Canadian, U.S. Submarine Participate in Torpedo Exercise

GROTON, Conn. - Canadian Navy Victoria-class long-range patrol submarine HMCS Corner Brook (SSK 878) returned to Canada after participating in a torpedo exercise with Los Angeles-class attack submarine USS Memphis (SSN 691) and Arleigh Burke-class destroyer USS Mason (DDG 87) in late August.

The exercise was held in the Cape Cod operating area and included the firing of 15 Mk48 ADCAP torpedoes and 6 Mk54 torpedoes.  This is the first time Victoria-class submarines have been used as targets in exercise torpedo firings. 

"Being on the receiving end of more than 20 torpedoes is not a natural state for a submariner," said Lt. Cmdr. Alex Kooiman, Corner Brook's Commanding officer.

"However, being able to practice a variety of evasive maneuvers numerous times during this exercise will give us a tactical advantage in the future."

The exercise was an opportunity for both submarine forces to continue to improve their ability to work together.

"Experiencing the different submarines is an important part of the Navy's working relationship with international partners. They help to enhance friendly, mutual cooperation and understanding between participating navies by developing interoperability in naval operations," said Cmdr. Charles Maher, Memphis' Commanding Officer.

Prior to the exercise, Corner Brook visited Naval Submarine Base New London for a five-day port call.  Submarine Development Squadron 12 was the host squadron.  Corner Brook last visited Groton in May 2009.

HMCS Corner Brook is 70.3 meters long, 7.6 meters across the beam and has a deep diving depth in excess of 200 meters.  HMCS Corner Brook has six torpedo tubes and can carry up to eighteen Mark 48 Mod 4 heavyweight torpedoes for use against surface and sub-surface targets. 

Memphis was built by Newport News Shipbuilding and Drydock Company. 

Commissioned Dec. 17, 1977, Memphis, a Los Angeles class attack submarine has multifaceted missions. It uses stealth, persistence, agility and firepower to deploy and support special force operations, disrupt and destroy an adversary's military and economic operations at sea, provide early strike from close proximity, and ensure undersea superiority.
