ATK produces [[Graphite-Epoxy Motor|Graphite Epoxy Motors]] (GEM) and largest composite fairings for the Delta II rocket as a subcontractor for the United Launch Alliance. As of June 2014, ATK has produced 987 solid rocket boosters for Delta II missions. These strap-on boosters, known as GEM-40s, add 434,000 pounds to the Delta II's maximum thrust. The GEM-40s can be used in groups of three, four, and nine depending on the weight of the payload. The composite structures supplied by ATK increase performance by reducing weight. In addition to composite booster cases for the GEM-40s, ATK produces a 10-foot wide composite payload fairing that covers and protects satellites during launch. ATK also produces the titanium diaphragm propellant tanks and pressurant tank for each Delta II vehicle.<ref name="Delta">{{cite web|url=http://www.standard.net/Business/2014/07/02/ATK-sets-record-with-latest-satellite-launch.html|title=ATK adds to record with latest satellite launch|author=Standard-Examiner|work=Standard-Examiner|access-date=June 12, 2015|archive-date=February 11, 2023|archive-url=https://web.archive.org/web/20230211193910/http://www.standard.net/Business/2014/07/02/ATK-sets-record-with-latest-satellite-launch.html|url-status=dead}}</ref>
