Company s Fifth PTV Target Launch for the U.S. Air Force Space and Missile Systems Center Supports Readiness of Nation s PATRIOT System

DULLES, Va.Sep. 21, 2017-- Orbital ATK (NYSE:OA), a global leader in aerospace and defense technologies, successfully launched a PATRIOT Target Vehicle (PTV) for the U.S. Air Force Space and Missile Systems Center (SMC). Orbital ATK s PTV served as an intercept target for the U.S. Army Lower Tier Project Office (LTPO) PATRIOT air and missile defense system.

The PTV launched on September 17, 2017 from Wake Island into Reagan Test Site (RTS) Kwajalein Island. The target flew a southerly course over the western Pacific Ocean. The target and re-entry vehicle were designed, built and tested by Orbital ATK.

We are very pleased to support the Air Force and Army with a fifth successful target launch it flew its planned sequence precisely as expected, said Rich Straka, Vice President and General Manager of Orbital ATK s Launch Vehicles Division. We look forward to future tests with the PTV to continue supporting the readiness of the nation s PATRIOT system.

Orbital ATK has been supporting the U.S. Air Force with ballistic target systems for more than 20 years. The development of the Janus PTV target vehicle took just 19 months and included the development of a new re-entry vehicle. This development activity relied heavily on flight-proven designs from other Orbital ATK launch programs, such as the Medium Range Target, Targets and Critical Measurement Program, and Operational Test Two vehicle.
