Canada’s Arctic Offshore Patrol Ship (AOPS)

Ran across an interesting presentation of the design of Canada’s projected Arctic Offshore Patrol ship (pdf). This apparently dates back to 2008, but it is the most detailed presentation I have seen on their concept.

While probably not as capable as the Healey, which is more than twice as large, something similar might be able to fill the Coast Guard’s stated requirement for two additional medium icebreakers.

The design has several interesting features

  • It is designed to IACS Polar Class 5, “Year-round operation in medium first-year ice which may include old ice inclusions” with a double acting hull form.
  • It includes three RHIBs and a landing craft, in addition to two 70 man covered lifeboats.
  • Flight Deck and hanger sized to support a helicopter larger than the H-60 (the CH-148).
  • Propulsion is diesel electric using Azipods. Power is provided by four generators  (Can’t say I’m comfortable with how they achieved redundancy by using a centerline bulkhead to split two main machinery spaces into four).
  • It incorporates provision for carrying five containers, and has a 10 ton crane on the main deck aft.
  • Requires a relatively small crew (45) but includes provision for an additional 40.

Compared to the Wind Class Icebreakers that once made up most to the Coast Guard fleet, they are slightly larger (6,940 tons vs 6,500), much longer (359.5 ft vs 269), narrower (59.7 ft vs 63.5), much more powerful (20,100 HP vs 12,000), and faster (20 knots vs 16.8).

Compared to the Norwegian Coast Guard vessel Svalbard on which it is based it is 50% more powerful.

We can’t be sure at this point, that this is the ship the Canadian’s will build, but it’s probably pretty close.

 

 

 

Wolf in Sheep’s Clothing

I got these images second hand (perhaps third, forth, or fifth hand), so I can’t say where they came from or the date taken, but I think they are instructive for how they show how a vessel can be much more than it appears. Reportedly, this is a Russian trawler that was stationed off the Fleet Ballistic Missile Submarine base at Holy Lock, Scotland. That they were not there to fish was general knowledge, but I think the extent of modifications to the underwater body, particularly the apparent addition of torpedo tubes, may be a bit of a surprise.

Looking a bit closer:

State of the Coast Guard Address/New Standing Orders (Pub 3)

The Commandant issued his State of the Coast Guard address today. You can access it here. I had trouble with the video, but the text is also there (Remarks from ADM Robert Papp (14 pages – 178.93KB)). It is a good speech, as you might expect. He spoke from Alameda, recognizing the increasing importance of the Pacific and the Arctic that together constitutes approximately 84% of the US EEZ.

It is worth the read. There weren’t too many operational specifics but there was reference one specific planned future operation, seasonal deployment of the Bertholf and buoy tenders to the Arctic.

The same page has a pdf download for what the Commandant likened to standing order, Coast Guard Publication 3-0 (Pub 3), Operations (56 pages – 5.55 MB).

Nautical Museum/Light House/Tall Ship Info

Ran across a site some of you might find interesting. It provides a way to find museums, light houses and tall ships throughout the US and at least in some cases in Canada. The particular page I linked also has a couple of USCGC Eagle videos and the schedule for the twelve ports the Eagle will visit in conjunction with “Operation Sail.”

Navy Partner being Disestablished

Interesting little note that proves again actions speak louder than words. An asset that supported the drug interdiction effort and helped in the Hurricane Katrina disaster relief is going away.

“…the Navy proposes to decommission a squadron at the air station in Belle Chasse, a move that would eliminate the only naval aviation unit dedicated to stemming the flow of illegal narcotics into the United States. Under the 2013 spending plan released Monday, the Navy Reserve’s Carrier Airborne Early Warning Squadron 77 would cease to exist Sept. 30…. the Navy ‘remains committed’ to countering narcotics trafficking.”

“VAW-77…played an instrumental role in the massive rescue operation following Hurricane Katrina. With their electronics and radar…the aircrews helped control airspace crowded with rescue helicopters. The squadron takes credit for rescuing 1,840 people in the New Orleans area.”

I suppose the surface surveillance capability may be replace by the BAMS program, still too frequently, it seems, a capability is removed with the promise that it will be replaced by a wonderful new system, only to see the new system become unaffordable and never come to fruition.

New Budget Cancels Plan for Last Two NSCs

Defensedaily.com is reporting that while the FY 2013 budget request would fund the sixth National Security Cutter, additional purchases would be delayed while the Department reevaluates its needs.

Homeland Security Secretary Janet Napolitano said yesterday that the reason for proposing a pause in the NSC program is due to budget constraints as well as examining how it fits with the Navy’s plans.

“We will look at [NSC’s] seven and eight in light of what the Navy is doing,” Napolitano told the House Appropriations Homeland Security Subcommittee during a hearing to examine her department’s budget request. “So we need to look at what the DoD is doing with respect to their own force lay down to see what we need to be putting in the acquisition pipeline.”

Presumably this ties in with the Navy’s review of their own programs.

It has been recognized for a long time that current plans would require a substantial increase in AC&I funding. The GAO has called the program of record “unachievable.”

While I certainly applaud coordination with DOD, this could mean a lot of different things.

Will the Navy try to move the Littoral Combat Ship program to the CG as replacement for the OPC?

Will the Navy try to avoid cutting their building programs further by suggesting that the CG does not need large ships for drug enforcement because they will supply platforms for CG boarding teams? or

This might not be so bad. When Under Secretary of the Navy Robert O. Work  discusses American Sea Power, he almost never fails to mention the contribution of the Coast Guard. Perhaps some additional thought will go into how possible military roles should be reflected in the requirements for Offshore Patrol Cutters (OPC), Icebreakers, and other assets.

An OPC that  reflects military requirements would almost certainly be larger and more capable than one designed only to meet peacetime requirements that might otherwise have been forced on the CG in an austere budget climate. Those greater capabilities probably would also make it a more capable CG asset in peacetime.

The differences might include a larger hull, more speed, better aviation facilities, and better communications and sensors, possibly including a towed array that would be useful for detecting drug subs (both true subs and self propelled semi-submersibles).

Its not clear yet, if this is a disaster or an opportunity. Perhaps a new way of justifying CG assets will come out of this, and the government will see that putting money in the CG is a sound investment.

Less Lethal Weapons on USVs

News of the melding of two emerging technologies of interest to the Coast Guard.The Navy’s US Fleet Forces command is experimenting with putting “non-lethal” weapons on unmanned surface vehicles.

“Operating in autonomous and semi-autonomous modes, the small militarized boats are equipped to employ a directional acoustic hailer, eye dazzling laser and flash-bang munitions; each non-lethal weapon was carefully-orchestrated to respond to a set of threatening behaviors from intruder vessels.”

 

Lessons from a fishing boat?

gCaptain is reporting the design of a new 184 foot long, long line fishing vessel, one of the largest in the world, intended for operation in Alaskan waters. It bears more than a little resemblance to a buoy tender. The thing I found interesting is that it uses diesel electric propulsion.

“In addition to the vessels impressive fishing capabilities, the Northern Leader will be designed to be fully diesel-electric with emphasis on minimal environmental impact and lightest carbon footprint. The vessel’s propulsion will be powered by two Schottel Z-Drive rudder propellers and a Schottel tunnel thruster.  The diesel generating system, provided by NC Power Systems of Seattle, will consist of four Caterpillar C32 gensets rated at 715 kW each, two Caterpillar C18′s rated at 425 kW each, and one Caterpillar C9 rated at 238 kW.”

The four largest generators total 2,860 kW or 3,834 HP. Total generating capacity is 3,948 kW or 5,292 HP. If diesel electric propulsion is used for a fishing boat, it is a likely its an economically viable solution.

What Might Coast Guard Cutters do in Wartime? Part 2, Coast Guard Roles

https://i0.wp.com/upload.wikimedia.org/wikipedia/commons/8/83/USCGC_Spencer_WPG-36.jpg

This is the second of two parts. The first part focusing on what I believe are the current shortfalls in the US Navy force structure is here.

Since part one, additional cuts to the Navy’s plans have been announce. Attack submarines which have an important ASW role are now expected to decline from a current 55 to 40 in 2030 and all SSGNs will be removed from service. Additionally the Navy will prematurely retire seven cruisers and two amphibious warfare ships. The planned five year building program is going from 57 ships to 41.

Now we will look more closely at what Coast Guard Cutters may be called upon to do in future conflicts, what changes to our existing force might be prudent, and desirable characteristics for future cutters. Continue reading
