Military Marine

CTRL began working with the US Navy in the early 2000's. NAVSEA 04RM and the Maintenance Engineering Technology Team (METT) funded shipboard testing aboard the USS Gunston Hall in order to identify an inexpensive technology to significantly improve maintenance practices, reduction in man-hours, and improvement in fleet readiness.

Military Applications for Ultrasound Listening Devices (ULDs)

CTRL technology is being provided to military and other government organizations to meet the critical needs of readiness, improved man-hours, and evaluation of critical systems.

The performance and quality of CTRL's products have been proven and re-affirmed by NASA's selection of the UL101 ultrasound sensor for maintenance and leak detection on the International Space Station and all of the shuttles as well as several platforms by the U.S. military and prime contractors such as Lockheed Martin.


CTRL Systems, Inc. has been supplying its ultrasound technology to the US government, defense, and its allies for more than 20 years. As a result of CTRL's dedication to turnkey integration, the UL101 is a standard tool in many mission critical applications on platforms such as F-35, C-130, and F-18.
