Deorbit as a Service

**Problem Statement** The U.S. Department of War (DoW) lacks a scalable autonomous capability to safely interact with unprepared satellites (defined as space vehicles not designed for third-party interaction or controlled end-of-life disposal) in order to execute reliable deorbit operations. As proliferated constellations expand, satellites that experience anomalies or reach the end of mission persist in orbit as hazards that constrain maneuver space, increase collision risk, and degrade mission resilience.
Without a deliberate means to remove these satellites, the DoW remains dependent on potentially multi-decade natural orbital decay followed by replacement launches, limiting operational flexibility. Addressing this gap requires solutions that can safely engage unprepared satellites to enable controlled deorbit while also establishing a foundation for future space interaction and sustainment missions.
Desired Solution Attributes
The DoW seeks solutions that enable the rapid, safe, and reliable deorbit of unprepared satellites. Desired solutions must reduce orbital congestion and sustain proliferated orbit operations by enabling a deorbit even after loss of command or catastrophic system failure. While some approaches may involve active interaction with a client satellite, the DoW prioritizes solutions that minimize operational complexity and reliance on continuous ground control. Solutions should be scalable, resilient, cost-effective, and capable of operating across diverse orbital conditions as constellation density increases. Although deorbit is the primary objective, the ability to safely interact with unprepared satellites also establishes a foundation for secondary missions that involve “to, through, and from” operations, providing additional flexibility and long-term benefit to U.S. space operations.

Vendor Solution Brief Submission Options
Vendors have flexibility in how they submit their solution briefs, which can be proposed either independently or through a teaming arrangement.
Process
Submissions will be evaluated in accordance with CSO HQ084520SC001 available on https://DIU.mil and https://SAM.gov. Vendors selected for Phase 2 will receive an amplification letter with expanded details to help inform their Phase 2 pitches. Those vendors will be expected to provide their Rough Order of Magnitude ROM) cost breakdown. The vendorsʼ Phase 2 pitch shall address the Phase 2 evaluation factors contained in CSO HQ084520S C001. DoW requires companies without a CAGE code to register in SAM https://SAM.gov if selected for an agreement award. The Government recommends that prospective companies begin this process as early as possible. • Provide a complete system-level deorbit solution, inclusive of both hardware and software, that is adaptable to a wide range of client satellite configurations. • Deliver test reports within 90 days of award, showing functional integrated hardware and software validated in relevant test environments to perform precise Rendezvous and Proximity Operations (RPO) and/or other deorbit functions using a controlled and safe execution method. • Prove sufficient technical and manufacturing maturity to support prototyping and on-orbit demonstration to deorbit an unprepared space vehicle within 18 to 24 months. • Include a high-level description of the planned CONOPS, including the technologies used during key stages. • Provide a high level Safety CONOPS for all proximity operations, including planned approach and ingress trajectories, fault management architecture, and collision avoidance and protection measures. • Minimize risk to other spacecraft and the terrestrial environment against cooperative and non-cooperative space vehicles. • Be compatible with a range of client space vehicle sizes, configurations, and mission architectures. • Meet CNSSP-12 and CUI level cyber (NIST 800-171) requirements within 1 year of ATP. • Cost efficiency per client spacecraft deorbit and sustaining capability (including launch, deployment, operations, sustainment, and end-of-life disposal). • Extended operational life and survivability for servicer spacecraft and/or assets required to conduct deorbit operations at altitudes and inclinations ranging from LEO to GEO. • Ability to communicate spacecraft deorbit operation CONOP, performance, and effects through computational modeling and simulation • Spacecraft delta-V (ability to deorbit multiple spacecraft over operational life). • Timeline to on-orbit demonstration. • Timeline to achieve Initial Launch Capability (ILC) of the deorbit system. • Timeline to initiate deorbit operations (within a number of weeks, days, or hours of tasking) once the solution is in orbit. • Ability to adapt trajectories and operations in response to changing orbital dynamics or mission requirements. • Persistence in a staging orbit for extended durations while maintaining readiness. • Redundancy and fault tolerance when interacting with non-cooperative client space vehicles. • Identifying the readiness of individual components and/or subsystems, and describing methods of increasing the readiness of low TRL components within the period of performance. • A demonstrated willingness and ability to team with other companies offering complementary expertise to deliver an integrated deorbit capability. • Effective collaboration with government stakeholders and commercial partners. • Evidence of prior production, launch, or on-orbit execution supporting scalability and near-term implementation. • Suitability for rapid, scalable production and commercial rideshare launch with proven manufacturability and integration readiness, including a credible plan for transition beyond the prototype phase, supporting sustained operations and long-term viability. • Flexible business model (e.g., De-orbit as a Service) enabling the government to procure capability only as needed and without the added overhead costs associated with a government-owned and government-operated (GOGO) system. • Additional value-added features or methodologies that enhance the proposed solution’s effectiveness or efficiency in meeting the program objectives and that are not otherwise captured in the differentiators.
**Eligibility Requirements** Eligibility
This solicitation is open to U.S. and international vendors. Vendors are reminded that in order to utilize an Other Transaction agreement, the requirements of 10 USC 4022 must be satisfied. Specifically reference 10 USC 4022(d), which requires significant contribution from a nontraditional defense contractor, all participants to be small business concerns, or at least one third of the total cost of the prototype project is to be paid out of funds provided by sources other than the Federal Government.
Awarding Instrument
This Area of Interest solicitation will be awarded in accordance with the Commercial Solutions Opening CSO) process detailed within HQ085420SC0001 DIU CSO, posted to SAM.gov in March 2020.
Follow-on Production
Companies are advised that any prototype Other Transaction OT) agreement awarded in response to this Area of Interest may result in the award of a follow-on production OT agreement or contract without the use of further competitive procedures. The follow-on production OT agreement or contract will be available for use by one or more organizations in the Department of War and, as a result, the magnitude of the follow-on production OT agreement or contract could be significantly larger than that of the prototype OT. As such, any prototype OT will include the following statement relative to the potential for follow-on production: "In accordance with 10 U.S.C. § 4022(f), and upon a determination that the prototype project, or portions thereof, for this transaction has been successfully completed, this competitively awarded prototype OT agreement may result in the award of a follow-on production OTA or contract without the use of competitive procedures.ˮ
