Some of the Navy units that the Coast Guard most commonly works with are being reorganized.
The Ports, Waterways, and Coastal Security (PWCS) mission the Coast Guard does in the US, when required outside the US, is a Navy responsibility, although they frequently seek Coast Guard assistance.
The Navy has decided to reorganize the way they do this mission, by combining at least to some extent, the organizations that do river and coastal missions.
They are also getting some new platforms to allow them to operate further from shore, including the new 85 foot patrol boat we talked about earlier.
There isn’t an exact correspondence between the way the Coast Guard defines the PWCS mission and the mission set for this new organization, but there are a lot of similarities and we can expect that there will be opportunities to train and exercise together.

“The Ports, Waterways, and Coastal Security (PWCS) mission the Coast Guard does in the US, when required outside the US, is a Navy responsibility, although they frequently seek Coast Guard assistance.”
In Vietnam Ports and Waterways was an Army mission. Is the navy grabbing this one too. In a recent Proceeding article about rethinking “Naval” mentions the Coast Guard just twice–briefly. The navy has never considered the Coast Guard naval. In fact, they have define “naval” in Title 10 and the Coast Guard is not included.
The new boats are just more ‘shoot and scoot.’ The navy has not learned that patrol work is slow work. The Coast Guard should have all the coastal and riverine work. It’s in the genes.
Bill, I agree with you completely. We are the best littoral sailors in the world, and traditionally we held this mission from our inception all the way to WWII. This is a more recent turn of events, with the USN trying to keep in these non-conventional wars.
