The Defense Department has announced another package of security assistance for Ukraine, which will include additional High Mobility Artillery Rocket Systems (HIMARS), ammunition, and a substantial number of Phoenix Ghost unmanned aerial systems. This latest package includes about $175 million in equipment pulled from existing U.S. military stocks through presidential drawdown authority and $95 million…
The Defense Systems Information Analysis Center (DSIAC) was tasked with determining the extent of energetics additive manufacturing (AM) research and development capabilities in Europe. DSIAC searched available resources for any projects or research being performed by universities or defense organizations in Europe that involve the three-dimensional printing of energetic munitions, explosives, propellants, or rocket engines. There were a few organizations and universities that had…

This annual training event is a collaborative effort and draws information from threat exploitation, live fire testing, and combat experience to provide a complete picture of threat lethality.
The purpose of this recurring meeting is to provide model users, managers, stakeholders, and other interested individuals with the latest information regarding JASP-sponsored modeling and simulation (M&S) tools, as well as others, used by the aircraft survivability community to evaluate aircraft performance in realistic threat environments.
DSIAC is pleased to announce that the next Aircraft Combat Survivability Short Course will be held 2-4 June 2026 at Pratt & Whitney in East Hartford, CT. This three-day short course in aircraft combat survivability is designed to provide an overview of the aircraft combat survivability discipline. The course is intended for U.S. Department of…
Registration deadline for the High-Speed/Hypersonic (HSH) Subarea of the Air Platforms Community of Interest Technical Roadmap Interchange Meeting (TRIM) has been extended to March 10, 2026.
This four-day Military Standard 810 (MIL-STD 810) training focuses on the purpose of each test, the equipment required to perform each test, and the methodology to correctly apply the specified test environments. This class applies to ANY testing done to environmental test standards, including DO-160, IEC specifications, and all other documents that provide test methodology…
This three-day training in the fundamentals of random vibration and shock testing covers all the information required to plan, perform, and interpret the results of all types of dynamic testing. Some of the additional areas covered are fixture design, field data measurement and interpretation, evolution of test standards, and HALT/HASS processes. This class applies to…
