Operation Eager Glacier was a secretU.S. effort to spy onIran with aircraft in 1987 and 1988.[1] The information gathered became part of an intelligence exchange between U.S. military intelligence services andIraq during theIran–Iraq War.[2]
Eager Glacier took place at the same time as other U.S. military operations in thePersian Gulf, includingOperation Earnest Will, the naval escort of Kuwaiti-ownedtankers;Operation Prime Chance, the secret attempt to prevent Iranian forces from attacking Gulf shipping; andOperation Praying Mantis, the retaliation for the mining of the U.S. guided-missile frigateUSS Samuel B. Roberts.
Years after, on 22 July 1992, formerchairman of the Joint Chiefs of StaffAdmiralWilliam J. Crowe testified to theHouse Armed Services Committee regarding charges that the Pentagon had concealed evidence about the 1988 downing of anIranian airliner by the U.S. Navy cruiserUSS Vincennes. As Crowe denied the coverup charges, he spoke briefly about Eager Glacier and other efforts to provide U.S. intelligence to Iraq. Crowe said that Pentagon officials had briefed "the pertinent congressional committees" about Eager Glacier on October 5, 6, and 13 October 1987. He also said, "Incidentally, in my judgment, these exchanges were not especially profitable."[3]
The bookNo Higher Honor mentions how intelligence between pilots nearly cost them their lives, and "For those who had somehow failed to get the picture," it's what signaled the end of the operation.[4]
