The Department of National Defence plans to develop a new stealth snowmobile for covert military operations in Canada's Arctic, with $550,000 set aside to build a prototype.

Ottawa has posted a public tender for a hybrid-electric snowmobile that would allow Canadian Forces soldiers to swoop silently across the frozen landscape.

The vehicle would perhaps be the most unconventional tool in the arsenal of a Conservative government promising to beef up Canada's military might in the North.

The nature of these future clandestine assignments is unclear from the federal tendering document. But one thing is clear: silence is priority No. 1.

Existing engines apparently aren't up to the job.

"The noise level of an internal combustion engine cannot be reduced to an acceptable level for missions where covertness may be required, especially given the increased propagation of sound in cold, dry, Arctic air," reads the tender, posted last week by National Defence's research and development agency ....

We already send funding to the universities, so why not cut costs and get McGill to prototype one with military specs?

Knowing full well that as soon as they got the contract, they'd start insisting on additional funds/time to figure out how to plug the 1500km extension cord into the Churchill power grid.

This idea is brilliant, now all they have to do is make sure it has enough power and torque to drag along the 'tactical quiet' generator behind it.

Must be April Fools Day or at least August Fools Day.

It seems to me that if the CF are fighting a technological equivalent enemy in the Arctic, that all a hybrid electrical snowmobile would do is provide more easy targets for the enemy.

I think reducing the noise of the engine would do little to protect the snowmobile born forces. An enemy force with minimum technology should be able to target the snowmobile using IR, mast mounted LLTV cameras, simple motion detectors, and if the enemy is able to get 10 to 15 meters up, they should be able to see the snowmobile trails left by the tracks of the snowmobile.

While a powered source of snow transportation could be a real game changer, if you're looking for concealable vehicles, perhaps a 5 or 6 man iceboat might be a better idea.  There would be problems relying on the wind to transport troops to a time schedule. You can't count on the weather to do what you want it to. Even larger iceboats, with proper materials and heat insulation could transport a section and it's support weapons and supplies.

The Canadian Press - ONLINE EDITION
Operation Silent Snowmobile: Canadian Forces plan new vehicle for covert Arctic ops
By: Andy Blatchford, The Canadian Press

The Department of National Defence plans to develop a new stealth snowmobile for covert military operations in Canada's Arctic, with $550,000 set aside to build a prototype. Ottawa has posted a public tender for a hybrid-electric snowmobile that would allow Canadian Forces soldiers to swoop silently across the frozen landscape.

The vehicle would perhaps be the most unconventional tool in the arsenal of a Conservative government promising to beef up Canada's military might in the North. The nature of these future clandestine assignments is unclear from the federal tendering document. But one thing is clear: silence is priority No. 1.

Existing engines apparently aren't up to the job.
"The noise level of an internal combustion engine cannot be reduced to an acceptable level for missions where covertness may be required, especially given the increased propagation of sound in cold, dry, Arctic air," reads the tender, posted last week by National Defence's research and development agency. "Electric snowmobiles are a potential solution to this problem, eliminating the internal combustion engine and using a much quieter electric motor to drive the track system."
Since coming to power, the Conservatives have gradually increased the Canadian Forces' presence in the resource-rich Arctic. Prime Minister Stephen Harper has made annual trips to the region, where he's appeared in carefully orchestrated photo-ops on ice floes as jets screamed overhead.
A government spokeswoman could not immediately provide information as to why the military would need snowmobiles for clandestine operations. But one northern security expert said this could be a signal the government is getting serious about Arctic sovereignty.
Whitney Lackenbauer considers the project a departure from the government's usual in-your-face military approach to the Arctic. "To me, it very clearly suggests that someone within the Canadian Forces perceives the need to actually have substantive capabilities, rather than simply acting symbolically in the region," said Lackenbauer, a historian at the University of Waterloo. "Up to this point, as I see it, the focus has very much been on showing the flag. So it's not about keeping your activities quiet, it's about broadcasting it to the world as loudly as you can."
Still, he has no clue what kind of scenarios National Defence has foreseen for it to want — or need — stealth snowmobiles. "I'd be interested in knowing what the military envisions as being the threats that it's going to encounter with these," he said, speculating they might be useful to stop smugglers or other criminal activities. "I'm at a loss to know what that is."
The tender calls for the snowmobile to have a range of at least 15 kilometres when it operates in its quiet, electric mode at an average speed of 20 km/h on level snow.
The vehicle must also be able to hit a top speed of at least 75 km/h. In its gas-power mode, the snowmobile must be able to maintain a speed of 30 km/h while towing a payload of 250 kilograms on a sled, and it must have a range of 100 kilometres.
"It also must have the ability to switch to 'silent' mode easily and quickly with minimal tools, at which point it can function solely on electrical power," the tender says.
The document says bids cannot exceed $550,000 and a prototype must be completed by March 31, 2013.
Hybrid snowmobiles are not yet available from major manufacturers, but a McGill University engineering professor said the idea is on the cusp of commercial breakthrough.
Peter Radziszewski has helped students build experimental electric and hybrid snowmobiles at the school over the last decade. He doesn't see any reason why constructing a hybrid snowmobile to the tender's specifications wouldn't be feasible — as long as the producer can work with the government's tight budget.
Radziszewski said the hefty challenge of maintaining performance in a machine weighed down by two engines and a stack of batteries won't be easy, either.
"It becomes a heavy, heavy snowmobile," he said. "It's very difficult."
Radziszewski highlighted that the electric motor offers environmental benefits of zero emissions — a feature not even raised in the government tender.
"I really don't know what their interests are, but one can well imagine... that silence is golden in this particular case," Radziszewski added. Rob Huebert, a University of Calgary political scientist, called the project good military planning for a region that could see increased activity by smugglers, illegal aliens and organized crime in the future.
"We're starting to see individuals that you would probably want to be able to sneak up on," said Huebert, associate director of the school's Centre for Military and Strategic Studies.
"I think what you're going to find is the more you look, the more you find."

Article Link

This article for some reason puts the emphasis of using the hybrid snowmobile in the Arctic, the actually MERX as posted earlier just says a hybrid snowmobile and doesn't make any mention of the Arctic.

Edit: I just read the "Statement of Work" that Milnews.ca had posted in another forum. That Statement of Work does mentions an emphasis for the operations in the Arctic. My bad.

Cold effects depend on battery types used... there's all sorts of battery options, and plenty of non-traditional storage alternatives...

I'm guessing (Hoping???) when the article says they're investing in a snowmobile, they're actually investing in something more substantial then slapping a few batteries in a yammy (Which I just don't see happening), instead looking at developing a hybrid diesel-electric or gas-electric vehicle along the lines of a BV206.

Running on batteries to electrical motor rather then generator to motor would substantially reduce the thermal profile of a vehicle (Let it cool after shutting off the generator, and it could run at almost ambient temperature), and reduce the noise signature to more or less zero.

Of course, the further you want to go "silently" the more batteries you need... batteries typically fall into two categories... heavy or expensive... pack in more batteries to go further, you loose more troop or cargo carrying room... expand troop or cargo carrying room, add more batteries... downward spiral of space and weight...

Which of course, leaves you with a rather large vehicle... and extremely visible in the open arctic...

Back to slapping a few batteries in a yammy, I just don't see their being enough room in the vehicle to make any sense...

Non-battery battery-style substitute.

"I can't believe it's not battery".

(Capacitors act as an electrical storage device, and have been used in roles similar to batteries. Many newer MP3 players for example use capacitors rather then batteries. Not familiar with carbon nano tube capacitors, but a quick bit of google shows they may be an option in hybrid electric car designs)

Jim, think of whittling off the wood and drilling out most of the middle of a pencil...then shrink that hollow tube of graphite by 1,000,000 times.  Now line a bunch of those little tubes up with each other to make a layered, porous structure with a temperature-tolerant electrical gel of sorts, and you can store lots of electrical power in that structure.  A lot more efficient than the big, aluminum canister, paper-wrapped capacitors of old.  Such "supercapacitors" have a higher energy density than even the most advanced Lithium-ion batteries in use today.

Part of the reason hybrid drive works for cars is that energy is recovered through the use of regenerative braking: the breaks act as generators and take mechanical energy out of the wheels by converting it into electricity for later use in moving the car (as opposed to friction and heat in the case of conventional brakes).  I've never driven a snowmobile but I assume that, when you want to stop, you just lay off the throttle?  Is there actually any brake?

It makes a hybrid drive more efficient, but will work just fine with out it.
There are brakes on a snow mobile, but it's not going to be used enough to improve the efficiency of the vehicle through regenerative braking.

Regenerative braking is a fairly simple process, usually it's accompanied by another form of braking (in hybrid cars, generally mechanical braking). The mechanical brake being intended primarily for "stopping" and the regenerative brake intended primarily for "slowing down".

Great for recovery of energy that would be otherwise wasted in say, driving down a long step hill, and braking to keep speed from increasing.

Probably not going to add much efficiency in the arctic tundra on snowmobile with no posted speed limits though.

If/when carbon nanotube capacitors become a viable technology, it would probably make more sense to use them to power trucks, LAV's, small ships or even light UAV's. Of course, a unit the size of a radio battery would probably keep a soldiers radio, GPS, NVG and iPhone powered up for a week or so, so there are lots of high impact uses for supercapacitors....

It’s not as if Canada has any alpine enemies to sneak up on with shadowy, frigid cavalry. But that’s not going to stop the Canadian Department of National Defence from spending a half million dollars on a prototype."

Only downside is that they will now have to let a contract for someone to develop a white solar panel, then it would be truly stealthy.

Not sure how this happened, but this reply ended up being posted in the "What is Canada Buying? thread:

Playing the devil's advocate for a second here:

US SOF teams inserted into the Sha-i-kot valley up to a week prior to OP ANACONDA, usually infiltrating via 4X4 ATV's. The high mountain passes were coverd in snow, and on least one occasion, the team discovered curious Taliban fighters following the tracks the ATV's left (although they never actually seemed to have followed through with the tracking). The SOF ATV's were not described in great detail (this information is from the book "Not a good day to die), but the inference is they were modified for SOF use. It seems probable that part of the modification would be to install larger or more efficient sound supressing mufflers along with racks to carry more gear, and possibly mor powerful engines. Certainly there is no indication in the book that the Taliban were aware of the SOF entry into the Sha-i-kot valey, so the sound of the ATV engine was muffled to the point no one was able to hear it.

Now hybrid electric is flavour of the month, and anyone who has been around a Toyota Prius moving away from a stop sign can attest to the total lack of sound as the electric motor starts the car in motion, so having a silent snowmobile seems to be one way to combine the lessons of over smow mobility and stealth in a package that is more familier to most Canadians.

</advocate>
OTOH, mobility and logistics are pretty closely related, and if I were in charge of things, I would be investigating TDI diesel engines for the entire vehicle fleet since the enhanced reliability and fuel economy would have a much greater impact on CF operations. (A VW Jetta with a TDI engine can claim 40+ MPG without the extra weight or complexity of electric engines, battery packs and control electronics. Larger and heavier trucks and AFV's would not get 40 mpg, but even a 5-10% improvement would have a dramatic impact on costs, or even the number of trucks needed to carry fuel).

Moving quietly with a TDI engine would simply involve putting sound insulation around the engine compartment and installing a high efficiency muffler, both probably simpler and cheaper than a hybrid showmobile.

That could work.  Hybrid vehicle, gas for distance, and when using gas have solar panels exposed.  When you want to go stealth you hit the battery, cover the panels, move in quietly.

GAP, quick, let's go out and patent "Temporally-Variable Stealth Technology"!!!   ;D

ohhhh....you're quick........such a techie, marketable name for darkness......it'd probably work too!!

Moving quietly with a TDI engine would simply involve putting sound insulation around the engine compartment and installing a high efficiency muffler, both probably simpler and cheaper than a hybrid showmobile.
Exactly.  It wouldn't have to be TDI, although that might suit the military better, but an even less complicated and less expensive solution would be simply to modify existing snowmobile engines which are getting pretty good these days.

This hybrid idea is ridiculous to the extreme.

To be fair they can be used below the circle, Canada does tend to be covered by snow at least once a year.

Seriously where does this stuff come from? I'm guessing half a million on stealth snowmobiles (we had em up north...they were called snowshoes and sleds) fits perfectly into this cost cutting stuff.

I'm starting to think a snowmobile is a waste of time altogether. Petawawa and other bases are being overrun with ATV's and vehicles like Gators are/were used in Afghanistan. ATV's can be used year round, and having one light vehicle fleet rather than two or multiple types simplifies logistics greatly.

The Argo ATV is probably the best vehicle to fit this category; it has ultra low ground pressure, is amphibious, uses skid steering so you can throw a set of tracks over the wheels for extreme conditions and (for Technoviking) is large enough to carry a C-16 and a decent amount of ammunition. There is no reason you can't include a trailer as well for the other stuff (besides a C-16  ;)) that you might want to take. Use a small diesel engine with an efficient muffler and a soundproof engine enclosure and you are 100% there.
Dagny, this is not a battle over material goods. It's a moral crisis, the greatest the world has ever faced and the last. Our age is the climax of centuries of evil. We must put an end to it, once and for all, or perish - we, the men of the mind. It was our own guilt. We produced the wealth of the world - but we let our enemies write its moral code.

I'll have to disagree here.
An Argo will never do things a snowmobile can do. Although Argo's are decent vehicles they sure lack in speed. If used in a role where stealth is a factor & things go to crap, speed could be your only option to safety.
As for a diesel motor these tend to suffer in extreme cold conditions when they are allowed to become cold before starting up.
Same would apply to an electric snowmobile. For any amount of range, speed & carrying capacity would have to be greatly sacrificed. Refueling would also pose problems with electrics. A gas engine can haul extra fuel or could be resupplied by caches or airdrops. Not a good option for electrics.
Atv's also fall far short of snowmobiles on performance on snow & ice.
If the use is for Arctic conditions with combat operations in mind a snowmobile fits the needs best. As already stated to reduce noise extra insulation & better mufflers on existing engines would be the best & most cost efficient option.

Another thing to consider would be weather conditions.
During a windy situation in the Arctic other sounds would be severely masked.
During extremely still weather the sound of a completely quite vehicle(engine noise) would be nullified by the noise created by it's ski's, tracks or wheels moving over an extremely cold surface.

Stipulated, but I am thinking of the bigger logistics picture:

1. All other vehicles and almost all generators now use diesel engines and JP-8 fuel.

2. We are currently supporting dozens of "mini fleets" of specialized vehicles, which entails huge logistics and maintainance bills. Why add to the puzzle with more mini fleets? (On a meta level we really need to get our s**t together with trucks, LAVs, AFV's etc. before even looking at the ultra light fleet)

3. While an ARGO isn't very fast, snowmobiles are not very amphibious. Throw in tracks fitted over the wheels for extreme conditions (deep sand, snow, swamps etc.) and with the ARGO you have one vehicle that can operate in virtually every sort of terrain we are likely to encounter. The only vehicle that comes even close is the BV-206 and various related vehicles (Viking and ST Kinetics Bronco), which are much larger and more complex.

If we are going to spend a boatload of money for improbable vehicles like a Toyota Prius on tracks, then we might as well design an ARGO like ATV which addresses your concerns; higher top speed, Diesel engine with preheater and why not make it an 8X8 to carry a section's worth of kit and ammunition or 2 stretcher patients.

Although I agree that logistics are very important but when the intended mission is "military operations in Canada's Arctic" function of the equipment has to take overall precedence. It is not an environment where compromise is a viable option.
The Agro for combat operations in the Arctic would be a disaster. On top of lack of speed, amphibious operations with an Argo would also be not advisable & also not very likely needed. If you think their slow on land you never been in one when it's swimming. They do not handle rough water & entry and exit places have to be well chosen. Staying dry in them under anything but ideal conditions while swimming would be next to impossible.

To me the big question is why the thrust for "covert military operations in Canada's Arctic" when so little has been done to expand our conventional operational capabilities in the Canadian Arctic?
The logistical tail is quite long there and for any prolonged response other than on a small scale much infrastructure is needed.
Manned patrol bases (manned on a rotational basis) capable of handling greatly increased staffing quickly would be a far better method of protecting our sovereign territory than this covert operations scheme.
Rations, fuel and other required equipment and supplies could be pre-positioned to somewhat limit the logistical needs required for increased activities.
But I'm sure that's just a pipe dream as that would cost more money & staffing than the covert operations scheme. :facepalm:

It is a DRDC research project.  As opposed to actually developing any future CAF vehicle, this project will probably do more to inform a future capital project to replace the LOSV fleet.

Diesel Electric systems have been applied to:

Ships
Trains
Buses
Trucks
Cars

and now Snowmobiles.

The advantages of Diesel(Gas) electric systems are:

Longer operating lives
Reduced fuel costs
Quieter operations (equates to fuel efficiency)
Exportable power.

It appears that the advantages demonstrated in large systems have now been tested in a small system.  The small system could end up powering not just snowmobiles but ATCs, UAVs and even small boats.   That would put the benefits of hybrids into systems that can be transported ship to shore by helicopter.

It would give the military some new options ..... and as a by-product possibly make cottage country a quieter place.

Given the usual March Madness spending shenanigans $625,000 doesn't seem to me to be an egregious waste of taxpayers money.  I can find you some much more expensive R&D projects with considerably less growth potential.

DND unveils "Loki Stealth Snowmobile" for CF's "covert Arctic ops"

007, North of 60: Canadian Forces test stealth snowmobile for covert Arctic ops
By Andy Blatchford, The Canadian Press

The Canadian military has been secretly test-driving a $620,000 stealth snowmobile in its quest to quietly whisk troops on clandestine operations in the Arctic.

The Canadian Press has learned that soldiers have taken the new hybrid-electric snowmobile prototype on trial runs to evaluate features such as speed, noise level, battery endurance and acceleration.


The Department of National Defence even has a nickname for its cutting-edge, covert tool: "Loki," after the "mythological Norse shape-shifting god."

Word of the federal hunt for a stealth snowmobile first surfaced two years ago when National Defence's research and development agency posted a public tender.

That 2011 tendering document, however, offered few details on the future of these missions, except for the top priority: silence.

The project kicked off at a time when the Conservative government was laying out promises to boost Canada's military muscle in the Far North, in a once-vaunted package of Canadian Forces upgrades the feds have largely failed to implement.

Prime Minister Stephen Harper arrived in the Arctic on Sunday for a six-day tour of the region, where his government's main focus has gradually moved from improving the country's northern military capabilities to promoting economic development.

The stealth-snowmobiles project has withstood that political shift.

National Defence has made it clear it does not intend to spend any more money on Arctic mobility for eight years, but its research branch says the evaluation of the silent snowmobile, though still in its early stages, will continue.


The Canadian Press obtained a report that offers a behind-the-scenes peek at how soldiers ran the prototype through "informal" tests in February across varying snow conditions on Canadian Forces Base Petawawa.

"These experiments compared Loki against commercially available snowmobiles already in use, testing a wide variety of the snowmobiles' characteristics, including speed, towing capacity, endurance, mobility, usability, and of course, noise emissions," says the heavily redacted report, acquired under the Access to Information Act.

In one test, military personnel used sound-meter readings to compare the prototype's noise performance against two gas-powered snowmobiles.

Another trial saw the machine driven at a steady speed on a mix of flat terrain and hilly snow-covered roads until batteries died.

Soldiers wielding a radar gun also tested the stealth snowmobile's acceleration as it raced 100 metres down a flat, snow-packed track.

"The prototype must be at least nearly as capable and reliable as a standard internal combustion snowmobile, while providing a significant noise reduction," the report said.

"For military purposes, it is not enough for a snowmobile to operate quietly."

The report also found potential gaps in the military's assessments.

"One of the difficulties encountered in evaluating Loki is the lack of a standard set of CF snowmobile requirements," the document said.

The quest, meanwhile, to develop a silent snowmobile remains highly secretive.

Large sections of the May report, such as test results and comments, were blacked out.

The document justified its omissions under different provisions of the Access to Information Act, including one that says information is withheld because releasing it could be injurious to the defence of Canada or the detection, prevention or suppression of subversive or hostile activities.

A government spokesman declined to make the report's author available for comment, nor did he answer questions on why Canada's military wants the unconventional snow machine.

"In general, anything in the military that's quieter is going to be advantageous," Noel Paine, a spokesman for Defence Research and Development Canada, said.

"Whether it flies or goes on the sea or anywhere else, if it's quieter it's advantageous to any military."

Later, in an email, Paine said the testing and evaluations are ongoing.

He also said the Canadian Forces are looking at different small vehicles that "can be modified to traverse all types of difficult terrain, under various conditions. This includes, but is not limited to, vehicles such as snowmobiles."

In the original federal tender, Ottawa said it was seeking a snow machine that would run by gas-powered engine, but would have the capability to easily switch to a "silent mode" electric motor.

"The noise level of an internal combustion engine cannot be reduced to an acceptable level for missions where covertness may be required, especially given the increased propagation of sound in cold, dry, Arctic air," read the tendering document, which also indicated bids could not exceed $550,000.

It also said National Defence's research agency was "pursuing the development of a 'silent' snowmobile for winter operations in Canada, specifically in the Arctic."

The Canadian Press obtained the contract, which listed the revised price tag at nearly $620,000.

The winning bid came from CrossChasm Technologies, which is based in Waterloo, Ont., and also has an office in Montreal.

Simon Ouellette, the firm's director of project development, refused to discuss the stealth snowmobile due to a confidentiality agreement with National Defence.

One Arctic policy expert questioned whether the cost of developing such a vehicle is money well-spent, particularly since he doesn't believe there are any significant security threats in the Far North.

"I don't see a whole lot of evidence that criminals and terrorists are scooting around Canada's North on snowmobiles and that we have to sneak up on them," said Michael Byers, a former federal NDP candidate who teaches international law at the University of British Columbia.

Byers said he's not sure whether defence officials have an accurate picture of Canada's actual needs. Perhaps, he added, they have an obsession with high technology.

"I can't help but wonder whether they've been watching too many (James) Bond movies."

If you're interested in a bit of backstory, there's an earlier thread (now merged with this one) associated with the 2011 tender call, with the original 2011 MERX listing (with a link to the bid package) here.

Edited to add the following:
And this, from the company:
Quote
Insider’s info on electric snowmobiles

We woke up this morning and learned that we had been living the geeky engineer’s “dream life” for 15 months from fall 2011 to winter 2012 without even noticing it. According to the media rumor, we spent almost a year and a half working on some crazy stealth snowmobile vehicle straight out of James Bond’s legendary high tech lab operated by Q!

According to press reports, this all started in 2011, when CrossChasm Technologies, was awarded a research and development contract from Defence R&D Canada Suffield in order to research the noise emissions of off road vehicles. As part of this contract, a hybrid snowmobile capable of driving in electric mode had to be developed.

Scenario from a James Bond movie?  Not quite…

R&D project looking to advance the understanding of noise in off-road utility vehicles and foster technological development related to hybrid drive systems in extreme environments? Yes.

The reports make this R&D project sound like it’s straight out of a science fiction movie. Maybe it’s because we’ve been doing hybrid and electric vehicle R&D projects for automotive OEMs and tier 1 suppliers, the Canadian Space Agency and various other vehicle manufacturers for years that we failed to see the “James Bond” factor on this one.  When you work on electric and hybrid vehicles all the time, the lack of details on electric snowmobile in the published articles doesn’t really make your imagination run wild anymore.

SPOILER ALERT!!! If you want your imagination to keep running wild with regards to electric snowmobiles stop reading now! We’re about to show you pictures of what and electric snowmobile looks like.

So what does an electric snowmobile look like?!? Boringly enough, they look like a standard snowmobile. (Not that different from how an electric car looks like any other car)

Don’t believe us?

Here are pictures of the most northerly located electric snowmobile on the planet. Hard to tell it’s electric! You’ll have to believe us on this one. :)




This vehicle, designed and assembled by CrossChasm on an existing utility snowmobile platform is currently in operation at a remote U.S. National Science Foundation research base in Greenland named Summit Station (www.summitcamp.org).

Thanks to the fact that it produces no emissions when driving, this electric snowmobile (nicknamed Edison by base staff) is capable of transporting scientists and equipment into a “clean air zone” atop the Jakobshavn glacier at an altitude of 10,000ft, one of the world’s most unique scientific research sites.

So where does that leave us now? Unfortunately, Miss. Moneypenny, still doesn’t work at our front desk and we have to get back to our calculators and our labs to do more electric and hybrid vehicle work. It’s not James Bond worthy but we enjoy our daily routine of custom designing advanced vehicle systems, developing mobile apps related to electric vehicles (Android, iPhone)  and helping utilities deploy charging networks around the globe.

That being said, if you hear that Q is looking for development partners, please let us know.

They do now.  Have you worked recently with modern Tier-2 common-rail diesels in the cold? They are not like the diesels of past.  Electrics, when primarily solid-state regulated are quite reliable in a wide range of temperatures.

When one also considers the logistics of fuel, particularly in the North, it's pretty hard not to give diesel consideration.  Add to that, the ability of a future LOSV to also output pure electricity for user consumption, and that's not at all an unreasonable power configuration.

The concept seems to be a bit of dog.  Although the Patrol did get to dog it on the return trip to base (1100 km).  It was found to hard to teach them new tricks.

I have spent a lot of my life battling to keep diesels running in the cold.  I do not have a ton of experience with anything new other than the new pick up trucks.  If there's a diesel that's as reliable in the cold and easy to start as a gasoline engine, that's (good) news to me.

When I said electrics don't like the cold, I was mostly referring to batteries.

I've had a new common-rail diesel tick over in a half second crank with no glow-plugs at -43ºC....pretty impressive!

No No, mount lasers on the dogs heads. They'd be like a Fricken Land Shark ;D

Interesting article from a McGill team that designed and built a hybrid snow mobile.

Development of a 1
st Generation Series Hybrid Snowmobile

McGill University
Copyright © 2007 SAE International
ABSTRACT
The McGill University Electric Snowmobile Team, returns
to the Society of Automotive Engineers Clean
Snowmobile Challenge (SAE CSC) in 2007 with a
revised electric snowmobile prototype and an all new
hybrid prototype. This paper covers the design and
development of the hybrid snowmobile prototype.
This completely new design uses the team's experience
in the electric snowmobile domain to assemble a
snowmobile which can have all the advantages of
electric drive systems while at the same time not being
too limited by the battery's energy density. The goals for
this initial design were to make a simple and reliable
prototype which can serve as a baseline for further
refinement of the hybrid concept in the future.
This design paper covers the challenges of hybrid
snowmobile design as well as the possible advantages
of such a vehicle. The design decisions made by the
team in the conception of this 1
st generation prototype
are reviewed and, when available, preliminary results are
given .

It is my understanding that the military is moving away from gasoline powered vehicles and moving towards a common fuel (JP-8?).

Oh Well Then......that should solve all kinds of problems with attaining fuel in a remote village.....or just about anywhere snowmobiles can be ridden.....everyone has JP8, but gasoline....not so much..... :sarcasm:

Interesting point.

Does that suggest that our DOMOPS fleet requires a different fuel profile than our Expeditionary fleet?  Overseas the most commonly available fuel will be whatever the US provides - and I understand that to be JP-8 or possibly some algal green biodiesel hybrid stuff.

Meanwhile, back here at home, gasoline and diesel are readily available.  And the commercial engines are cheaper than the military ones - as well as having a broad range of suppliers of "In Service Support".

JP-8 is used in CF aircraft and the US is moving to a all JP-8 fuel for their vehicles.  Interestingly JP-8 is chemically very similar to kerosene.  Not being an engine guy wouldn't anything that can burn kerosene as a fuel can burn JP-8, that includes diesel engines.  What does change is wear and corrosion on certain engine parts, and that might require a flex fuel type engine.  Nothing you can't buy readily civi side for many things.

A few years ago the power plants diesel generators at CFS Alert were converted to JP8.  One fuel for all applications make life much more easier.

Often the change is in the fuel pumps and injectors. The lubrication factor of the fuel for internal parts comes into play as does the ignition point of the fuel which can also require changing the timing of the engine. Gasoline motors really don't do well on kerosene, Jet A or JP-8. Never tried Jet-B but if you have a buddy and his car to lend me I would get him to try it.

I mixed some gas with kerosene to put on a Renault Estafette http://www.google.ca/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&docid=Vtrnw9IY2VS7VM&tbnid=pwYzwxxUVbrcKM:&ved=0CAUQjRw&url=http%3A%2F%2Fcommons.wikimedia.org%2Fwiki%2FFile%3ARenault_Estafette_001.jpg&ei=EFQWUvnaDuqP2gXy_YHACw&bvm=bv.51156542,d.aWM&psig=AFQjCNEuS-zH43-B-vi6pZaA5rpDyr3Arg&ust=1377281390582341  in order to get me to the beach (in Panama) and it ran quite smoothly - a bit smoky though...
Now I am SAS or SWAT dude ;-)

The 'pana" is a play on the Greek 'pan' meaning 'all' or 'encompassing' - not quite but similar to UBIQUE
some think I just misspelled "para" :-)

GAP, JP-8 is wide-cut kero and pretty darn close to Arctic Grade A diesel, which is the most plentiful fuel up North.  ;)

ME Gas is a lot rarer, by volume/quantity stored.
