Transformer TX project initial funding awarded to AAI Corporation

Filed under: Military, Technology — Tags: , , , , — Nicholas @ 12:14

Remember the “Flying Jeep” proposal? It’s still being pursued, as the initial funding for a flying gyrocopter/SUV has been awarded by DARPA:

Transformer TX, as we have previously reported, is intended to produce a vehicle able to drive on the ground with similar performance to a Humvee or other offroad vehicle. It must also be able to take off vertically with 1,000lb of passengers and payload aboard and fly about at altitudes up to 10,000 feet at speeds equivalent to normal light aircraft.

Perhaps best of all, the Transformer TX is also intended to be fully automated, capable of flying itself with only the most basic guidance from its human operator — who would not, therefore, need to be a highly trained pilot.

Admittedly, I know almost nothing about flying, but this sounds like getting something for nothing (that is, aren’t there laws of physics against this?):

The SR/C idea is basically a winged, propellor-driven light aeroplane with a set of free-spinning autogyro rotors on top. It’s not a helicopter: the engine can’t drive the rotors in flight, and a sustained hover isn’t possible. Nonetheless, though, the CarterCopter can take off vertically as required by Transformer TX rules.

It does this by having weighted rotor tips, meaning that a lot of energy can be stored in the spinning blades (rather as in a flywheel). Sitting on the ground, a small engine-driven “pre-rotator” assembly can gradually spin the rotors up to high speed. The pre-rotator, pleasingly, doesn’t have to transmit a lot of power — thus it is lightweight, cheap and simple compared to a helicopter’s transmission. Nor is the engine required to deliver the massive grunt required to keep chopper blades spinning hard enough to support the aircraft.

Once the rotors are at takeoff speed, the pre-rotator is declutched, the prop engaged and the pitch of the rotors pulled in so that they start to bite air. As they slow down, the energy stored in their whirling weighted tips blasts air down through the disc and the aircraft leaps vertically into the air in a “jump takeoff”.

Sounds amazingly like pulling yourself into the air by your own bootstraps . . .

Still, I’d like to eventually get that flying car I was promised all those years ago.

When the bureaucracy strangles its young

Filed under: Bureaucracy, Military, USA — Tags: , , , — Nicholas @ 07:42

Noah Schactman uncovers the reason it takes a decade for the Pentagon to buy new weapons:

And you thought winning the Afghanistan war was tough. Try building the Army’s new armored vehicle. Or piecing together the Navy’s new network.

All of the complexity of the Afghan conflict — and all of the bureaucracy NATO used to manage the counterinsurgency effort — was summed up by a single spaghetti monster of a PowerPoint slide. “When we understand [it],” war commander Gen. Stanley McChrystal joked when he saw the slide, “we’ll have won the war.”

But that slide was child’s play compared to the three-foot wall chart the military uses to explain its gajillion-step process for developing, buying, and maintaining gear. The “Integrated Acquisitions Technology and Logistics Life Cycle Management” diagram is kind of a precis to the whole interminable progression, from “decompose concept functional definition into component concepts & assessment objective” to “execute support program that meets materiel readiness and operational support performance requirements and sustains system in most cost-effective manner.” Stare long enough, and you’ll start to see why it takes a decade for the Defense Department to buy a tanker plane, or why marines are still reading web pages with Internet Explorer 6.

The chart is put out by the Pentagon’s Defense Acquisitions University, where the Pentagon educates 180,000 people a year on its, um, unique process for purchasing equipment.

Full-sized horror of the slide at the link. If you think you can survive the insanity of it.

The costly San Antonio class

Filed under: Bureaucracy, Military, USA — Tags: , , — Nicholas @ 09:08

Strategypage recounts the sad story of the LPD 17 class:

The U.S. Navy is having major problems with its LPD 17 class amphibious ships. Originally, the plan was for twelve of these ships to replace 41 smaller, older and retiring amphibious ships. Then, disaster struck. Five years ago, the USS San Antonio (the first LPD 17 class ship) entered service. Or at least tried to. The builders had done a very shoddy job, and it took the better part of a year to get the ship in shape. The second of the class, the USS New Orleans, was also riddled with defects that required several hundred million dollars to fix. This pattern of shoddy workmanship, incompetent management and outright lies (from the ship builders) continued with the five LPD 17 class ships now in service. Now the order has been cut to ten ships, partly because of all these problems. To add insult to injury, the last ship in the class is being named after politician John P. Murtha, who is generally hated by soldiers and marines for the way he politically exploited and defamed the troops who served in Iraq and Afghanistan. This is particularly painful because the LPD 17s carry marines into combat.

Many consider the San Antonio class as a poster child for all that’s wrong with American warship construction. The ships are being delivered late, and hundreds of millions of dollars over budget. The list of problems with the ships is long and embarrassing. Although the San Antonio did get into service, it was then brought in for more inspections and sea trials, and failed miserably. It cost $36 million and three months to get everything fixed. The workmanship and quality control was so poor that it’s believed that the San Antonio will always be a flawed ship and will end up being retired early.

USMC learns from LEGO

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

Not the actual toy, but the interlocking and standard size ideas applied to real world training grounds:

Over the last five years, the U.S. Marine Corps has built the world’s largest urban warfare training area at their 29 Palms base out in the Mohave Desert of California. There are currently some 400 structures, from private homes, to large government building complexes, operational in the training area. When development of the center is complete, there will be over 1,200 structures to train in.

[. . .]

Many of the buildings are really shipping containers, equipped with doors, windows, some paint and contents, are being used to represent the buildings. Like Legos, the containers can be joined together, or stacked, to make larger buildings. More importantly, the entire “town” can be rearranged to represent a different kind of environment. The training towns now being built represent what the marines are currently encountering in Afghanistan. But in a few years, the marines may be fighting somewhere else, and they want their training town to reflect that, quickly, when the need arises.

The fully networked infantry comes a step closer

Filed under: Britain, Military, Technology — Tags: , , , — Nicholas @ 08:57

Strategy Page reports on the US Army’s Rifleman Radio project:

The U.S. Army recently conducted a successful field test of their new Rifleman Radio (RR), a 1.1 kg/2.5 pound voice/data radio for individual infantrymen. By itself, the two watt RR has a range of up to five kilometers. But it can also automatically form a mesh network, where all RRs within range of each other can pass on voice or data information. During the field tests, this was done to a range of up to 50 kilometers. The RR can also make use of an aerostat, UAV or aircraft overhead carrying a RR to act as a communications booster (to other RRs or other networks.) The mesh network enables troops to sometimes eliminate carrying a longer range (and heavier) platoon radio for the platoon leader.

The RR has just gone into production, for use as basic communications for individual troops. But in the next 5-10 years, the mesh and data (pictures, maps, at about ten times the speed of dial up Internet) capability will be phased in. During the recent field test, company commanders were able to take a video feed from a UAV, extract a single frame (basically showing where the enemy was), and transmitting this to troops using RRs.

Somewhat surprisingly, the British were pioneering this kind of kit for the troops in Afghanistan in 2002:

Six years ago, the marines bought a thousand Personal Role Radios (PRR) used by British troops since early 2002. These first saw combat use in Afghanistan later that year. The $670 radio set allows infantry to communicate with each other up to 500 meters (or three floors inside a building). The earpiece and microphone are built to fit comfortably into the combat helmet. The radio set itself, about the size and weight of a portable cassette player, hangs off the webbing gear on the chest. Two AA batteries power the radio for 24 hours. The users have 16 channels to choose from and a form of frequency hopping is used to make it very difficult to listen in on transmissions. A small, wireless, “talk” button is affixed to the soldiers weapon so that operation of the radio is hands free. The British have since adopted an improved, and more expensive, version.

Being able to communicate directly with fellow troops in combat is a huge advantage, but the weight and relative delicate nature of earlier radios meant that only platoon leaders and above were routinely provided with radios in the field (usually carried by someone else, not the commander himself).

Welcome back to the draft era

Filed under: Government, Law, Liberty, Military, USA — Tags: , , , — Nicholas @ 07:11

. . . at least, if Representative Charles Rangel gets this piece of dreck through the legislative process:

HR 5741 IH

111th CONGRESS
2d Session
H. R. 5741

To require all persons in the United States between the ages of 18 and 42 to perform national service, either as a member of the uniformed services or in civilian service in furtherance of the national defense and homeland security, to authorize the induction of persons in the uniformed services during wartime to meet end-strength requirements of the uniformed services, and for other purposes.

If this passes, I’ll be happy to welcome the next generation of draft dodgers into Canada. In spite of their sometimes loopy politics, we managed to absorb the last bunch reasonably well.

Even the US Army can’t escape the past

Filed under: Books, History, Military, USA — Tags: , , , , — Nicholas @ 09:28

StrategyPage looks at recent updates to the US Army’s training doctrine, and their need to re-learn from the past:

Over the last few years, the army has been revamping its training and operating manuals to reflect what was learned (or, often, relearned). The army has dozens of manuals, pamphlets and other documents detailing how the troops should be trained, and how they should fight. All these are being brought up to date with what has been learned in Iraq and Afghanistan. Most of what is being lost is speculative stuff added in the 1990s, after the Cold War ended, and the army foresaw a future in which technology would change everything. Tech did bring many changes, but not always as anticipated. Combat and a live (not imaginary) enemy imposes a reality that often cannot be predicted.

For example, five years ago, the army completed a revision of its counterinsurgency (COIN) manual, for the first time in twenty years. The army has a long history of success fighting guerillas. Even Vietnam, which conventional wisdom counts as a defeat, wasn’t. The conventional wisdom, as is often the case, is wrong. By the time the last U.S. combat units pulled out of South Vietnam in 1972, the local guerilla movement, the Viet Cong, was destroyed. North Vietnam came south three years later with a conventional invasion, sending tank and infantry divisions charging across the border and conquering their neighbor the old fashioned way.

[. . .]

The main problem with COIN is that the American armed forces takes it for granted. U.S. troops have been defeating guerilla movements for centuries. Through all that time, COIN has been the most frequent form of warfare American troops have been involved with. But COIN has always been viewed as a minor, secondary, military role. It never got any respect. Even the U.S. Marine Corps, after half a century of COIN operations, were glad to put that behind them in the late 1930s. All that remained of that experience was a classic book, “The Small Wars Manual,” written by some marine officers on the eve of World War II. That book, which is still in print, contained timeless wisdom and techniques on how to deal with COIN operations, and “small wars” in general. Much of the work the army has done in the last five years, to revise their manuals, could have been done just by consulting the Small Wars Manual. In some cases, that’s exactly what was done.

The basic truth is that COIN tactics and techniques have not changed for thousands of years. What has also not changed is the professional soldiers disdain for COIN operations. This sort of thing has never been considered “real soldiering.” But the U.S. Army and Marines have finally come to accept that COIN is a major job, something that U.S. troops have always been good at, and something that you have to pay attention to. So when you see more news stories about the COIN manual, keep in mind the history of that kind of warfare, and how long, and successfully, Americans have been doing it.

“Flying jeep” proposal

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

The Register looks at the “Tyrannos” flying jeep:

Who remembers the “Transformer TX” flying-car project, intended to equip the US Marines with a small four-seat vehicle able to drive about on the ground like a jeep, hover like a helicopter, or fly like a plane? The first team to publicly offer a contending design has now stepped forward.

That design is the “Tyrannos” from Logi Aerospace, allied with other companies and organisations including the South West Research Institute and Californian electric-vehicle firm ZAP.

The Tyrannos is nominally intended to provide Marines with the ability to leapfrog over troublesome roadside bombs, mines, and ambushes while remaining able to drive on the ground as they normally might. However, it promises to be much quieter than ordinary helicopters in use and far easier to fly and maintain.

If the Tyrannos can do all its makers claim, it really does have the potential to become the flying car for everyman.

That last sentence really does wrap up the situation: if it can do all that is claimed, it’ll be a fantastic new toy for the military and (eventually) lead to the flying cars we were promised forty years ago. The specs seem hopelessly optimistic, but perhaps I’m just jaded because I don’t have a flying car of my own yet . . .

Reader beware, however. The Transformer TX project is being run not by the Marines themselves but by DARPA, the Pentagon crazytech agency which won’t even touch a project unless it is extremely unlikely to succeed.

“Give us ideas that probably won’t work,” that is DARPA’s motto: and the Tyrannos team assembled their design specifically to DARPA requirements. And, let it be noted, they have yet to satisfy even DARPA’s very relaxed rules on what kind of ideas should get taxpayers’ money spent on them.

Sometimes simple ideas are best

Filed under: Middle East, Military, USA — Tags: , , , — Nicholas @ 09:02

A case where super-sizing is a good thing:

The product was inspired by a marine who, while serving in Somalia in 1993, thought it an obvious thing to have large size wipes. But there was no such product on the market. So the ex-marine took the idea to a friend who ran a gym, who then developed the product and found someone to manufacture it. All that took fifteen years, from the time the sweaty marine in Somalia got the idea.

Klenz Showers is a towel sized (2×4 feet/61x122cm) baby wipe. It was designed so that the package containing it fit into the pockets of field uniforms. The Klenz Showers wipe was large enough to clean yourself up, and feel refreshed. There was no scent, but there was aloe, so that the wipe helped heal the usual scrapes troops accumulated out in the bush. To keep the Klenz Showers light, you have to add four ounces (120ml) of water before using.

In the last two years, the Klenz Showers have become a major boost to morale, and cleanliness, for troops in Afghanistan, where many of them are out in the hills for weeks at a time. After ammo, water, batteries and food, the troops want their Klenz Showers packets.

Once you get past the initial “Dude, it’s a baby wipe” reaction, this is actually a really good idea.

Retired US general apologizes for smear on Dutch troops

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

Former USMC general John Sheehan has apologized for his remarks about gay Dutch soldiers in the Srebrenica massacre:

An ex-U.S. general has apologised after saying Dutch UN troops failed to prevent the Srebrenica genocide partly because their ranks included openly gay soldiers, the Dutch defence ministry said Tuesday.

John Sheehan, a retired former NATO commander and senior Marine officer, “wrote a letter of apology,” ministry spokeswoman Anne van Pinxteren told AFP.

In it, Mr. Sheehan said he was “sorry” for remarks made at a Senate hearing earlier this month where he argued against plans by President Barack Obama to end a ban on allowing gays to serve openly in the US military.

[. . .]

Mr. Sheehan claimed that Dutch leaders, including the former chief of staff of the Dutch army General Henk van den Breemen, had told him that the presence of gay soldiers had contributed to the fall of the enclave which led to the massacre of nearly 8,000 Muslim men and boys.

There were a lot of reasons for the massacre, but the sexual orientation of individual soldiers in the Dutch contingent had nothing to do with it.

Is this the beginning of the end for “Don’t ask, don’t tell”?

Filed under: Military, USA — Tags: , , , , , , , — Nicholas @ 10:14

US Defense Secretary Robert Gates has announced some changes to the “don’t ask, don’t tell” policy that makes it a bit less easy to force gay or lesbian service members out of the armed forces:

The Pentagon announced immediate changes on Thursday to make it more difficult for the military to kick out gay service members, an interim step while Congress debates repeal of the existing “don’t ask, don’t tell” policy.

Defense Secretary Robert Gates told a news conference that the directives included raising the rank of those allowed to begin investigation procedures against suspected violators of the “don’t ask, don’t tell” policy.

If you wonder why even a small step like this has been so long in coming, this explains how deeply embedded anti-homosexual attitudes can be:

Well now we know. The reason Western forces failed to prevent the massacre in Srebrenica in 1995 is because of the gays. You see the Dutch lifted a ban on homosexuals in the armed services in 1974 and ever since then the Nancy boys have been so busy watching Sex and the City, baking flans and checking out the backsides of their hetero comrades-in-arms that the whole operation has gone to pot.

This is the theory floated with an ironically straight face by retired Marine General John Sheehan during congressional hearings on abandoning Don’t Ask Don’t Tell, Bill Clinton’s cowardly split-the-difference policy on gays in the service. The General’s criticism wasn’t limited to the Dutch, mind you; he thinks many European armies have gone “soft” owing to liberal social engineering projects.

General Sheehan may be more representative of attitudes at the higher levels of the armed forces than Secretary Gates. I don’t get it, but this is nothing new. As I wrote back in 2008:

As a recruiting policy, DADT is just plain dumb. As a “retention” policy, DADT is worse: gay and lesbian soldiers are pretty clearly determined to serve — in spite of the widespread anti-gay mentality pervasive in some units — and are being dismissed from the service for being honest. This, at a time when all branches of the US armed forces are struggling to maintain troop levels. It’s a stupid, dishonest policy and should be discarded ASAP.

Oh, and here:

It’s truly mind-boggling that the US military can still justify this stupid policy: being gay isn’t a crime, and is becoming “normal” across the country, yet it still counts as a reason to drum someone out of the military. This, at a time when the armed forces are finding their demands for personnel outstripping the supply.

A gay man or a lesbian woman is no more a threat to the efficient functioning of a military unit than anyone else — all things being equal — and may well be more motivated to succeed because they’ve volunteered to serve in spite of the idiotic “Don’t ask, don’t tell” policy.

Harrier replacement’s first hover test

Filed under: Britain, Military, Technology, USA — Tags: , , , , — Nicholas @ 09:49

The F-35B from Lockheed Martin is intended to replace the Hawker Harrier for the US Marine Corps and the Royal Navy. Here’s a short video of the test plane in its first test of hovering and then a slow-speed landing:

H/T to Lewis Page, who writes:

Though the F-35 had been planned to be bought in thousands by the US forces alone, suggesting good economies of scale and affordable prices for export customers down the road, critics of the programme are now alleging that costs are so far out of control that the well-known military procurement “death spiral” process has set in: higher price, less planes bought, unit cost driven up even higher, even less planes bought and so on.

However it’s important to note that if the F-35 is successful it has the potential to destroy large amounts of the present global military aerospace industry. If it does get made in large enough numbers to be offered cheaply in time, it will be more sophisticated and yet cheaper than any other combat jet on the market, in all likelihood putting several of its competitors out of business in decades to come. This is probably a major reason why so many aerospace people are desperate for it to fail.

But there are others who feel that the Western fighter jet industry is overlarge, bloated, has no real threat to confront any more and is consuming funds which might be better spent on simpler things such as infantrymen or helicopters. They might be hoping that the F-35 can resolve its problems.

Earlier posts on the F-35, particularly from the Royal Navy’s viewpoint here.
