The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.
● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

blank = series not published for this year; – = absent from that edition.
Asked vs spent: the PB2023 book requested $25.4M for FY2023; the PB2025 book reported $27.1M as actual total obligation authority — $1.74M above the request. 27.1 − 25.4 = 1.7 USD millions — the compact figures above are rounded for reading.

Description
Mission — Free-Flyer Spacecraft Missions
America secures peace through strength, and that strength is built on an unyielding technological edge in space - an edge forged through strategic investments in the Department of Defense's (DoD) Space Test Program (STP). As the DoD's primary gateway for space experimentation to lead to space superiority, STP is a critical enabler of national security and a direct investment in deterring adversaries like China. The DoD Space Experiments Review Board (SERB) is central to STP's mission, conducting a rigorous annual review to evaluate and prioritize space experiment proposals. After being reviewed by the SERB, STP provides these cutting-edge technologies with rapid access to the demanding environment of space, accelerating their maturation into operational capabilities. This ensures our troops maintain a decisive advantage across all domains by: • Providing Access for Rigorous Testing and Evaluation: STP enables space access to test technologies, raise Technology Readiness Levels, and validate research. • Ensuring Warfighter Relevance: Through the DoD SERB prioritization, STP focuses on space technologies with direct military applications, benefiting warfighters across all domains. • Developing Future Operational Capabilities: STP matures promising space technologies into operational systems, strengthening the United States Space Force and ensuring its advantage. • Fostering Cross-Service Collaboration and Innovation: STP, DoD's space experimentation hub, fosters cross-service/agency collaboration, aligning tech priorities and minimizing redundancy. • Maximizing Value Through Collaboration: STP partners with government, commercial, and international entities to maximize taxpayer value, broaden space access, and optimize launch opportunities. STP adheres to Executive Orders 10521 and 13185, and the requirement from the Office of the Under Secretary of Defense for Research and Engineering (OUSD (R&E)) to support research, per DoD Instruction 3210.1, Administration and Support of Basic Research. In addition, the Deputy Secretary of Defense Space Test Program Management & Funding Policy, issued in July 2002, reaffirmed STP as the primary provider of spaceflight for the DoD space research community. The July 2002 policy statement also reaffirmed STP's role as the single manager for all DoD payloads on the International Space Station (ISS). This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 1206392SF and 1206398SF. The FY 2026 request was reduced by $0.283M for Advisory and Assistance Services to promote efficiencies and advance the policies of the Administration in alignment with Executive Order 14222, "Implementing the President's Department of Government Efficiency Cost Efficiency Initiative." This program is in Budget Activity 6, RDT&E Management Support because this budget activity includes research, development, test and evaluation efforts and funds to sustain and/or modernize the installations or operations required for general research, development, test and evaluation.
Justification
Accomplishments & Planned Programs (3)
Payload Integration
Integrate payloads onto spaceflight missions on the full spectrum of DoD on-orbit R&D (e.g. space vehicle, free-flyer payloads, hosted payloads, etc.). Includes acquisition of associated spacecraft and integration hardware.
Launch Vehicle and Launch Services
Purchase launch services, launch vehicles, and launch vehicle support for the full spectrum of DoD on-orbit R&D (e.g. space vehicle, free-flyer payloads, hosted payloads, etc.), enabling spaceflight worthiness and "Do No Harm" certification for Space Systems Command (SSC) and United States Space Force (USSF) HQ.
On-Orbit Satellite Operations
Execute first-year operations and operations support for STP-sponsored missions.

Follow the dollar
No follow-the-dollar view — this program's awards haven't been crosswalked at high confidence (flows cover 312 of 1,938 programs). why coverage is partial? →
Awards
No awards are linked to this program element at high or medium confidence — the budget→award crosswalk only asserts links it can defend, and this line has none yet.
Lobbying mentions
No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.
Oversight
Department-level designation (not specific to this program)
GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not Space Test Program (STP). No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
Program dossier
No research dossier for this program — dossiers cover 50 of 1,938 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
