Quoting from http://www.astronautix.com/craft/polyus.htm
"Polyus's failure to achieve working orbit was caused by a faulty inertial guidance sensor. ... The US Navy has made no statements about any attempts to investigate the wreckage of Polyus, which lies on the floor of the South Pacific."
"Scythian" ... such a pleasant name for a weapon.
Not for this specific item maybe =o)
