Submarines Add Extra Layer of Realism on Talisman Sabre 21

Beneath the impressive amphibious landings and multi-national fleet maneuvers lurked an unseen menace, keeping sailors on their toes during Ex Talisman Sabre 21 (TS21).

Royal Australian Navy submarines, HMAS Collins and HMAS Rankin, were on the prowl to disrupt surface-ship operations during a series of attack and interdiction missions. A United States submarine was also contributing to the sub-surface training scenario.

Unlike the submarine wolf packs of WWII, today’s subs are lone hunters; dodging sonar and other sensors looking for a torpedo shot.

Australian Navy Captain Peter Bartlett, TS21 Maritime Response Cell, said submarines were a very dangerous adversary when positioned well.

“It does not mean the submarine will always win. There are ways to defeat submarines through maneuvering and employment of air and surface assets,” he said.

As part of the opposing force for a portion of TS21, subs conducted sea-denial operations against the allied fleet, limiting their freedom of movement on the water’s surface.

This forced surface elements to undertake what Captain Bartlett referred to as the most complex type of maritime warfare – anti-submarine operations.

“That’s because of the environment and the capabilities of modern submarines,” Captain Bartlett said.

“Much of the training is based around the employment of fixed and rotary-wing aircraft, as well as surface ships.”

Captain Bartlett said anti-submarine warfare was something surface elements had to perform over extended periods to keep adversaries at bay, with difficulty varying based on a variety of conditions.

“It all depends on the environment and the water in which you operate,” Captain Bartlett said.

Submarines also conducted sub-vs-sub training.

The exercise included time to debrief the submarines’ teams after each serial and apply what they had learned.

“You cannot simulate the anti-submarine warfare training environment to the same extent without [other submarines],” Captain Bartlett said.

“You need a submarine with the thinking, reacting crew to train against.”
