Space Access, Mobility & Logistics (SAML)

The Servicing, Mobility, and Logistics (SML) program focuses on enhancing space-related mobility and logistics capabilities. It aims to integrate and employ on-orbit servicing and mobility for spacecraft. Key objectives include on-orbit refueling, repair, upgrade, assembly, manufacturing, orbit repositioning, sustained maneuvering, and autonomous Rendezvous, Proximity Operations & Docking (RPOD). The program also covers operations beyond geostationary orbit and sub-orbital and orbital point-to-point delivery. The immediate goal is to establish foundational capabilities through research, development, testing, evaluation (RDT&E), technology demonstrations, operational integration, and fielding of Point to Point Delivery (P2PD) services.

The On-Orbit Servicing, Mobility & Logistics (OOSML) project within the SML program is designed to enhance asset availability for the warfighter by advancing support capabilities in space. This project emphasizes developing a service architecture that allows systems to replenish energy as needed. It aims to remove constraints imposed by fixed fuel limitations and enable dynamic space operations for critical national security assets. The OOSML project also focuses on integrating commercially available servicing technology into operational capabilities through prototyping modified commercial off-the-shelf systems.

The Point-to-Point Delivery (P2PD) project builds upon prior work within the Rocket Cargo Vanguard program to develop prototype systems for unique military use cases. This initiative seeks to integrate relevant technologies from science and technology efforts into high-TRL prototypes that demonstrate military applications. Near-term goals include establishing foundational capability areas through operational integration and fielding of P2PD services. It involves developing prototype air drop delivery systems and certifying additional service providers.

The SML program provides a cost-effective approach to leveraging commercial space systems with high Technology Readiness Levels to meet Department of Defense needs. Activities under this program include system engineering technology maturation, tactics development for operational integration, prototyping, testing, and evaluation required for transitioning technologies into effective operational employment. The program aims to rapidly address capability gaps with emerging technologies while supporting U.S. national security objectives in a competitive global environment.
