Description

Mission Training System Aircraft

This program element provides for design, development, integration and test of various pre and post production platform improvements for Naval Undergraduate Flight Training Systems which include T-45, T-6, T-44, TH-57, TH-73A, T-54, and T-45 Follow-On: Undergraduate Jet Training System (UJTS). Continued development engineering for improvements in reliability, maintainability, and safety are required to ensure maximum benefit is achieved to provide effective cost of ownership and availability of aircraft to meet Chief of Naval Air Training (CNATRA) student training requirements. Specific efforts include: T-45, T-6, TH-57, T-44, T-54, and TH-73A Training System Improvements such as development and sustainment engineering change proposals (ECPs), avionics reliability and modernization, corrosion prevention ECPs, obsolescence ECPs, T-45 Retrofit Integration Testing (RIT), and new solutions required to meet evolving fleet training requirements; T-45 and T-6 Physiological Episode (PE) mitigation analysis; New Start T-6B Avionics Modernization; and T-45 Follow-On UJTS development. This program is funded under SYSTEM DEVELOPMENT AND DEMONSTRATION because it includes those projects conducting engineering and manufacturing development tasks aimed at meeting validated requirements prior to full-rate production decision.

Mission Physiological Episodes

T-45 and T-6 Physiological Episode (PE) Mitigation: Efforts will provide for studies and development efforts to address mitigation of the T-45 and T-6 physiological episodes.

Mission Training Aircraft Updates

Training System Improvements: Funding provides for design, development, integration and test of various pre and post production platform improvements including Retrofit Integration Testing (RIT) for Naval Undergraduate Flight Training Systems which include T-45, T-6, T-44, TH-57, TH-73A, T-54, and T-45 Follow-On UJTS. T-45 Follow-On: Undergraduate Jet Training System (UJTS): The T-45 Training System consists of the T-45C aircraft, ground-based training devices, curricula, and associated equipment. The T-45 is facing significant aircraft, engine, and component obsolescence issues. These issues are projected to dramatically increase operating costs and aircraft availability by 2030. This research and development effort will investigate alternatives for replacing the T-45 training system and develop and validate the acquisition strategy for the procurement of a new platform for the UJTS. The T-45 Follow-On UJTS will ensure training commands continue to provide the fleet replacement squadrons with qualified and capable naval aviators. This effort includes, but is not limited to, market research, requirements and training curricula development, evaluation of acquisition strategies, evaluation of proposals, development and testing of new training technologies, and testing of aircraft, Ground Based Training System, and equipment prototypes. New Start T-6B Avionics Modernization: Funding provided for the research and development for T-6B avionics system upgrades required to meet future Chief of Naval Air Training (CNATRA) operational requirements by mitigating issues associated with obsolescence, safety, and operational limitations.
