US Navy construction divers recently held a training exercise in Estonia where they practiced underwater blasting beneath ice, marking the first time they have conducted such drills. The goal was to learn how to use explosives to remove obstacles that may block ships' access to ports. This exercise is particularly relevant given the growing emphasis on the Arctic region and the need to be prepared for various operational scenarios.

During the training, the divers attached explosives to a rail that was submerged under the water, allowing them to observe the effects of the shockwave generated by the blasting under ice. Chief Officer Tim Dailey, who has 20 years of experience, emphasized the importance of being ready for any type of environment they might encounter, stating that it is crucial to practice these skills even in icy conditions.

The exercises also reflect the increasing military focus on the Arctic, as geopolitical interests in this region rise. The capability to perform underwater demolition in such challenging conditions can have significant implications for naval operations in Arctic waters as the region continues to undergo strategic changes due to climate change and international interests.
