Standing Nato Maritime Group One (SNMG1) is taking part in the latest maritime anti-submarine warfare interoperability exercise Dynamic Mongoose (DYMON).
DYMON 2019 is underway in the Norwegian Sea and across the Article Circle.
The exercise involves more than 2,000 military personnel from nine countries, including Canada, Denmark, France, Germany, Norway, Portugal, Turkey, the UK, and US.
It seeks to increase anti-submarine warfare (ASW) integration among the navies of Nato nations.
During the exercise, six surface ships, nine maritime patrol aircraft, and eight helicopters will train with four allied submarines in the North Atlantic.
SNMG1 joined the exercise after completing its participation in the multinational maritime-focused exercise BALTOPS in the Baltic Sea last month.
SNGM 1 Staff Chief of Operations chief operations specialist Juan Gutierrez said: “Exercises like Dynamic Mongoose give Nato allies an opportunity to train in a very challenging deep water/continental slope environment and a surface environment where seas can build from 5ft to 25ft or even 30ft in the matter of a couple days.
“This is not only unique for the creation of the exercise but challenging for the navies due to the unpredictable circumstances.”
The maritime task group comprises the US flagship guided-missile destroyer USS Gravely, British Royal Navy frigate HMS Westminster, and Turkish frigate TCG Gokova.
DYMON is designed to test the abilities of participating submarine hunting ships and submarines to work in partnership.
The third day of the exercise saw SNMG1 conduct a combined anti-submarine exercise (CASEX).
A CASEX scenario involves a group of ships and aircraft working together to search for submarines.
The submarine plays the opposing force and is required to perform simulated missions against the surface forces.
While the ships have both active and passive sonar, as well as radar and visual sensors, the helicopters are equipped with radar and visual detection systems to help detect the submarine.
SNMG1 staff anti-submarine warfare officer German lieutenant commander Ulrike Boelke-Dorr said: “We started the coordination for the Dynamic Mongoose CASEX’s about three months ago.
“With 27 units from nine countries participating, it’s important and beneficial for all navies to be assigned with their strengths of capabilities, which will provide crucial feedback for future missions.”
