What the FY2027 request buys
Verbatim from the R-2A exhibit for project 657LEO of PE 1206446SF. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
Tranche 1 - Continue integration with Missile Warning/Missile Tracking/Missile Defense (MW/MT/MD) enterprise data interfaces and fusion applications. - Continue space vehicle command and control, and enterprise management, and sustainment for all Tracking Layer Tranche 1 (TRKT1) satellites. - Complete system level verification. - Complete Operational Testing of TRKT1 capabilities including flight demonstrations and exercise participation. - Provide continuing operational support to resilient space Tracking mission including Missile Warning, Missile Tracking, and Missile Defense (MW/MT/MD). - Continue to support investments in facilities, hardware, network management, Ground Entry Points (GEPs), Optical Ground Terminals (OGT), software development, mission payloads, contract services, and any other integration requirements to support the MW/MT/MD enterprise.

FY 2027 increases from FY 2026 to reflect the ramp up of Tranche 3 space vehicle production to prepare for launch in FY 2029, support for Space-Based Sensing for Hypersonic Fire Control, and initial Tranche 4 acquisition tasks.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 1,697.8 |
| FY2026 | Enacted | 1,695.5 |
| FY2027 | Request | 3,564.2 |
This activity is 100% of project 657LEO's FY2027 request and 100% of PE 1206446SF's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
