Sea-based missile defense is vital to our overall ability to defend ourselves, but it is not a substitute for the land-based system which is designed to provide defense against longer range ballistic missiles.
Absent Soviet agreement to such a ban (like the one that ultimately emerged in the INF Treaty with respect to medium-range ballistic missiles), any reductions agreed to in START could be readily circumvented without detection.
"But our concerns with Iran's development of space launch vehicle technologies are obviously well-known: Any space launch vehicle capable of placing an object in orbit is directly relevant to the development of long-range ballistic missiles, " she told reporters.
Substantial Foreign Interest in Defenses: It is these threats, and the advantages of space-based defenses to ameliorate them, that have caught the attention of the Western European Union, whose member countries are already exposed to short- as well as longer-range ballistic missile threats.
The report, which was signed by U.S. Defense Secretary Leon Panetta and sent to senators and U.S. representatives on defense committees, said Iran is continuing to develop other missiles that can hit Israel and Eastern Europe, including an extended-range Shabab-3 and a medium-range ballistic missile called the Ashura that can fly more than 1, 200 miles.
