Someone deserves a medal here

Filed under: Britain, Military — Tags: , — Nicholas @ 11:57

If this Guardian report is true, I hope that Royston Smith is on the next honours list:

Southampton city council leader, Royston Smith, was visiting the submarine with other dignitaries while it was berthed at the Eastern Docks on a five-day visit to the city.

He described how he “wrestled” the gunman to the ground in the submarine’s control room as he tried to stop him.

“Two shots were fired, straight after he entered the control room again and began shooting again,” Smith told the BBC.

“I ran towards him, I pushed him against the wall, we wrestled to take the gun from him. He fired again, I wrestled again to get the weapon from him. I pushed him to another wall, I wrestled him to the ground and managed to take the weapon away from him then others came to help to restrain him.”

He said a group of schoolchildren had left the submarine shortly before the attack.

That’s a civilian, charging a gunman armed with a battle rifle, and disarming him before the trained military personnel could intervene. There are very few people who could have reacted so quickly — and correctly — in that situation. That’s heroism.

Unmanned sub hunter

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 10:25

Lewis Page looks at the Continuous Trail Unmanned Vessel (ACTUV):

No doubt regular readers will recall the US military’s cunning plan to develop unmanned submarine-hunting robotic frigates — warships which would prowl the oceans like automated Mary Celestes, remorselessly tracking enemy submarines regardless of how their pale, sweaty, malodorous captains might twist and turn.

The Anti-submarine warfare Continuous Trail Unmanned Vessel (ACTUV) project is intended to produce “an X-ship founded on the assumption that no person steps aboard at any point in its operating cycle”. The uncrewed frigate would have enough range and endurance for “global, months long deployments with no underway human maintenance”, being able to cross oceans and fight its battles largely without any human input — communications back to base would be “intermittent”, according to DARPA.

As you might imagine, there are lots of potential issues to sending an armed, unmanned ship out into the ocean, including how to handle interactions with other users of the sea lanes. It’d be worse than embarassing to the US Navy to have one of their fancy new ACTUV vessels get tangled up in a fishing net or get caught in the middle of a regatta.

Perhaps unsurprisingly, then, it has been decided that the best way to hammer out a set of tactics for ACTUVs is to develop a game-style simulation pitting ACTUV against submarine and get people to play it — so crowdsourcing the methods and tactical principles that will then be coded into the robo-frigates’ AIs.

The new game — from which these visuals are drawn — is called ACTUV Tactics. The game engine is used in various military sims and in the Dangerous Waters commercial release of 2005. [. . .]. In it, a player tries to find and track an enemy submarine while avoiding collisions with commercial vessels and the like. Various different proposed models of ACTUV robo-frigate are available: Gator, Remora, Seahorse, Shark and Triton.

RAF has only 69 qualified pilots for Typhoon fighters?

Filed under: Africa, Britain, Military — Tags: , , , — Nicholas @ 11:44

I’m not sure how an organization which recently performed brilliantly in their bureaucratic and political struggle against their arch-enemies in the Royal Navy can also be this stupid:

Since the conflict began, a squadron of 18 RAF Typhoon pilots has enforced the Libya no-fly zone from an air base in southern Italy. However, a shortage of qualified fighter pilots means the RAF may not have enough to replace all of them when the squadron has to rotate in a few weeks.

The situation is so serious that the RAF has halted the teaching of trainee Typhoon pilots so instructors can be drafted on to the front line, according to air force sources. The handful of pilots used for air shows will also be withdrawn from displays this summer.

The RAF put in a merciless performance in the recent defence review negotiations, eliminating three two aircraft carriers and downing all of the remaining Harrier jets. Perhaps their emphasis on bureaucratic and political in-fighting meant they had no time or energy to train pilots for their shiny new aircraft?

The Government’s decision to decommission HMS Ark Royal, Harrier jump jets and the Nimrod reconnaissance aircraft — all of which could have played a role in the Libya conflict — has exacerbated the problem. Serving RAF pilots contacted The Daily Telegraph to warn of the risks to the Libya operation. “We have a declining pool of pilots,” one said. “There’s less people to do twice as much work. If we are not training any more we are going to run out of personnel very soon.”

[. . .]

Out of 69 qualified RAF Typhoon pilots, including instructors, 18 are in southern Italy flying missions over Libya. Of the rest, 24 are committed to the Quick Reaction Alert protecting Britain’s air space and six are in the Falklands in a similar role. A further six are being used to train Saudi Arabian air force pilots. That leaves only 15 to replace those currently based in Italy.

Because of the intensity of flying on operations, pilots deploy for a maximum of two months at a time and the replacements for those currently enforcing the no-fly zone in Libya will be expected to deploy at the end of next month.

QotD: One-minute Imperialism

Filed under: Africa, Military, Quotations — Tags: , , , , — Nicholas @ 10:17

It is the height of recklessness, a kind of blasé barbarism, to start a war without knowing what the war is for. We are witnessing the transformation of Libya into a giant laboratory for a zany, unpredictable experiment to see what happens when you mix Tomahawk missiles with a volatile Arab uprising. It makes even the ill-considered debacles in Iraq and Afghanistan look like the height of rationality in comparison.

The made-up nature of the war, its speedy and brainless cobbling together by Western leaders keen to make a quick point by firing a few hundred missiles at Gaddafi, explains why the so-called Western alliance is so spectacularly flimsy. This must be the most shortlived alliance in human history. It lasted about 24 hours — at a push 36 hours — before Washington announced that it would ‘tone down’ its involvement and agitate for NATO to take over. Perhaps keen to satisfy the needs of the 24-hour rolling news agenda, America has just overseen the world’s first-ever outburst of 24-hour imperialism.

Libya operations do not support UK’s recent defence decisions

Filed under: Africa, Britain, Military — Tags: , , , , , — Nicholas @ 12:15

Lewis Page is doing an analysis of the current British involvement in Libya. He points out that many of the recent decisions by the British government are not being proven by the actual pattern of combat:

Recent combat operations by British and allied forces in Libya are beginning to tell us a lot: not so much about the future of Libya, which remains up for grabs, but about the tools one actually needs for fighting real-world wars against real-world enemy armed forces.

The vast bulk of our own armed forces are set up, equipped and focused on this type of mission — rather than the hugely more common one of battling guerillas and insurgents, as seen in Afghanistan — so the Libyan operations of the last week are very important to us at a time of shrinking budgets and worldwide turbulence. Libya is telling us how well the Coalition government did in its recent Strategic Defence and Security Review — and bluntly, it is showing that the Review was a fiasco.

Mr. Page has not been a fan of the Eurofighter, and sees the initial stages of the Libyan campaign as proving the investment is so much wasted money:

. . . highly advanced specialist air-to-air combat capability has not been necessary here. The RAF has rushed Eurofighter Typhoons to Italy — they were the first British aircraft to arrive there, in fact — but they are pure air-to-air planes at the moment (the RAF doesn’t expect to have them properly ready for use as bombers until 2018). The odds are that they will not fire a shot — and if they do it will be to swat down some rusty old MiG flown by a suicidal pilot. For this job, much cheaper fighters would have been more than adequate: say American F-18s or F-16s, or even our previous embarrassing Tornado F3, now retired.

So, point one: buying the Eurofighter remains a stupid idea on our part.

Canada’s F-18 aircraft have seen more combat in Libyan airspace than the RAF’s Eurofighters, because the F-18 has a ground-attack capability.

On the other hand, Mr. Page rejoiced at the overdue decision to scrap the Nimrod, but the ancient-but-terribly-expensive aircraft appear to have a valid role to play in Libya:

Point two: electronic warfare and AWACS planes are useful, even against the minor regimes who we might genuinely fight in the real world. The decision to keep both in the recent UK Defence Review was sensible (the Nimrod R1 Elint planes were marked for the bin — and have been temporarily been reprieved for duty in the Libyan situation — but replacement “Rivet Joint” aircraft are on order).

The use of the Tornado aircraft for very long range attacks seems like a waste of time and resources:

We are told in official announcements that some 112 Tomahawk cruise missiles were used in the initial strike at the weekend, launched from US and British warships and submarines off the Libyan coast. We are also told that “a number” of Storm Shadow shorter-ranged cruise missiles were launched from Tornado bombers. The Tornadoes had flown 3,000 miles from Kent Norfolk to do so, requiring the aid of repeated air-to-air refuelling assistance both on the way out and on the way back.

We can be pretty sure what the unspecified number of Storm Shadows was, as the Tornado can carry only one Storm Shadow into combat and we are told that a total of four Tornadoes have been assigned to Operation ELLAMY, the British contribution to the Libyan fighting. Some accounts suggest that in fact only three Storm Shadows were fired in the initial long-range Tornado raid.

[. . .]

Our lesson from a shooting war against a national air force — the first we have fought since 1982 — is that you don’t suppress enemy air defences of the sort you actually meet in the real world with deep penetration bombers and clever air-launched weapons (far less with stealth planes). You do it with AWACS and Elint planes and Tomahawks launched from the sea.

And speaking of the sea . . . what about the Royal Navy contribution to the Libya campaign?

Don’t we just wish we had a carrier off Libya now? Shame we scrapped ours just months ago. Nice work, Mr Cameron

There can be little doubt that the Harrier would also have been better for Libya. The Harrier fleet actually had more aircraft modernised to drop the latest smart weaponry — it was a superior battlefield strike plane — and it was cheaper to run. Best of all, it could operate from our also-recently-axed pocket aircraft carriers right off the coast and thus reach the theatre of action in minutes rather than hours. France and the USA both have carriers operating off the Libyan coast right now, but our foolish decisions in the recent review have left us on the sidelines.

Mr. Page still thinks the Royal Navy got royally shafted by the RAF:

Point four: The decisions taken over many years to whittle down the Harrier force to the point where it was barely viable – and then finally axe it in the Review — were totally wrong. Instead the Tornado should have been scrapped. Our present-day fleet of more than 130 of these cripplingly expensive-to-run, slow, lumbering low-altitude jets, assisted by similarly costly tanker planes, has offered us an utterly pathetic capability to deliver three or four dodgy missiles into Libya and a minimalist air support capability thereafter.

Even by the time of the Review, when the Harrier fleet was down to an almost unviable 44 jets, it would have made more sense to keep them, scrap the Tornado and buy or lease some nice cheap F-18s from America to bulk up our strike forces somewhat. The RAF should be ashamed of itself for manipulating the Prime Minister into keeping Tornado; heads should roll.

Is it too late to save the Ark Royal and Invincible? Yes:

To make the situation even more pathetic:

Once, this would have been a sight to strike fear into the hearts of any enemy fleet, a vivid portrait of the naval clout of this island nation.

But, today, these are two ghost ships. This depressing photograph taken yesterday is merely a reminder of the current state of the Royal Navy. Until recently, Britain had three aircraft carriers. The latest round of defence cuts means we have just one carrier — HMS Illustrious — and no planes on board. It only does choppers these days.

Invincible is bound for the Middle East. But Colonel Gaddafi need have no fears about this gallant old warhorse. In a few days’ time she will be off the coast of Libya but she won’t be stopping. She’ll be pressing straight on for Turkey where she is due to be cut up — or ‘recycled’ as an MoD spokesman insisted yesterday.

Back to Mr. Page’s conclusions (not that there should be any surprises based on the examples I’ve included):

Summing up, the lesson of Libya is that the recent Defence Review was, indeed, a dismal failure. RAF empire-preservation saddled us with the useless Tornado at the cost of our carrier capability. The army insisted on preserving pointless tanks and big guns and as a result we are not pulling our weight in Helmand — a war we more or less unilaterally started in 2005 — and we have no option to intervene on the ground in Libya seriously.

The navy made no real effort to help matters. It might have managed to preserve a carrier capability by making concessions on its pointless frigate flotilla, but this it refused to do.

[. . .]

But the chance to change things is not gone yet. So badly fudged were the Strategic Defence and Security Review’s figures that more reorganisation remains on the cards; in effect, a review of the Review is now very likely. The chance is still there to scrap the cripplingly expensive Tornado and Eurofighter altogether and replace them with cheap, excellent F-18s — so getting our carrier capability back in just a few years, as well. When the F-35C actually becomes affordable at last around 2025 we can buy some — by that point its Stealth and other new technologies might actually be becoming relevant for wars that might really happen, along the lines of Libya.

Naming conventions, military style

Filed under: Africa, France, Military, USA — Tags: , , — Nicholas @ 12:44

Jon sent me this link on the highly inappropriate name given to the military actions against Libya:

As Jonah Goldberg wrote, the name approved by Barack Obama, Odyssey Dawn, sends a slightly different message than perhaps intended:

Odyssey, after all, is a term for a very long and involved adventure. If memory serves, Odysseus took a very long time to come home. Maybe it’s just a coincidence that the Pentagon came up with a label that basically says this is beginning of an extended, seemingly endless, journey.

I had the exact same thought — and shouldn’t a man with a classical Ivy League education have caught that reference? Even if Obama was not familiar with The Odyssey, the dictionary definition of “odyssey” should have raised a red flag:

Definition of ODYSSEY
1: a long wandering or voyage usually marked by many changes of fortune

For a mission that is supposed to be counted in “days, not weeks,” it looks like Obama’s choice of mission names is an epic failure.

I’d written, quite some time back, about the national differences in how Anglosphere nations named their military operations:

I often note with amusement the significant differences in naming conventions for military operations between the US and the rest of the “Anglosphere”. A typical US Army operation might be “Operation Devastating Earthshatterer”, while a British or Canadian equivalent might be “Operation Broken Teaspoon” or “Operation Goalie Glove”. (I’ll pass up on the urge to attribute something mockery-tinged to French codenames . . . but only because Babelfish didn’t give me a useful translation for “Operation Wet Knickers” or “Operation Big Girl’s Blouse”).

Not that there’s anything wrong with a dose of belligerant overkill in your naming conventions. . .

How quickly things change: the former “cheese-eating surrender monkeys” have become the leaders of the military coalition, while the Americans were on the verge of transforming into “burger-eating surrender monkeys”.

The nuclear power industry’s technological lock-in

Filed under: Economics, History, Science, Technology — Tags: , , , — Nicholas @ 09:20

Leon Neyfakh looks at how light water reactors became the “default” choice of the nuclear power industry:

Japan’s reactors are “light water” reactors, whose safety depends on an uninterrupted power supply to circulate water quickly around the hot core. A light water system is not the only way to design a nuclear reactor. But because of the way the commercial nuclear power industry developed in its early years, it’s virtually the only type of reactor used in nuclear power plants today. Even though there might be better technologies out there, light water is the one that utility companies know how to build, and that governments have historically been willing to fund.

Economists call this problem “technological lock-in”: The term refers to the process by which one new technology can prevail over another for no good reason other than circumstance and inertia. The best-known example of technological lock-in comes from the 1970s, when VHS and Betamax, two different kinds of videotape, competed in the market until VHS gained a slight lead and then leveraged it to total domination. Whether the VHS format was actually superior to Betamax didn’t matter. After the lock-in, consumers no longer had a choice.

Much more is at stake in nuclear power. Some reactor designs are safer than others in an accident; some are more efficient than others in their use of fuel and produce less nuclear waste. The fact that the industry settled on light water over any number of alternatives was determined in the years after World War II, when the US Atomic Energy Commission and Navy Admiral Hyman Rickover made a series of hasty decisions that irreversibly set the course for how nuclear power plants around the world are built today.

“There were lots and lots of ideas floating around, and they essentially lost when light water came to dominate,” said Robin Cowan, a professor at the University of Strasbourg and the University of Maastricht who wrote a 1990 paper in The Journal of Economic History about the nuclear industry’s technological stagnation. “The market tends to choose a dominant design before it’s optimal, and it tends to under-explore.”

Taming the US defence budget

Filed under: Bureaucracy, Economics, Military, USA — Tags: , , , , — Nicholas @ 07:29

The US government is in a financial bind — that’s not exactly news. What is new, however, is that the military may actually have to take cuts, not just smaller increases in the annual budget:

On one side of the argument are fiscal hawks like Rand Paul, newly elected senator from Kentucky, who fear that a national debt heading towards 100% of GDP by the end of the decade is in itself a menace to the nation and defence must take its share of the pain. The sheer size of America’s defence budget puts it in the crosshairs. At around $700 billion a year including war expenditures, it as big as those of the world’s next 20 highest military spenders combined. Last year American defence spending exceeded the average spent during the cold-war years by 50% (adjusted for inflation), while in the past 10 years it has grown by 67% in real terms.

[. . .]

Mr Gates, a canny operator whom Barack Obama retained after he took over from George Bush, began to sniff which way the wind was likely to turn in 2008. He calculated that if he took the initiative, he might stave off deeper and more unwelcome cuts. So he curbed or cancelled more than 30 weapons systems including the army’s Future Combat System, the F-22 Stealth fighter, two missile defence systems and the Zumwalt-class destroyer. Last year he went further, proposing the closure of the Joint Forces Command in Virginia and a 10% reduction in the budget for contract workers for each of the next three years. He asked the armed services to find at least $100 billion worth of “efficiency savings” over the next five years, which he promised to reinvest in other programmes.

[. . .]

Buck McKeon, the Republican who now leads the House Armed Services Committee, has responded with predictable fury to the Gates plan, saying it was “a dramatic shift for a nation at war and a dangerous signal from the commander-in-chief”. Mr Gates can take some comfort from the fact there has been at least as much “incoming” from critics who say he has not gone nearly far enough. They point out that what is being planned is not so much a cut as a small reduction on what the Pentagon had been planning to spend over the next four to five years. The budget will still creep up in real terms until it flattens off in 2015. Given his intention to retire from office later this year, Mr Gates may not have the stomach for attempting anything more radical on his watch.

No more manned fighters?

Filed under: Military, Technology, USA — Tags: , , , , , , , — Nicholas @ 12:24

As I said the last time this topic came up, “This is not a repost from 1957”. We may actually be looking at the last generation of manned fighters, if this update from Strategy Page is true:

On February 4th, the U.S. Navy X-47B UCAV (unmanned combat air vehicle) made its first flight. It was three years ago that the navy rolled out its first combat UAV; the 15 ton X-47B. This pilotless aircraft has a wingspan of 20 meters/62 feet (whose outer 5 meter/15 foot portions fold up to save space on the carrier). It carries a two ton payload and will be able to stay in the air for twelve hours. The U.S. is far ahead of other nations in UCAV development, and this is energizing activity in Russia, Europe and China to develop similar aircraft.

[. . .]

All of these aircraft are stealthy and can operate completely on their own (including landing and takeoff, under software control). The UCAVs would be used for dangerous missions, like destroying enemy air defenses, and reconnaissance. Even air force commanders are eager to turn over SEAD (Suppression of Enemy Air Defenses) missions to UAVs. SEAD is the most dangerous mission for combat pilots. But until quite recently, all these projects had either been cancelled, or were headed in that direction.

Now, the U.S. Department of Defense wants the new UAV combat aircraft in service by the end of the decade, some twenty years ahead of a schedule that was planned in the 1990s. The F-35 is expected to cease production in 2034, more than a decade after the first combat UAVs, that can match F-35 performance, enters service.

Unable to buy new aircraft designs (because they are too expensive, or simply take too long to get into service), and facing the prospect of unmanned aircraft (UAVs) displacing more and more manned ones, the American military is spending a growing chunk of its budgets on upgrading and refurbishing the combat aircraft they already have. This was not a deliberate, long term plan, but simply a reaction to shortages of new aircraft. A lot of the new electronics and weapons involved in these upgrades can also equip UAV designs still in development, so such efforts are a double win.

More and more, it looks like the new 36 ton F-22 and 27 ton F-35 are the end of the road for manned fighter-bombers. Not just because the F-22 and F-35 cost so much to develop, but because so much new tech has arrived on the scene that it simply makes more military, and economic, sense to go with unmanned aircraft. Meanwhile, the existing F-15s, F-16s, F-18s, A-10s and all American heavy bombers are being equipped with new targeting pods and combat Internet connections, along with new radars and all sorts of electronics. Older aircraft are having worn out structural components rebuilt or replaced. This buys time until the unmanned aircraft are ready. F-35s will also fill the gap, which may be a very small one.

Usual caveats apply of course, and you could do worse than reading the comment thread on that original post for some of the caveats spelled out.

Royal Navy to withdraw patrol from Caribbean

Filed under: Americas, Britain, Military — Tags: , , , , — Nicholas @ 00:01

The funding crisis for Britain’s Royal Navy is reported to be the reason for the cancellation of patrols in and around British dependencies in the West Indies:

Britain is to abandon its warship patrols of the Caribbean for the first time since the second world war because of the navy’s funding crisis, the Guardian has learned.

The withdrawal means the navy will no longer provide a warship for anti-narcotic operations in the region, and will have to reduce its role in disaster relief work.

The decision to stop the patrols, which is expected to be confirmed on Tuesday, comes at an embarrassing time for the Ministry of Defence — a documentary series on operations undertaken by the destroyer HMS Manchester in the Caribbean is due to start tonight. The programme on Channel Five follows the ship and crew throughout its seven month deployment last year.

X-47B takes flight, Navy pilots feeling threatened

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 08:46

Lewis Page looks forward to the day US Navy aircraft carriers don’t have pilots cluttering up the works:

The disappearance of swaggering pilots from the flight decks of US naval aircraft carriers came a step closer on Friday with the first flight of the X-47B robot tailhook stealth jet.

The X-47B is intended to demonstrate that unmanned aircraft can take off from aircraft carrier catapults and land back on deck again using tailhook and arrester wires. Such arrested landings have long been regarded as one of the most difficult and dangerous feats for human pilots to master, and US naval aviators tend to measure their manhood (or occasionally these days, womanhood) by the number of “traps” in their logbook.

Not content with automating the Top Guns out of their main trick, the X-47B is also intended to demonstrate autonomous air-to-air refuelling. This is another vital trick which human pilots find quite difficult (the act of flying the probe of the to-be-fuelled aircraft into the basket trailing at the end of the tanker plane’s hose is traditionally described as being of similar difficulty to “taking a running fuck at a rolling doughnut”).

US repositioning military forces near Egypt

Filed under: Middle East, Military, USA — Tags: , , — Nicholas @ 09:58

It should come as no surprise that the American government is changing the location and composition of forces around Egypt, as the situation becomes more volatile. Both US Navy and USMC units are involved in the moves. According to the L.A. Times, the USS Kearsarge is a key part of the redeployment:

The Pentagon is moving U.S. warships and other military assets to make sure it is prepared in case evacuation of U.S. citizens from Egypt becomes necessary, officials said Friday.

The Kearsarge, an amphibious assault ship carrying 700 to 800 troops from the 26th Marine Expeditionary Unit, and the Ponce have arrived in the Red Sea, putting them off Egypt’s shores in case the situation worsens.

Pentagon officials emphasized that military intervention in Egypt was not being contemplated and that the warships were being moved only for contingency purposes in case evacuations became necessary.

Business Insider reports that USMC units are being moved now:

A senior member of the US Marine corps is telling people “multiple platoons” are deploying to Egypt, a source tells us.

There is a system within the US Marines that alerts the immediate families of high-ranking marines when their marine will soon be deployed to an emergency situation where they will not be able to talk to their spouses or families.

That alert just went out, says our source.

For those of you not steeped in military jargon, a “platoon” is a small tactical unit of about 40 men, commanded by a lieutenant. This is not an “invasion force” sized move.

US Navy’s “pee antenna”

Filed under: Military, Technology, USA — Tags: , — Nicholas @ 08:46

Warships have been sprouting more and more antennae for all the various communication equipment on board — more every year, as new devices are rolled out of development and into active service. This creates problems, especially with smaller vessels, as the multiple antennae need to be spaced far enough apart to avoid mutual interference with signals. The US Navy may have come up with a liquid solution:

With an $80 water pump, a $15 rubber hose and a $20 electrical device called a current probe that was easily plugged into a hand-held radio, [Daniel Tam] produced a spout roughly four metres tall from the waters of San Diego Bay. With this he could send and receive a clear signal. Over the intervening years his invention, dubbed the “pee antenna” by incredulous colleagues, has been tweaked and improved to the point where it can transmit over a distance of more than 50km (30 miles).

To make a seawater antenna, the current probe (an electrical coil roughly the size and shape of a large doughnut) is attached to a radio’s antenna jack. When salt water is squirted through the hole in the middle of the probe, signals are transferred to the water stream by electromagnetic induction. The aerial can be adjusted to the frequency of those signals by lengthening or shortening the spout. To fashion antennae for short-wave radio, for example, spouts between 18 and 24 metres high are about right. To increase bandwidth, and thus transmit more data, such as a video, all you need do is thicken the spout. And the system is economical. The probe consumes less electricity than three incandescent desk lamps.

A warship’s metal antennae, which often weigh more than 3½ tonnes apiece, can be damaged in storms or combat. Seawater antennae, whose components weigh next to nothing and are easily stowable, could provide handy backups — and, eventually, more than backups. Not all of a ship’s antennae are used at once, so the spouts could be adjusted continuously to obtain the types needed at a given moment. According to SPAWAR, ten such antennae could replace 80 copper ones.

The increasing cost of fighting pirates

Filed under: Africa, Middle East, Military — Tags: , , , , — Nicholas @ 11:51

Far from solving the problem of piracy in the Indian Ocean, the costs have increased dramatically:

The Somali piracy problem is not going away, despite years of efforts by an every-growing international anti-piracy patrol off the East African coast and the Indian Ocean. Since 2005, the average ship (and crew) ransom has increased over ten times (from $150,000). Thus overall cost of Somali piracy has increased to more than $5 billion a year. Most of the cost is from addition expenses for ships staying at sea longer as they avoid going anywhere near Somalia. This has cost Egypt over 20 percent of the traffic through the Suez canal, which amounts to over a billion dollars a year in lost revenue. The anti-piracy patrol costs nearly a billion dollars a year, but most of the extra costs hit the shipping companies, and their customers, who pay more for ships spending more time at sea, or the expense of additional security measures.

The problem is that piracy is a gamble, but a better gamble than anything else on offer for would-be pirates. A small vessel, a crew willing to fight, and some inexpensive weapons can be translated into a multi-million dollar jackpot. International navies on patrol rarely do more than scare off attempts, so the risk to the pirates is still low even when a patrol is in the area. Given the situation on land, it is logical for pirates to continue attacking ships passing the Somali coastline.

Last year’s biggest military developments

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 09:37

Strategy Page lists some of the most significant military developments of 2010:

* Infantry. Here we saw more evolution, not revolution, in infantry gear. But at least the trends continued to move in the right direction. The biggest change is the equipment that must be carried. Until the 1980s, you could strip down (for actual fighting) to your helmet, weapon (assault rifle and knife), ammo (hanging from webbing on your chest, along with grenades), canteen and first aid kit (on your belt) and your combat uniform. Total load was 13-14 kg (about 30 pounds). You could move freely, and quickly, like this, and you quickly found that speed and agility was a lifesaver in combat. But now the minimum load carried is twice as much (27 kg), and, worse yet, more restrictive. Over the last seven years, this has translated into some dramatic changes in training. In Iraq, troops found they were not in the best condition to run around with all that weight. This was worse in Afghanistan, with all those hills. Plus, the vest constricted movement, and that took time to adjust to. Commanders complained about troops not being properly trained, and that led to a series of changes in basic and unit training. The big change in basic was to condition troops to handle the heavy weights they would be carrying, for extended periods of time. This was particularly critical for non-combat troops (especially those operating convoys) outside of camps (where you usually didn’t have to wear armor and combat gear.) New exercises were developed. Infantry troops got several months of additional training after basic, and had plenty of opportunity to adjust to moving around wearing 14 kg or more of gear. The heavier weight included better armor and equipment (night vision, personal radio, weapon sights), which reduced combat deaths, and made the troops more lethal. But now the troops accept the fact that a lot of essential training takes place in the gym, particularly the weight room. The army and marines have been developing lighter and more comfortable versions of essential gear, but there’s still a need for muscle. This decade of infantry innovation has been noted by other armies around the world, and they are all hustling to emulate this American revolution. Not just to get the gadgets, but to implement the new training methods as well.

* Support. Few pay attention to support functions, especially no one in the media. But here is where big things happen. One of things has been how video games joined the army. Over the last eight years, billions of dollars has been spent on creating several generations of increasingly accurate combat simulators for training troops to deal with roadside bombs, hostile civilians, flying UAVs and new enemy tactics. These sims are taken for granted inside the army and marines, but still seem out of place to ill informed outsiders.

* Naval Power. The U.S. Navy has accepted the fact that is has gotten smaller, and that this process will continue. The navy shrunk by 20 percent in the last decade, to a force of 280 ships. The main reason is the high cost of new ships, to replace those that are wearing out and being retired. In the next decade, the fleet is expected to shrink another 20 percent, again because Congress refuses to provide enough money to replace older ships (only about $14 billion a year, at most, is provided for new ships, and this is expected to shrink.) New ships cost, on average, $2.5 billion each. This is made possible because of six billion dollar destroyers, seven billion dollar subs and eleven billion dollar carriers. This is offset somewhat by $1.7 billion amphibious ships and half billion dollar LCS (a compact, controversial, ship design). The big news is that the admirals are actively brainstorming how to live with a high cost/low income future, not try to magically make it go away.
