## What project 645352 buys

The Department of Air Force (DAF) Portfolio Acquisition Executive (PAE) Command, Control, Communications and Battle Management (C3BM) combined the roles of the Chief Architect and the Chief Engineer into a single office called the Architecture and Systems Engineering (ASE). This office is responsible for the technical integrity of the DAF BATTLE NETWORK as efforts integrate Advanced Battle Management System (ABMS) capabilities, the rest of the DAF's C2 systems, and other Services' capabilities under Joint All-Domain Command and Control (JADC2). Architecture integration in system-of-systems mission threads and environments is critical to deliberately advancing the DAF's technological edge by informing architecture design, acquisition investments, system requirements for future capabilities, and acquisition baseline updates for current systems. The Operational Response Team (ORT) facilitates quick reaction prototyping and experimentation in response to warfighter-led efforts and new relevant technologies. Providing subject matter expertise to support prototyping and experimentation proposed architectures. Architecture Design and Evaluation and the ORT provide the subject matter expertise to develop mission-focused architectures to enable cross-cutting architecture development across PAEs, Major and Field Commands. Architecture Design and Evaluation analyzes science, technology, research, development, and experimentation enterprises to determine the technical and operational feasibility of new technical concepts Architecture Design and Evaluation is directed by the DAF PAE C3BM with oversight by the Secretary of the Air Force along with the Chief of Staff of the Air Force, Chief of Space Operations, and Senior Acquisition Executive. This activity is supported by the Air Force Research Laboratory. This program element may include necessary civilian pay expenses required to manage, execute, and deliver Department of the Air Force Tech Architecture. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F, 0605831F and/or 0604858F. In FY 2027, $8.503 million is budgeted in this program for 41 direct Full-Time Equivalent (FTE) civilians.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; Management Services.
