FELEX - Halifax Class Modernisation

[dapaterson]

I suspect that given the tensions in the aerospace sector, Brazil would not be interested.

 

[Oldgateboatdriver]

Perhaps, but the Niteroi's are getting to the end of their life and Brazil is going through a difficult economic time, so some times you put differences aside.

Besides, while Embraer is making noise like they are mad about the loans/funding to Bombardier, you may have noticed that the Brazilian government is not picking up the fight, except in the most subdued of ways, as it probably is getting the advice that there is nothing against the international commercial rules going on and they would lose (especially if their own participation in Embraer came to light ). Moreover, Embraer and the government of Brazil know that their competing airplane is not as technologically advanced (and in particular nowhere near the fuel economy and silence) as the C-Series and that the contract was won just as much on technology as price.

Bit-o-thread necromancy, but this puts a bow on the HCM/FELEX quite nicely at least from an engineering perspective.

This issue of the Maritime Engineering Journal is not a bad read if you're into that sort of thing!  Even comments from the shipyards on lessons learned, challenges and solutions.

great read, Underway.  Thanks for this!

Interesting the issue of cable management, the devil is very much in the details

Not sure if this falls into FELEX, HCM, or other, but interesting nonetheless. I believe this is the same radar selected for the JSS:

Saab Sea Giraffe Radar selected for Canada's Halifax-class frigates - Naval News

Saab has signed a contract for multi-role Sea Giraffe AMB naval radars antenna kits, for the upgrade of the Royal Canadian Navy’s Halifax Class frigates. The contract also includes associated equipment and spare parts with an order value over SEK 300 million (USD 32 million).

The HFX version of this radar is an upgrade of the SG-180 that is currently fitted on the HFX Class. The antenna (and its associated environmental systems) is the only thing being replaced. The rest of the radar below decks will essentially remain the same with some small adjustments due to the 3D nature of the new Ae (like processing cards and software).

JSS is getting a full bottom to top AMB, not a hybrid.

This radar was selected for the JSS with the anticipation that the HFX fleet would get it afterwords. But projects being what they are the HFX one was moved up and the JSS one was delayed. Either way, there will be quite a bit of commonality in the fleet. Also, the new AMB being a 3D radar will improve tracking for data fusion on targets which will improve PKill for weapon systems. The AMB is also very good for the SAC as it's going to give them better information about the ship's helicopter. That's one of the reasons it was selected for JSS over other radars.

So wasn't sure where to put this but the UWSU (underwater warfare suite upgrade) is in full swing for the CPFs.

VDQ has theirs fully installed and the West Coast is getting their first ship with it right now (or soon).

New tail (passive and active sonar vice just passive), new sonoboy reciever antenna, new hull mounted sonar, full upgrades to all the processing systems (half the size of the old systems) and some new interfaces in Ops.

This is a big change, and looks to really increase the power of the ASW side of the ship overall.

Underwater Warfare Suite Upgrade protects sailors from quieter submarines and torpedoes

The naval operational environment is constantly in flux, and small advantages can be the strategic difference during an engagement.

Old article on the project. The image shows the new tail, with it discrete elements. Good explanation of the project.

I got a bit of info from the previous LCMM and have heard from some folks that there is goodness involved in the results, but the trials are ongoing.

As a former SONAR Tech, I have a strong appreciation for what's being improved, and how.

There is going to be so much space in fwd and aft SIS now! The size and number of cabinets is going down by half. I expect fwd SIS to replace FCR 3 as the "lounge and play video games" space. Lol

Is this part of the CMS Refresh ?

 

[Colin Parkinson]

Any of this going to bleed into the CSC program technology wise?

 

[Oldgateboatdriver]

I suspect it was the other way around, Colin. That tech was probably looked at for the CSC's and found to be mature enough and adaptable enough to set up on the HAL's immediately.

 

[NavyShooter]

It was deliberately kept separate from the CMS refresh process.

Good.

 

[Underway]

CMS refresh is a tech refresh for CMS only. The UWSU is a completely different program.

Any of this going to bleed into the CSC program technology wise?

No as this program has its roots in DRDC research with industrial implementation going to GE not Ultra.

Just thinking, if you're looking for this program to "bleed" anywhere then the unfunded Corvette program may be a place for it to go. Or a least parts of it.

Most of what I've heard (all anecdotal) is that this is exactly what's going to go on the CSC.

AFAIK the CSC is getting a variable depth sonar from Ultra Electronics so it can't be exactly the same thing. The UWSU has a towable reel-able array (similar to the CANTASS but with active sonar transducers as well). Might be a lot of overlap though on the processing side even if the end sensor is different. I doublt the HMS is the same, one is a bulbous bow fitting and the other is a sonardome.

The other place that might be the same is on the CMS side. CTI might be a recycle of the UWSU interfaces for ASW.
