Coast Guard, Navy collaborate on preparing for mines, security threats in Southeast Alaska–

Coast Guard Cutter John F. McCormick (WPC 1121) has news of something a bit unusual happening in Juneau, a Navy/Coast Guard mine countermeasures exercise.

Doing mine countermeasures in Alaska is not easy for the US Navy because basically, the only navy in Alaska is the US Coast Guard.

There are basically three kinds of mine countermeasures done by USN,

  • airborne with a helicopter pulling a sled,
  • ship based, increasingly done by surface and subsurface unmanned systems as a way to keep sailors out the minefields,
  • and by divers.

Formerly the mine countermeasures ships were highly specialized, but they are now moving to using LCSs which are based in either Mayport, FL or San Diego, CA. In either case it would take a long time for them to get to Alaska.

The Helicopters, divers, and unmanned systems can be flown there, but they will need support including work space, communications, and ground and water transportation. The divers and unmanned systems will require supporting craft unless the mining is done very close to shore. The less they have to bring the better. That is apparently where the Coast Guard comes in.

It sounds like this is all preliminary to a more complex exercise in 2020.

“…Juneau could be a location of drills in 2020. Along with Anchorage, Kodiak and Seward, Juneau is an option for having an exercise in the water where Coast Guard and Navy personnel have to go in and figure out how to remove mines…”

One of the activities was touring the Webber class John F. McCormick (WPC-1121). Presumably the WPC was brought up from its homeport, Ketchikan, specifically for this purpose. Perhaps they are already familiar with Coast Guard’s buoy tenders, but they could also be very useful in supporting diver and unmanned systems operations.

As for where the 2020 exercise should be done–Cook Inlet–since Anchorage is the only strategic port in Alaska. Exercise results would also probably be more universally applicable if it is done away from the facilities of the District headquarters in Juneau, which are not available elsewhere in Alaska..
