Constructive Simulation Systems Development

The Constructive Simulation Systems Development program (PE 0604742A) is a key Army research, development, test, and evaluation (RDT&E) initiative focused on advancing simulation and wargaming capabilities to train commanders and their staffs for complex, modern battlefield conditions. The program is divided into two primary projects: Intelligence Simulation Systems (Project 361) and Joint Land Component Constructive Training Capability (JLCCTC) (Project 362). Each project addresses specific training needs and modernization objectives, with funding allocated to software development, integration, and the implementation of advanced simulation environments.

Intelligence Simulation Systems (Project 361) is centered on the development, integration, and testing of the Intelligence Electronic Warfare Tactical Proficiency Trainer (IEWTPT). This Non-System Training Device (NSTD) provides home-station training by simulating and stimulating Military Intelligence (MI) and Electronic Warfare (EW) equipment. The primary goal is to enable the sustainment and advancement of critical MI tasks and skills, supporting the U.S. Army Intelligence Center of Excellence's holistic training strategy. IEWTPT delivers realistic simulation environments for multiple intelligence disciplines, including All Source Analysis, Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), Open-Source Intelligence (OSINT), Human Intelligence (HUMINT), Geospatial Intelligence (GEOINT), and EW.

Objectives for Project 361 in FY 2026 include enhancing multi-intelligence and EW scenario development tools, improving threat modeling at theater and national levels, and integrating intelligence training capabilities into cloud-ready applications. The program also aims to establish enterprise-level business processes and services that align with the Office of the Secretary of Defense (OSD) Digital Engineering and Army Digital Transformation Strategies. Funding supports software integration, promotes synergies between training and testing, and encourages the reuse of common assets to support Army modernization priorities.

A significant technical aspect of IEWTPT is the Technical Control Cell (TCC), which consists of a Lower Enclave (LE) for exercise planning and scenario development, and an Upper Enclave (UE) for SIGINT training at the Top Secret/Sensitive Compartmented Information (TS/SCI) level. The program is leveraging the Software Acquisition Pathway to deliver iterative software capability releases that align with Army G2 and Intelligence Center of Excellence priorities. The Increment 2 contract with General Dynamics is focused on providing multi-intelligence and EW training support to both Combat Training Centers and home station sites.

Joint Land Component Constructive Training Capability (JLCCTC) (Project 362) is designed to support Army Title X training for commanders and their staffs at Mission Training Complexes, Training and Doctrine Command (TRADOC) facilities, and other customer locations worldwide. JLCCTC provides a composable federation of software models and simulations to train units in offensive, defensive, stability, and civil support operations. The system delivers appropriate levels of modeling and simulation fidelity to support collective and combined arms training, and is configurable to meet the intent of specific training exercises.

JLCCTC has focused on improving software models to comply with emerging Common Operating Environment (COE) and Computing Environment (CE) requirements, enhancing Mission Command stimulation, and meeting cybersecurity standards under the Risk Management Framework (RMF). Additional objectives include evolving the system to support concurrency in commander and staff training from brigade through theater level, conducting government system test and evaluation, and developing constructive terrain and tools for integration with the Next Generation Constructive (NGC) environment. In FY 2026, funding for JLCCTC RDT&E efforts is suspended per Army direction, with resources reprioritized to accelerate Synthetic Training Environment Software Next Generation Combat capability.

The acquisition strategy for JLCCTC involves a contract with Phoenix Logistics Inc., which provides software modifications for cyber compliance, maintains cybersecurity posture, and ensures fielding of major software releases to 46 sites worldwide. The program's efforts are now limited to cyber hardening, configuration management, and limited helpdesk activities, in line with Army leadership's direction to sustain and secure the current version of JLCCTC while transitioning to future training environments.
