### Project 674137 — Launch and Test Range System (LTRS) Modernization

System Delta 80 is developing and executing the Launch and Test Range System (LTRS) Modernization (aka Spacelift Range System) (Project 674157) for Guardians across Space Access, Command and Control, Operations, and Ops Commands. As a result, the Service will deliver space domain awareness capabilities, improve readiness and operational reach of existing force structure, deter, neutralize, defeat and/or destroy counterspace threats and defend the homeland, continue to advance all near term effects, and ensure resilient infrastructure, equipment, and personnel. The Spacelift Range System (SLRS), also known as the Launch and Test Range System (LTRS), provides public safety and assured access to space. LTRS operates at the Eastern Range (ER) at Patrick SFB/Cape Canaveral SFS, FL and the Western Range (WR) at Vandenberg SFB, CA. LTRS provides tracking, telemetry, communications, flight safety, and other capabilities to support launch of national security space (NSS), civil and commercial space payloads, Intercontinental and Sea Launched ballistic missile and missile defense evaluations, and aeronautical and guided weapon tests. LTRS ensures ability to meet the national launch requirement, safely supports the launch cadence of ER/WR launch requirement holders and provides assured access to space for the nation. The ER and WR are designated as Department of War Major Range and Test Facility Bases (MRTFB). To meet evolving technological requirements and Spaceport of the Future guidance, LTRS rebalanced funding from a predominantly Procurement focused appropriation to a balanced appropriation mix of Procurement and RDT&E funding through a Zero Baseline Transfer FY 2025 and beyond. This realignment of appropriations ensures requirements expend against the appropriation most suited for the type of development work required for mission fulfillment. No requirements planned for Procurement obligations were sacrificed to achieve this shift in funding profile, but a large subset of these requirements to modernize Range Instrumentation and associated services were moved to the software acquisition pathway effort as core capabilities. LTRS is comprised of 12 subsystems that together provide this capability to the ranges.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Delta-V | 26.2 | 25.9 | 36.0 |
| Enterprise Systems Engineering and Integration to Support Government-Controlled Baseline | 9.5 | 0.0 | 0.0 |
| LTRS Range Technology Integration | 8.2 | 28.4 | 20.8 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Government labs & warfare centers | 2.4% | 1.3 |
| Other / unspecified | 98% | 55.4 |

> R-3 exhibit contract funding, not USAspending obligations.

## Mission & acquisition strategy

System Delta 80 is developing and executing the Launch and Test Range System (LTRS) Modernization (aka Spacelift Range System) (Project 674157) for Guardians across Space Access, Command and Control, Operations, and Ops Commands. As a result, the Service will deliver space domain awareness capabilities, improve readiness and operational reach of existing force structure, deter, neutralize, defeat and/or destroy counterspace threats and defend the homeland, continue to advance all near term effects, and ensure resilient infrastructure, equipment, and personnel.

The Launch and Test Range System (LTRS) program acquisition strategy is Incremental System Modernization and Digital Transformation to ensure continued enablement of the accelerating National launch cadence executing on the Eastern Range (ER) and Western Range (WR). This strategy addresses the US Space Force (USSF) Spaceport of the Future (SOTF) objectives, formerly known as Range of the Future (ROTF), envisioned by Range instrumentation architecture—one of multiple SOTF lines of effort. The LTRS program is focused on developing a scalable system capable of responding to the demands of National Security Space objectives and DoW test and evaluation needs as well as assuring the Nation's ability to access space.
