Description

Mission pLEO SATCOM (MILNET)

In FY 2026, 236.720M was erroneously transferred from PE 1203154SF, Project 671113, Auxillary Payloads to Project 670009: Auxillary Payloads. Mission descriptions and justifications are contained in PE 1203154SF. The funds will be transferred back for proper execution following enactment. In FY 2026, 40.687M was erroneously transferred from PE 1206427SF, Project 645601 / Space Defense Capabilities (Title: Space-To-Space Communications) to Project 670010: Space-To-Space Communications. Mission descriptions and justifications are contained in PE 1206427SF. The funds will be transferred back for proper execution following enactment. This program is in Budget Activity 7, Operational System Development because this budget activity includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate production funding in the current or subsequent fiscal year.

Mission Auxillary Payloads

In FY 2026, funds were erroneously transferred into Program Element (PE) 1203609SF, pLEO SATCOM (MILNET) from PEs 1203154SF, Long Rang Kill Chains & 1206427SF Space Systems Prototype Transitions. This funding will be realigned back to PE 1203154SF & 1206427SF for proper execution following enactment.

Mission Space-to-Space Communications

In FY 2026, funds were erroneously transferred into Program Element (PE) 1203609SF, pLEO SATCOM (MILNET) from PEs 1203154SF, Long Rang Kill Chains & 1206427SF Space Systems Prototype Transitions. This funding will be realigned back to PE 1203154SF & 1206427SF for proper execution following enactment.

Justification

Accomplishments & Planned Programs (2)

Space-to-Space Communications

Continue development of optical communication terminal prototypes through Other Transaction Agreements and fund the Optical Terminal Verification Testbed at Massachusetts Institute of Technology Lincoln Laboratory (MIT/LL). Develop interface controls and integration plans in preparation for a space-based prototype demonstration. Mature networking management of optical crosslink terminals in partnerships with other organizations. Enhance the DARPA Space-Based Adaptive Communication Node (SpaceBACN) modem design to support long-range crosslinks and incorporate emerging optical waveform standards.

Auxillary Payloads

The Auxiliary Payloads project will continue to leverage relationship with NRO partner to develop and field GMTI system

No follow-the-dollar view — this program's awards haven't been crosswalked at high confidence (flows cover 17 of 1741 programs). why coverage is partial? →

Awards

No awards are linked to this program element at high 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.

No research dossier for this program — dossiers cover 50 of 1741 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
