Unmanned Air Systems, Small Enough for WPB?

Flightglobal.com is reporting the Israelis are seeking an Unmanned Air System (UAS) for their Dvora class patrol boats (here, here, and here) that range in length from 71 to 86 feet and 45 to 54 tons (smaller than a CG 87 foot Marine Protector Class WPBs). Steadicopter showed its Black Eagle 50, as a possible contender.

Perhaps it would not be unreasonable for the Coast Guard to start considering unmanned systems to complement the Webber Class that are six times as large.

Philippines and China in Standoff–former USCGC Center Stage

The former USCGC Hamilton, now BRP Gregorio del Pilar, is at the center of a standoff with the Chinese over a remote atoll shaped group of rocks and shallows called variously Scarborough (or Panatag) Reef or Shoal.

Both the Chinese and the Philippines claim sovereignty.

A Philippine patrol plane located eight Chinese fishing vessels inside the atoll. With the Gregorio del Pilar now on scene, two Chinese Maritime Surveillance vessels are blocking Philippine fisheries enforcement action against the fishing vessels and the Chinese are demanding the Philippine Navy depart their waters; while the Philippines is asserting it will enforce its sovereignty. Diplomacy is given lip service, but the standoff is ongoing. The US has a treaty obligation to the Philippines (subject to interpretation of course) and there are calls for US assistance.

A long discussion from the Philippine point of view here.

Black Eye for NATO and European SAR Organizations

NATO and European SAR organizations are being blamed for the death of 63 refugees from the fighting in Libya. The voyage started with 72 refugees, 50 men, 20 women, and two babies. Fifteen days later, when the craft drifted back to Libya, only ten remained alive and one of those subsequently died.

The media (CNN story here, MailOnline (UK) here) seems to have concentrated on this case as emblematic of failure, but it does not begin to tell the story. According to Aljazeera, “The UN Refugee Agency (UNHCR) estimates that roughly 50,000 people attempted to cross the Mediterranean by boat in 2011 and close to 2,000 drowned.”

To the outside observer there seem to have been many opportunities to rescue the refugees. Not having done so is seen as racist. NATO and European Coast Guards are being blamed, but might simply have been overwhelmed.

Clearly rescue organizations are being held to a very high standards. It is not enough that they rescue the vast majority of those in distress, they must rescue everyone without fail. It is not unlikely that once, perhaps several times, these organizations responded to reports of the boat adrift, located a boat in the area and assumed the mission was accomplished.

Its not unlikely our Coast Guard will find itself in a similar situation again.

 

 

What Does It Take to Sink a Ship, Illustrated

A little over a year ago, I published a post entitled “What Does It Take to Sink a Ship.” It has proven perhaps my most widely read post. The recent sinking of the Japanese fishing vessel Ryou-Un Maru beautifully illustrates the point that ships can be very hard to sink by gun fire.

120405-G-ZZ999-The sinking of the Japanese fishing vessel Ryou-un Maru

  • Title: GULF OF ALASKA – The Japanese fishing vessel, Ryou-Un Maru
  • Summary: GULF OF ALASKA – The Japanese fishing vessel, Ryou-Un Maru, shows significant signs of damage after the Coast Guard Cutter Anancapa fired explosive ammunition into it 180 miles west of the Southeast Alaskan coast April 5, 2012.

Reportedly the USCGC Anacapa began the operation at 13:00 and the Ryou-Un Maru sank at 18:15. It appears that the F/V may have been hit 100 times by explosive 25mm projectiles. With no crew aboard to do damage control and probably with no real measures taken to ensure water tight doors were closed, it stayed afloat for over five hours and ultimately the Anacapa resorted to pumping water into the vessel to sink it.

  • Title: 120405-G-RS249-005-USCG responds to Japanese vessel in Gulf of Alaska
  • Summary: GULF OF ALASKA – The Coast Guard Cutter Anacapa crew douses the adrift Japanese vessel with water after a gunnery exercise 180 miles west of the Southeast Alaskan coast April 5, 2012. The crew was successful and sank the vessel at 6:15 p.m. in 6,000 feet

This was a very small ship, probably less than 500 tons, the implications for our ability to stop a medium to large vessel with a determined crew on board, bent on using the vessel for a terrorist act in an American port should be obvious. With even crude and unsophisticated measures to protect vital machinery and control functions, a ship can resist a great deal of gunfire and continue to its objective.

Another New icebreaker, No Not Coast Guard

gCaptain reports, Shell oil recently took delivery of a 360 foot icebreaker anchor handling vessel. This is the fourth icebreaker built by Edison Chouest Offshore in the last two decades. Two of them (Laurence M. Gould and Nathaniel B. Palmer) were chartered by the National Science Foundation to support their high latitude work.

Reportedly this is part of a continuing trend toward larger vessels to support oil drilling as it moves further off shore.

While it is certainly no Polar Class, it appears to be larger than either the Wind Class or the Glacier. Its good to know that if we wanted to quickly build an arctic patrol vessel that would not break the bank (reported cost $200M), there is at least one American shipyard up to the task.

 

 

Unconventional Chinese Rescue Cutter

The Chinese have built an interesting little ship with a trimaran hull, that appears to designed for one of their several coast guard type organizations. It is designated “North Rescue 143.”

It looks a little like a cross between a 110 and an Independence Class Littoral Combat Ship.

Of course this is not the first time the Chinese have shown an interest in non-conventional hull forms. There had been some indication they intended to use the basic form of their catamaran Type 022 (Houbei Class) missile boats as a patrol boat.
