Budget figures
$53.2M discretionary + $18.0M one-time reconciliation. Discretionary change vs FY2025 enacted: +28.0%.
Two official figures, one label— reconciled below
Fiscal Receipts uses P-1/R-1 workbook total obligation authority (TOA) as the headline figure sitewide. The workbook TOA includes budget rows that the R-2/P-40 J-book program line excludes — advance procurement in an ordinary year, and in FY2026 the one-time reconciliation appropriation as well. Each row below names the one it is. How the two bases relate →
FY26 Request · $71.2M TOA − $53.2M J-book line = 18.0M (71.2 − 53.2 = 18.0) — $18.0M of one-time FY2026 reconciliation money accounts for this gap — not advance procurement
Figures in the sentence are rounded for reading; the parenthesised arithmetic is the same subtraction in USD millions, at the precision where it closes.
FY2026 award data is a partial year — USAspending reports awards on a rolling basis, and this corpus runs through 2026-09-04. why partial FY2026 data? →

Description
Mission — Radar Development
Project E10: The FY2026 request for Sentinel includes $18,853 thousand of discretionary and $14,000 thousand of mandatory (reconciliation) for a total of $32,853 thousand. The discretionary funds will support enhancements, upgrades, and continued testing of the Army Modernization Priorities in support of the Sentinel Radar programs and will provide for an incrementally fielded Integrated Air and Missile Defense Fire Control System/capability for the composite Army Air and Missile Defense Brigades. The mandatory funds will develop and implement new signal processing techniques and waveforms to enhance Electronic Attack and Electronic Protect techniques based on the evolving threat, further enhancing radar survival and effectiveness in contested environments. Further information for this reconciliation request is provided in Section 20003 (Missile Defense) of the Reconciliation Exhibit. The Sentinel systems are a key component of the Army Integrated Air and Missile Defense (AIAMD) architecture, providing critical air surveillance of the forward areas. Project PS1: The FY2026 request for the Army Long-Range Persistent Surveillance (ALPS) includes $34,373 thousand of discretionary and $4,000 thousand of mandatory (reconciliation) for a total of $38,373 thousand. The discretionary funds will support the Army Long-Range Persistent Surveillance (ALPS) sensor, which is a persistent, passive air surveillance sensor system. ALPS capabilities include long-range, 360-degree surveillance against conventional fixed wing and rotary wing aircraft, UAS, and cruise missiles. ALPS supports tactical to strategic operations via its capability to connect with multiple Army and Joint Command and Control systems including the Integrated Fire Control Network (IFCN). The mandatory funds will develop Fixed Site capability for defense of the homeland. Further information for this reconciliation request is provided in Section 20003 (Missile Defense) of the Reconciliation Exhibit. The ALPS program tasks include all programmatic and engineering activities needed to modernize systems currently supporting multiple Combatant Commands and design/development effort to provide a passive capability to Army Air and Missile Defense forces in accordance with the requirements in the Capability Development Document (CDD). The total program element FY2026 request is $53,226 thousand of discretionary and $18,000 thousand of mandatory reconciliation for a total of $71,226 thousand. Further information for this reconciliation request is provided in Section 20003 (Missile Defense) of the Reconciliation Exhibit. The FY 2026 request was reduced by $0.117 million 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."
Mission — Sentinel
The FY 2026 request for Sentinel includes $18,853 thousand of discretionary and $14,000 thousand of mandatory (reconciliation) for a total of $32,853 thousand. The discretionary funds will be used to support enhancements, upgrades, and continued testing of the Army Modernization Priorities in support of the Sentinel Radar programs and will provide for an incrementally fielded Integrated Air and Missile Defense Fire Control System/capability for the composite Army Air and Missile Defense Brigades. The mandatory funds will develop and implement new signal processing techniques and waveforms to enhance Electronic Attack and Electronic Protect techniques based on the evolving threat, further enhancing radar survival and effectiveness in contested environments. Further information for this reconciliation request is provided in Section 20003 (Missile Defense) of the Reconciliation Exhibit. The Sentinel systems are a key component of the Army Integrated Air and Missile Defense (AIAMD) architecture, providing critical air surveillance of the forward areas. The Sentinel A4 utilizes Active Electronically Scanned Array (AESA) technology that is a ground-based sensor system designed to locate, identify and track Cruise Missiles, Fixed-Wing and Rotary-Wing Aircraft, Unmanned Aircraft Systems and Rocket, Artillery, and Mortar (RAM) projectiles. The multi-mission Sentinel A4 system will provide 360-degree surveillance and tracking with the ability to handle multiple simultaneous threats arriving from different azimuths. The Sentinel A3 consists of a trailer mounted radar with its prime mover, generator, identification Friend or Foe (IFF) system and Forward Area Air Defense Command, Control and Intelligence (FAAD C2I) systems interface. The Sentinel A3 provides persistent surveillance and fire control quality data on Army and Joint networks through external C2 platforms enabling protection of U.S. and coalition forces as well as critical geo-political assets against Cruise Missiles (CM), Fixed-Wing, Rotary-Wing Aircraft and Unmanned Aircraft System (UAS) threats.
Mission — Army Long Range Persistent Surveillance (ALPS)
The FY2026 request for ALPS includes $34,373 thousand of discretionary and $4,000 thousand of mandatory (reconciliation) for a total of $38,373 thousand. The discretionary funds will support the Army Long-Range Persistent Surveillance (ALPS) sensor, which is a persistent, passive air surveillance sensor system. ALPS capabilities include long-range, 360-degree surveillance against conventional fixed wing and rotary wing aircraft, UAS, and cruise missiles. ALPS supports tactical to strategic operations via its capability to connect with multiple Army and Joint Command and Control systems including the Integrated Fire Control Network (IFCN). The mandatory funds will develop Fixed Site capability for defense of the homeland. Further information for this reconciliation request is provided in Section 20003 (Missile Defense) of the Reconciliation Exhibit. The ALPS program was started as an urgent capability in response to multiple Combatant Commands identified operational needs. The ALPS program tasks include all programmatic and engineering activities needed to modernize systems currently supporting multiple Combatant Commands and design/development effort to provide a passive mobile capability to Army Air and Missile Defense forces. In FY 2025, Project PS1 /Army Long Range Persistent Surveillance (ALPS) was a new effort realigned within PE 0604820A / Radar Development.

Contractor concentration
No concentration index is published for this line. This line's high-confidence links do not clear the floor for a published concentration index — at least 3 awards across 2 contractor families holding positive obligations, with positive net linked dollars. An index below that floor is a fact about the sample, not about the market. Whatever further links this line carries are medium-confidence, and what each medium evidence path does and does not establish is set out in the methodology. Both bases are in the downloadable warehouse.
Lobbying mentions
No Senate LDA lobbying filing in the tracked data mentions this program element by code or alias.
