Missile Defense Agency Releases RFP for Next Generation Interceptor (NGI)

The U.S. Missile Defense Agency (MDA) has released the Request for Proposal (RFP) for the Next Generation Interceptor (NGI) program on April 24.

The NGI solicitation allows contractors 90 days to provide proposals to the Government beginning 1 May 2020 and calls for proposal receipt of 31 July 2020.

“MDA understands the concerns with releasing an RFP during the COVID-19 crisis and has been in communication with NGI prime offerors to assess their availability to receive and evaluate the RFP. As Departmental guidance changes, adjustments for COVID-19 may occur based on Real World Events”, said the RFP.

“The NGI program requires access to classified information up to TOP SECRET and safeguarding at SECRET. Interested Prime Offerors must have an approved Facility Clearance in accordance with the National Industrial Security Program Operating Manual (DoD 5220.22-M) and be able to appropriately courier/transport electronic media classified up to TOP SECRET”, the RFI added.

The Next-Generation Interceptor (NGI) program replaces the canceled Redesigned Kill Vehicle (RKV) program which was terminated by the Under Secretary of Defense (Research and Engineering) Dr. Michael Griffin in August 2019 subsequent to the submission of the fiscal year 2020 budget request.

Unlike the RKV program which sought to replace just the kill vehicle (Exoatmospheric Kill Vehicle (EKV)) of the Ground-Based Interceptor (GBI) missiles, the NGI program will replace the entire GBI interceptor. The GBI interceptor missiles are part of the Ground-based Midcourse Defense (GMD) system which is designed to defend the U.S. from long-range ballistic missile attacks.

Once operationalized, the NGI will be the core of DOD’s ground-based interceptor system for homeland


The Ground-based Midcourse Defense (GMD) system is the United States’ only operationally deployed missile defense program capable of defending the entire U.S. homeland (including Alaska and Hawaii) against long-range ballistic missile attacks.

GMD is designed to detect, intercept and destroy long-range ballistic missiles during their midcourse phase of flight. The system provides early detection and tracking during the boost and midcourse phase, as well as target discrimination, precision intercept and destruction of the target through force of collision. GMD is an integral element of the U.S. Missile Defense Agency’s layered ballistic missile defense architecture.

The GMD system is deployed at Fort Greely, Alaska and Vandenberg Air Force Base, California comprising 44 GBI interceptors. As prime contractor, Boeing designs, produces, integrates, tests and sustains all GMD components deployed across 15 time zones.


The Ground-Based Interceptor is a multi-stage, solid fuel booster with an EKV payload. When launched, the booster carries the EKV toward the target’s predicted location in space. Once released from the booster, the EKV uses guidance data transmitted from Ground Support & Fire Control System components and on-board sensors to close with and destroy the target warhead. The impact is outside the Earth’s atmosphere using only the kinetic force of the direct collision to destroy the target warhead.
