F-22 flies again

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 07:21

The months-long grounding is over:

On September 21st, the U.S. Air Force will allow its F-22 fighters to fly again. The aircraft had been grounded for 140 days because of problems with the pilot’s oxygen system. The air force is not giving out many details on exactly what the problems is, although they say a report on the F-22 oxygen system will be out by the end of the year. Each F-22 will undergo a detailed inspection before it is cleared to fly. This may have something to do with earlier remarks about toxins somehow getting into the pilot’s air supply. The problem was always about something bad in the air supply. This has kept all 168 F-22s grounded since May. The only exception was a squadron based on the Virginia coast, that was given permission to fly out of the way of hurricane Karina. Those F-22s encountered no problems with their air supply.

[. . .]

During the grounding, pilots and ground crews used simulators and (for the ground crews) maintenance exercises on the grounded aircraft to keep their skills sharp. In addition, everyone helped checking out a growing list of aircraft components in support of the search for the breathing problem). The air force was also under time pressure to fix the problem. That’s because after 210 days on the ground, aircrew have to undergo extensive retraining to regain combat flying status. This added a little more urgency to fixing the problem quickly. The grounding also left a dozen F-22s stranded at a training base, where they were for live weapons exercises. At least six new F-22s could not be delivered because of the grounding.

How spendy will those whizzy F-35 aircraft end up being?

Filed under: Military, Technology — Tags: , , , — Nicholas @ 09:31

Strategy Page has a state-of-play report on the escalating cost of the F-35:

The U.S. Department of Defense and the U.S. Air Force are trying to agree on what the new F-35 fighter will cost. The air force insists that it is $65 million each, while the Department of Defense says when all costs are included; it will be more like $111 million each. Another number being debated is how many F-35s will actually be produced. The air force assumes 3,162, but the Department of Defense is not so sure that many will eventually be built. Total development cost is now put at $65 billion, which comes to over $20 million per aircraft if 3,162 are built. Development costs for the new U.S. F-35 fighter-bomber has grown by more than a third over the last few years. The additional development costs are accompanied by additional delays. Current estimates are that the F-35 will enter service in another 6-7 years. The Department of Defense believes production and development costs will continue to rise, and that the number to be built will decline. Both trends increase the average aircraft cost. Based on past experience, the higher Department of Defense estimates are more likely to be accurate.

And then there are operating costs. Earlier this year, after months of contentious disagreement, the U.S. Air Force came around to agreeing with U.S. Navy claims that the F-35 will cost much more to maintain, rather than (as the F-35 promoters assert) less. It was over a year ago that the U.S. Navy, after nervously watching as the manufacturing costs of the new F-35C and F-35B carrier aircraft increase, concluded that these aircraft would also be a lot more expensive to maintain. It comes down to this. Currently, it costs the navy, on average, $19,000 an hour to operate its AV-8 vertical takeoff or F-18C fighter aircraft. The navy calculated that it would cost 63 percent more to operate the F-35C (which will replace the F-18C) and the F-35B (which will replace the AV-8). These costs include buying the aircraft, training and maintaining the pilots, the aircraft and purchasing expendable items (fuel, spare parts, munitions.) The navy concluded that maintenance alone would be about a third more.

In a vicious circle, the higher the cost per plane, the fewer planes will be built, which increases the cost of the planes that do get built. At some point, the costs will get so high that foreign buyers (who are expected to buy more than half of the planned production) will reduce their orders or even back out altogether. The F-35 was supposed to be cheaper to operate than the aircraft it will be replacing, but that appears to be a badly mistaken estimate. That will also tend to ratchet down the foreign interest in purchasing the aircraft.

Is the end of the manned fighter plane at hand?

Filed under: Military, Technology — Tags: , , , , — Nicholas @ 09:08

Yes, I know we’ve gone through this discussion before (and the comment thread on that first entry is still a good summary of the counter-arguments). Air-to-air combat has become only a small part of what the air forces of the world are expected to do: ground support, while generally disdained by air force brass hats, is the most common combat task now. Here’s the state of play, according to Strategy Page, as far as the future of air combat is concerned:

The last decade has revolutionized air warfare, and air forces. This revolution was brought about by two technologies (smart bombs and UAVs) that have been around for decades but, over a decade ago, became reliable and capable enough to have a decisive effect on warfare. Now UAVs armed with smart bombs are poised to replace manned aircraft. Moreover, the proliferation of GPS guided weapons and short range guided missiles have greatly reduced the need for ground strikes by manned or unmanned aircraft. Since World War II, air forces have demanded, and obtained, a disproportionate share of military budgets. No more.

[. . .]

Underlying all of this is the appearance of so many cheaper, reliable, precision weapons in the last decade. This has changed tactics on the ground. While the air force doesn’t like to dwell on this, it’s the war on the ground that is decisive, not what’s going on in the air. This proliferation of precision has also changed the way smart bombs were designed. With the ability to put a weapon within a meter of the aiming point (using laser guidance) or 5-10 meters (using GPS), smaller is now better, at least in urban areas where there are a lot of civilians about, troops have changed the way they fight. There is more movement in urban warfare because of all this precision firepower, and fewer friendly fire casualties from bombs and artillery. But it’s not just the air force and their smart bombs that have brought this on. The army had precision missiles on the ground long before JDAM came along. Now the army has more of them. Thus, over the last five years, there has been a competition between the army and air force to develop smaller, cheaper and more precise, missiles and bombs.

[. . .]

The air force is not happy about the army having a large force of armed UAVs. Many air force generals believe the army should not have the MQ-1C, or at least not use them with weapons. That has already caused some spats in the Pentagon over the issue, but so far the army has prevailed.

The army argument is that these larger UAVs work better for them if they are under the direct control of combat brigades. The air force sees that as inefficient, and would prefer to have one large pool of larger UAVs, that could be deployed as needed. This difference of opinion reflects basic differences in how the army and air force deploy and use their combat forces. The army has found that a critical factor in battlefield success is teamwork among members of a unit, and subordinate units in a brigade. While the air force accepts this as a critical performance issue for their aircraft squadrons, they deem it irrelevant for army use of UAVs. Seeing army MQ-1Cs doing visual and electronic reconnaissance and firing missiles at ground targets, the air force sees itself losing control of missions it has dominated since its founding in 1948.

[. . .]

Meanwhile, the navy has taken the lead in developing larger, jet propelled UAVs like the 15 ton, X-47B. This UAV uses a F100-PW-220 engine, which is currently used in the F-16 and F-15. The X-47B can carry two tons of bombs or missiles and maneuver like a jet fighter. The X-47B is fast and agile enough to carry out air-to-air missions. With the right software, it can do this autonomously (without human intervention). This is being worked on, and the navy already has perfected the software that enables a UAV to land on aircraft carriers.

The coming decade will see more and more UAVs replacing manned aircraft. Thus after only a century in action, manned combat aircraft are on their way out.

Far north transportation solution: heavy-lift dirigibles?

Filed under: Britain, Cancon, Technology — Tags: , — Nicholas @ 09:11

It’s like the airborne equivalent of the monorail: the wonderful solution to various air transportation problems. Unfortunately, they usually fail to live up to expectations. A joint British-Canadian effort to introduce heavy-lift airships for transportation in Canada’s far north hit the news today:

Last week, Yellowknife-based Discovery Air signed a preliminary agreement with British aviation startup Hybrid Air Vehicles to buy a fleet of futuristic dirigibles to haul cargo and supplies across the Canadian North

Costing $40-million each, the massive vehicles will be able to haul 50 tonnes of cargo, stay in the air for several weeks at a time and use a fraction of the fuel consumed by standard fixed-wing airliners.

By comparison, the largest aircraft in the current Discovery fleet can only carry 7,000 pounds and stay aloft for a matter of hours before refuelling.

The new vehicles, which are still in the early testing phase, may look like little more than sleek reboots of Depression-era dirigibles, but actually are a unique marriage of four different aviation technologies, say designers.

“It actually works more like an airplane than an airship,” said Gordon Taylor, marketing officer for Hybrid Air Vehicles.

The aircraft fly using a combination of aerodynamic lift and helium buoyancy, manoeuver by using a helicopter-style thrusters and they land on a curtain of air like a hovercraft.

It’ll be great if they can work as designed, and also survive the extreme weather conditions of Canada’s far north, but the smart money isn’t likely to bet that way.

Subsidized flights from remote locations

Filed under: Government, Politics, USA — Tags: , , , — Nicholas @ 12:57

Steve Chapman knows where to get the “best” deal in government subsidy of domestic flights:

As a resident of Illinois, I’d never had any particular desire to fly from McCook, Nebraska, to Denver. But lately, I’ve been looking for an opportunity. Turns out the federal government is willing to pay me a handsome fee to do it.

Oh, I wouldn’t get the cash directly. But the Department of Transportation provides more than $2 million to subsidize that particular route, which works out to about $1,000 for every passenger. My fare, meanwhile, would be less than $150.

I could get an even bigger hand on the hop from Lewistown, Montana, to Billings—$1,343. But if I’m feeling the need for indulgence, there is nothing to beat the flight from Ely, Nevada, to Denver, for which Washington will kick in $3,720. For that sum, of course, it could buy me a perfectly functional used car.

These extravagances are part of the Essential Air Service initiative, which is part of the reason for the recent congressional impasse over a bill to keep the Federal Aviation Administration operating.

F-22 fleet still grounded due to pilot oxygen supply problems

Filed under: Military, Technology, USA — Tags: , , , , — Nicholas @ 12:08

Earlier this month, I linked to an article about the F-22 oxygen problems. According to Strategy Page, the problem still has not been resolved:

The U.S. Air Force is making some progress in finding out what is wrong with their F-22s. It appears that some toxins are somehow getting into the pilot’s air supply. This has kept all 168 F-22s grounded for three months, so far. Despite the new findings, the air force still has not nailed down the exact cause of the problem, much less fixed it. The U.S. Navy had a similar problem with its F-18s (there were 64 incidents between 2002-9, resulting in two dead pilots). The navy found that the problem was carbon monoxide getting sucked into the aircraft air system (which the navy modified, eliminating the problem). The air force is looking into the navy experience with these similar problems, to see if there is anything similar going on with the F-22s.

First F-35C catapult launch

Lewis Page has more:

The test launch took place on the landbased steam catapult at US Naval Air Station Lakehurst (also the location of a prototype electromagnetic one of the type the Royal Navy will be compelled to use).

The F-35C is intended to operate from the catapult-equipped fleet carriers of the US Navy and will equip the Royal Navy and the RAF too. The jumpjet F-35B (formerly the chosen British model) will now be delivered only to the US Marines to begin with. The F-35A version, intended for ordinary landbased runway operations, will serve with the US Air Force and many allied nations.

Farewell Space Shuttle . . . you massive boondoggle

Filed under: Bureaucracy, Space, Technology — Tags: , , , — Nicholas @ 12:25

I’ve been ambivalent about the space shuttle program for decades — not because I’m anti-space, but because I think the shuttle was government methadone to replace a real space program. At that, I hadn’t connected all the dots the way Scott Locklin has here:

The Space Shuttle, an object lesson in the Sunk Cost Fallacy, has been with us since my early youth. This preposterous boondoggle was originally supposed to make manned space flight cheaper: to the point where getting a pound of matter into space would be as cheap as sending it to Australia. That was the only purpose for building the damn thing in the first place. The idea was, if your spaceship was reusable, it would be cheaper to send people and heavy things into space. If using the same thing multiple times isn’t cheaper, well, what’s the point? Conspicuous consumption, perhaps?

In one of its original incarnations, the Shuttle was supposed to launch like an ordinary aircraft. A jet + rocket powered “first stage” heavy lifter would propel the craft into the upper atmosphere, and the rocket propelled second stage would send the thing into space. Seems like a good idea to me. Jets are pretty easy to fly and maintain cheaply. Jets also don’t have to carry vast quantities of oxidizer. Plus; you get to reuse the whole mess.

Unfortunately, the politicians decided that building the first stage heavy lifter would cost “too much.” Instead they changed the design, and strapped a couple of solid rockets to a beefed up “orbiter” and giant non-reusable fuel tank. That wasn’t the worst of it: those pieces should have still in principle provided for a cheap launch vehicle. In practice, the silica tiles and engines turned out to have very high maintenance costs involving substantial labor, and turn around times were 1/6 of what they should have been, making the thing 6 (though more like 10) times as expensive as it was designed to be.

The goal of the space shuttle program was to have safe, re-usable spacecraft that could lift heavy loads to low earth orbit at a cost of about $50 per pound. What they ended up with was a dangerous fleet of hangar queens that took loads to orbit at an estimated cost of $50,000 per pound. That’s quite a missed set of goals.

The continuing problems of the F-35 Joint Strike Fighter

Filed under: Military, Technology, USA — Tags: , , — Nicholas @ 07:57

The Economist titles this piece “The last manned fighter”:

The latest cost estimates from the Government Accountability Office (GAO), published in May to coincide with a Senate Armed Services Committee hearing on the F-35 programme, were shocking. The average price of each plane in “then-year” dollars had risen from $69m in 2001 to $133m today. Adding in $56.4 billion of development costs, the price rises from $81m to $156m. The GAO report concluded that since 2007 development costs had risen by 26% and the timetable had slipped by five years. Mr Gates’s 2010 restructuring helped. But still, “after more than nine years in development and four in production, the JSF programme has not fully demonstrated that the aircraft design is stable, manufacturing processes are mature and the system is reliable”. Apart from the STOVL version’s problems, the biggest issue was integrating and testing the software that runs the aircraft’s electronics and sensors. At the hearing, Senator John McCain described it as “a train wreck” and accused Lockheed Martin of doing “an abysmal job”.

What horrified the senators most was not the cost of buying F-35s but the cost of operating and supporting them: $1 trillion over the plane’s lifetime. Mr McCain described that estimate as “jaw-dropping”. The Pentagon guesses that it will cost a third more to run the F-35 than the aircraft it is replacing. Ashton Carter, the defence-acquisition chief, calls this “unacceptable and unaffordable”, and vows to trim it. A sceptical Mr McCain says he wants the Pentagon to examine alternatives to the F-35, should Mr Carter not succeed.

How worried should Lockheed Martin be? The F-35 is the biggest biscuit in its barrel, by far. And it is not only Mr McCain who is seeking to knock a few chocolate chips out of it. The bipartisan fiscal responsibility and reform commission appointed by Mr Obama last year said that not all military aircraft need to be stealthy. It suggested cancelling the STOVL version of the F-35 and cutting the rest of its order by half, while buying cheaper F-16s and F-18s to keep numbers up. If America decided it could live with such a “high-low” mix, foreign customers might follow suit.

F-22 still grounded

Filed under: Military, Technology, USA — Tags: , — Nicholas @ 09:53

What initially seemed like an urgent, but relatively trivial problem with the F-22 may involve more time out of service:

What appeared as a simple problem with the U.S. F-22 fighter, has kept 168 of them grounded for over two months, so far. It all began when it appeared that the F-22 fighter might be having a problem with its OBOG (OnBoard Oxygen Generating) system, causing pilots to get drowsy, or even black out, from lack of oxygen. There have been five reports of potential problems in this area lately. As a result, on May 3rd, all F-22s were grounded. But the U.S. Air Force is also checking the OBOGs in F-16, F-15E, A-10, F-35 and T-6 aircraft as well. The problem may just be with the F-22 OBOG, or a general problem with all air force OBOGs. The air force also believes the F-22 problem may not just involve the OBOG. As a result, the grounding is “indefinite” and will continue until the source of the breathing problem is found, and definitely fixed.

If it goes on too long, the air force may consider fitting some F-22s with the older air supplies, just so some of their newest combat aircraft will be available for combat. In the meantime, pilots and ground crews are using simulators and (for the ground crews) and maintenance exercises on the grounded aircraft (in addition to checking a growing list of aircraft components in support of the search for the breathing problem) to retain their skills. The 168 F-22s, costing over $200 million each, have become the most expensive hanger queens (aircraft that spend a lot of time sitting in a hanger getting repaired or worked on) ever.

Horwitz: Yes, it is a police state

Filed under: Government, Liberty, USA — Tags: , , , , — Nicholas @ 08:18

It’s been a long time since 9/11, and the biggest losses have been in civil liberties:

As regular readers know, I’m not one for hyperbole, so perhaps some are thinking that my title is ironic. Nope, I mean it. An accumulation of events in recent months leads me to no other conclusion than that we are in fact living in a police state in the good old US of A.

The list of reasons is fairly long, but we can certainly start with our favorite gropers at the TSA. In my ideal world, airline safety would be the responsibility of those with the most directly to lose financially from doing it poorly: the airlines and the airports. But even in a world where government has taken on that responsibility, we should be protected by the Fourth Amendment against “unreasonable” searches. It’s one thing to walk through the standard metal detector, which seems reasonable, but when we are expected to pose virtually nude in a submissive position for government agents, and when refusing to do so earns you a feel-up that would count as sexual battery in most states, that is something else entirely.

If I had told you 20 years ago that in 2011 this is what would happen every day to thousands of travelers — including toddlers and the handicapped — at U.S. airports, you would not have believed me. And on top of everything else, it doesn’t work! It’s mere “security theatre.” When residents of the United States have a legitimate fear of being sexually abused by agents of the State when engaging in peaceful air travel, we live in a police state.

Rare WW2 German bomber discovered off British coast

Filed under: Britain, Europe, Germany, History, Military, WW2 — Tags: , — Nicholas @ 11:32

What may be the only intact example of the German Dornier 17 bomber has been discovered in the Goodwin Sands off the coast of Kent:

The plane came to rest upside-down in 50 feet of water and has become partially visible from time to time as the sands retreated before being buried again.


Image from Reuters

Now a high-tech sonar survey undertaken by the Port of London Authority (PLA) has revealed the aircraft to be in a startling state of preservation.

[. . .]

Known as “the flying pencil,” the Dornier 17 was designed as a passenger plane in 1934 and was later converted for military use as a fast bomber, difficult to hit and theoretically able to outpace enemy fighter aircraft.

In all, some 1,700 were produced but they struggled in the war with a limited range and bomb load capability and many were scrapped afterwards.

Striking high-resolution images appear to show that the Goodwin Sands plane suffered only minor damage, to its forward cockpit and observation windows, on impact.

“The bomb bay doors were open, suggesting the crew jettisoned their cargo,” said PLA spokesman Martin Garside.

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.
