What project 124 buys
Advanced Analysis and Capability Development (A2CD): Continues the execution of advanced analysis under the JLE initiative and development and use of an advanced hardware, software, and Top Secret/Sensitive Compartmented Information/Special Access Program (TS/SCI/SAP) network architecture to conduct fully informed analysis, experimentation, and process improvement to accelerate the Department’s capability development and fielding efforts. Effort focuses on two areas. 1. Joint Lethality Engineering (JLE) (formerly designated as Advanced Concept Development): Research and analysis efforts to solve specific critical military challenges and drive Department investment decisions that enhance the effectiveness of systems against adversarial threats. Activities span across all security levels, domains, and Service warfighting architectures. Additional classified information available upon request. (**FY 2026 only; in FY 2027 realigning to MDJO PE 0604791D8Z) 2. Joint Capability Development Environment (JCDE): Advanced Modeling and Simulation (M&S) Technology and Tool Development and Modeling and Simulation Big Play – have been consolidated into an effort entitled Joint Capability Development Environment (JCDE) to provide a more unified and efficient development approach, afforded by previous accomplishments; advances in fully informed, all domain modeling and simulation (M&S) capabilities; and improved analysis and experimentation methods. JCDE provides a hardware, software, and TS/SCI/SAP network architecture designed to accelerate the Department’s ability to conduct rapid capability development and fielding. The JCDE provides industry, the DoW, FFRDC/UARCs, and international partners access to advanced modeling and simulation (M&S) tools and a multi-level security (MLS) enabled data/knowledge repository to enable rigorous, rapid analysis and experimentation in support of capability development and military utility analysis and experimentation. The JCDE also includes a development environment that enables the continuous creation and improvement of advanced M&S tools and corresponding analysis/experimentation processes.

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. 1 of them 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.
• Increase the availability of tools and enhance the performance of the JCDE infrastructure to accommodate new users, expand secure connectivity, deploy to new government and industry sites, and meet growing data processing demands. • Expand the JCDE boundary by integrating with the High-Performance Computing Modernization Program…
Read the FY2027 plan →FY2027 planned work Starting in FY 2027, Joint Lethality Engineering (JLE) activity (previously Assault Breaker II (ABII)), will be realigned to Multi-Domain Joint Operations (MDJO) (PE 0604791D8Z).
