As midnight approaches through the warship’s red-lit passageways and inside every busy berthing, the familiar anthem “We Ready” by Archie Evermore blares over the ship’s public address system or 1 Main Circuit (1MC). Capt. Tim Carter, commanding officer of the amphibious transport dock ship, USS San Diego (LPD-22), arrests the speaker system right on cue for his address. Meanwhile, choppy seas gift some sailors and Marines with glazed eyes, upset stomachs, and pounding headaches. Thankfully, the sea sickness is only temporary. Carter zealously declares to those onboard that the ship, its crew, and its embarked Marine Corps landing force is indeed ready for whatever may come as they transit the Indo-Pacific.
During the five-day training exercise, Marines operated a SEAB and conducted maritime operations from the island of Ukibaru, Okinawa. A SEAB is comprised of an active radar site and a passive sensor site. The passive site employs communication surveillance to detect and track potential adversary forces by analyzing electromagnetic frequencies and signal activity. Once an object is detected, the passive site will alert the active site to begin scanning, confirming, and identifying the object. When certain frequencies reflected are identified as adversary forces, this data is then communicated to the passive site in the form of targeting data.
