Officials say the US Navy is investigating alleged cheating on tests by senior enlisted sailors training on naval nuclear reactors.
The Naval Criminal Investigative Service is conducting the probe.
The allegations involve alleged cheating on tests related to the nuclear reactors that provide propulsion for Navy submarines and aircraft carriers. It does not involve naval nuclear weapons and thus is not comparable to the Air Force's investigation of alleged cheating by officers who operate land-based nuclear missiles.
The officials revealed the probe on condition of anonymity because it has not been publicly announced.
