ENSCO supports critical range safety systems at the United States Air Force’s (USAF) Eastern and Western Ranges, at the Alaska Aerospace Corporation (AAC) Kodiak Launch Complex, and at sites around the world. Our engineers architect, build, test, and participate in range operations, specializing in launch range modernization efforts.


ENSCO engineers are intimately involved in the entire life cycle of numerous telemetry modernization projects. When the AAC needed to upgrade its capability at the Kodiak Launch Complex to support the increased telemetry requirements of complex Missile Defense Agency missions, they called ENSCO to perform the systems engineering and integration role, including requirements definition, design reviews, range integration support, and final system verification. ENSCO currently provides verification support for the USAF’s telemetry modernization program at the Eastern and Western ranges.


ENSCO plays an important role in the specification and evaluation of range radar used to track single or multiple objects. Eliminating or modernizing operational radar and determining the need for a technology refresh requires an in-depth knowledge and understanding of the operation, as well as of the installed equipment.


Optics are critical from both a safety and mission assurance standpoint. ENSCO technologists provide systems engineering, integration, test, and evaluation support to ensure range optical instrumentation meets the requirements and expectations of the safety and user communities. In support of the space shuttle return-to-flight program following the Columbia Shuttle tragedy, ENSCO developed an algorithm for NASA launch controllers that ensured at least three optic mounts had a clear line of site to the shuttle during the critical phases of the ascent. NASA stated this effort was crucial to the successful return of the space shuttle to operation.

Command Control/Destruct

Critical to terminating the flight of an errant missile or rocket is the command/destruct system; therefore, launch ranges demand a 99.95 percent reliability rate from their command systems. ENSCO understands the critical task that the command/destruct systems support and has provided command control and command destruct expertise to the ranges for more than 20 years, most recently the operational test program for the Kodiak Launch Complex command/destruct system.

Range Safety

The protection of life and property has always been the key tenet of launch range operations. No systems receive more scrutiny than the range safety systems. ENSCO has conducted independent evaluation of range safety systems for more than 20 years. Support includes software IV&V, algorithm analysis, independent operational test programs, design analysis, and range safety operator training. We support safety development and operations at a multitude of ranges, including the USAF Eastern and Western ranges, the Kodiak Launch Complex, the Reagan Test Site in Kwajalein, the Pacific Missile Range Facility, and the White Sands Missile Range.
