Hopefully not. Extensively is difficult - which i discovered after some back of the envelope calculations on AIP reactant consumption. That makes a lot of sense to me. Still, I think even if patrolling in those locations is the plan, ... the training and skill to operate under the ice for as...

That is interesting. I agree unlikely to have transiting the NW passage totally submerged. Even with AIP/Lithium batteries, there are major limitations with a conventional submarine in the Arctic. A submarine can only go for so far with using the AIP, before the submarine runs out of embarked...

yes ... RN crew. Typo on my part.

I agree. Although perhaps I go a step further, and I speculate that the AIP/lithium battery of the Type-212CD will be a significant advance over the AIP/lead-acid propulsion of the NRP Arpão. This in turn could mean significantly more operation possible under the ice than the NRP Arpão's...

I agree. I hope the RCN can find the personnel to start this planning - and if/as required identify any long lead activities and potential procurement. This, I believe, is a massive challenge given the current shortages the RCN is trying to overcome. The mobile base 'solution' is a bigger...

NavyShooter / Stoker ... that was interesting. So I dug into this a bit and learned (albeit I could have this wrong) ... The Route Survey System Life Extension (RSSLE) for the Royal Canadian Navy's Kingston-class Maritime Coastal Defence Vessels (MCDVS) integrated the ISE Aurora active...

I recall reading that during HMCS Chicoutimi's delivery transit from Scotland to Canada in October 2004, seawater entered the submarine through an open hatch in heavy seas, causing electrical arcing and short-circuits that ignited cable insulation and panels. The resulting fires were...

Another aspect (which frankly I fear is less likely to happen) is the dynamic to improve the fidelity of charts of the North West passage so to help the RCN. I believe the Canadian Hydrographic Service (CHS), an organization housed within Fisheries and Oceans Canada (DFO) is the official...

Reading the translations from Portugese of the Youtube video's text of the NRP Arpão (TKMS Type-214 variant AIP-lead-acid battery propulsion submarine) under ice approximate 4 day (only) journey, had me pondering some (but clearly not all) relevance to the RCN. I suspect that successfully...

I think we all hope the same. I confess to having a fear that the shift the RCN will face, going from only 1 operational active sea going submarine (out of quantity 4) to having instead having up to 4 to 5 operational active seagoing more capable AIP/Lithium battery propulsion submarines (out...

I don't think those translations are the best, and some details and nuances may have been lost. Here are the approximate words (I may have missed a few words or have a few words wrong) from the Canadian naval officer (submariner) who was onboard NRP Arpão (where I think this was only 4 days...

Given Canada is planning to procure 15 River Class Destroyers, I thought I would compare such against current NATO naval forces using the criterion of currently commissioned NATO warships in active service, counting frigates and destroyers only (excluding cruisers, corvettes, patrol vessels...

Next I thought it useful to compare this Portuguese Navy's NRP Arpão (TKMS Type 214 variant) to Canada’s preferred supplier TKMS with the Type-212CD – where I tried to confine myself to aspects relevant to Arctic operations. From what I have read, the Portuguese Navy's NRP Arpão (TKMS Type 214...

In the end, I decided to copy selected translations from the Portugese language video about the Portuguese Navy's "NRP Arpão (TKMS Type-214 variant AIP-lead-acid battery) submarine under ice journey. I note from what I read, also onboard was: Danish naval officer Canadian naval officer...

I'm all for that viewpoint. They IMHO are incredibly useful in a number of areas. In terms of surveillance they can useful with IR/Visual sensors, with R-ESM and possibly C-ESM interchangeable payloads. I also like that larger UAS could potentially both drop sonobuoys and relay sonobuoy...
