Budget Trajectory
The program's 3 summary figures for FY24 to FY26, plotted in fiscal-year order so the direction of travel is readable at a glance: this line ends level with where it starts. The points are the summary cards above, not a separate derivation; the table beside the chart carries each figure with its own citation.

10 fiscal years of this program as published (FY2016–FY2025): a line through the actuals (filled dots), with the enacted (hollow circles) and request (diamonds) markers each edition reported. Read it for direction, not for precision — this program's actuals line rises across the span, and 4 years are a break in the line rather than a low value: an edition the program is absent from, never interpolated. The grid below is the same data as text, one cited figure per cell.

The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Decade series values by fiscal year and President's Budget edition: one row per series (actuals, enacted, request), one column per fiscal year. Every figure opens its own citation.

blank = series not published for this year; – = absent from that edition.

Asked vs spent: the PB2018 book requested $25.0M for FY2018; the PB2020 book reported $24.1M as actual total obligation authority — $868.0K below the request. 24.125.0 = -0.9 USD millions — the compact figures above are rounded for reading.

Description

Mission CSAR EMD

The Combat Survivor Evader Locator (CSEL) System provides aircrews with end-to-end global satellite secure emergency communication capability during combat and peace-time flying operations. CSEL provides a hand held radio as part of the mandatory aircrew survival gear. CSEL is a joint program (Air Force, Army, Navy, and US Marine Corps) and is the DoD program of record for personnel recovery survival radios. CSEL supports four of five Personnel Mission Phases: Report, Locate, Support, and Recover. A National Security Agency (NSA) Cryptographic Modernization mandate and the Ultra High Frequency Follow-On satellite constellation are at the end of life and are driving upgrades to base stations. This effort includes development to modernize the system to integrate common waveforms, integrate broadcast reception for non-CSEL devices. A portable interrogator will precisely locate the IP using the CSEL architecture without extensive audio communications that could compromise both rescue forces and IP. The portable interrogator will enable communication between IP and any designated aircraft not equipped with a AN/ARS-6 PLS Lightweight Airborne Radio System (LARS) or similar device as a Rescue Support Force (F-35, F-16, F-15E, Ground Teams etc.) asset. This program element may include necessary civilian pay expenses required to manage, execute, and deliver CSEL capabilities. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605826F, 0605827F, 0605828F, 0605829F, 0605830F, 0605831F, 0605832F, 0605898F, and 0605833F. In FY 2024, $0.000M was expended for civilian pay expenses in this program element and in FY 2025 $0.000M is forecasted for civilian pay expenses in this program element. This program is in Budget Activity 5, System Development and Demonstration (SDD) because it has passed Milestone B approval and is conducting engineering and manufacturing development tasks aimed at meeting validated requirements prior to full rate production.

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.

Oversight

Department-level designation (not specific to this program)

GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not Combat Survivor Evader Locator — no program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.

No research dossier for this program — dossiers cover 50 of 1,741 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
