U.S. Coast Guard Cutter Kimball (WMSL 756) conducts a passing exercise with the Royal Canadian Navy ship HMCS Regina while Kimball patrols the Bering Sea, July 18, 2024. During Kimball’s 122-day patrol, the crew also interacted with strategic partners in Victoria, Canada, strengthening relationships by focusing on shared interests in the Bering Sea and the expanding Artic region.

The Indo-Pacific Defense Forum has a report on an exercise that indicates some degree of cooperation between the Coast Guard and the Air Force.
A key drill involved two B-52s simulating a long-range maritime strike. In a display of joint force precision, the bombers received targeting data from the U.S. Coast Guard cutter Kimball and U.S. Navy assets, allowing their crews to acquire targets from a significant distance and simulate a weapons engagement.

If we need NSCs to provide surface ship targeting data to then deploy some B-52s, we have bigger problems than I thought. This should be done by satellites. If a NSC identifies a surface ship that needs to be taken out, then let’s equip them with NSMs so they can do so themselves.
If we are talking at least the Air Force may not attack the cutter.
Satellite coverage over the Arctic is not nearly as good as it is over lower latitudes.
Point taken. I’d much prefer to just load up on NSMs and helo-delivered missiles. Quicker.
I figure this was just an opportunity to test targeting from a naval platform to the bomber.
Would an NSC survive long enough for a B-52 to get there if the target was important enough for a B-52 to be used against it?
Only case where that seems likely is if a Merchant vessel or large fishing vessel was being used to land special forces to destroy a radar station in the Aleutians at the start of a conflict. The cutter might not be able to destroy it.
At one point I advocated putting LRASM on large cutters to counter ships being used by terrorists to attack a US port, because I don’t think any US bases are ready to deal with the threat.
Recall if you may, this exercise may have led up to the decision to utilize the National Security Cutter (NSC) as the prime candidate for the Navy FF(X) program, the article doesn’t state the exact dates of the exercise, but the point being as stated here before, a ‘ninety-per cent’ solution and targeting platform. Whether it’s a B-52, E-6B, or AC-130, it’s a veritable platform, of the old “radar picket ship” .
That said, ‘Gee, I wonder if we could put an Air Search radar and EW suite on a Buoy Tender? ;0
Aboard the Active we coordinated with B-52s that were acting as our MPA during east-pac patrols back in 2016 and 2017. It was great because they could stay on station forever. They seemed to enjoy the cross training with us. As far as targeting… you really want to have networked systems that can talk to one another. I would not trust a bomber, no matter how proficient the crew was, to drop ordinance on a moving target using data from a cutterman who only had the Mk-1 eyeball, collision/weather radars, and voice comms. We had an OTH collide with a panga one night because the P-8 was giving us info almost two minutes behind what was actually happening. Panga was DIW and we were still telling the OTH coxswain they were doing 30+ knots. Thankfully no one was injured, but we didn’t even find out about the collision until the P-8 reported it. OTH crew was too busy managing the situation.
