The article focuses on the large infrared focal plane array (FPA) of the U.S. Missile Defense Agency's Multiple Kill Vehicle (MKV). This 512 X 512-pixel mercury cadmium telluride FPA is considered a linchpin for the success of Lockheed Martin's MKV-L design, requiring a central carrier vehicle that will deploy many smaller kill vehicles to attack targets in space. The Missile Defense Agency (MDA) recently enlisted Raytheon to develop a different, competing design for an MKV, assuring it will have options when the capability is needed.
