From The land-based SM3 could alleviate some of Russia’s concern on the third site due to range and placement of those sites. The system would first be placed in Israel and additional land-based SM3s will likely be placed in Turkey or the Balkan nations if an international agreement could be attained. The placement in Turkey and the Balkans could potentially have the ability to protect the U.S. homeland on early ascent intercepts of ballistic missiles from Iran.

An additional and new solution pursued and presented by the industrial complex this week was a mobilized, two-stage, ground-based missile interceptor designed for the third site in Poland so it can be placed where and when needed, not just restricted to the European region.

The issues of concern of both of these proposed solutions is the reality of the political loss and the international consequences of the U.S. withdrawing its commitment and bilateral agreements with Poland and the Czech Republic. The ramifications to those countries, Europe, NATO and Russia are significant and long lasting. Also of major concern is the capability to have “high” confidence in protecting the eastern United States seaboard particularly the southeast from long-range ballistic missiles from Iran. This capability of a look shoot look shoot confidence is not available from the current deployed GBIs in Alaska or California.
