What project PS1 buys
The FY 2027 request for ALPS includes $25.042 million of funding. These 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). In FY 2025, Project PS1 /Army Long Range Persistent Surveillance (ALPS) was a new effort realigned within PE 0604820A / Radar Development. Funding realigned from PE 0604741A / Air Defense Command Control and Intelligence - Eng Dev, Project 126 /PEO Electronic Protect for the design, development, integration, and test of ALPS. 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.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
FY 2027 funds will support: - Continue building of prototype assets to be used for qualification and developmental testing - Validate Safety and Human System Integration designs - Begin Developmental testing - Participate in Transformation in Contact (TIC) activities
