The engines are not an issue as you say, don't turn them off. It's the hydraulics and the reservoir. Wrapping it in insulated tarps was somewhat successful. There was talk of running smaller engine cooling lines through the reservoir with valves to turn them on or off depending on the temps...

My experiences with extended periods of -30 or more is anything running hydraulics needs to have a means of heating the oil as it became very sluggish and near frozen fluids put a lot of strain on seals and hoses. But if those concerns have been addressed in South Korean equipment then they...

With the more than passing interest by members here in South Korean tanks, tracked artillery, and the Redback IFV is there information available on whether this equipment has been exposed to and tested in -20 to -40 temperatures? Since the South Koreans seem eager to sell would it not be...

What? No fromage? Zut alors!

Manitoba recently completed Bipole lll, a 500kv direct current line from generating plants in the north to Winnipeg. Direct Current lines are more efficient and have much less line losses but do require converter stations at either end to go from AC to DC and then the reverse from DC to AC. The...

New technolo New technologies such as geomembranes require very little digging. They're almost laid on the surface and rock and gravel dumped on top. The roads basically "float" on muskeg and permafrost.

With Canada cozying up to Europe the A400m may be a likely replacement for the J models.

Paved is a bad idea north of the 55th. It would fall apart from freeze/thaw and require more than annual maintenance. For a 4 season 4 lane highway gravel is easily maintained and much cheaper to build although still an expensive proposition. A lot of the dollars would be eaten up with hundreds...

It's, as you say, an infographic and not a final design. Once the customer presents its requirements, as with any other type or class then the design firms up to meet those requirements. Same process preceded the AOPS, River Class, and JSS. If the CF and the government get serious about...

I originally leaned towards an LST/LSM for the same reasons. However it may be very difficult to build a forward landing ramp and and have an ice breaking hull. The G-LAM needs some tweaks in my opinion (like much larger landing craft and maybe a well deck plus an increase in lane meters for...

The icebreaker LPD concept would not only be useful in the ice but anywhere else it is sent. Even if the Russians and Chinese are detected what can The CF do to deter their landing? Fly a few CF188 over their heads? Right now that's it. I agree wholeheartedly that an urgent need is to upgrade...

An ice strengthened LST or JSS (Davies GLAM for example) is not a warfighter but will deliver warfighting capabilities. The fact that they would be "ice breakers" would give them the ability to move and not be the sitting duck. They would not be a quick response but they could deliver a whole...

So if the Russians or Chinese decide to "claim" Borden Island or Mackenzie King island or Prince Patrick Island etc (and don't say they wouldn't, it is what they've done in many other locales) and set up a token base to solidify that claim what can troops in Iqaluit or even Alert do? Unless...

Pre-outfitted Seacans, Add a few Husky 8's from Foremost and you can set up shop fairly quickly.

They're of little use to the stated priority of defending the Arctic then. If the money's there then get something to project power into the arctic. Something to get the Army to where they're needed and land them with support from helis. If done right these same vessels can be used anywhere else...

Talk of the Griffon replacement combined with recent suggestions to create a national firefighting force could the Griffons be rerolled into that new organization? Just a thought.

The Cavour, Mistral, etc, are fine ships but they would not be something to sail north into arctic waters very often, if ever. Canada would need ships with similar capabilities that are ice capable to at least the same as the AOPS. A modified Wallenius Sol or more likely built for purpose...

If connected to mainland Canada ports are more likely to have deep water and docks however the many islands and hamlets rarely if ever have those facilities. Therefore some sort of LST or Smaller LHD with larger landing craft provide the capability to "land" larger vehicles. Finding a beach is...

A RORO needs a dock which means deep water, a very very rare thing in the Arctic.
