Iran tested an updated version of its most potent missile today, a weapon that Iran claims can fly farther and faster that previous models and that can be deployed more quickly.
The elements of speed and rate of deployment would make the Sajjil 2 missile more difficult for Western forces to detect and destroy before it is launched and harder to track and knock down once it is in the air.
The missile, which is Iran's most advanced two-stage surface-to-surface weapon, can reach targets up to 1,200 miles away. That puts Israel and American bases in the region, as well as parts of Europe, within its reach.
