Huehen do you have any info about the new norwegian subs? Type 212CD?
It is rumored in Dutch naval forums that there are talks with the germans about joining the programme but i cant find any reliable info about the boats.
I have found info that they will be limited to +/- 1500 ton due to operations in the Fjords but i also found info that they would be arround 50% larger then the current Type 212's.
After my understanding they will be an improvement on Ula class, and Ula class was build to be able to operate in the open ocean, as well as in the fjords. and it's quit often they operate North of Lofoten, and all the way up to Svalbard. so I belive the 212CD would be an ocean going with enough flexibility to operate in the fjords. If Norway was only focusing on the fjords, we had gone Swedish. (when we are invited to exercise in US, Ula class, travel by it's own power over the pond. last time a Swedish submarine went over, it was transported on a ship, probably for comfort, for the crew)
after searching around on the Norwegian version of the Type 212CD submarines, the list is following:
- they are still working on finding partners and how deliver equipment for the submarines, and signing contracts.
- signing contract with the shipyard itself, first in 2019
- Service on Type 212CD both German and Norwegian, will be in Norway. if that include other German submarines in the 212-series, I don't know.
- the submarines are supposed to be in service, 2026-2030
- There are some technology, that are under development or will be improved for this class
- These submarines will be equipped with submarine version of Naval strike missiles. (development contract with Germany are already signed)
other than that, it is still to early. they haven't yet signed contract with the shipyard.
Thanks for the update, i still do no believe that Type 212CD is the way to go for the RNLN with its walrus replacement. The fact that they can sail across the ocean is good but ''we'' need a sub that can operate in the ocean for long periods (due to the caribbean islands). I was reading a Norwegian media site about the 212CD's and it was stated they could stay underwater for upto 18 days.
If i compare the range of the Ula class with our Walrus boats its a shocking conclusion that they cant be replaced by the same boat unless one of the navys changes course on its sub operations:
Ula : 5.000 nm / 9,300 km @ 8 knots
Walrus : 10,000 nm / 18,500 km @ 9 knots
The Type 212 is getting closer but still not enough as i estimate that the new boats will have a even greater range
212 : 8,000 nm / 15,000 km @ 8 knots
A26 Oceanic ER : > 10,000 nm / 18,500 km @ 10 knots
Also the dive depths are a big difference
Ula : +200 m
Walrus: + 300 m (official depth is classified)
212: 250 m / 700 m crushdepth
A26: 200 m
The problem is in the dive depth for the dutch cooperation between Damen / Saab, the walrus class uses a double hull instead of the A26's (and 212's) single hull.
Damen already hinted to a single hull for the new subs (cheaper) but if the navy requested a double hull it would be possible with the design.
