On April 3, 2015, the United States Government Accountability Office (GAO) released the report entitled “Space Acquisition: Space-based Infrared Systems Can Benefit from Technology Embedded Planning,” a total of 25 pages in total. REPORT BACKGROUND “Space-based Infrared Systems” (SBIRS) is an important part of the U.S. Department of Defense’s missile warning and defense system. In order to replace the first two satellites currently in orbit, the U.S. Air Force plans to manufacture two more satellites of the same design as the first satellites, the fifth and sixth geosynchronous satellites GEO-5 and GEO-6 of the SBIRS . The basic design of SBIRS has not changed for many years, some skills
