The crew of a Royal Australian Air Power P-8A Poseidon maritime patrol and anti-submarine warfare plane shared their experiences monitoring a US Navy nuclear submarine and dropping coaching torpedoes on it off the coast of Hawaii final Wednesday.
The drill, a part of the massive multinational Train Rim of the Pacific (RIMPAC), was a uncommon alternative to check the aircraft’s patrol and reconnaissance capabilities towards a dwell goal, the plane’s crew mentioned, per a launch on the coaching.
The P-8A Poseidon, which succeeded the older P-3 Orion, often serves in a surveillance and deterrence function. Because it first entered service in 2013, it is turn into broadly thought of one of the most sophisticated maritime patrol aircraft out there, that includes varied technical capabilities for detecting and monitoring subs and ships. The anti-submarine warfare aircraft additionally possesses the flexibility to have interaction hostile vessels
The Australian P-8A was joined by a US Navy P-8A and an MQ-9A unmanned aerial car, which recorded the train, in keeping with a news release from US Third Fleet.

The submarine focused was the US Navy Los Angeles-class assault submarine USS Topeka (SSN 754). The nuclear submarine is the fourth improved Los Angeles-class vessel, that includes a extra sturdy hull that enables the warship to dive deeper than different unmodified vessels of its class.
To search out the sub, the Poseidon started with vary surveillance, “basically flying a grid search sample at low altitude to seek out the precise location of the submarine,” the discharge mentioned. Within the train, the P-8s got the broad coordinates for the submarine’s location, however the crew needed to independently “set up natural monitoring and assault standards,” third Fleet mentioned.
The P-8 turned to its sonobuoys to map the sub’s movements. These are acoustic sensors used to seek out submarines. A float with a radio transmitter stays on the floor whereas a hydrophone is submerged for detection.

“We dropped sonobuoys to find out the observe of the submarine,” No. 11 Squadron Commander and Tactical Coordinator, Squadron Chief Tristan Hull, defined.
Hull added that “as soon as we had been in a position to set up place, course, and velocity of the submarine we had been in a position to derive an answer that met our assault standards and acceptable weapon placement to make sure most success.”
After finding the Topeka, the Australian sub-hunter dropped 4 Mark 54 train torpedoes. Hull described it as an in depth course of involving the sonobuoys being positioned appropriately within the space, the acoustics operator precisely deciphering the data to find the sub, after which the P-8A pilot flying over the goal in time.
It was the primary time an Australian P-8A dropped this variant of the Mark 54 Light-weight Train Torpedo, the information launch famous.
The bigger RIMPAC exercise, throughout which this coaching occurred, is the world’s largest worldwide maritime train targeted on the Indo-Pacific area. This yr’s train, the twenty ninth iteration, included individuals from throughout the area and past.

Monitoring, detecting, and interesting submarines in workout routines equivalent to this one helps practice plane crewa to higher perceive how to identify the various acoustic elements of a sub and the way they differ from the suggestions and noise of the encompassing ocean.
Maritime patrol plane crews routinely observe submarines outdoors of structured workout routines. Doing so can present useful intelligence in regards to the undersea capabilities of potential foes. Lately, an anti-submarine warfare aircraft belonging to a NATO ally followed a Russian submarine in the Baltic Sea, and earlier than that, a US aircraft stored tabs on one other Russian sub earlier than it docked off the coast of Cuba.
