Defense system.

The companies have jointly conducted over 40 successful exoatmospheric intercepts.

Raytheon Missiles & Defense president Wes Kremer said: “The joining of true experts, with mastery from threat detection to interception, creates a team capable of developing a revolutionary solution that is designed to defeat emerging threats.”
