The high cost of modern combat aircraft

Filed under: Cancon, Military, Technology — Tags: , , — Nicholas @ 11:35

Many claims have been made about the actual cost to Canada for the small tranche of F-35 aircraft the Conservative government has agreed to buy. The opposition claimed that there were potentially huge savings from having a competition instead of ordering F-35’s. This may or may not be true, especially as the Department of National Defence still hasn’t made a clear statement about what role the new aircraft will be expected to fill (that is, we’re told the F-35 is the answer, but the question still hasn’t been specified).

Back when we bought the F-18, for example, one of the stated criteria was that the plane we bought had to have two engines, due to the potential risk of engine failure in the far north (where airfields are very few and very far apart). This ruled out the F-16, a single-engine plane. This time around, we’re buying a single-engine plane, but the reasons have not been spelled out. It may well be that the F-35 really is everything we need, but it does feel like we’re buying it because we were part of the original “team” during the early design phases.

Combat aircraft are not cheap, and the currently available crop show that well:

Despite the high expense all the electronic gear, the F-18G is not the most expensive combat aircraft out there. The F-22 costs $355 million each. The low budget F-18E costs $94 million each, while the F-18G goes for $105 million. The F-35 costs over $130 million (and growing). Even unmanned aircraft are pricy, with the Global Hawk costing $182 million each (with high end sensors). Older fighters, like the F-16, cost $60 million, and an F-15E goes for about $100 million. The price of the export EA-18G hasn’t been set yet, but it will probably be under $100 million.

These prices constantly fluctuate because of the need to incorporate a share of the development cost for each aircraft built. While most development expense occurs before mass production begins, there is sometimes considerable additional development expense, or major refurbishment, later in the lifetime of an aircraft. Many modern warplanes cost more than most warships, and have the same high maintenance (periodic refurbishment and development of new components) expenses.

Update: There’s another Strategy Page article of interest, this one talking about the decline of Canadian air power:

When the Canadian government decided to send some warplanes to assist in establishing the no-fly zone over Libya, they found out that sending six of their CF-18 fighters would amount to 20 percent of flyable Canadian fighters. That was a bit shocking to most Canadians. But not to those who run the Canadian Air Force, as they know quite well that the CF-18 is on the way out. For example, late last year, Canada awarded $700 million in contracts to two commercial firms (Harris and L3) to provide maintenance for its F-18 fleet of jet fighters over the next nine years. This type of contract is increasingly popular, as they provide a cheaper way to provide all the more complex maintenance, other than what the ground crews do on a daily basis. This involves major overhauls, management of spare parts and upgrades of equipment. This includes the airframe, engines and electronics. Canada expects to retire its remaining 79 CF-18s by 2020, and replace them with 65 F-35s. Meanwhile, only about 30 CF-18s are flyable, because so many aircraft are undergoing upgrades and extended maintenance.

[. . .] Canada plans to replace its CF-18s with the new 65 F-35s. The trend towards fewer, but more capable and expensive aircraft is a common one. Half a century ago, Canada had a fleet of nearly 600 fighters, including license built U.S. F-86s, and what would eventually amount to over 600 CF-100 fighters, the only Canadian designed fighter to enter mass production. The CF-100s were gradually retired over the next three decades. The last ones left service as the CF-18 entered service. But in between, Canada built, under license, several other U.S. fighter designs. Canada had become a major aircraft manufacturer during World War II (over 16,000 aircraft produced), and that provided the foundation for an aircraft industry that remains a major supplier of commercial aircraft to this day.

Why the F-22 was not deployed to Libya

Filed under: Africa, Military, Technology, USA — Tags: , , — Nicholas @ 11:12

I thought the answer to that question was simple: the F-22 is a pure fighter, and there’s no crying need for pure fighters to enforce the no-fly zone that can’t be met with older aircraft. Apparently, it’s a bit more complicated:

Conspicuously absent in the skies over Libya is the new American F-22. Despite modifying the F-22 to operate as a fighter-bomber, the F-22 was uniquely unsuited to operate as part of the international force assigned to stop Libya from attacking its own people. That job requires aircraft that can carry lots of smart bombs. Defeating the Libyan Air Force was not a major chore, and was easily handled by less capable (and cheaper to operate) air superiority fighters. Another problem was communications. The F-22 is not equipped to operate as part of an international aerial armada. The F-22 is a stealthy lone-wolf. Most of the time, the F-22 does not use its radio. To communicate with other F-22s, a special, short-range system is used. The F-22 does not have the full suite of communications equipment most NATO warplanes carry.

[. . .]

The 36 ton F-22 has internal bomb bays, like the F-117, to enhance stealthiness. Thus it can carry two half ton smart bombs, or eight 250 pound SDBs (ground penetrating Small Diameter Bombs) internally, in addition to a pair of air-to-air missiles. However, the F-22 is not yet modified to carry the SDB. The internal bays were originally designed to carry six air-to-air missiles, not bombs. Using the external hard points, which makes the aircraft more visible on radar, an F-22 can carry about four tons of bombs and missiles.

The F-22 has the most advanced radar and electronic warfare gear of any jet fighter. When you include the cost of research and development, each F-22 ends up costing nearly $400 million. But for pilots in certain types of combat, it’s money well spent. But not for what was needed over Libya, where most non-stealthy fighters can carry four or more tons of bombs and missiles.

Erasing your (digital) past

Eric Schmidt, former CEO of Google said: “I don’t believe society understands what happens when everything is available, knowable, and recorded by everyone all the time.” Privacy is dying, if not already clinically dead, in the online world. If you really want (or need) to airbrush yourself out of the picture, here are some suggestions on how to go about doing it.

The Internet has made our world a lot smaller. It has also made our histories a lot better-catalogued and more-searchable, and those developments — coupled with the weird phenomenon that people’s common sense tends to fly out the window when it comes to posting information and pictures — aren’t always beneficial to us.

Instead of popping you into a Witness Protection program — or changing your name — let us show you five steps on how to disappear from the Internet.

Step 1: Know Thine Enemy

Before you take any action, you need to know what you’re trying to get rid of. So first, do a search for your name — don’t just search Google, though, search online people search aggregation sites such as ZabaSearch, Intelius, Pipl, and Spokeo.

The evolution of news to sensational entertainment is complete

Filed under: Health, Media, Technology — Tags: , , , , , — Nicholas @ 08:27

Andrew Orlowski gives the media a damn good whacking over their deliberate panic-mongering:

Sensationalism has always been part of the popular media — but Fukushima is a telling and troubling sign of how much the media has changed in fifty years: from an era of scientific optimism to one where it inhabits a world of fantasy — creating a real-time Hollywood disaster movie with a moralising, chivvying message.

Not so long ago, the professionals showed all the deferential, forelock-tugging paternalism of the dept of “Keep Calm And Carry On”. That era lasted into the 1960s. Now the driving force is the notion that “We’re all DOOMED — and it’s ALL OUR FAULT” that marks almost every news bulletin. Health and environment correspondents will rarely be found debunking the claims they receive in press releases from lobby groups — the drama of catastrophe is too alluring. Fukushima has been the big one.

The Fukushima situation has yet to cause any measurable radiological health effects, and workers at the site were far less hard hit by the quake, tsunami and related events than just about anyone in the disaster zone, but nonetheless the nuclear story rapidly eclipsed the tens of thousands killed directly by the quake. TV’s reaction to the crisis shows how at odds it is with a more rational audience, those who know something about radiation, its consequences, and the human body’s capacity to absorb it and recover from it. The crisis for the media is that thanks to the internet, we can now all bypass these conduits for superstition and stupidity.

Thousands of people died in the earthquake and tsunami (28,000 at last report), yet the media coverage has been unrelentingly focused on Fukushima (where there have been no radiation-linked deaths so far). Surely things like this are scary enough to get equal coverage:

H/T to wormme for the link.

Update: Brendan O’Neill finds a perfect example of journalism:

In a post on the Channel 4 News website, Jon Snow, newsreader, Twitterer, cyclist and “pinko liberal” (his words), unwittingly captures the narcissism and ignorance that are fuelling Western fears over the Fukushima nuclear plant. Never mind the 20,000 who have died and the 200,000 who have been made homeless as a result of the tsunami — what Snow wants to know is what will become of the “dumping of radioactive material in sea water off Japan”.

“When will it pitch up off Cornwall?,” he asks. “Never? Do we know? Will it cause cancers? Will it kill eventually?” Perhaps he has a holiday home in Cornwall, in which case he might possibly be forgiven for thinking that the burning issue of Japan’s monumental tragedy is what impact it will have in St Ives.

Snow’s attempt to justify his navel-gazing obsession with the troubles at Fukushima (apparently he can’t get it out of his mind) is telling. Media coverage of the damaged nuclear plant has understandably “overwhelmed the continuing awfulness of the consequences of the natural disaster itself”, he says, because the natural disaster is “somehow more determinable than the unseen, unknown quantity of danger residing in the reactors, or outside them, in Fukushima”. In short, the natural disaster is too much of a done deal, a proven fact, whereas something far more tantalising lurks within Fukushima: dark, mysterious dangers, uncertainties, swirling unknowns that could unleash their fury at any moment against the unsuspecting Japanese and even us Brits.

Amazon’s “Cloud Drive” announcement

Filed under: Media, Technology — Tags: , , — Nicholas @ 08:17

Tired of moving your music from machine to machine? Feel constricted in your choices? Amazon.com thinks they’ve got an offering you won’t turn down:

Amazon.com, Inc. (NASDAQ:AMZN) today announced the launch of Amazon Cloud Drive (www.amazon.com/clouddrive), Amazon Cloud Player for Web (www.amazon.com/cloudplayer) and Amazon Cloud Player for Android (www.amazon.com/cloudplayerandroid). Together, these services enable customers to securely store music in the cloudand play it on any Android phone, Android tablet, Mac or PC, wherever they are. Customers can easily upload their music library to Amazon Cloud Drive and can save any new Amazon MP3 purchases directly to their Amazon Cloud Drive for free.

“We’re excited to take this leap forward in the digital experience,” said Bill Carr, vice president of Movies and Music at Amazon. “The launch of Cloud Drive, Cloud Player for Web and Cloud Player for Android eliminates the need for constant software updates as well as the use of thumb drives and cables to move and manage music.”

“Our customers have told us they don’t want to download music to their work computers or phones because they find it hard to move music around to different devices,” Carr said. “Now, whether at work, home, or on the go, customers can buy music from Amazon MP3, store it in the cloud and play it anywhere.”

Don’t get too excited, fellow Canadians: this is the .com company, not the .ca flavour. Since amazon.ca still can’t sell you MP3 tracks, I doubt that the Amazon Cloud will be available north of the border any time soon.

TEPCO still seems to be more a hindrance than a help over Fukushima

Filed under: Bureaucracy, Japan, Technology — Tags: , , — Nicholas @ 12:36

A report from Kyodo News shows that Tokyo Electric Power Co. (TEPCO) is still not fully co-operating or providing all the information needed to clean up the Fukushima reactor sites:

While efforts at containing troubled reactors have not been making rapid progress at its Fukushima Daiichi nuclear power plant, signs were emerging that Tokyo Electric Power Co., in the absence of a top officer, is losing its grip on accurately informing the public about risks from radiation.

On Sunday, the utility, known as TEPCO, announced in the morning that the concentration of radioactive materials of water found inside a turbine building adjacent to a rector housing was ”around 10 million times (that of) water in a normal reactor core” but later corrected the information, saying it ”made a wrong estimation.”

[. . .]

On March 20, TEPCO said, ”There were no increases in radiation levels in adjacent areas.” But increases were logged in various parts of adjacent areas, prompting skeptical reporters to raise a series of questions at a news conference but TEPCO officials remained mum.

TEPCO has been giving a series of news conferences since Fukushima Daiichi got into trouble after the March 11 quake. Attending officials have not been able to provide satisfactory answers to a majority of questions raised, only repeating words of apology and, ”We will check it.” It has left the impression they are unable to reply to questions because they are not given enough information.

[. . .]

But on Saturday, it was disclosed that the company had not informed workers who suffered high levels of radiation at the No. 3 reactor unit about radiation levels of the place where they would be working. The government was also found to have not been informed.

Top government spokesman Yukio Edano expressed his displeasure, telling a news conference, ”We cannot give appropriate instructions unless accurate information is provided swiftly.”

TEPCO is allowed to monopolize the power utility market in Tokyo and surrounding regions by law. As the nation’s biggest utility, it has also been the key promoter of the nuclear power policy and one of the main employers of retiring bureaucrats.

Critics say the company lacks cost consciousness and apparently has no idea about what competition is. It is more like a bureaucracy rather than a business being run, they said.

Radiation: the “Banana Equivalent Dose”

Filed under: Health, Science, Technology — Tags: — Nicholas @ 09:29

A link from wormme leads to this interesting article providing some basic information on radiation:

There is an interesting way of comparing different amounts of radiation, and we’ve now built up all the pieces to understand it. Nuclear physicists and safety engineers sometimes use a unit called the “banana equivalent dose.” This is basically how it’s calculated.

First you take a banana.

Like pretty well everything in nature, bananas are slightly radioactive. Because bananas concentrate potassium, they are more radioactive than a lot of other foods — natural potassium includes some part that is the radioactive isotope potassium-40. That means eating a banana, and thereby ingesting the potassium, adds a measurable radiation dose from the radioactive potassium-40.

Now, before you change to kumquats or something, it’s not much, and bananas aren’t the only source. Potatoes are another food that concentrates potassium. But it does mean we can usefully compare the total dose we get from a banana with other small amounts of radiation. The somewhat-joking term for this is the “banana equivalent dose,” or BED.

Okay, that’s the amusing part, but read the whole thing: it’s informative and non-sensationalized.

Part of the reason I’m posting links to articles like this is that there is a lot of misinformation on all things nuclear and the mainstream media is doing a flat-out terrible job of reporting.

I’ve lived within 10-20 km of nuclear power stations for more than a decade, and I’m not particularly worried day-to-day about the risks due to that proximity. I used to joke with visitors that we didn’t pay for electricity — the walls glowed after dark from the radioactivity. I stopped doing that when I realized people were taking me a bit more seriously than I expected.

“How does it work, then? Basically they aren’t too sure”

Filed under: Randomness, Technology — Tags: — Nicholas @ 08:52

This one sounds positively science-fictiony:

Boffins in America say they’re on the track of a backpack electro-beam forcefield device capable of snuffing out raging fires without any need for water, hoses or other traditional firefighting apparatus. Apart from portable applications, they raise the possibility that the new technology might replace building sprinkler systems with ceiling mounted conflagration-squelching zapper terminals.

“Controlling fires is an enormously difficult challenge,” says Dr Ludovico Cademartiri. “Our research has shown that by applying large electric fields we can suppress flames very rapidly. We’re very excited about the results.”

Cademartiri and his fellow boffins at Harvard uni have tested their flame-zapping gizmo in the lab, using a 600-watt amplifier hooked up to a “wand-like probe”. This setup was apparently able to snuff out test flames “more than a foot high”. The team think that it should be possible to get similar effects with a less power-hungry system using 60W or less, raising the possibility of portable equipment.

So, not quite ready to snuff out the soaring flames of a major fire, yet.

Rogers is actively throttling bandwidth for World of Warcraft players

Filed under: Cancon, Gaming, Technology — Tags: , — Nicholas @ 11:14

In what isn’t really a surprise, Justin Olivetti reports on how Canadian WoW players have been suffering from deliberate throttling:

If you play World of Warcraft in Canada and were wondering why your connection seemed a bit slow, it turns out there may be a good explanation: Rogers Communications has been deliberately throttling the game across the country.

[. . .]

Rogers said that it was Blizzard’s use of BitTorrent to deliver updates that triggered the throttling, and said that customers who disabled this setting — as well as any other peer-to-peer applications — would not see a slowdown in speed. “Rogers will engage our customers to ensure they are aware of these recommendations, while continuing to work on a longer term solution,” a spokesperson said.

Panic-mongers still hard at work over Fukushima

Filed under: Health, Japan, Media, Technology — Tags: , , — Nicholas @ 10:58

Lewis Page is less than impressed with the media’s ongoing coverage of the Fukushima reactor clean-up:

The situation at the quake- and tsunami-stricken Fukushima Daiichi nuclear powerplant in Japan was brought under control days ago. It remains the case as this is written that there have been no measurable radiological health consequences among workers at the plant or anybody else, and all indications are that this will remain the case. And yet media outlets around the world continue with desperate, increasingly hysterical and unscrupulous attempts to frame the situation as a crisis.

[. . .]

Nonetheless, in the hyper-cautious nuclear industry, any dose over 100 millisievert is likely to cause bosses to pull people out at least temporarily. Furthermore, the three workers had sustained slight burns to their legs as a result of standing in the radioactive water – much as one will burn one’s skin by exposing it to the rays of the sun (a tremendously powerful nuclear furnace). They didn’t even notice these burns until after completing their work. Just to be sure, however, the three were sent for medical checks.

So — basically nothing happened. Three people sustained injuries equivalent to a mild case of sunburn. But this was reported around the globe as front-page news under headlines such as “Japanese Workers Hospitalized for Excessive Radiation Exposure”. Just to reiterate: it was not excessive.

Reporters clamoured to know more — in particular how could the water in the basement of the reactor building have become so radioactive — no less than “10,000 times normal”. One might note that in general radiation levels 10,000 times normal mean that you could achieve a tiny fraction of an extra percentage point of cancer risk by being exposed for a fortnight or so.

[. . .]

Then there’s the matter of the tapwater in Tokyo. Two days ago, levels of radioactive iodine-131 were found in the city’s water which were above the safety limit for baby milk calculated on the basis of a year’s consumption: in other words, if babies drank such water for a year constantly they would have a tiny, minuscule extra risk of thyroid cancer.

[. . .]

There was never any chance whatsoever that levels of iodine-131 in the tapwater would remain noticeable for a year, which is what would be necessary for any effects at all on the city’s babies. It was really quite irresponsible of the authorities to recommend that infants shouldn’t drink it. (One can’t help noticing that the first such recommendation reportedly came from the city authorities, belatedly followed by the national government. The Tokyo city governor is from the national opposition party and is facing a tough re-election battle. He had previously sought to use the Fukushima situation to cast his political rivals in a bad light over the deployment of Tokyo’s elite Hyper Rescue firefighters.)

I’d also recommend that you keep an eye on the World’s Only Rational Man for his professional take on what the media is currently panicking over at any given moment:

If modern “journalism” wasn’t the single most incompetent industry in human history we wouldn’t be pulling our hair out over this. Where’s the followup to the reports of Cl-38?

How freakin’ incompetent is the entirety of Big Media?!

You’ve had two weeks to learn a minimum about this subject you obsessively “cover”.

“But…but math is hard!” you whine? Then find some dad-gum folks who do this crap for a living rather than cultivate ivory tower media-hounds.

Sorry. Forgive the venting. Tired and P.O.ed.

Apparently going beddy-bye to the thought of runaway nuclear excursions isn’t warm milk and happy stories. Monsters Inc. could have stayed in the scaring business if they’d taken lessons from The Media.

This blogging day began with concern about neutrons. And so it ends.

I wish we still had reporters.

Because I hate journalism.

Once again, wormme is a radiological control technician, so he actually knows what the hell he’s talking about, unlike just about everyone “covering” the news.

Over-analyzing the Bayeux Tapestry

Filed under: France, History, Humour, Technology — Tags: — Nicholas @ 10:39

Chris Mellor looks at the Bayeux Tapestry from a data storage perspective:

The Bayeux Tapestry, the victor’s view of the events, was finished in 1077, ten years after it was begun, making it 934 years old. At 224.3ft long and 1.6ft wide the total surface area is 358.88sq ft.

Our understanding is that the Tapestry features 45 to 48 threads per inch which gives us a resolution approximating 47dpi with a colour depth of 8, ignoring later repairs. Thus, in information terms, the tapestry contains 2.429MB of information, assuming 1-bit per colour, 47dpi, and a 51,678.72 square inch surface area.

From the writing point of view it took ten years for English (Saxon) seamsters, seamstresses or embroiderers to write this 2.429MB of data, which must be some kind of record. Assuming an eight-hour, 350-day working period for these ten years, that implies a write bandwidth of 10.84 bytes/hour; a spectacularly slow data rate in information transfer terms.

What makes it worse is that there were multiple parallel write heads — seamsters or seamstresses — and we could envisage a team of five on average, meaning each write head in this theoretical Bayeux Tapestry archiving model wrote at a rate of 2.168 bytes/per hour (17.344 bits/min). A truly amazingly poor information write bandwidth from our IT viewpoint, but a blur of flickering needles and fingers seen from the embroiderers’ seat.
