Bloodhound 300, Bloodhound 701, 401 and 442 wkg Surveillance on 8000 kHz USB this past Monday (2/21) coordinating vessel movements within a hazard area for a missile test off the coast of Southern California. The Arrow 2 missile defense system test is a joint exercise between the United States and Israel that intercepted and destroyed a simulated Iranian ballistic missile threat.
Around sunset the stations switched over to frequency 2781.5 kHz USB for the remainder of the exercise. It was definitely an exciting event to monitor!
