Military personnel from various Nato allied and partner nations have participated in the Robotic Experimentation and Prototyping exercise using Maritime Uncrewed Systems 2022 (REPMUS-22).

REPMUS-22, which commenced on 12 September, is being held in and around Troia Peninsula in Portugal. It will conclude on 22 September.

Led by Portugal, the exercise involves contributions from Nato Centres of Excellence, Nato Centre for Maritime Research and Experimentation, academia and industry partners.

It is being conducted to support Nato Maritime Uncrewed Systems Initiative (MUSI).

Introduced in 2018, MUSI aims to bolster the collective contribution of the alliance for the development of maritime unmanned systems. 

Under the latest activities, around 1,500 deployed personnel are working together to evaluate the capability of uncrewed systems to coordinate on/above/under the sea. 

Currently underway, REPMUS-22 involves the integration of 120 autonomous assets into a single network, which will act as a testbed for different experiments and tests.

Nato Defence Investment Division Armament and Aerospace Capabilities director Dr Giorgio Cioni said: “This is the first time that so many Nato nations have the opportunity to test the effectiveness of so many systems, concepts, techniques and procedures related to MUS, ensuring they can work seamlessly together.”

Once REPMUS 22 concludes, the participants will undertake a new maritime exercise Dynamic Messenger 22, being conducted between 23 and 30 September.

Being held in the same area, the exercise will test the alliance’s capabilities to use uncrewed systems for countering submarine threats, sea mines and other asymmetric adversities.

It is being held under the joint leadership of Nato’s Allied Command Transformation in the US and Nato’s Allied Maritime Command, Northwood, UK.

Nato’s Standing Naval Maritime Group 1 and Standing Nato Maritime Counter Measures Group 1 will participate in Dynamic Messenger 22.
