Description
The system consists of ground-based interceptor missiles and radar which would intercept incoming warheads in space. Boeing Defense, Space & Security is the Prime Contractor of the program, tasked to oversee and integrate systems from other major defense sub-contractors, such as Computer Sciences Corporation. The key systems of the GMD system are:
- Exoatmospheric Kill Vehicle (EKV) — Raytheon
- Ground Based Interceptor (GBI) — Orbital Sciences; for every interceptor missile there is a missile silo and a Silo Interface Vault (SIV), which is an underground electronics room adjacent to the silo.
- Battle Management Command, Control and Communications (BMC3) — Northrop Grumman
- Ground Based Radars (GBR) — Raytheon
- Upgraded Early Warning Radars (UEWR) (aka PAVE PAWS) — Raytheon
- Forward Based X-Band Radars (FBXB) such as the Sea based X band platform — Raytheon
Interceptor sites are at Fort Greely, Alaska and Vandenberg Air Force Base, California; a third site was planned for a proposed US missile defense complex in Poland, but was canceled in September 2009. A description of the program can be found in the Missile Defense Agency Budget Item Justification document, dated February 2007.
In December 2008, the US Missile Defense Agency awarded Boeing a $397.9 million contract to continue development of the program.

Famous quotes containing the word description:
“I fancy it must be the quantity of animal food eaten by the English which renders their character insusceptible of civilisation. I suspect it is in their kitchens and not in their churches that their reformation must be worked, and that Missionaries of that description from [France] would avail more than those who should endeavor to tame them by precepts of religion or philosophy.”
—Thomas Jefferson (1743–1826)
“God damnit, why must all those journalists be such sticklers for detail? Why, they’d hold you to an accurate description of the first time you ever made love, expecting you to remember the color of the room and the shape of the windows.”
—Lyndon Baines Johnson (1908–1973)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
