Multi-Orbit Logistics Services

Project Description

In anticipation of future missions, the Department of Defense seeks logistics services enabling low cost, responsive access to geostationary (GEO) and other exotic orbits beyond low Earth orbit (LEO).  For the purposes of this solicitation, a multi-orbit logistics vehicle (m-OLV) should be capable of autonomously transferring payloads or spacecraft to, within and between LEO, GEO, cislunar and other exotic orbits. Desired solutions should provide commercial services in the form of deep-space capable orbit transfer vehicles, fuel depots or other in-orbit mission enhancement opportunities.


Minimum desired capabilities, by category (Note: Please clearly specify the relevant category for each submission. Multiple submissions may be submitted by the same team.):

  1. Light utility m-OLV: capable of transporting (hosting) one or more mechanically-coupled payloads (~50 kg payload capacity).  The vehicle should have sufficient propellant capacity to transport one payload from LEO to GEO with guidance and control to support cooperative rendezvous, proximity operations, and release of its payload at the end of the transit.  
  2. Heavy utility m-OLV: capable of transporting (hosting) one or more mechanically-coupled payloads or spacecraft (500+kg payload capacity).  Sufficient propellant for persistent operations and maneuver to another orbit. The vehicle should include guidance and control to support cooperative rendezvous, proximity operations, and berthing with a space outpost or servicer.   
  3. Fuel depot: capable of storing and transferring sufficient chemical and/or electrical propellant to a m-OLV or self-propelled satellite to achieve a LEO-to-GEO transfer. The depot should include the necessary mechanisms, sensors and controls to couple the customer vehicle to the depot for refueling. 
  4. Rideshare approach: provide transport of detachable payloads or propellant to an m-OLV or an Outpost in GEO, cislunar or other exotic orbit. 

The following factors will be strongly considered during the selection process:

  • The architecture associated with the proposed concept
  • Description of onboard use of robotic systems or interaction with external robotic systems such as those on a fuel depot or Outpost 
  • Reusability and flexibility to support multiple mission sets and multiple transits (m-OLV)
  • Robotic capture of a less than fully coordinated free-flying target (m-OLV)
  • The ability to be refueled (m-OLV and depot)
  • Use of available/common grapple fixtures, interfaces and trusted components
  • Ability to facilitate self-disposal at the end of mission or service life
  • Ability to integrate with multiple space missions across various domains in the burgeoning new space economy
  • Commercial viability of business case
  • Cost savings and responsiveness over the current GEO/deep-space paradigm
  • Team experience and willingness to collaborate with other commercial entities

The prototype and its pricing should be considered independent of launch cost.


This effort will be a multi-phased effort. The first phase will include a systems engineering study to assure interoperability and completeness of a multi-orbit logistics infrastructure with other efforts. Subsequent phases will focus on employment and demonstration of on-orbit capabilities. Prototype hardware should be ready for flight within 36 months of contract award.


The government may facilitate teaming arrangements among submissions offering complementary capabilities to achieve desired effect.  Companies are also welcome to present their own teaming arrangements in their solution briefs.


Questions during the solicitation period will be entertained until 13 February 2020. Answers will be posted as appropriate on this page.

Awarding Process


Before You Submit

Companies are advised that any Prototype Other Transaction (OT) agreement awarded in response to this solicitation may result in the direct award of a follow-on production contract or agreement without the use of further competitive procedures. Follow-on production activities will result from successful prototype completion.

The follow-on production contract or agreement will be available for use by one or more organizations within the Department of Defense. As a result, the magnitude of the follow-on production contract or agreement could be significantly larger than that of the Prototype OT agreement. All Prototype OT agreements will include the following statement relative to the potential for follow-on production: “In accordance with §10 U.S.C. 2371b(f), and upon a determination that the prototype project for this transaction has successfully been completed, this competitively awarded Prototype OT agreement may result in the award of a follow-on production contract or transaction without the use of competitive procedures.”

We Work With You

If we think there’s a good match between your solution and our DoD partners, we’ll invite you to provide us with a full proposal — this is the beginning of negotiating all the terms and conditions of a proposed prototype contract.

After a successful prototype, the relationship can continue and even grow, as your company and any interested DoD entity can easily enter into follow-on contracts.

Our Process

  1. We solicit commercial solutions that address current needs of our DoD partners.

  2. You send us a short brief about your solution.

  3. We’ll get back to you within 30 days if we’re interested in learning more through a pitch. If we're not interested, we'll strive to let you know ASAP.
