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.
● actuals (line) · ○ enacted · ◇ request — gaps are editions the program is absent from, never interpolated.

Asked vs spent: the PB2024 book requested $7.62M for FY2024; the PB2026 book reported $7.17M as actual total obligation authority — $447.0K below the request. 7.2 − 7.6 = -0.4 USD millions — the compact figures above are rounded for reading.

Description
Description — Heaters and ECU's
This budget line represents the Army's family of Improved Environmental Control Units (IECUs), commonly known as Air Conditioners. IECUs provide cooling and supplemental heating for Army tents and shelters. Systems range in size from 9,000 to 60,000 British Thermal Units/hour (BTU/hr) and are powered by common electrical currents supplied by both mobile electric power systems and standard commercial facilities. IECUs also provide dehumidification and filtering of air in support of environmentally sensitive electronic equipment in mobile shelters and vans. IECUs support critical electronic equipment that would not support the Army mission without proper environmental control. IECUs support numerous major tactical weapon systems. The majority of the supported weapon systems are command, control, and communication items. Other applications include medical facilities, expeditionary basing, support equipment, satellite communications, intelligence gathering systems, petroleum and water logistics laboratories, electronic shop sets, Test Measurement and Diagnostic Equipment (TMDE), aviation shop sets and topographic support sets. The IECU program will provide a new generation of Environmental Control Units (ECUs) that use environmentally approved refrigerants, with zero ozone-depleting chemicals (ODCs), to replace the current Military Standard (MIL-STD) Family of ECUs. IECUs are required to replace currently fielded environmental control units in order to comply with statutory and regulatory restrictions on the use of Class II Ozone Depleting Chemicals (ODCs) and to increase the performance of military ECUs. IECUs operate at wider operating temperatures, are more ruggedized than commercial ECUs, and employ embedded diagnostics and automatic safety controls. Technical improvements over existing military-standard ECUs will yield significant fuel and weight savings, reduction in scheduled maintenance, and increased reliability. 60,000 (3 phase / 50-60 hertz) BTUH (British Thermal Units per Hour) Army Acquisition Objective (AAO) = 3,630 9,000 (single phase / 60 hertz) BTUH AAO = 223 18,000 (3 phase / 60 hertz / 208V) BTUH AAO = 3,573 18,000 (single phase / 60 hertz / 230V) BTUH AAO= 440 36,000 (3 phase / 60 hertz) BTUH AAO= 874 Note: Requirement is to fill existing shortages or provide replacement for assets that are over age, non-supportable, and non-repairable. The IECUs are critical to the systems they support. Additionally, IECUs are required to fill urgent shortages on new fielding of high priority weapon systems. They are used in select shelters which house critical life-saving operations in Combat Support Hospitals and storage of perishable supplies in Brigade Support Battalions. The IECUs provide an EPA compliant capability to the force structure before commercial/military stocks of previously used refrigerant are exhausted and no longer available. IECUs provide essential air conditioning, dehumidification and filtering of air in support of environmentally sensitive electronic equipment in mobile shelters and vans critical to the CP mission and are a critical component of multiple mobile weapons systems. Present and emerging command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR) systems require environmental control to moderate the environmental temperatures in which these systems operate.
Justification
Justification — Heaters and ECU's
FY2026 base procurement dollars in the amount of $14.288 million supports the family of Improved Environmental Control Units (IECU) and Base requirements. Funding will support procurement of First Article production assets and an additional delivery order. FY2026 funding also continues to fund technical and logistics support documentation for 10 year IDIQ. In accordance with Section 1815 of the FY 2008 National Defense Authorization Act (P.L. 110-181), this item is necessary for use by the active and reserve components of the Armed Forces for homeland defense missions, domestic emergency responses, and providing military support to civil authorities.

Follow the dollar
No follow-the-dollar view — this program's awards haven't been crosswalked at high confidence (flows cover 312 of 1,938 programs). why coverage is partial? →
Awards
No awards are linked to this program element at high or medium 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 Heaters and ECU's. No program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
Program dossier
No research dossier for this program — dossiers cover 50 of 1,938 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
