Standing NATO Mine Countermeasures Group One (SNMCMG1) successfully conducted a focused Historical Ordnance Disposal Operation (HODOPS) for the safety and security of the Baltic region, in particular, the Bay of Riga. Above: HNLMS Luymes, flagship to SNMCMG1, operating her Towed Side Scan Sonar to scan the seabed to classify contacts. This important information was over to the Belgium minehunter BNS Lobelia for identification and disposal.
Our teams worked through weather challenges and limited underwater visibility to get the job done
“This was a textbook example of real-world minehunting: detect, classify, identify, and dispose. Our teams worked through weather challenges and limited underwater visibility to get the job done,” Commander Kockx added.
TECHNOLOGY MEETS HISTORY
Using modern technologies, participating ships were able to compare current data with historical records, allowing for more precise identification and efficient clearance. Weather played an influential role: clearer weather conditions enhanced underwater visibility, improving detection and identification rates.
Throughout the HODOPS, ships received mission orders from the SNMCMG1 staff, which in turn maintained the operational overview, tasking individual units and managing reports to compile a complete picture of the minefield.
STRENGTHENING REGIONAL TIES IN RIGA
While in Riga, SNMCMG1 didn’t just focus on operations. The port visit included meetings with Latvia’s Minister of Defence, Andris Sprūds, and Flotilla Admiral Māris Polencs, Commander of the Latvian Navy. These engagements deepened professional ties and reaffirmed NATO’s commitment to regional security.
These kinds of port visits are more than a logistical necessity—they’re an opportunity to exchange ideas, deepen professional relationships, and reaffirm our shared commitment to maritime security

LONG-TERM IMPACT THROUGH SHARED INFORMATION
In addition to neutralizing ordnance, SNMCMG1 also shared updated seabed data and mine-related findings with Latvian authorities, contributing to long-term maritime safety. Besides UXO’s and remnants of historical mining activities, also two unrecorded wrecks were found and shared with the Latvian authorities.
When we find or destroy a mine, that information is immediately passed on to the relevant national authorities
“When we find or destroy a mine, that information is immediately passed on to the relevant national authorities. It’s not just about clearing the mines—it’s about raising awareness, improving safety, and maintaining open sea lanes for all.”
SNMCMG1’s cooperation in these operations highlights the strength of NATO´s interoperability and its unwavering focus on safe navigation, preparedness, and resilience across the Baltic region.
