Below is a news release regarding USCGC Stratton’s recent activities including those in support of UN sanctions against North Korea. For some time, I thought we might have a role in this. Apparently we still have not done an at sea boarding to enforce sanctions. Boardings have been authorized by the UN. That may be the next step. I have linked some previous posts for background.

In two of the photos below, the Stratton is being shadowed by China Coast Guard vessels. The one seen on the left, in the picture with Stratton’s 11 meter boat is one of the new Type 818 cutters are based on the Type 054 frigates, this class cutter is also discussed here. The China CG cutter seen in the photo right center is, I believe, one of their 12,000 ton cutters, the largest in the world. This class is discussed here, with updates in the comments. It appears to be missing the twin 76mm gun seen earlier on this class.

PUERTO PRINCESA, Philippines —The U.S. Coast Guard Cutter Stratton (WMSL 752) pulled into Puerto Princesa October 14, for Maritime Training Activity (MTA) Sama Sama following operations in the Yellow Sea where the crew supported United Nations Security Council Resolution (UNSCR) enforcement against illicit ship-to-ship transfers that violate sanctions against the Democratic People’s Republic of Korea (DPRK).

The operations are a part of the United States’ ongoing contribution to international efforts in combatting DPRK’s maritime sanctions evasion activity. Ship-to-ship transfers of fuel and goods, like coal, going to and from DPRK are prohibited under the UNSCR.

Stratton personnel captured imagery of suspected illicit ship-to-ship transfers and conducted routine activities to detect, deter, and disrupt activities in violation of UNSCR.

Maritime Training Activity (MTA) Sama Sama is a maritime exercise designed to promote regional security cooperation, maintain, and strengthen maritime partnerships and enhance maritime interoperability. This is the first year the Japanese Maritime Defense Force will participate alongside U.S. and Philippine navy counterparts.

The exercise will consist of both shore-based and at-sea activities designed to allow participating navies to advance the complex maritime training utilizing diverse naval platforms and operating areas.

The U.S. Coast Guard has an enduring role in the Indo-Pacific, going back over 150 years. The service’s ongoing deployment of resources to the region directly supports U.S. foreign policy and national security objectives in the Indo-Pacific Strategy and the National Security Strategy.

As both a federal law enforcement agency and an armed force, the U.S. Coast Guard is uniquely positioned to support combatant commanders on all seven continents. The service routinely provides forces in joint military operations worldwide, including the deployment of cutters, boats, aircraft and deployable specialized forces.

“All of Stratton’s operations are designed in accordance with international law and demonstrate that the United States will fly, sail, and operate wherever international law allows,” said Capt. Bob Little, Stratton’s commanding officer. “That is as true in the South and East China Seas, as in other places around the globe. Our efforts in support of enforcing U.N. Security Council Resolutions in the Yellow Sea demonstrate that commitment.”

In 2012 the US Naval Institute published an important article by then CNO Admiral Johnathan Greenert, “Payloads over platforms: Charting a new course.” It starts off, 
“We need to move from ‘luxury-car’ platforms—with their built-in capabilities—toward dependable ‘trucks’ that can handle a changing payload selection. “
–
He suggested that the Navy needs F150 pickups rather than Ferraris. Metaphorically the Webber class could be the Navy’s small Toyota pickup–cheap, reliable, versatile, and economical to operate. 
–
A strong point for the Webber class is that it is probably the smallest and cheapest combatant, being currently manufactured, that can self deploy anywhere in the world (other than the polar regions) with minimal support en route as demonstrated by their self deployment to Hawaii and Alaska and USCGC Olivier F. Berry (WPC-1124)’s successful patrol to the Marshall Islands, 2200 miles from her homeport in Honolulu.
–
As currently equipped there is not a lot of free space apparent on the Webber class, but removing the eight meter “over the horizon boat” would free up a large area where mission modules could be placed. We can think of it as the bed of the pickup.

Potential Missions
 
Countering the Swarm: 
 
The Navy’s most likely first use of a Webber class could be as replacements for the Cyclone class in South West Asia. Countering the large number of Iranian fast inshore attack craft (FIAC) is a mission the Cyclone class is expected to do now, protecting both larger Navy vessels and the tanker traffic that must pass through the Straits of Hormuz.

An earlier post, “Modifying Webber Class Cutters for Duty in SW Asia,” was aimed at this threat as applied to the Coast Guard Webber class that will be going to Southwest Asia. As a minimum the Navy will likely want some form of guided weapon, Perhaps the APKWS would suffice, if provided in sufficient numbers.

The 25mm Mk38 Mod2/3 that are currently mounted on the Webber class might be up-gunned (30, 35, and 40mm guns are all possible) and the mount might also be modified to also launch APKWS. Alternately the Mk38 might be replaced by BAE’s 40mm/70 MK4 and the Toplite gun director c(urrently mounted on the Mk38) could be mounted on the mast to control the 40mm, as the Israelis have done with some of their installations of the system, assuming the 40mm Mk 4 does not weigh too much.

Optimally, the outfit should include Longbow Hellfire. It could probably be mounted as single tube launchers affixed along the sides of the superstructure. I have seen a mockup of such a launcher. The missile itself is only about seven inches in diameter. If willing to replace the boat with missiles, its likely Lockheed could produce a 12 round launcher based on half the launcher being installed on the LCS.

Anti-Ship: 
In other theaters there is likely a desire to have a larger anti-ship missile. 
The Navy has been talking a great deal about “Distributed Lethality.” The concept has its origin in a January 2015 US Naval Institute article by then-Director of Surface Warfare Requirements (OPNAV N96) Rear Admiral Tom Rowden, RAdm. Peter Gumataotao, and RAdm. Peter Fanta. 
 
Rowden’s co-author and successor at N96, Rear Admiral Pete Fanta, continued the drum beat with the memorable phrase, “if it floats, it fights,” suggesting that anti-ship missiles should be put on virtually all units. 
–
On the Webber class, this would most likely the Naval Strike Missile (NSM), recently chosen by the Navy to arm its LCSs and frigates. A four cell launcher could probably replace the boat. The missile is only 13 feet long.

Missile Truck
The Army and Marines have tracked and truck mounted missile launchers. 
 
A new missile, “Deepstrike,” is being developed for these launchers. “The missile will be able to strike targets up to 309 miles away with precision, including moving targets both on land at sea.” (see also)
 
A Webber class equipped with these could function in the same way as the Army and Marine vehicles operating in the littorals and many river systems. Targeting would be provided by offboard sensors through networking. 
–
Anti-Submarine Warfare (ASW)
–
This is probably unlikely, but there might be a place for craft that could perform ASW patrols off ports and amphibious objective areas or around choke points. 
The Canadians have a small containerized towed array sensor that looks like it would fit.

 I have looked at how we might add torpedo tubes to the Webber class that could launch ASW torpedoes, but it is more likely aircraft, most likely helicopters, would be called in to make the actual attack. The ship would be primarily a sensor node, minimizing the requirement to keep ASW Helicopters airborne.

–
120mm Mortar for Naval Surface Fire Support:
–
Another truck like use would be to add this containerized large mortar as a way to provide naval fire support. This weapon is not currently in the US inventory but it does look promising. Guided projectiles are being developed for the 120 mm mortar.
–
Security for MSC’s PrePositioned Afloat Fleet

I am not sure what precautions the Navy has made to protect the ships of the MSC’s PrePositioned Afloat Fleet, but if I were an enemy there are might be strong incentive to destroy these ships that transport the most ready reinforcements of heavy equipment.

Webber class PCs might have a role in protecting these.

 Large Unmanned Surface Vessel. 

The Navy is seeking to procure a medium unmanned surface vessel (MUSV), 12 to 50 meters in length. The Webber class might be the basis for such a vessel. The modular systems described above might also be used on the MUSV. 
–

Visit, Search, Board, and Seizure: 

This is the mission these little ships are built for and, consequently, no change may be necessary. The mission might be stopping and boarding hundreds of small craft as was done off Vietnam as part of Operation Market Time, or it might be enforcing a blockade against Chinese shipping at the Straits providing access to the South China Sea. If resistance is expected there are a number of ways the vessels’ armament could be augmented, including missiles or torpedoes, but in most cases its likely air or backup could be called in. The real advantage is that the Navy would not need to tie down DDGs doing this work, and potentially risk it being damaged by improvised weapons on a vessel being boarded. For more challenging assignments two or three could be teamed with one or two providing boats and boarding teams and the other as a weapons carrier.

Blockading North Korea–A Coast Guard Role?

Posted on by

I have seen several references lately to the possibility of blockading North Korea. A good explanation of why this is apparently being considered is in a Bloomberg article by Retired Admiral James Stavridis, who previously served as Commander, U.S. Southern Command; Commander, U.S. European Command; and NATO Supreme Allied Commander Europe. Quoting Wikipedia,

James George Stavridis (born February 15, 1955) is a retired United States Navy admiral and the current dean of the Fletcher School of Law and Diplomacy at Tufts University, a graduate school for international affairs. Stravidis serves as the chief international diplomacy and national security analyst for NBC News in New York. He is also chairman of the board of the U.S. Naval Institute and a Senior Fellow at the Johns Hopkins University Applied Physics Laboratory.

So perhaps we should consider this as a serious possibility. If it happens, would the Coast Guard have a role?

Certainly Coast Guard boarding teams would be high demand.

North Korea shares borders with South Korea to the South, a long border with China to the North, and a short Border with Russia to the Northeast. If the US attempts to blockade North Korean waters in the Yellow Sea and the Sea of Japan, it will bring US naval units into close proximity to both China and Russia including major Chinese and Russian Navy bases. We have to consider how they might react.

Both China and Russia might be more comfortable if the blockading units operating closest to them were Coast Guard rather than Navy. This applies equally to both ships and aircraft.

Certainly to protect Coast Guard units they would have to have Navy and Air Force backup.
