Operation Crossroads
In July and August 1946, Kirtland Field and Sandia Base personnel took part in Operation Crossroads at the Eniwetok Proving Ground in the Pacific's Marshall Islands. Operation Crossroads was the first of many atmospheric nuclear weapons tests in the early Cold War years. The Kirtland Field Narrative Histories do not make specific reference to participation in Operation Crossroads by groups at Kirtland Field, but this is most likely due to the high security that the operation garnered.
