•  On page 12 of Arms Control Today’s October 2007 issue, the picture caption on page 12 reads, “A Ground-Based Interceptor is launched Sept. 2, 2006 from Vanderberg Air Force Base.” It should have read, “A Ground-Based Interceptor is launched Sept. 1, 2006, from Vandenberg Air Force Base.”

•  On page 22 of the same issue, a sentence describing Iran’s missiles begins, “The propulsion systems for Iran’s 1,300-2,000-kilometer-range Shahab-3 and 2,500-4,000-kilometer-range Ghadr and Shahab-3B missiles…” It should have said, “The propulsion systems for Iran’s 1,300-2,000-kilometer-range Shahab-3 and the up to 2,500-4,000-kilometer-range Ghadr and Shahab-3B missiles…”

•  The caption on page 23 identifies the Shahab-3 as a “long-range ballistic missile.” It should be identified as a “medium-range ballistic missile.”
