ARA Offering Fundamentals of Low Observable Technologies Short Course Online


Applied Research Associates, Inc. (ARA) is excited to announce a virtual webinar continuing professional education short course called “Fundamentals of Low Observable Technologies” offered by ARA’s Berriehill Research Division (BRD) April 28-30.

The registration website is This multidisciplinary course is geared toward any scientist, engineer, and technician working with low observable (LO) ground, air, or naval systems, or any defense engineer looking for a broad exposure and understanding of LO technology. This course is especially relevant to newer engineers involved with designing, producing, flying, or maintaining LO vehicles, although any engineer will extract value out of this broad based professional short course.  

In the past, the 2.5 day course took place at TecEdge (Wright Brother’s Institute, 5000 Springfield St, Dayton, OH) and the lectures were augmented with an up-close focused tour of relevant aircraft displayed at the National Museum of the U.S. Air Force after the formal course material was presented. However, due to COVID-19, we are moving our educational experience online.

If you’re working from home and looking for some great continuing education, this is it -Brian Kent, event organizer and ARA chief scientist.

Note that the course will be only offered to US citizens, and we will vet students before providing course materials and the webinar connection information.

The unclassified teaching materials for the course draw upon decades of inputs from scientists and engineers who were involved with the development and fielding of LO systems. BRD, a preeminent leader in LO technologies, redeveloped legacy low observable course materials through the Ohio State University Defense Manufacturing Assistance Program (DMAP).  

There are 19 course segments, including Electromagnetic and Radar Fundamentals, Radar Cross Section (RCS) Basic Concepts, Radar Absorbing Material Overview, Acoustic Signatures, RCS Integration, comprehensive integration of LO concepts in air frame design, and more. Registration is open to Department of Defense government employees and contractors who are U.S. citizens and citizenship will be verified upon registration.

Since this course is only open to US Citizens, please follow the registration website directions carefully to get enrolled. There will also be information for corporate/government training focal points to register multiple students.  If you have any difficulty reaching the ARA LO Course website, please contact Dr. Kent ( or Kari Sowder (  to arrange for fax or over-the-phone registration.

Course Venue:  The course will be offered online. We’ll provide meeting credentials upon successful completion of all course registration steps.  Tuition is $1,950/student.

Typical Course Participant: Any scientist/engineer/technician working with low observable ground, air, or naval systems, or any defense engineer looking for a broad exposure and understanding of low observable technology. This would be especially valuable to newer Department of Defense government/contractors working on low observable projects.
