Russia maintains readiness to resume explosive nuclear testing at its Novaya Zemlya site following its 2023 de-ratification of the Comprehensive Nuclear-Test-Ban Treaty, with officials stating the facility is fully prepared for full-scale activities. Recent developments include a failed attempt in mid-September 2026 to test the nuclear-powered Poseidon torpedo system, attributed to technical issues amid sanctions, as well as canceled or completed missile launches such as Avangard and Yars systems during strategic exercises. These non-explosive delivery tests occur against the backdrop of heightened nuclear force modernization, increased deployed warheads, and mutual accusations with the United States over low-yield activities, though Russia has reaffirmed adherence to the testing moratorium unless Washington resumes tests first. The approaching Arctic freeze and diplomatic signals around Ukraine further shape the near-term environment for any potential shift.
