Bad Day in the Kanmon Straits

 JS Kurama, a Japanese Shirane class helicopter destroyer, has collided with a Korean container ship in the narrow Kanmon strait between Kita-Kyushu and Shimonoseki. (H/T: Information Dissemination)


This is why we do those drills. (Pic via)

The collision reportedly touched off a fire in the forward paint locker off Kurama which seems to have fared the worse of the two.

I've seen the Kanmon strait. It is very narrow and astonishingly busy. I understand it has very severe tidal currents as well. The total width of the strait (not the shipping channel) is only 650 meters. The Daily Yomuri reports that around 70 accidents occur in the straits every year. Heads will no doubt roll over this, but it is not obvious that this is the example of flaming incompetence that such an event normally would be.

It is unclear how much of the damage was due to the collision vs the fire, but if paint thinner in sufficient quantity had a steady supply of air then the fire could have easily reached blast furnace temperatures. With the close proximity of the 5 inch magazines and the sheer intensity of the fire, the fact that the ship is pier-side rather than on the bottom is a testament to her damage control team.

JS Kurama in happier times

At sea, even in peacetime, things can go south in an instant. There are few more dangerous things than a fire on a ship.

Damage control is vital and this requires DC teams. This brings up a related point that our staffing gurus need to be beat over the head with.

A warship is designed to go into harms way, which generally refers to threats greater than a merchant ship. A warship needs to be able to fight while hurt and have enough crew to do damage control while others are fighting the enemy. The number of personell to do this must take into account those killed by the weapons that caused the damage. Given the difficulties that current staffing policies cause in rather benign conditions,  "optimal manning"....isn't.

The Naval Option

Over at Information Dissemination there is a long and detailed post on the logistical implications of the presidents decision to switch from ground based to sea based Ballistic Missile Defense for Europe, which I touched on briefly here.

 There is a LOT involved. It may require as much as 16 ships. I still think it was a defensible decision given the options but it certainly is not a cheap one. Read the whole thing. There is a good discussion in the comments too.

A Few Points About the BMD Concession in Eastern Europe

Technical and life issues have kept me from blogging for a while but the decision of the current administration to abandon a ground based missile defense of Eastern Europe is still garnering considerable comment, most of it quite partisan, very little of it thoughtful.

A modern president is generally not afforded the luxury of having available clear cut good and bad decisions particularly on foreign policy. None of these decisions take place in a vacuum and there are always other considerations and ramifications that interact like the workings of a pachinko machine except that they often result in deaths. Like Bush before him, President Obama is quite often presented with no good options available and like Bush, he is faced with the unenviable task of trying to select the least bad option from a truly vile lot.

 I am certainly no fan or booster of the current president but think that a good case can be made that the decision in this case was in the national interest, in good faith and possibly the least bad available. Here is why.

Recent events in Afganistan and particularly Pakistan highlight the absolute necessity of not relying solely on a logistics line that runs through the Indus valley. However, options are limited by geography.


  The only other way to get to Afganistan is via Iran, or the former Soviet "Stans" to the north. Iran is obviously not an option. There is a short border with China but that is academic as it is in the Hindu Kush range  and the area of China it borders on has an issue with radical Muslim separatists to the extent it is developed at all. The Bush administration had sought to prop up Georgia and Azerbaijan, possibly with an eye to opening another supply route via the Caspian sea. Whether that was really doable is now moot as the Russians have moved into Georgia. Thus any resupply of the Afgan operation that does not go through Pakistan is going to have to take place with Russias blessing.

As I understand it, the facts facing the Obama administration were these:

A:The Russians desperately want to have a visible foreign policy victory for reasons of national prestige and credibility both foreign and domestic. They have railed against the placing of US missile defense systems in Poland. Although this is largely a symbolic thing it tasks them considerably.While we tend to think of this issue in terms of the brutal and wicked oppression the USSR inflicted upon its client states ( not to mention its own people) the Russians concern with foreigners on their frontier is based on a thousand years of slavic blood spilt by invaders.

B: While it has had some recent successes, and can likely be made to work, the US ground based BMD system has had a very chequrered development.

C: The US naval BMD system has not.  (Interestingly, it was developed as an evolutionary outgrowth of the Aegis system almost as an afterthought, and was quite outside of the court intrigues and political power games of the land based system.) While on paper a less capable system, it has proven to be spectacularly successful with a demonstrated capability to not only hit incoming warheads but knock down low flying satellites as well. This system is operational.

D: The range of the system is such that if USN aegis vessels just...you know....happened to be stationed in the Black, Baltic and Adriatic Seas they could provide a decent umbrella against an Iranian Ballistic Missile attack.
Keeping ships on station in those areas is well within the capabilities of the USN even without any homeporting in Gdańsk and Varna...which might well be offered.

Thus by conceding the land based system and replacing it with BMD Aegis the US keeps its word in deed if not word to the nations it promised protection to. The Russians get something they want...a diplomatic victory. However, this doesn't really hurt the US tangibly. 

This might seem like more unilateral self flagellation and concessions ....typical Obama kowtowing. It's not like we have gotten any major concessions from Russ....Oh WAIT*!! NATO can now resupply via Russia and this specifically includes using NATO aircraft in Russian airspace. This is a non trivial consession if there ever was one.

This had the potential to be the rarest of all things, a win, win win, in foreign policy, where nobody actually looses. The only thing that might screw it up would be if we made the announcement that we were yielding to the Russians and breaking the letter of our word to Eastern Europe...on...I don't know....the ANNIVERSARY OF THE INVASION OF POLAND BY GERMANY AND RUSSIA.

Dear GOD! The Stupid BURNS.

Ahem.....

I don't know about my fellow righties, but I did not spend half a year last year saying "Country first!" because it was a catchy little ditty. We need to support the president when he does something right.... at least the parts he doesn't utterly screw up with unfathomably wretched timing. Given Obama's fairly provincial and left wing background there is always going to be something for us to cringe at in abject horror on issues foreign and domestic. But, knee jerk attacks on delicate foreign policy maneuvers in a time of war is not a good idea.

At the very least we ought to reserve judgment until after we have some better handle on how the President is going to respond to McChrystals' request.

Am I off base?
Tilt away in the comments please.

An Exceedingly Weird Sea Story

Eaglespeak has been covering the mystery of the MV Arctic Sea for several days now.

Cliffs Notes version: The Moter Vessel Arctic Sea, a Maltese ship with a Russian crew was siezed by pirates posing as marine police in the...BALTIC SEA. After transiting into the Atlantic all the vessels transponders wee shut off...no one knows where the ship is. Though there have been at least 2 reported sightings one just last night, both are a bit sketchy at best.

See here here and here. There is a bit of analysis at Information Dissemination here.

At the Ship Shopping Bazzar

Over at The Marine Forum there is a very large collection of pictures from the 2008 Euronavale, a European defense contractor convention with a naval focus.

A few trends are visible, and others have commented upon some of them at length. The poster/photographer at MF was obviously drawn to the frontline ship offerings,  in the distance there seem to be a lot of OPVs and similar vessels.



This is understandable as such vessels are the most important vessels in most navies, doing the sort of gunboat tasks that often are ignored by many but are absolutely vital.

There are a lot of logistics and force projection vessels too, which ought to come as no surprise. There are many reasons for this, they are versatile vessels in everything short of a balls out war (The Boxing day Tsunami put the utility of such vessels in the spotlight)...and they can be useful auxiliaries in a major conflict as well.

Submarines seem to be particularly well represented, particularly interesting are small relatively cheap costal units like the Andrasta shown above. There seem to be a lot of Air Independant Propulsion designs as well



There are several export designs from US firms particularly LockMart which is not only offering yet another aegis equipped export version of their LCS (this time retaining the 57mm gun) but also an Aegis corvette that may be aimed at an Israeli requirement. Then there is this...

...The Chuck Norris of FACs...Yes...it appears to be a fast attack craft about 200-220 feet long that has a 5"62 caliber gun on its bow. This is an extreme example of what seems to be a mini trend, larger guns on surface vessels from corvettes on up. Even the French, are offering frigates with the US weapon.....

...and the Russians appear to be offering  100 and even 130mm guns on what appear to be some fairly small corvettes and frigates.


 ( the 3 furthest from the camera in the picture above). Such weapons are good for costal bombardment, but it may be that they are intended for close range antiship use as well. A few 100-130mm shells might well provde a mission kill on a corvette or smaller ship and lots more shells than missles can be carried.

The natural predator of the small costal surface warship is an aircraft but SAMs might make this untenable in some circumstances. So the guns may be a hedge as well as being potentially usefull against small boat swarms,

One other thing needs to be mentioned, though it is not a trend...behold the solar powered Offshore Patrol Vessel (with force projection capability!)


Anyway...discuss.

Vikings VS Pirates: Round 1

Round one goes to the VIKINGS!
 (HT
Eaglespeak)


Early this morning, suspected pirates attacked a Greek Bulk Carrier in the Gulf of Aden.  The pirates fired upon the ship with small arms and RPG (Rocket Propelled Grenade). A distress call was picked up by the EU NAVFOR Swedish warship HSwMS MALMO which immediately proceeded to the area.

HSwMS MALMO made visual contact with the attacking skiff and fired warning shots and flares. The skiff stopped after pursuit and was boarded by a VPD (Vessel Protection Detachment).  Weapons, GPS equipment, grappling hooks and barrels of fuel were found on board the skiff. 7 suspected pirates were captured and are at present being held for further investigation........



The Swedes have stationed two Stockholm class corvettes in the area since last year. The tiny vessels are supported by a tender.

Stockholm and Malmo with their tender
The Stockholm class are interesting. These little ships are intended to operate in the Swedish archipelagos as coast defence craft.Their stats via World Navies Today are as follows:

Displacement: 335 tons full load
Dimensions: 50.5 x 7.5 x 2 meters/165.7 x 24.6 x 6.6 feet
Propulsion: 3 shafts; 2 cruise diesels, 4190 bhp, 20 knots; 1 boost gas turbine, 6,000 shp, 32 knots
Crew: 30
Radar: Sea Giraffe 50HC air/surf search
Sonar: SS304 Spira hull mounted, TSM 2642 MF VDS
Fire Control: 9LV 300 missile control
EW: EWS-095 intercept, Philax decoy RL
Armament: 8 RBS-15 SSM, 1 57mm/70cal DP, 1 40 mm AA, 2 21 inch torpedo tubes, 4 LLS-920 ASW RL


 These numbers are a few years old. They have recently had their ASW capability upgraded with a big variable depth sonar and several 40cm ASW torpedoes in place of the 21 inchers . In any event it is very likely they have landed most heavy weapons for this deployment. This would make them very economical to operate in comparison with any other full fledged warships. In theory quarters normally used by the technicians for the heavy weapons could be utilized by boarding teams.

  The fact that a tender supported vessel of this size is meeting success on the other side of the world goes a long way to validating some of Admiral Cebrowski's Streetfighter concepts.

A slightly larger vessel able to be fitted with with ASROC or ( perhaps more realistically)  and some light AAA weapons like Evolved Seasparrow or RAM might very well be a good fit for the USN.

With their heavy weapons removed they would be fairly cheap to operate in "warm war" operations like this but they might be quickly fitted  with their variable depth sonar and ASW weapons (presumably attended to by reservists) so they would act as sub chasers in a hot war  Such a vessel would be much closer to the original "Streetfighter" concept than the LCS it eventually evolved into.


RDNS Skaden of the Flyvefisken class

The closest to this idea is actually the often mentioned  FLYVEFISKEN class in service with Denmark. It's easy to see something like this fitted with the the Franco-Italian MILAS ASW missile in lieu of their Harpoons acting as sub chaser in a hot war. It would be a comparatively efficient  little gunboat in warm ones. The broad work deck could be used for various cargoes such as relief supplies or the drones the LCS prototypes are now testing....In Coast Guard service such a vessel might also tend bouys.

Vessels able to act as tenders for these vessels already exist. Some of the 'gator navy' amphibious vessels could be modifid to do so and most could provide helicopters as well.

It certainly beats ending up with 200 or fewer ships...

Accidental Q-Ship

Hah!

A group of Somali Pirates attacked a tanker off the horn of Africa several hours ago. This would be sad but not remarkable as the piracy in the area has been bad for years and exploded in the last few months. However the tanker they attempted to board was the FGS Spessart, a German Navy supply ship.

...and so...

The German sailors returned fire and pursued the skiff while also calling in for support. Several naval ships — including a Greek and a Dutch frigate, a Spanish warship and the USS Boxer — sped to the area while a Spanish marine aircraft and two U.S. Marine Cobra helicopters joined the pursuit.
Five hours later, Greek sailors reached the pirate skiff, boarded it and seized the seven suspects and their weapons, including assault rifles and rocket-propelled grenades, the Greek navy said. The suspects were disarmed and transferred for questioning to the German frigate Rheinland-Pfalz where they remain Monday, pending a decision on whether they will be legally prosecuted, Christensen said.


Wasp, meet sledgehammer.

More Ideas for Naval Numbers on a Budget

As has been mentioned here before, the combination of increasing unit costs, aging hulls in need of replacement an increase in the numbers of units needed and the unforced budget debacle facing the treasury has created a procurement conundrum for the US Navy and Coast Guard. 

We need ships, lots of ships in a decade or less but given the economy we are likely to have have very little money

Given the high tempo 'medical diplomacy' operations pioneered by the Bush administration as well as the need to respond to disasters such as typhoons, volcanoes, plagues and tsunamis at least some of the vessels we build ought to have some sort of cargo capacity and a larger than average medical facility.

A converted or redesigned merchant design would seem to be the logical choice but if these are to replace the FFGs then it is important to ensure that such a vessel be capable of providing something in the event of a hot war other than terrible ways for bluejackets to die.

This is not unheard of. The Flower class sloops of world war one were built to commercial standards, had a modest cargo capacity and were intended to serve as minesweepers, troopers, escorts, picket vessels, gunboats and light replenishment ships. They were not frontline ships but they were not helpless either and provided sterling service as convoy escorts and on gunboat duties between the wars.

The challenges of modern warfare mean that an electronics fit is needed of course so such a ship will bear no relation in cost to whatever merchant ship it is designed from, but it might cost something akin to a modern corvette.

Lets take a standard American containership design, the Philidelphia Class, and assume the aft deck is used for helicopter operation and the aft holds are used as a flex deck for small craft and Littoral combat ship modules. The holds forward of the bridge have ample room for containers that can contain everything from food to hospital or war supplies. I'd use the midships below decks space (where pitching would be minimized )for a big hospital and a secondary helipad (if only to directly service the hospital). This would not have the capability of the Mercy or Comfort but it could conceivably approach that of the LHAs and could do a LOT of good on mercy missions.
It might be less threatening as well. Note that while such a vessel would not be a hospital ship, and would therefore be targetable by law, most people we are likely to lock horns with  are unpersuaded by appeals to human decency anyway. Forward of the hospital area, even  2-400  containers would be an impressive ammount of relief supplies in peacetime and still leave room for 16-32 VLS cells for ESSM. The large helideck would give a decent helicopter borne ASW and possibly even minesweeping  capability in wartime especially if during a major war something like SCADS or the old ARAPAHO concept were put into place along the lines of this....

We might be able to build a dozen or more of these in commercial yards over the next few years. This would have the added benefit of propping up and stimulating our shipyard capacity during dark economic times in a way that dog parks in California are unlikely to do. Such a program might appeal to the current leadership in ways a more conventional naval procurement would not.

These would probably  not able to be procured in the same numbers that 600 ton corvettes might but they could ad a considerable complementary capability to the low end of the hi/lo mix.


At any rate it may bear considering. Any thoughts?


UPDATE: In the comments James Rummel takes the time to comment at length about the idea and makes some lucid points but also indicates that I may have been unclear about as few things.
These are not replacemtnts for our cruisers and destroyers, but a low end complement. If they replace anything they might best replace part of the production run of the LCS vessels....
IF they can be procured more economically and IF they would be a net improvement in capability . These are indeed big "IFs".
There are certainly all sorts of issues with this concept both political and practical. However, I am of the opinion that, if built, these would be warships with peacetime duties similar to a 19th century gunboat but with much greater utility to assist the main force.

Mr Rummel makes another comment that deserves mention.

You suggest that this is only a temporary change until economic conditions improve.  But anyone interested in military procurement will tell you in a heartbeat that it would be almost impossible to get Congress to pony up for actual, very expensive warships after a decade of building cheaper cargo ships.  Once the change is made, there is no going back.


This is a  very real concern.

It is probably one reason the navy doesn't build some smaller carriers to increase survivability through numbers. This was tried in the 70s ant the congress made it plain that it would ONLY buy the smaller carriers and not increase numbers...thereby gutting the navy but giving the impression that congress was providing modern ships.

It does not always work out that way though.

In the 1880's the UKs shipbuilding program was terribly screwed up, with problems that included cost overruns, excessively long build times, ships massively over budget as well as overdue, quality control issues, problems integrating new technologies and simple corruption (sound familiar?). The response was to, for a time,  order only second line vessels such as gunboats and auxiliaries as well as a few experimental technology test beds such as experimental high speed craft (the torpedo boats).

These were often ordered outside the usual defense procurement clique.
In the meantime the procurement system was overhauled, investment was made in physical plant improvements at the shipyards and  the procurement system was reformed, Concurrently, a determination of what sort of vessels were needed was made. Then rational, attainable requirements for the various types of vessels were drawn up that matched the then current technologies, the national strategy of the time as well as the gamut of potential scenarios.

After several years of building gunboats and finishing the dubious vessels that were already ordered, the Royal Navy began building ships under the Naval Defence Act. William Whites design team produced the finest ships that had been built up to that time and for nearly two decades, every subsequent class was an improvement on their design predecessor in some way.
From that point until WW1 the British Royal Navy built a balanced fleet and produced some of the best, most economical; and cost effective ships of their day.

So while the pitfall Mr Rummel points out is very real, it can in fact be avoided if care is taken and the legislature acts in good faith...another very big "IF".
