“We were participating in the Royal Australian Navy’s Anti-Submarine Warfare exercise, acting as the fixed wing asset tasked with finding the enemy submarine,” Air Warfare Specialist Corporal Ryan Vincent said.

Also involved in the exercise were Royal Australian Navy vessels HMAS Hobart, HMAS Choules and four Anzac class frigates - Warramunga, Stuart, Toowoomba and Arunta - who at various times acted as either friendly or enemy forces for the submarine, HMAS Farncomb.

CPL Vincent is one of two acoustics operators on the P-8A, who interpret data from sonobuoys dropped from the aircraft into the ocean that the crew uses to track the submarine.

“We can also hear it as a ping, which does sound quite cool. We’ve got a couple of different sonobuoys, one of which sends out a signal and we hear a return ping when it’s acquired the target. It sounds like how you hear it in the movies.”

It was useful having our Australian allies close by to be able to have the opportunity to train with them and their capabilities, CPL Vincent said.

“There is a lot of flying in a live warfare scenario that you don't really get in the simulator, which is tightly controlled. In the real world, everything is a little bit more unpredictable, some things might fail, some things might be lost – you might be right on top of the contact, but not be able to hear it.

Internal communications were at a high tempo during the training, with information continually being passed to the Tactical Coordinator, CPL Vincent said.

“The exercise flying does get quite intense, but we are good at following our standard operating procedures. It’s quite high energy because contact with the target can be quite fleeting, so we need to make sure we're prepared and start tracking it when we need to.

“These targets are really good at evading us, but it’s good for our training,” he said.
