The American President

Filed under: Government, Military, Politics, USA — Tags: , , , — Nicholas @ 11:04

David Gewirtz has a thought about the awesome achievement of the American Presidency:

America has almost 3 million active and reserve military personnel. We spend almost $550 billion dollars each year on defense. According to the Federation of American Scientists, America has just about 5,000 nuclear warheads.

The United States Navy has about 300 ships, almost 4,000 aircraft, 71 submarines, and 11 aircraft carriers — each with more firepower than most nations. The United States has close to 9,000 battle-ready tanks. The United States Air Force has nearly 6,000 aircraft, 450 intercontinental ballistic missiles, and 32 satellites orbiting Earth under its direct control.

In other words, the United States has the most powerful military in the history of mankind.

And yet, every four to eight years, ultimate control of that incredible firepower changes hands — without a single shot being fired.

F-35 delays mean extended life for the F-16

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 08:14

Strategy Page looks at the F-16, the “cheap and cheerful” alternative for many countries who are watching and waiting as the F-35 program staggers on.

Many air forces are finding that it’s more cost-effective to upgrade via new electronics and missiles and, as needed, refurbishing engines and airframes on elderly existing fighters, rather than buying new aircraft. This is especially the case if the new electronics enable the use of smart bombs. One of the more frequently upgraded older fighters is the American F-16. Even the U.S. Air Force, the first and still largest user of F-16s is doing this with some of its F-16s.

The U.S. Air Force is currently refurbishing several hundred of its 22 ton F-16 fighters, because their replacement, the 31 ton F-35 is not arriving in time. This is the same reason for many nations to upgrade their F-16s. Some of these nations are holding off on ordering F-35s (or cancelling existing orders), either because of the high price or doubts about how good it will be. Aircraft manufacturing and maintenance companies see a huge market for such upgrades. Half or more of the 3,000 F-16s currently in service could be refurbished and upgraded to one degree or another. That’s over $25 billion in business over the next decade or so.

The F-35 began development in the 1990s and was supposed to enter service in 2011. That has since slipped to 2017, or the end of the decade, depending on who you believe. Whichever date proves accurate, many F-16 users have a problem. Their F-16s are old, and by 2016 many will be too old to operate. Some other nations have even older F-16s in service.

[. . .]

Although the F-35 is designed to replace the F-16, many current users will probably keep their F-16s in service for a decade or more. The F-16 gets the job done, reliably and inexpensively. Why pay more for new F-35s if your potential enemies can be deterred with F-16s. This becomes even more likely as the F-35 is delayed again and again. Finally, the upgrade is a lot cheaper, costing less than $20 million, compared to over $100 million for a new F-35. If your potential enemies aren’t upgrading to something like that, a refurbed F-16 will do.

Tracking (smaller) space junk in orbit

Filed under: Space, Technology, USA — Tags: , , , — Nicholas @ 11:04

Strategy Page on the latest developments in tracking even smaller pieces of space junk in orbit around the Earth:

The U.S. Air Force is spending nearly $4 billion to build a S-Band radar on Kwajalein Island in the Pacific. This will make it easier and cheaper to find and track small (down to 10mm/.4 inch) objects in orbit around the planet. Such small objects are a growing threat and Space Fence will make it possible to track some 300,000 10mm and larger objects in orbit.

Getting hit by an object 100mm (4 inch wide), if it’s coming from the opposite direction in orbit, results in an explosion equivalent to 20 kg (66 pounds) of TNT. That’s all because of the high speed (7 kilometers a second, versus one kilometers a second for high-powered rifles) of objects in orbit. Even a 10mm object hits with the impact of 50-60 g (2 ounces) of explosives. In the last 16 years eight space satellites have been destroyed by collisions with one of the 300,000 lethal (10mm or larger) bits of space junk that are in orbit. As more satellites are launched more bits of space junk are left in orbit. Based on that, and past experience, it’s predicted that ten more satellites will be destroyed by space junk in the next five years. Manned space missions are at risk as well. Three years ago a U.S. Space Shuttle mission to fix the Hubble space telescope faced a one in 229 chance of getting hit with space junk (that would have likely damaged the shuttle and required a backup shuttle be sent up to rescue the crew). Smaller, more numerous, bits of space junk are more of a danger to astronauts (in space suits) working outside. The shuttle crew working outside to repair the Hubble satellite had a much lower chance of being killed by space junk because a man in a space suit is much smaller and the space suits are designed to help the person inside survive a strike by a microscopic piece of space junk.

Unthinking support of “the troops”

Filed under: Media, Military, Politics — Tags: , , , , — Nicholas @ 10:22

If you’ve read the blog for a while, you’ll know that I’m far from anti-military. I was in the Canadian militia (the army reserve) during my teenage years, and still have friends who are serving in the armed forces of Canada, Britain, and the US. Since 2001, Canadians in particular have re-evaluated their views of the military and are now much more likely to demonstrate their support for the army, the Royal Canadian Navy, and the Royal Canadian Air Force. Even so, Canadians are much more low-key in their demonstrations of respect and approval than Americans are.

Some of the more outspoken supporters actually give me the creeps … rather than showing their support for the soldiers, sailors, and airmen, they seem to be showing their support for militarism. That sort of thing enables and encourages military adventurism, armed intervention in other countries, and the militarization of civilian life (look at the military-style gear many police departments now operate, including drones for border surveillance and drug war operations). That’s a line I never want to see Canada cross.

At the Future of Freedom Foundation blog, Jacob Hornberger expresses some of the same concern:

One of the most fascinating phenomena of our time is the extreme reverence that the American people have been taught to have for the military. Wherever you go — airports, sports events, church — there is a god-like worship of the military.

“Let us all stand and express our sincerest thanks to our troops for the wonderful service they perform for our country,” declare the sports broadcasters.

“Let us pray for the troops, especially those in harm’s way,” church ministers exhort their parishioners.

“Let us give a big hand to our troops who are traveling with us today,” exclaim airline officials.

Every time I see this reverence for the military being expressed, I wonder if people ever give any thought to what exactly the troops are doing. No one seems to ask that question. It just doesn’t seem to matter. The assumption is that whatever the troops are doing, they are protecting our “rights and freedoms.” As one sports broadcaster I recently heard put it, “We wouldn’t be here playing this game if it weren’t for the troops.”

There is at least one big problem with this phenomenon, however: The troops are engaged in actions that are harmful to the American people, including most of the people who have a reverential attitude toward them.

The real defence debate (that isn’t happening in the election campaign)

Filed under: Government, Military, USA — Tags: , , , , — Nicholas @ 14:00

Scott Rasmussen outlines the stark contrast between how ordinary Americans feel about their country’s defence establishment and how the politicians they elect fail to reflect those feelings:

As a starting point, Americans are proud of their country and hold its armed forces in high regard. Seventy-nine percent would rather live here than anywhere else, and at a time of deep cynicism about large institutions 81 percent have a favorable opinion of the U.S. military.

Yet this respect and admiration for the troops co-exists with doubts about the jobs they’ve been asked to do. Most voters now believe it was a mistake for the U.S. to have gotten involved in Iraq, and most now want to see troops brought home quickly from Afghanistan. Support for the military action in Libya peaked at 20 percent.

Americans are also in a mood to dramatically reduce our security guarantees for other nations. Less than half (49 percent) believe the U.S. should remain in its bedrock military alliance, NATO. Out of 54 countries with which Washington has signed mutual-defense treaty obligations, plus two others (Israel and Mexico) that receive our implicit backing, a majority of Americans supports defending just 12. Countries that don’t reach the 50 percent threshold include our oldest ally, France, along with Japan, Poland, and Denmark. The only four countries that 60 percent of Americans are willing to defend are Canada, the United Kingdom, Australia, and Israel.

These findings highlight the central 21st-century gap between the citizenry and its political class. Three out of four Americans believe U.S. troops should never be deployed for military action overseas unless vital national security interests are at stake. Yet the last several presidents have adopted far less restrictive criteria for sending troops abroad. The military is often dispatched for humanitarian purposes or in the belief that the U.S. should police the world, but only 11 percent of voters believe Uncle Sam should play global cop.

US military faces recruiting nightmare

Filed under: Health, Military, USA — Tags: , , , , — Nicholas @ 09:17

Strategy Page outlines the most recent major problem the US military is facing: the bloat of potential recruits (not in numbers, but in individual mass). While the number of new recruits needed is declining, the pool of potential recruits to draw from has been declining even faster:

The problem is that Americans have, in the last two decades, become very fat and out-of-shape. There are 32 million male Americans of prime military age (17-24). But because of bad lifestyle choices, only 13 percent of them (4.2 million) are physically eligible for service. Each year, the armed forces have to recruit 150,000 new troops. The military is allowed to waive some physical or mental standards, and this means that only about 20 percent of those 32 million potential recruits qualify. Each year, recruiters have to convince about two percent of those eligible that they should join up. It’s a tough job, made worse by a generation that eats too much, exercises too little and doesn’t pay enough attention in school. You not only have to be physically fit enough to join, you also have to be smart enough and have no criminal record.

The enormous growth in computer entertainment, and subsequent massive reduction in exercise teenage boys get is the major reason for the body fat percentage crisis. As a result, one of the biggest problems American military recruiters have is unfit young Americans trying to enlist. Some 57 percent of potential recruits are not eligible because they do not score high enough on the aptitude test the military uses to see if people have enough education and mental skills to handle military life. Many of those who score too low do so because they did not do well at school. A lot of these folks have high IQs, but low motivation. Most of the remainder are not eligible for physical reasons. But get this; the most common physical disqualifier is being overweight. Nearly a third of the people of military age are considered obese. Many of these big folks are eager to join, and are told how much weight they have to lose before they can enlist. Few return light enough to sign up.

Computer gaming and other forms of indoor entertainment certainly bear some of the blame for the obesity problem, but other issues should also be included: helicopter parents who don’t dare let their kids go outside to play without full-time parental supervision, schools that have reduced or eliminated physical education for budget or liability reasons, and the huge increase in availability of low-priced, high-calorie fast foods.

F-22 air supply problem found (perhaps)

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 08:18

The F-22 fleet has been plagued by a mysterious air supply problem for more than a year. Strategy Page reports on what might be the solution:

The U.S. Air Force has concluded (for the moment) that the cause of the breathing problems F-22 pilots were having were caused by a defective valve on the special vests pilots wear to help them with their breathing in the low pressure of the F-22 cockpit. The vests are not being used until modifications can be made to fix the problem.

Earlier this year the vests came under suspicion because it appeared that they automatically inflated too much during high-g (gravitational force) maneuvers, making it difficult for pilots to breathe. This would be subtle, so that the pilot would not immediately notice a problem with breathing. Anything obvious would have been noticed when the vest was tested. Pilots have complained about a “strange feeling” when breathing with the vest during high-g turns but not in such a way that they connected it with the disorientation. Further examination discovered that the vest was indeed inflating when it should not have been, and causing breathing problems. The air force will make a few other tweaks to the pilot air supply system and quietly hope that the problem is indeed solved.

[. . .]

Now the air force can drop a number of precautionary restrictions imposed over the last year. For example, pilots were forced to make flights at least 24 hours apart. In training, and combat, pilots would take their F-22s up two or more times a day. The theory was that the pressure vests and acceleration atelectasis would not be a problem if pilots have at least 24 hours to recover.

Despite the breathing problems the air force continued to fly its F-22s. The decision to keep flying was made because the air supply problems had not killed anyone yet and they were rare (once every 10,000 sorties). The 14 incidents that did occur were all cases of F-22 pilots apparently experiencing problems. The term “apparently” is appropriate because the pilots did not black out and a thorough check of the air supply system and the aircraft found nothing wrong.

Here’s the initial discussion of the problem from July last year. In September, the F-22s were cleared to fly again, but they were grounded again in October.

US admiral calls for more “trucks” and fewer “limousines”

Filed under: Military, Technology, USA — Tags: , , , , — Nicholas @ 09:06

The Economist reports on a recent article in the US Naval Institute’s Proceedings by Admiral Jonathan Greenert, chief of naval operations:

The “luxury-car” platforms designed in the last days of the cold war (and which still dominate much military procurement) have not adapted well to changes in security and technology, he says. Such platforms must always carry the sophisticated equipment to defeat a sophisticated foe. Yet much of this may be irrelevant to the navy’s typical missions in the past 20 years: counter-terrorism, anti-piracy, mine-clearing, maritime patrolling and carrier operations in support of counter-insurgency campaigns in Iraq and Afghanistan.

Given the cost of building new platforms and the need to keep them in service for 30 to 50 years or even longer, Admiral Greenert wants them to be more like “trucks”: with plenty of space and power to accommodate different payloads. Some of the Pentagon’s oldest platforms have turned out to be much better trucks than their successors.

Because of its sheer size, its reserve electrical power and its small number of integral systems, at least compared with newer aircraft-carriers, the 50-year-old USS Enterprise has proved more adaptable than modern, densely packed designs. Unlike them, it has the space, storage and power-generating capacity to carry new aircraft types and new systems.

The same is true of the stalwart B-52 bomber. It first flew 60 years ago. It is now expected to stay in service until 2045. Conceived as a strategic bomber after the second world war, it has been recast many times. It is now proving to be a cost-effective platform for the latest precision-guided “stand-off” weapons (meaning those fired from afar). It is also more dependable than any of its more advanced successors.

Another advantage of high-tech payloads over platforms stems from Moore’s law: the doubling of computer-chip speed every two years or less. This embarrasses military planners. Even their latest and fabulously expensive equipment often lacks the processing power of cheap consumer gadgets. It takes at least 15 years to bring a new ship or aircraft from design to completion. That can be eight or more cycles of Moore’s law.

The F-35 is “unaffordable and simply unacceptable”

Filed under: Military, Technology, USA — Tags: , , , , — Nicholas @ 12:46

Winslow Wheeler on the near-doubling of the F-35 price (so far):

On June 14 — Flag Day, of all days — the Government Accountability Office released a new oversight report on the F-35: Joint Strike Fighter: DOD Actions Needed to Further Enhance Restructuring and Address Affordability Risks. As usual, it contained some important information on growing costs and other problems. Also as usual, the press covered the new report, albeit a bit sparsely.

Fresh bad news on the F-35 has apparently become so routine that the fundamental problems in the program are plowed right over. One gets the impression, especially from GAO’s own title to its report, that we should expect the bad news, make some minor adjustments, and then move on. But a deeper dive into the report offers more profound, and disturbing, bottom line.

Notorious for burying its more important findings in the body of a report — I know; I worked there for nearly a decade — GAO understates its own results on acquisition cost growth in its one-page summary, which — sadly — is probably what most read to get what they think is the bottom line.

[. . .]

Set in 2001, the total acquisition cost of the F-35 was to be $233.0 billion. Compare that to the current estimate of $395.7 billion: cost growth has been $162.7 billion, or 70%: a lot more than what GAO stated in its summary.

However, the original $233 billion was supposed to buy 2,866 aircraft, not the 2,457 currently planned: making it $162 billion, or 70%, more for 409, or 14%, fewer aircraft. Adjusting for the shrinkage in the fleet, I calculate the cost growth for a fleet of 2,457 aircraft to be $190.8 billion, or 93%.

The cost of the program has almost doubled over the original baseline; it is not an increase of 42%.

Don’t expect Korean re-unification to follow the German script of the 1990s

Filed under: Asia, China, Japan, Media, Military — Tags: , , , , , , — Nicholas @ 09:03

Some potentially chilling geo-strategic news from China:

The government has had reports issued denying American and Japanese studies of the rapid expansion of Chinese military power in the last decade. The Chinese reports were issued in Chinese, English and Japanese. China’s official line is that their armed forces are only for defense and are growing at a far more modest rate than foreign analysts are claiming. The Chinese are having a hard time refuting the foreign analysts, given the availability of satellite photos and many cell phone images of new Chinese weapons. China tries to control this sort of information leak, but has been unable to do so.

Another problem for China is the fact that internal propaganda campaigns cannot be kept secret from the outside world. This was never possible, but even with a heavily censored Chinese Internet, such embarrassing news quickly gets to an international audience very quickly. The latest example of this is remarks by Chinese officials about the “Great Wall of China.” The new claims are that the wall was larger than its current official size, and incorporates parts of North Korea. This was alarming news in South Korea, which is preparing to take over North Korea when the communist dictatorship up there collapses. The collapse is expected soon. With this new “Great Wall” argument the Chinese are announcing that if the North Korean government losses control, China will reclaim some “lost provinces” and the foreigners (including South Korea, Japan and the United States) had better stay out of it.

Given the Chinese claims in the South China Sea (that is, almost all of it), it is probably no surprise to the other nations that China might also have designs on part or all of the territory of modern day North Korea. When the German Democratic Republic (aka East Germany) collapsed in the early 1990s, the Federal Republic (West Germany) was able to pick up the pieces in a relatively co-ordinated manner. China may not want South Korea doing the same thing after a North Korean collapse.

The US Air Force faces its toughest opponents: the lobbyists

Filed under: Military, Politics, Technology, USA — Tags: , , , — Nicholas @ 08:54

In a stunning outbreak of common sense, the USAF cancelled an order for an expensive UAV because it wasn’t as effective at the intended task as other methods. Battle would soon be joined with the fearsome lobbyists and their congressional minions:

Earlier this year, the U.S. Air Force cancelled existing orders for the RQ-4 Global Hawk UAV and withdrew 18 from service. The Global Hawk manufacturer (Northrop Grumman) unleashed their lobbyists and political supporters on the air force, demanding an explanation for (and reversal of) the decision. The air force responded that the RQ-4 was too expensive and the manufacturer too unreliable. Moreover, reconnaissance mission requirements had changed with the withdrawal from Iraq. High altitude, long duration missions were not needed as much. And those that were needed were better served by using the smaller and cheaper Reaper. Missions normally carried out by the RQ-4 were now handled more efficiently and cheaply by the U-2, which could carry more sensors to higher altitudes. Northrop Grumman insisted it could mount any U-2 sensors on an RQ-4. The air force replied that this had not been their experience. Northrop Grumman would offer to make modification which often went way over budget, took longer than specified and often didn’t work. The air force had been burned once too often by Northrop Grumman when it came to upgrades and fixes on the RQ-4.

[. . .]

Increasingly over the last decade, the air force and the manufacturer of the RQ-4 found themselves feuding over design, cost, and quality control issues. The latest issue was the unreliability of the new Block 30 models. This renewed Department of Defense threats to cancel the program. But Northrop Grumman lobbyists have made sure the key members of Congress knew where Global Hawk components were being built and how many jobs that added up to. While that delayed the RQ-4 Block 30 cancellation it did not stop it. The air force was placated for a while when Northrop Grumman fixed some of the problems (some of which the manufacturer said don’t exist, or didn’t matter). The Block 30 was supposed to be good to go, but the air force was not convinced and decided that Block 30 was just more broken promises. Congress was also tired of all the feuding and being caught between Northrup lobbyists and exasperated air force generals. Then there was politician’s decision to cut the defense budget over the next decade. Something had to go.

Meanwhile, the manned U-2 has continued to operate as expected and, despite its age, with predictable costs. Moreover, the U-2 carries a larger load than the RQ-4 and that means it can do more when it is up there. The U-2 also has its supporters in Congress. So the RQ-4 took a hit so the popular U-2 could keep flying for another decade or so.

[. . .]

There has been plenty of competition for RQ-4 work. In addition to the manned U-2, there is a longer (42 hours) endurance version of the five ton Reaper as well as the jet powered version of the Reaper called Avenger. This aircraft can do 85 percent of what the RQ-4 can, but costs half as much. Moreover, the Avenger is 29 percent faster, although it only has endurance of 20 hours, compared to 35 for the RQ-4. Most importantly, the Avenger and Reaper come from a manufacturer (General Atomics) that has been much more dependable than Northrop Grumman.

Speculation on the intended mission of the X-37B

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

A blog post at New Scientist compares the achievement of the Chinese space program, which just successfully placed three astronauts aboard the ISS and the highly mysterious X-37B spaceplane which just completed a 469-day mission:

China’s space agency took the plaudits for successfully docking its crewed Shenzhou-9 spacecraft with its orbiting lab Tiangong-1 today, but the feat was slightly overshadowed by the weekend landing of the US X-37B spaceplane, which after a record-breaking orbital flight of 469 days showed just how far China has to go to catch up with advanced spacefaring nations.

At around noon local time, the Beijing Aerospace Control Centre relayed live pictures of Shenzhou-9’s docking on state broadcaster China Central Television. The space capsule held off at a distance of 62 kilometres from Tiangong-1 before making its docking approach just before 2pm — and once the crew had manually locked on to the latter’s cruciform docking target it took only eight minutes to latch the spacecraft together safely.

[. . .]

This Boeing-built spaceplane, roughly one quarter the size of the space shuttle, is equally mysterious. It flies to orbit on a regular rocket and when there deploys a solar array that gives its sensors the power they need for extended missions. It also has enough propellant to fire thrusters that make small changes to its orbit in a bid to foil surveillance. The vehicle re-enters the atmosphere just like the shuttle but lands entirely autonomously, making it a space drone.

At no point has the USAF revealed the craft’s purpose: in addition to spacecraft surveillance, it could deploy a robot that repairs (or disables) satellites in orbit, say some, while at the darker end of the spectrum of possibilities — it was a DARPA project in its early days — it could carry a warhead, using its drone homing capability to provide surprise precision strike from orbit.

Bombing campaigns against Nazi Germany were remarkably inaccurate

Filed under: Britain, Europe, Germany, History, Military, WW2 — Tags: , — Nicholas @ 10:54

An article in History Today recaps the huge gap between what the RAF was thought to be accomplishing in the first half of World War 2 and what they actually achieved in the bombing campaign against Germany:

By 1941, after the winter Blitz in which the Luftwaffe had relentlessly bombed the cities of Britain, the British people wanted to know that the RAF were ‘giving it back’ to the Germans. Later that year, as [Michael] Paris describes, Harry Watt directed his film Target for Tonight for the Crown Film Unit. Made with actual RAF personnel performing a script written by Watt, Target follows the story of a single raid on an imaginary railway yard and oil depot somewhere near a bend in the Rhine. The film sought to celebrate the quiet heroics of the RAF, which is shown to have the ability to mount a precision raid with great success. Audiences no doubt cheered to see the (models of the) target ablaze and to know — or, rather, believe — that the RAF was creating havoc in the enemy’s heartland.

[. . .]

According to a secret Cabinet report, which analysed aerial photographs in the summer of 1941, the RAF failed to get even one third of its bombs within five miles of its targets. The Strategic Air Offensive was published much to the chagrin of wartime RAF leaders such as Sir Arthur ‘Bomber’ Harris and generated intense and widespread controversy.

By the 1980s it was largely accepted that, before new navigational aids were introduced in 1942, the RAF offensive had been a complete failure. Although the moral debate about the rights and wrongs of ‘area’ or ‘indiscriminate’ bombing has continued ever since, there are no serious historians today who challenge the accuracy of the Webster-Frankland account. And so, in 1990, Paris was able to point out the gulf between what the RAF pretended had been happening and what, in reality, was going on.

Before the war started, the air force always claimed that the “bomber would always get through”. What they didn’t say was that it couldn’t be predicted where the bomber would get through to.

However, it must be remembered that even the US Air Force, which carried out daylight air raids against German targets in the latter half of the war, had an accuracy issue too:

Gladwell began with the story of Carl Norden — a Swiss engineer, born in 1880, domineering and narcissistic, “who had very strong feelings about alternating current” and much else. Norden became obsessed with finding a more precise ways to deliver bombs from aircraft — and invented the Norden Mark 15 Bomb Sights. Its promise: that a bomb could be dropped into a pickle barrel from 20,000 feet.

The US military was excited; in fact, Washington spent $1.5 billion in 1940 dollars rolling out the devices, buying 90,000 of them and training 50,000 bombardiers to use them. Yet when America was brought into world war two, “it turns out they were not the holy grail”. They could only hit a pickle barrel under perfect conditions — and life is rarely perfect, it proved. They were hard to use, broke down, could not function in cloud without direct line of sight of the target, and were inaccurate. Plus, Norden had hired German engineers — who gave Berlin the complete blueprint by 1938.

The sickly Raptor spawns another concern

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 07:59

As if the F-22 hadn’t already had enough issues, there’s a new concern called the “Raptor cough” (acceleration atelectasis) showing up among F-22 pilots:

Increasingly desperate to find out what is causing its F-22 (“Raptor”) fighter pilots to get disoriented while in the air, the U.S. Air Force is now investigating what appears to be excessive coughing by F-22 pilots. It’s being called “Raptor Cough” and is actually a known condition (acceleration atelectasis) for pilots who have just completed a high speed maneuver. But it appears to be showing up more frequently among F-22 pilots. That may be the result of months of tension over the reliability and safety of the aircraft. The F-22 pilots are perplexed and a bit nervous about their expensive and highly capable jets.

The air force believes that something, as yet unknown, is getting into the pilot air supply and causing problems. Despite this, the air force continues flying its F-22s. The decision to keep flying was made because the air supply problems have not killed anyone yet and they are rare (once every 10,000 sorties).

The 14 incidents so far were all cases of F-22 pilots apparently experiencing problems. The term “apparently” is appropriate because the pilots did not black out and a thorough check of the air supply system and the aircraft found nothing wrong. There have been nearly 30 of these “dizziness or disorientation” incidents in the last four years, with only 14 of them serious enough to be called real incidents. Only one F-22 has been lost to an accident so far and, while that did involve an air supply issue, it was caused by pilot error, not equipment failure.

US Postal Service develops a lithium allergy

Filed under: Military, Technology, USA — Tags: , , , — Nicholas @ 08:34

The United States Postal Service has announced that they will no longer allow shipments that include lithium batteries, as of May 16th:

If you want to send an iPad, a Kindle Fire, an iPhone, a laptop, or a similar device overseas, now is the time to send it, because as of next week, the U.S. Postal Service will be banning all electronic gadgets that contain a lithium battery.

The reason? Those lithium batteries can potentially explode or catch fire when devices are shipped with a full charge, improperly stored, or improperly packed. Lithium battery related fire incidents have occurred 17 times on passenger flights since 2004, and have been implicated in at least one major crash of a UPS plane.

As a result of the ban, people who want to ship electronic devices to troops or to family overseas will have to use a private delivery service, such as UPS, DHL, and FedEx, which are pricy alternatives.

[. . .]

USPS’s refusal to ship devices with lithium batteries will have the greatest impact on military serving overseas (DHL and UPS do not deliver to APO or FPO boxes) and commercial resellers, who will have to increase shipping costs and rely on FedEx, DHL, and UPS, which still have challenges in countries like Russia.
