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.
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.
“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.
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.
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.
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?
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.
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.
Can you imagine being a young Coastie E-4 on that ship right now?
While your old lady (or man) sends you emails that the light bill is due and check on the 15th was for $0.00?
Politics aside, be sure, if you are able, to contribute to your local efforts to take care of USCG families in your area, and keep those deployed in your thoughts.
