Canada’s Cormorant fleet to stay airborne thanks to former “Marine One” helicopters

Filed under: Britain, Cancon, Italy, USA — Tags: , , , , — Nicholas @ 12:29

The Cormorant is not quite the success story we hoped for when we bought the helicopters for our search and rescue operations. Part of the problem is that spare parts for the choppers are in very short supply. An unexpected source of spare parts just happened to come our way recently:

The helicopters sold to Canada are the so-called US101 version of the EH101 aircraft developed during the 1980s and 1990s in the UK and Italy by companies which are now grouped as AgustaWestland. The UK forces, after massive delays and cost overruns, eventually received two versions, both known as “Merlin” — a naval submarine-hunting variant and a cargo or troop-carrying one for the RAF. Both types finally reached frontline useability around 2004-2005, but their availability rates have been poor: perhaps due to the fact that the Merlin didn’t sell well worldwide and thus parts were at a premium.

However the Merlin did sell to the Bush administration, which was seeking to replace its ageing VH-3 Sea King presidential helicopters operated by the US Marines (the president’s chopper becomes “Marine One” when he is aboard, just as his airforce-operated plane becomes “Air Force One”). But the US101 project, managed by Lockheed on behalf of AgustaWestland, soon became mired in cost and time overruns every bit as bad as those which had hit the Royal Navy’s HM1.

The plan might well have been doomed from the outset, with requirements calling for 14 VIP seats, hardening against electromagnetic pulse, an executive washroom and communications equivalent to “a flying Oval Office” — a pretty big ask for an aircraft which can only lift four tonnes in its RAF cargo-carrying incarnation.

The US101 problems became bad enough that each new Marine One copter was projected to cost as much as an Air Force One jumbo jet, and the costs became an issue in the presidential election — with both Mr Obama and his opponent John McCain vying to issue the strongest condemnation of the aircraft. Obama in particular described it as “procurement amok”, and unsurprisingly it was axed as soon as he took office.

Now the Canadians, who also operate the EH101 under the name “Cormorant”, have snapped up the former presidential fleet of nine aircraft for $164m.

Helicopter footage of 9/11 just released

Filed under: History, USA — Tags: , , , , — Nicholas @ 12:21

The Guardian explains:

Previously unseen footage of the 9/11 attacks, filmed from a police helicopter hovering above the burning World Trade Centre, has emerged almost a decade after the terrorist atrocity.

The New York Police Department air and sea rescue helicopter was dispatched to the scene of the attack to see whether any survivors could be rescued from the rooftops.

[. . .]

The video is part of a cache of information about the attack handed over by city agencies to the National Institute of Standards and Technology, the federal agency that investigated the collapse.

It was released by NIST on 3 March under a Freedom of Information Act request, but it remains unclear who published the footage online.

UK government trying to further economize on helicopters for Afghan service

Filed under: Asia, Britain, Military — Tags: , , — Nicholas @ 08:25

Lewis Page is concerned that, on top of the wrong-headed approach to cutting military costs, the coalition government may further reduce the Chinook helicopter plans:

In its last months in office, the previous Labour government announced plans to order 22 new Chinook helicopters (in addition to two which would replace recent combat losses in Afghanistan). The money was to be found by cutting squadrons of fast jets — in particular, Tornado low-level deep strike bombers. The first 10 helicopters were to come into service in 2012-13.

On arrival in office the Coalition carried out a Strategic Defence Review, personally supervised by Prime Minister Cameron, in which it was decided that the Tornado bomber fleet would be preserved intact, the Chinook order would be cut to just 12 — and, controversially, that the Harrier jumpjet fleet would be scrapped entirely.

Even the much reduced Chinook order has so far failed to actually be signed, and there have since been suggestions that the Ministry of Defence financial assumptions which underlay the Review were too optimistic – thus, that more cuts might be required.

It’s “like asking an alcoholic to run a distillery”

Filed under: Cancon, Economics, Military, Politics — Tags: , , , — Nicholas @ 13:26

The dissent on the announced purchase of F-35 fighter jets continues to gain traction:

In an interview on CBC’s Power and Politics last night, Industry Minister Tony Clement admitted we are buying the F-35s because the military wants them. “It is the best plane on the market. I will say on your program, I’m not the expert. The military are the experts. Why don’t the Liberals take the word of the Canadian military on that?” he asked.

Let me count the ways. A brief read of the A-G’s report on the purchase of military helicopters suggests a host of reasons why allowing the Department of National Defence to dictate procurement is like asking an alcoholic to run a distillery.

Sheila Fraser’s report concluded that National Defence knew, but did not tell the politicians, that the helicopter it wanted was not an “off-the-shelf “ model, with a relatively low risk of cost and time overruns.

In the event, the total cost for the 15 Chinook heavy lift helicopters more than doubled to $4.9-billion from the $2-billion price tag when the project was presented to the Conservative government and approved. Helicopters that were initially scheduled to be delivered last July, now won’t be ready until June 2013 — a state of affairs Ms. Fraser decried as “totally inappropriate”.

I’m not convinced that the F-35 is the aircraft Canada actually needs, and the DND’s track record on equipment purchases combined with the ultra-spendy pricetag on the F-35 make me concerned that they’re going to put themselves in the same state as the British armed forces by over-committing to kit that they (that is, we) can’t afford.

Pakistan’s self-harming border closure

Filed under: Asia, Economics, Military, Railways — Tags: , , , — Nicholas @ 11:22

Strategypage shows why Pakistan is doing itself more harm than good on the Afghan border:

After a recent incident where U.S. helicopter gunships crossed into Pakistan, in hot pursuit of Islamic terrorists, and killed three Pakistani soldiers (and a lot more terrorists), Pakistan cut one of the two NATO supply routes that pass through Pakistan. Aside from the fact that the Pakistani soldiers fired on the NATO helicopters (which they often do, even when the choppers are on the Afghan side of the border), the U.S. didn’t have to remind the Pakistanis that such a gesture was self-defeating. The Pakistani government is heavily dependent on American economic and military aid, and more and more of the supplies for foreign troops in Pakistan is coming from non-Pakistani sources. This hurts Pakistani businesses that move, and often provide, the supplies.

At the moment, about half those supplies come through Pakistan. The Pakistanis only closed, for about a day, one of the two main routes. About 30 percent of the supplies come in via Central Asia railroads, and another comes from the Black Sea, via rail to the Afghan border. The remaining 20 percent comes in by air. But some of that may be shifted to the Central Asian route, which is much safer (from bandits, bad roads and the Taliban) than the Pakistan routes.

Pakistan may have helped create conditions that will actually improve the economies of several other countries:

Shipping supplies to Afghanistan via Russian and Central Asian railroads has advantages for the nations it passes through. Russia has an economic interest in this, as more traffic makes it financially attractive for Central Asian nations to invest in upgrading their rail connections to Afghanistan. Tajikistan, for example, is extending its railroad to the Afghan border by building another 145 kilometers of track. Afghanistan itself has no railroads, mainly because there is not enough economic activity in the country to make this worthwhile. Foreign donors have contributed billions of dollars since 2002 to build more paved roads in Afghanistan. Currently, there are 42,000 kilometers of roads there, but only a third are paved. There are few rivers, much less navigable ones, and no access to the sea. The place has long been a logistical nightmare. Most Afghans recognize that roads will make the country more prosperous, by making it economically feasible to export many commodities, and cheaper to bring in, and distribute, foreign goods. Naturally, the Taliban are opposed to all this road building, as it threatens the poverty and ancient customs that Islamic conservatives are so fond of.

Free flight in Indian helicopter? No, thanks, I’ll walk.

Filed under: India, Military, Politics — Tags: , , , — Nicholas @ 07:51

Strategy Page would recommend that you think twice before climbing aboard an Indian helicopter:

The Indian Air Force is being criticized for mismanaging its fleet of over 300 helicopters. It gets worse when you realize that this is not enough helicopters for all of the needs of the Indian armed forces. But despite that, over ten percent of those helicopters are diverted to UN peacekeeping operations and for transporting VIPs (senior government officials). In addition, it’s been publicized that helicopters are often assigned to fly the wives of senior air force officials. That, and maintenance problems, mean that only about 60 percent of the helicopter fleet is available for military needs.

It gets worse. Despite needing a third more helicopters, the helicopters are dying of old age. As in 78 percent of current choppers have exceeded their design life. The aging equipment was no secret, but the navy only began obtaining new helicopters in the last three years (and for the five years before that obtained none.)

Cooling the (Navy’s) jets

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

The carrier variant of the F-35 fighter and the V-22 tilt-rotor helicopter both present an unexpected problem to carrier crews: the risk of melting the deck. The heat of the exhaust on both of these aircraft can cause damage to the carrier’s deck if they are left running for more than a short period of time. Strategy Page reports:

The navy sought a solution that would not require extensive modification of current carrier decks. This includes a lot of decks, both the eleven large carriers, and the ten smaller LHAs and LHDs. This began looking like another multi-billion dollar “oops” moment, as the melting deck problem was never brought up during the long development of either aircraft. Previously, the Harrier was the only aircraft to put serious amounts of heat on the carrier deck, but not enough to do damage. But when you compare the Harrier engine with those on the V-22 and F-35B, you can easily see that there is a lot more heat coming out of the two more recent aircraft. Someone should have done the math before it became a real problem.

The solution to the V-22 heat issue is pretty straightforward: put heat-resistant pads under the exhausts, but the F-35 requires a (hopefully minor) redesign of the exhaust nozzles to diffuse the heat.

Litany of problems with new NH-90 helicopters

Filed under: Australia, Europe, Germany, Military, Technology — Tags: , — Nicholas @ 09:25

Strategy Page reports that new NH-90 helicopters delivered to Australia are showing similar problems to the laundry list of issues the Germans reported when their NH-90s went into service:

The German Army conducted an evaluation of their new NH-90 helicopters, and were not pleased. Their conclusion was that, for combat missions, another model helicopter should be used whenever possible. A particular problem was the lack of ground clearance. The NH-90 can’t land on a piece of ground with any obstacles higher than 16 cm (6.4 inches). That makes many battlefield landing zones problematic. That assumes you can even get on a NH-90 and find a seat. The passenger seats cannot hold more than 110 kg (242 pounds). Combat equipment for German troops weighs 25 kg (55 pounds), meaning any soldier weighing more than 85 kg (187) has to take stuff off, put it on the floor, than quickly put it back on before exiting. Then there’s the floor, it’s not very sturdy, and combat troops using the helicopter for a short while, cause damage that takes the helicopter out of action for repairs. Worse, there is the rear ramp. It cannot support troops carrying all their equipment, making it useless for rapid exits of combat troops. There is not enough room in the passenger compartment for door gunners. There are no strap downs for larger weapons, like portable rocket launchers or anti-aircraft missiles. The passenger compartment also does not allow for carrying cargo and passengers at the same time. The winch is not sturdy enough for commandoes to perform fast roping operations. And so on. The Germans were not pleased with the NH-90.

I’ve never specced out a new helicopter design, but these complaints sound like issues that should have come up during the initial design review, not things that appear once you’ve taken delivery. It sounds like the military equivalent of buying a new car without taking a test drive or checking the specifications for how well the vehicle matched your actual requirements.

Design fail, manufacturing fail, or ordering fail?
