90 %.

With the subject of a missile malfunction in mind consider this amazing stuff.

From the Global Security.org Internet web site and the article "Hyunmoo - - Nike Hercules"

A very percentage of South Korean [ROK] surface-air-missile [SAM] the reliability in question to a remarkable degree!!

"The Air Force [South Korean] decided in 2001 to examine its Nike Hercules surface-to-air missiles, which had been deployed in the country since 1965. The scrutiny was conducted jointly with the state-run Agency for Defense Development and private LG Innotek. The measure came after ADD's report that more than 90 percent of Nike middle-range missiles were unable to fire warheads in recent tests. Only eight out of 100 Nike Hercules missiles had succeeded in launching their warheads during a reliability test three years earlier, while only 19 were able to shoot up first-stage propellant motors."

Major malfunctions of this percentage totally unacceptable. Those solid-fuel rocket engines evidently having aged with chemical deterioration of the solid-fuel engines and having a "shelf-life" far less than anticipated?

ACTUALLY HAVING THESE WEAPONS AS INVENTORIED FOR DECADES IT PERHAPS IS NOT SO SURPRISING THAT MANY OF THE MISSILES WOULD HAVE BEEN FOUND TO BE DUDS?
