The NORTHCOM online magazine, The Watch, reports,
“Arctic Edge, a multinational, multidomain exercise that began in February 2026 in Alaska and Greenland, made history in two ways. It is the first time Greenland was included in the annual exercise, which will conclude mid-March. It also is the first time that United States Northern Command (USNORTHCOM) organized the exercise after Greenland’s defense was transferred to USNORTHCOM from U.S. European Command last year. Canadian, Danish and U.S. forces are taking part in Arctic Edge, designed to highlight the military capabilities of the allies in an often inhospitable region…
“Arctic Edge will include NORAD and USNORTHCOM forces from Air Forces Northern, Army North, Naval Forces Northern, Marine Forces Northern, Special Operations Command North, Alaskan NORAD Region, Canadian NORAD Region, Alaska Command, and the Continental U.S. NORAD Region. Also participating are the Alaska National Guard and interagency partners including the FBI, U.S. Coast Guard, National Oceanic and Atmospheric Administration, the Federal Aviation Administration and Alaska state and local law enforcement, the release stated.”
No the “U. S. Coast Guard” was not in bold on the original. I did that. Hopefully, since the exercise is probably over, we will hear what the Coast Guard did in this exercise. Normally I would expect one cutter, could there be more. How about Coast guard aircraft? C-130s, Air Station Kodiak? the new FRCs?

Does the USCG have Arctic capable and qualified vessels? Which USCG vessels are Ice-hardened? How extensive is the introduction of The Mobile User Objective System (MUOS) SATCOM?
There are the three icebreakers of course, Polar Star, Healy, and Storis. In addition there are
16 WLBs, 225 foot Juniper class buoy tenders. https://en.wikipedia.org/wiki/USCG_seagoing_buoy_tender#225'_–_Juniper-class_ships
14 WLMs, 175 foot Keeper class buoy tenders. https://en.wikipedia.org/wiki/Keeper-class_cutter
9 WTGB, 140 foot Bay class icebreaking tugs. https://en.wikipedia.org/wiki/Bay-class_tugboat
11 WYTL, 65 foot tugs. https://en.wikipedia.org/wiki/USCG_65%27_Small_harbor_tug
I don’t have anything about Mobile User Objective System (MUOS) SATCOM.
Ice hardened hulls are the first requirement in naval vessels that will be exposed to Annual Ice in the Arctic. That ice can form overnight, but the meter thickness comes with time. We do not build Surface Combatants with Ice hardened hulls.
Also cutters that are not ice strengthened do go into the Arctic. National Security cutters have gone North of the Bering Strait and WMEC270s regularly exercise with the Danes and Canadians.
I’m familiar. They have superior weather forecasting over what we have had in the past.
I have been very interested in the ice strengthened corvettes the Finns are building.
