You forgot Sweden's A-26,which are being build(1st of 2) as we speak(Oceanic Version) :nod:

And true,first projects that will be started are the 12 MCM ships(replacement Tripartite class,decision probably next month or so,on which design is chosen),Belgium leads in this project,after that (probably in the

next few months also)a decision will be made on which design is chosen to replace the ASW/GP frigates.(Netherlands leads)and will be a class of 4(to start with,possibly an option for 2 more for the

Netherlands),shortly after that(thinking around May),the winning design for the new sub will be chosen,so busy times for the Dutch Navy.

Also an extra CSS(Combat Support Ship) will be build,and joining the Navy around 2021/22(decision has been made about that one)

Basically modernising 3/4 of our Navy.

Thanks I didn't realize the A26 was that far along, delivery scheduled for 2022, just in time to start building new subs for Canada!

Unfortunately we 'upgrade' everything, even if that means it costs more in the long run.  We've done it with fighters, MPAs, and are doing it with the Victoria class. 

It is the Canadian way (based off the past "how we've done things" since...when CANEUR closed, or probably even before that!).
Everything happens for a reason.

Sometimes the reason is you're stupid and make bad decisions.

DND extends life of submarine escape suits beyond expiry date as fleet shows its age

Liberals plan to modernize and sail the navy's 4 aging submarines until 2040

The Canadian navy's stock of survival suits, which allow submariners to escape in an emergency from a sunken boat, has been thrown a lifeline after much of the equipment had reached its expiry date, federal documents reveal.

The critical safety suits give stranded crew members the ability to ascend from a depth of 183 metres and protect against hypothermia.

They even inflate into a single-seat life raft once on the surface.

The orange whole-body suits were part of the original equipment aboard the Victoria-class submarines, diesel-electric boats originally built for the Royal Navy and purchased from Britain in the late 1990s.

Documents obtained by CBC News show there was concern among naval engineers, in late 2016, that many of the suits had passed or were about to pass their best-before, safety dates.

A spokeswoman for the Defence Department said a decision was made to extend the life of suits while the federal government procures new ones — a process that is ongoing.

There is no threat to safety, said Jessica Lamirande.

"The service life extension was approved based on successful, rigorous testing at the Naval Engineering Test Establishment on a representative sample of suits that had passed their intended service lives," said Lamirande, in a recent email.

"Testing consisted of detailed visual inspection, leakage tests, and functional testing."

Fleet sailing until 2040

But defence experts say it is a small project that speaks volumes about the Liberal government's plan to modernize and keep operating the four submarines until 2040, a proposal that was articulated in the latest defence policy.

Retired commander Peter Haydon, who also taught defence policy at Dalhousie University in Halifax for years, said keeping submarine replacement parts and equipment in the system has been an ongoing headache for the navy, dating back to the 1980s.

However, the bigger concern is: As the boats age, the strength of their pressure hulls declines.

The  government plans to modernize the boats, but Haydon said that's fine for the electronic and other components.

"You can modernize most things, but you can't modernize the hull, unless you build a new hull," he said.

Pressure to buy new

The Senate and House of Commons defence committees have recommended the government begin exploring options now for the replacement of the submarines, which took years to formally bring into service after they were purchased.

The government, in its response to a committee report last fall, argued it is already fully engaged building Arctic patrol ships and replacements for frigates and supply ships.

Buying new submarines is a topic that has been debated behind the scenes for a long time at National Defence with one former top commander, retired general Walt Natynczyk ordering — in 2012 — a study that looked at the possible replacements.

University of British Columbia defence expert Michael Byers has been quoted as saying he's worried Canada "will lose its submarine capability through negligence rather than design," noting that it is politically more palatable to refurbish the underwater fleet rather than endure a painful procurement process.

"They're running a risk with the lives of sailors, the older these vessels get in an extremely dangerous environment, especially when they're submerged," said Byers, who pointed to the loss of the Argentine submarine San Juan and its crew of 44 in 2017.

"I would be more comfortable with a decision to buy a new fleet submarines than the current path that we're on. I have been skeptical as to whether we need submarines, but better a new fleet than send our sailors to sea in these old vessels."

Since Canada does not have the technology, nor has it ever constructed its own submarines, the federal government would be required to go overseas to countries such as Germany or Sweden to get them built.

Restricted diving

In the meantime, Haydon said he's confident ongoing maintenance and the stringent safety standards among Western allies will keep the Victoria-class submarines in the water and operating safely.

He cautions, however, like Canada's previous submarines retired in the 1990s, the Oberon class, the older the current fleet gets, the more their diving depth will eventually have to be restricted.

As the hull and its valves weaken, the less pressure they can sustain.

Lamirande said the navy has enough escape submarine suits whenever it deploys, and she emphasized it never goes to sea with "expired" equipment.

I will observe that the Sub Escape Suits are, I believe, a First Level System. 

The inspection and testing that they would have undergone to get recertified and shelf life extended by the Life Cycle technicians would have been very thorough, and any rubber seals found degraded when tested in the durometer would have been redirected into the disposal stream instead of renewing the shelf life on them.

The good thing about the sub buy is that they won't be built here. We should buy into another build *cough Aussie, cough* and keep the changes minimal.

Fire breaks out aboard hunter-killer submarine drydocked at CFB Esquimalt

https://globalnews.ca/news/5120237/esquimalt-submarine-fire/

This is all bad and all, but what I'm really interested in is this part:

HMCS Corner Brook has been at the base for an extended docking work period since January 2015, with an expected completion date of 2020.

A 5 year extended work period? How long would it take to build a similar size submarine from scratch? Honestly, I wish I understood what the hell goes on at FMF (and at the same time, for my sanity's sake I'm glad that I don't).

Actually I read something online about 2021. Its much easier to repair or overhaul something than paying capital costs for new ones. Any maintenance for submarines is involved and expensive.

Don't forget there are some unique issues to this one related to hitting the ocean floor...

Technically, it hit the ocean side. ;D

FMF has nothing to do with Corner Brook.  That one is all Babcock.

Good to know! Thanks. <turns and stares judgingly at Babcock>
