LANSING, Mich. -- The Naval Surface Warfare Center, Crane Division, based in Crane, Indiana is the lead agency for Silent Swarm 25, taking place July 14-25 at the Alpena Combat Readiness Training Center in Alpena. The exercise includes experimentation with technologies that can be employed on small multi-domain unmanned systems and may include surface vessels in the water and small unmanned airborne systems. The results from these experiments will improve spectrum maneuver and resilience capabilities for military personnel.
Additionally, personnel will work with tripod-mounted communications and radar equipment, all used to assess interoperability and performance of various communications and radar system configurations. Military radio frequencies involved in the testing will not interfere with radio or electronic communications in the area.
During this event, mariners can expect many small, unmanned surface, sub-surface and air vehicles in operation. Manned vessels will be in the vicinity for control and safety. If members of the public see vessels in the water or unmanned airborne systems, please do not attempt to approach, touch or interfere with them.
