How NATO Defends Against Emerging EMSO Threats

In this episode of From the Crows’ Nest, Ken Miller is joined by Mike Alperi, Deputy Program Manager of PMS 408 Expeditionary Missions Program Office at the Naval Sea Systems Command, to talk about his involvement in NATO Subgroup One and its cross-country collaborative Thor’s Hammer exercise — an initiative that allows systems from different nations to be tested side-by-side against cutting edge UAS and IED threats. Alperi says the annual four-week program has greatly expanded over the last decade, growing from five participating nations in 2015 to 14 countries last year. Crucially, he says the scope of Thor’s Hammer has grown over the years, from just counter-ID and counter-UAS training to countering emerging small radio frequency threats. Alperi says the subgroup shares the information from these tests with participating countries around the world, making sure key allies have the best information available as EW technologies continue to rapidly evolve.
