Aegis Icebreakers?

More info on the new class of three planned Coast Guard Polar Security Cutters has bubbled up.

In short, they will be big boys, at 460-feet long and 33,000-tons. For reference, the Coast Guard’s current 50-year-old icebreaker, USCGC Polar Star (WAGB-10), is 399-feet long and weighs in at comparatively paltry 13,800-tons.

However, the Polar Sea is a bruiser, packing 75,000 shaft horsepower in her CODAG plant. This allows her to crush up to 21 feet of ice by backing and ramming and cruise through 6-feet of pack at a continuous 3 knots. According to a statement released this week, the new PSC’s will have 42,500 shp but will still meet an 8-foot mark on ice-busting.

Hmmm.

Of note, the Coast Guard’s single medium icebreaker, the 11,000-ton Healy can crack ice up to 10 feet thick.

More from VTH in Moss Point:

As you can see, the design is based on Finnish and German tech that is being used on the (under construction) German research breaker Polarstern II, which is about the same size.

The plan for Polarstern II is a good starting point as that ship includes:

-Maximum 130 persons on board.
-44 person crew living in single and double rooms.
-Normal cruises up to 60 scientists.
-Safety equipment (lifeboats) on each side 100%.
-80 places for 20” Containers (laboratories and storage).
-Seakeeping stabilizer suitable for the transit cruises and station operation.
-Helicopter Deck and Hangar for 2-3 Helicopters.

In short, these big breakers, larger than the planned German ship, could potentially carry a light company-sized landing force with a couple of helicopters.

Currently, the USCG’s cutters just carry a small arms locker with the capability to mount a couple of M2 .50-cals if absolutely needed. The penguins and polar bears have not put up much of a fight in recent years.

That could be changing.

Changes from the design to make the Coast Guard’s new vessel capable of fighting are still being decided. However, according to the USNI, “The ship’s combat system will be derived from the Aegis Combat System, and the Coast Guard is still mulling over the weapons loadout, [USCG Adm.] Schultz told reporters on Wednesday.”

In 2017, Coast Guard Commandant Paul Zukunft said the new icebreakers would be fully weaponized to include canister launched anti-ship missiles.

This was repeated in 2018 when he said:

“We need to look differently at what an icebreaker does… We need to reserve space, weight, and power if we need to strap a cruise missile package on it… U.S. presence in the Arctic is necessary for more than just power projection; it’s a matter of national security… If they remain unchecked, the Russians will extend their sphere of influence to over five million square miles of Arctic ice and water.”

Things could get interesting.

The country’s one-and-only polar icebreaker made it back home (barely)

Seattle saw the reappearance of “Building 10,” the common designation of the U.S. Coast Guard Cutter Polar Star (WAGB-10), as she returned this week to her homeport after an epic 105-day deployment to Antarctica in support of Operation Deep Freeze, the 63rd year for the annual mission to supply McMurdo Station in Antarctica.

This place:

Forget what you have heard about no more ice: Upon arrival in McMurdo Sound, Antarctica, Polar Star still had to break through 16.5 nautical miles of ice, six to ten feet thick, in order to open a channel to the pier for supply ships to follow.

As the vessel is 43-years-young and has seen lots of hard service (she rams icebergs on purpose) things did not go as planned along the 11,200-mile sortie.

From the Coast Guard:

During the transit to Antarctica, one of the ship’s electrical systems began to smoke, causing damage to wiring in an electrical switchboard, and one of the ship’s two evaporators used to make drinkable water failed. The electrical switchboard was repaired by the crew, and the ship’s evaporator was repaired after parts were received during a port call in Wellington, New Zealand.

The impact from ice operations ruptured the cutter’s centerline shaft seal, allowing water to flood into the ship. Ice breaking operations ceased so embarked Coast Guard and Navy Divers could enter the water to apply a patch outside the hull so Polar Star’s engineers could repair the seal from inside the ship. The engineers donned dry suits and diver’s gloves to enter the 30-degree water of the still slowly flooding bilge to effect the vital repairs. They used special tools fabricated onboard to fix the leaking shaft seal and resume ice breaking operations.

The Polar Star also experienced ship-wide power outages while breaking ice in McMurdo Sound. Crew members spent nine hours shutting down the ship’s power plant and rebooting the electrical system in order to remedy the outages.

On Feb. 10, the crew spent nearly two hours extinguishing a fire in the ship’s incinerator room while the ship was approximately 650-nautical-miles north of McMurdo Sound, Antarctica. The fire damaged the incinerator and some electrical wiring in the room was damaged by fire fighting water. There were no personnel injuries or damage to equipment outside the space. Repairs to the incinerator are already scheduled for Polar Star’s upcoming inport maintenance period.

Sheesh.

And keep in mind that for at least one pay period while underway the crew went without the eagle flying due to the lapse in appropriations.

The good news is, the Coast Guard is seeking to pick up six new polar icebreakers and the FY19 budget actually appropriated $655 million to begin construction of a new “polar security cutter” this year, with another $20 million appropriated for long-lead-time materials to build a second. So they may actually get two out of the planned six when all is said and done.

Hopefully, Polar Star can hold out till then.

Also, did I mention the Russians have 50 icebreakers?

Sad times on the icebreaking front

While the U.S. Navy ordered a class of 8 heavily-armed polar icebreakers in WWII (the Wind-class, which carried twin 5″/38 DP mounts, 40mm Bofors, 20mm Oerlikons, depth charges, seaplanes and an ASW mortar), as well as the larger single-vessel USS Glacier (AGB-4) by 1955, just a decade later the Navy left the ice biz to the realm of the sparsely-funded Coast Guard.

Since then, all nine of these breakers have been sent to the scrapper, replaced in the 1970s by just two (relatively unarmed) Polar-class icebreakers of which only one was still operational by 2010.

Now 43-years young, the country’s sole polar icebreaker, USCGC Polar Star (WAGB-10), just reached Antarctica on her annual Operation Deep Freeze resupply mission to McMurdo Station– while her crew went unpaid due to the current lapse in funding.

The voyage wasn’t pretty.

U.S. Coast Guard scuba divers work to repair a leak in the shaft seal of the Coast Guard Cutter Polar Star

From the Coast Guard:

During this year’s deployment, one of the ship’s electrical systems began to smoke, causing damage to wiring in an electrical switchboard, and one of the ship’s two evaporators used to make drinkable water failed.

The ship also experienced a leak from the shaft that drives the ship’s propeller, which halted icebreaking operations in order to send scuba divers in the water to repair the seal around the shaft. A hyperbaric chamber on loan from the U.S. Navy aboard the ship allows Coast Guard divers to make external emergency repairs and inspections of the ship’s hull.

The Polar Star also experienced ship-wide power outages while breaking ice. Crew members spent nine hours shutting down the ship’s power plant and rebooting the electrical system in order to remedy the outages.

If a catastrophic event, such as getting stuck in the ice, were to happen to the Healy in the Arctic or to the Polar Star near Antarctica, the U.S. Coast Guard is left without a self-rescue capability.

Yikes.

Can you imagine being a young Coastie E-4 on that ship right now?

So China just launched their first domestically-produced icebreaker, joining a c.1994 Russian-built unit, the 21,000-ton Xue Long (Snow Dragon) previously purchased to double the size of their fleet operating on their new “Polar Silk Road.”

Xue Long II

Named Xue Long 2 (way to branch out) the new 14,000-ton ship is larger than our only true polar icebreaker, USCGC Polar Star, not to mention being about 50-years newer.

Meanwhile, Canada last month picked up a trio of new (to them) medium icebreakers from commercial trade for a song from a company in Sweden. Commissioned into the Canadian Coast Guard, they will revitalize that force until new purpose-built ships can be made.

The new-ish Canadian breakers, soon to be painted red and white

Good thing the USCG isn’t having a problem getting new, modern breakers through Congress.

Oh, wait.

Operation Deep Freeze: Making it by with tape and bubble gum for another year

The country’s only heavy polar icebreaker has pulled it off again..despite the flooding, engine failure, you know, the regular.

The 42-year-old 399-foot USCGC Polar Star (WAGB-10) last week finished cutting a resupply channel through 15 miles of Antarctic ice in the Ross Sea and escorting supply vessels to the frozen continent to resupply McMurdo Station at the tip of Ross Island, the epicenter of the U.S. Antarctic Program (pop. 1200).

The trip was not without drama for the elderly cutter.

From the USCG:

“Although we had less ice this year than last year, we had several engineering challenges to overcome to get to the point where we could position ourselves to moor in McMurdo,” said Capt. Michael Davanzo, the commanding officer of the Polar Star. “Our arrival was delayed due to these challenges, but the crew and I are certainly excited to be here. It’s a unique opportunity for our crewmembers to visit the most remote continent in the world, and in many respects, it makes the hard work worth it.”

On Jan. 16, Polar Star’s shaft seal failed causing flooding in the cutter’s engine room at a rate of approximately 20-gallons per minute. The crew responded quickly, using an emergency shaft seal to stop the flow of freezing, Antarctic water into the vessel. The crew was able dewater the engineering space and effect more permanent repairs to the seal to ensure the watertight integrity of the vessel. There were no injuries as a result of the malfunction.

Flooding was not the only engineering challenge the crew of Polar Star faced during their trek through the thick ice. On Jan. 11, their progress was slowed after the one of the cutter’s three main gas turbines failed. The crew uses the cutter’s main gas turbine power to breakup thick multi-year ice using its propellers. The crew was able to troubleshoot the turbine finding a programming issue between the engine and the cutter’s 1970s-era electrical system. The crew was able to continue their mission in the current ice conditions without the turbine.

“If the Polar Star were to suffer a catastrophic mechanical failure, the Nation would not be able to support heavy icebreaker missions like Operation Deep Freeze, and our Nation has no vessel capable of rescuing the crew if the icebreakers were to fail in the ice,” said Vice Adm. Fred Midgette, commander, U.S. Coast Guard Pacific Area in Alameda, California. “The crewmembers aboard Polar Star not only accomplished their mission, but they did so despite extreme weather and numerous engineering challenges. This is a testament to their dedication and devotion to duty.”

The cutter refueled at McMurdo Station Jan. 18 and continued to develop and maintain the ice channel in preparation for two resupply ships from U.S. Military Sealift Command, Ocean Giant, and Maersk Peary. The crew of Polar Star escorted the vessels to the ice pier at McMurdo Station, an evolution that requires the cutter to travel about 300 yards in front of the supply ships to ensure they safely make it through the narrow ice channel. The crew escorted the Ocean Giant to the ice pier at McMurdo Jan. 27 and conducted their final escort of the Maersk Peary to Antarctica Feb. 2. The crew escorted Maersk Peary safely out of the ice Feb. 6 after supply vessel’s crew transferred their cargo.

Let’s face it: the U.S. Coast Guard has an icebreaker crisis that has been brewing since the 1970s. From WWII through the Ford Administration, the U.S. had the largest military ice-breaking fleet in the world. Then came the inevitable retirement of a host of 8 aging breakers, built for the Navy and armed like destroyers, which were to be replaced by four new 399-foot Polar-class ships.

Well, those four became only two as a result of 1970s budget crisis and they linger on as broken down occasionally functional vessels. Icebreakers take a beating.

Instead of building new heavy icebreakers to military spec, one Congressman wants the Coasties to buy the 12,000-ton Aiviq, an American ice-hardened anchor handling tug supply vessel owned by Edison Chouest Offshore.

Completed in 2012, the commercial vessel is pretty sweet, but in the end had trouble in Alaska trying to do its thing to the point that the cutter USCGC Alex Haley, a medium icebreaker, had to step in as a safety net.

Now, with Shell’s decision to halt Arctic oil exploration, the owners want to sell the gently used $200 million vessel to Uncle Sam for $150 million and a Republican (who has gotten some pretty big contributions from those involved with the ship) is all about it for the Coast Guard– even though the ship isn’t really an icebreaker, isn’t built to military specs, and failed in its only deployment.

“It’s my belief that the Coast Guard would benefit greatly from the initiative taken by Congress to provide funding—without drawing from existing Coast Guard priorities—to minimize the vessel gap, by leasing a medium icebreaker,” said Rep. Duncan Hunter, pimping the Aiviq.

Coast Guard Adm. Charles Michel isn’t impressed and said of the vessel, “This is not a pick-up game for the Coast Guard. We have very specific requirements for our vessels, including international law requirements for assertion of things like navigation rights. … This vessel does not just break ice …”

However, money talks, so there’s that.

Meanwhile, the Duffel Blog nails it:

Coast Guard patches up broke down icebreaker with surfboard repair kit

The nation who at one time had the world’s largest and best-equipped icebreaker fleet has for years been suffering in that department. So much so that the only true heavy breakers we have under U.S. flag, the 399-foot USCGC Polar Star and Polar Sea, are among the oldest ships in the Coast Guard (who is known for having “veteran” platforms) and are uber-cranky.

The 399-foot Polar Star. Top of the line in icebreakers 1977-2010. However, note no visable weapons. For scientific missions these are not needed. However for soverignty missions, are a must.

The crew of the recently returned to duty cutter Polar Star responded to four general emergencies during their most recent deployment to Antarctica. A “general emergency” is a situation in which the crew and the cutter are in serious danger if the not remedied quickly. The crew experienced three fires and one major lube oil leak, which can quickly ignite into fire.

One of which required an out-of-the-box fix.

Petty Officer 1st Class Kevin Oakes, an electrician’s mate aboard the Polar Star, used a surfboard repair kit to fix one of the cutter’s generators after the system shorted out and began smoking. The crew had lost power to one of their propellers en route to Antarctica leaving them with reduced power Dec. 13. The crew could not get specially designed replacement parts for the 40-year-old generator in time for the crew to execute their mission to Antarctica; however, with a little online research and brainstorming, Oakes used one of his shipmate’s surfboard repair kits to fabricate a new replacement part allowing the Polar Star’s crew to continue their mission.
