Fundamentals of Low Observable Technologies - Short Course WEBINAR!

8-10 December  2020 – Sign up today
for this 2.5 day live webinar course!

COVID19 has you down? – Here’s some on-line professional training just for you!

ARA’s BerrieHill Research Division is excited to offer this professional short course entitled “Fundamentals of Low Observable Technologies.” The unclassified teaching materials for this course draw upon decades of inputs from scientists and engineers who were involved with the development and fielding of LO systems. Previous versions of this course were taught within DoD from 1989 to 2006, and in 2016 The Ohio State University sponsored a significant revision and update to the course materials. In its present form, this professional short course will provide any engineer or scientist a multidisciplinary introduction and history of the development and fielding of Low Observable technologies. There are 19 course segments, including a review of Electromagnetic and radar fundamentals, Radar Cross Section (RCS) concepts, and absorbing materials properties and their measurements. The course also covers other observable signatures (infrared, visual, and acoustic), as well as a comprehensive integration of LO concepts in airframe design. The course culminates in a focused discussion of 6-8 relevant air vehicles using public materials from the  National Museum of the US Air Force. This course is especially relevant to newer engineers who must understand LO technologies if they are involved with designing, producing, flying, or maintaining LO vehicles. Click the link below for a course syllabus. The course materials are UNCLASSIFIED Distribution D and no classified materials will be provided.

Course Tuition:

$1,950.00 per student. Payments must be made by credit card ONLY through this website. In the event you experience trouble paying through our site, please contact Kari Sowder, 937-999-3124. ARA’s Course Refund Policy is found at the bottom of this page.

TO REGISTER FOR THIS COURSE (Please read completely)

There are THREE separate steps you must complete required to register for this course: Once all steps are complete, you will receive email verification that you are fully registered. You will also receive an email as you complete each individual step.

Administrative Registration: Download the registration PDF form, fill it out completely, and either FAX it to (937)-435-1018 attention Brian Kent or email to

Payment: Payment can be made by credit card for any individuals, OR corporate training accounts can fund single or multiple registrations through this webpage. (If you are registering “n” separate students, please send a separate email to indicating the names of the “n” students.) The course Tuition is $1,950 per attendee. (ARA’s refund policy for the course is printed below the registration instruction.) To pay, simply “add to cart in the sidebar of this page” the number of course tuitions you are paying for, and complete the check-out process. Once registration is complete, you will receive a follow-up email that your order for the total tuition payment has been received and processed.

Proof of US Citizenship: You must submit proof of US Citizenship to attend. ARA will accept one of three methods for verifying US Citizenship which will fully protect your privacy. (i) If an attendee possesses a DOD clearance, they can pass a visit clearance to ARA using the JPAS (Joint Personnel Adjudication System). To pass the JPAS Clearance, indicate your POC (Dr. Brian Kent), Visit Purpose (LO Short Course December 8-10, 2020), Address (for clearance) 7735 Paragon Rd, Dayton, OH 45459 and ARA’s SMO Code is 31AR24. (ii) For attendees who do not possess a clearance, ARA must receive a letter of proof of employment and citizenship on your Company’s letterhead stating/certifying your date and place of birth or proper references to naturalization paperwork (if you were not born in the US). This letter should be signed, scanned, and either emailed to or faxed to (937)-435-1018. (iii) Alternately, if you possess a US passport, you can scan it into a PDF file and email it to ( If you choose this option, ARA strongly recommends password protecting the scanned PDF file of the passport, and calling Dr. Kent separately (937-572-3025) to pass on the password by phone.) Your passport file will be deleted once citizenship is verified.

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 DoD government/contractors working on low observable projects.

Course Cancellation and Refund Policy:

Full tuition refunds will be issued if cancelled before 5PM Monday November 30, 2020. Between December 1-7, 2020, the course registration can be transferred with written permission of the student’s employer to any other participant at no cost as long as the new student is a government/contractor and U.S. citizen. Sorry, there will be no cash refunds after Novemver 30, 2020.

To receive a refund, you must email your request to You must provide your online order number in order for the refund to be issued. A refund will be sent to the credit card used to make the purchase. ARA will reply to your refund request email when the refund is issued. It may take 7-10 business days before the credit appears on your card. You will need to contact your credit card company if the credit has not appeared after this time.

In the very unlikely event the course does not enroll a minimum of 18 students, ARA reserves the right to cancel or reschedule the offering, and ALL students will be afforded full refunds.
