2.0 Notional SBI Architecture
The Government defines the following SBI architecture elements that are used throughout this RFI.
- Space-based Interceptors are a class of weapon systems designed to intercept and destroy enemy targets (missiles or associated payloads) in flight. This element comprises multiple variants and components:
- Exoatmospheric SBIs are designed to destroy targets in the boost and mid-course phases outside the Earth’s atmosphere (above 120 km), employing a kill vehicle (KV), guidance and navigation systems, communications, and propulsion for both initial engagement and terminal guidance maneuvers.
- Endoatmospheric SBIs are designed to destroy targets within the Earth’s atmosphere (below 120 km), employing a KV, guidance and navigation systems, communications, and propulsion for initial engagement and terminal guidance maneuvers while accounting for atmospheric effects.
- Terminal Guidance enables the SBI to acquire and track the target autonomously after weapon release from its host satellite, executing precise maneuvers during the final phase of flight to achieve a successful intercept.
- In-Flight Target Update provides the ability to modify the SBI’s target information while it is in flight, based on new sensor data or changes in the threat trajectory.
- Host Satellite is a space-based platform that provides power, communication, and other essential services to the SBI payload while on orbit prior to the initiation of an intercept.
- SBI Common Ground Element (CGE): The CGE serves as the central command and control hub for generating and sending commands to the SBI constellation, receiving telemetry and messages from the SBI constellation, and controlling and managing communications links to the SBI constellation through the Space Data Transport Layer and antenna services. These functions are automated to the maximum extent possible. The CGE manages a large constellation of several interceptor variants (multiple exoatmospheric and endoatmospheric variations from multiple vendors) in a variant- and vendor-agnostic manner using an open commanding and telemetry database scheme. CGE ensures constellation health and status, safety, and continuity of operations. This includes autonomous station-keeping and constellation configuration adjustment required due to anomalies to minimize coverage gaps and maximize SBI constellation effectiveness, all with minimal or no operator intervention. It also exchanges commands, orders, and messages with the Fire Control Element as well as integrates data from diverse sources, including the Ground/Space Battle Management Element (GSBME). When directed by the President and commanded by the Fire Control Element, CGE will enable weapons for release and command intercepts computed by the Fire Control Element.
- SBI Fire Control Element (FCE): The FCE ingests fire control-quality data from the missile warning/missile track sensor layers and SBI constellation health and status from the CGE. FCE conducts combat identification based on intelligence-based order of battle and real-time sources and performs weapon-target pairing based on rules of engagement to prioritize and engage multiple simultaneous targets. The FCE calculates the predicted intercept point for the assigned SBI, commands weapon release and continuously reassesses target track data to develop and send in-flight target updates (IFTUs) to the SBI until the SBI switches to on-board terminal guidance.
- Architectural elements external to and not covered by this RFI include:
- Space Data Transport Layer provides 24/7 telemetry, tracking, and command (TT&C) services to the SBI constellation and the CGE and delivers IFTUs to interceptors after weapons release, ensuring continuous communication and effective engagement.
- Ground/Space Battle Management Element (GSBME) serves as the central orchestration and decision-making node for integrated missile defense across all missile defense layers, receiving threat data, assigning targets to respective missile defense layers, overseeing battle damage assessment to determine engagement effectiveness, and orchestrating re-engagement actions as necessary to ensure complete threat negation across the battlespace. GSBME requires robust automation and machine-to-machine integration with the SBI CGE and FCE for timely and effective responses.
3.0 Areas of Interest
The Government is seeking industry’s innovative solutions to establish a proliferated SBI constellation in a quick and efficient manner. Solutions that leverage commercial products, processes, and services are of interest to the extent they maximize mission effectiveness and minimize cost-per-kill and time to field.
