"Several weeks ago, I had initially taken what I felt was appropriate administrative and corrective action involving Capt. Moses, based on the preliminary results of the investigation, which I began immediately after we recovered our sailors,” Donegan said in a statement.
"However, after thoroughly examining the findings of the final, comprehensive investigation, I determined that this additional action was necessary.”
Moses became the second senior Navy officer to be sacked over the incident. In May, Commander Eric Rasch, the executive officer of Riverine Squadron 3 at the time of the incident, was relieved of his post.
The Navy is also considering taking additional disciplinary action against seven other US crew members who, on January 12, wandered into Iranian territorial waters in the Persian Gulf.
Their fate will be announced next week, an AP source revealed. The seven include the now-fired squadron commander Rasch, his executive officer and three of the sailors.
At the time of the incident, Defense Secretary Ash Carter said the sailors made a navigational error that took them off course. The US position remained that riverine boats "planned transit path for the mission was down the middle of the Gulf and not through the territorial waters of any country other than Kuwait and Bahrain.”
