While the Pentagon is calling this test a success, some experts cautioned that the $40 billion missile defense system still has a long way to go before it can be considered fully developed.
“It marks two successes in a row, which is significant, but only two hits out of the last five attempts; that is, only a 40% success rate since early 2010,” said Philip E. Coyle, a senior fellow at the Center for Arms Control and Non-Proliferation.
“In school, 40% isn’t a passing grade,” added Coyle, who formerly headed the Pentagon’s office of operational test and evaluation. “Based on its testing record, we cannot rely upon this missile defense program to protect the United States from a North Korean long-range missile.”
