Product Development

Project 361 funds the development, integration and testing of the Intelligence Electronic Warfare Tactical Proficiency Trainer (IEWTPT). IEWTPT is a Non-System Training Device (NSTD) which supports home-station training by simulating and stimulating Military Intelligence (MI) and Electronic Warfare (EW) organic or surrogate equipment. It enables training of critical individual, crew, and collective MI tasks/skills and is the core of the U.S. Army Intelligence Center of Excellence (USAICoE) Military Intelligence (MI) holistic training strategy supporting mission command, targeting, and MI Soldier and multi-domain army readiness. IEWTPT provides a realistic simulation intelligence target environment for multi-intelligence disciplines such as All Source Analysis, Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), Open-Source Intelligence (OSINT), Human Intelligence (HUMINT), Geospatial Intelligence (GEOINT) and EW in support of multi-domain operations (MDO) training. IEWTPT provides training for analyst and system operators to exploit intelligence and EW data during training, just as they would in "Real World" operations. The IEWTPT Technical Control Cell (TCC) is composed of two components: the Lower Enclave (LE) which supports exercise planning and scenario development and drives the All Source and GEOINT (and emerging EW) training tasks and the Upper Enclave (UE) which supports all SIGINT related training and operates at the Top Secret / Sensitive Compartmented Information (TS/SCI) classification level. FY 2027 funding will support multi-intelligence and EW scenario development tools for critical task training in a simulation environment. Funding will support integration of intelligence/EW training capabilities into emerging constructive simulation and cloud-ready applications. Base funding will continue to support enterprise level business processes and services enabling IEWTPT to efficiently develop, operate, and secure capabilities in accordance with OSW Digital Engineering and Army Digital Transformations Strategies. Funding promotes software integration and synergies and efficiencies between training and testing of intelligence platform systems, promoting re-use of common assets and services for Army modernization and defense priorities.

FY2027 planned work IEWTPT will continue to support IS-CDD requirements for ISR and EW system training for multi-domain operations (MDO) in a large-scale, simulation environment. Funding will maintain current multi-intelligence and EW training capabilities to support mission command, targeting, soldier readiness in a realistic, simulated operational training environment; FY2027 resourcing will maintain the current friendly and threat sensor congested/contested threat environment. The program will maintain multi-intelligence/EW training linkages into the distributed/federated constructive simulation environment and will continue integration events with Next Generation Constructive (NGC) to support collective…

FY2026 to FY2027 change FY2027 funding decrease due to reduction testing of training solutions and integration with intelligence systems (Tactical Intelligence Targeting Access Node (TITAN) and Army Intelligence Data Platform (AIDP)) in support of multi-intelligence discipline training modernization and MI soldier readiness.

FY2026 plans — current year IEWTPT will continue to support Information Systems-Capabilities Development Document (IS-CDD) requirements and simulation interface capabilities for Intelligence, Surveillance, Reconnaissance (ISR) and EW platform system training to support home station intelligence training for multi-domain operations (MDO) in a large-scale, simulation environment. Funding will further develop and advance the Army Military Intelligence (MI) cloud-ready baseline for point of need training execution across all components (Active, Guard, Reserve). Funding will improve multi-intelligence and electronic warfare (EW) scenario development tools for greater representation of the congested-contested, operational…

Program detail

Mission & acquisition strategy

This PE funds the development of constructive and wargame simulations used to realistically train commanders and their battle staffs on today's complex battlefield conditions. Project 361, Intelligence Simulation Systems, funds the development of the Intelligence Electronic Warfare Tactical Proficiency Trainer (IEWTPT). IEWTPT is a Non-System Training Device (NSTD) which supports home-station training by simulating and stimulating Military Intelligence (MI) organic or surrogate equipment. It enables sustainment of critical individual and collective MI tasks/skills and is the core of the U.S.

The program is actively operating in the Software Acquisition Pathway (SWP) (Execution Phase) to rapidly build and release capabilities that align to Army G2 and Intelligence Center of Excellence (ICoE) priorities in support of soldier readiness and intelligence modernization training. The IEWTPT Increment 2 contract is providing multi-intelligence and electronic warfare training support to combat training centers (CTCs) and home station sites. Funds support development, integration and testing to rapidly and iteratively deliver software capabilities to the warfighter.
