Via the U.S. Coast Guard 17th District Alaska (emphasis mine):
The U.S. Coast Guard demonstrated its commitment to the Bering Sea and Arctic region with deployments of national security cutters Bertholf (WMSL-750), and Kimball (WMSL-756), and a U.S. Arctic patrol by icebreaker Healy.
“Security in the Bering Sea and the Arctic is homeland security,” said Vice Adm. Michael McAllister, commander Coast Guard Pacific Area. “The U.S. Coast Guard is continuously present in this important region to uphold American interests and protect U.S. economic prosperity.”
Crews interacted with local, national and international vessels throughout the Arctic. During the deployment, Bertholf and Kimball observed four ships from the People’s Liberation Army Navy (PLAN) operating as close as 46 miles off the Aleutian Island coast. While the ships were within the U.S. exclusive economic zone, they followed international laws and norms and at no point entered U.S. territorial waters.
The PLAN task force included a guided missile cruiser, a guided missile destroyer, a general intelligence vessel, and an auxiliary vessel. The Chinese vessels conducted military and surveillance operations during their deployment to the Bering Sea and North Pacific Ocean.
All interactions between the U.S. Coast Guard and PLAN were in accordance with international standards set forth in the Western Pacific Naval Symposium’s Code for Unplanned Encounters at Sea and Convention on the International Regulations for Preventing Collisions at Sea.
While the PLAN doesn’t “officially” have any cruisers, the brand new Type 55 DDGs (NATO designation Renhai-class) are big ships, running to 13,000-tons, and having a 112-vell VLS launcher installed with missiles cued by a phased array radar. In other words, a bigger, newer version of a Tico. They are the largest and most advanced Chinese surface combatant.
Facing off against this, the pair of 4,500-ton Legend-class National Security cutters combined had two 57mm Bofors, two CIWS, and some mounted machine guns.
In all seriousness, such interactions, coupled with the use by the Navy of the same class of white hulls to cruise through the contested South China Sea on Freedom of Navigation Patrols, point to the USCG’s larger cutters at a minimum getting an armament upgrade to swap out CIWS for C-RAM and pick up a few Naval Strike Missiles to at least put them on-par with the admittedly under-armed littoral combat ships.
If you act like a frigate, no matter the color of your hull, you better be able to back it up.
