Saab Kockums Concept Proposal of Three A26 SSK Variants

Kockums, since it returned to Swedish ownership (bought by Saab) in July 2014, has been trying to find foreign buyers for the A26 and variants. In 2014 a variant concept was the 4,000 ton Type 612, which Kockums attempted to market to Australia in the future submarine (SEA 1000) competition. France's DCNS (now Naval Group) won the Australian competition. 

So Saab Kockums is still searching for foreign customers, but, the market has many competing submarine suppliers. Kockum's is now attempting to sell the A26 in three sizes.

Navyrecognition provided details on August 31, 2017 concerning Saab Kockums concept proposal of three A26 SSK variants (illustrated at Artwork A. below).

Pete Comment/Background

Using the Saab via navyrecognition details the three A26 variants in Artwork A consist of:

The "Pelagic" (Open Sea) variant can perhaps relate to Baltic, Mediterranean, Arabian and Caribbian Sea use. This variant is small – 50m long, about 1,000 tons (surfaced), 4,000nm range at 10 knots. Endurance at patrol speed is over 20 days assisted by the AIP module. Standard complement is 17 to 25. Saab Kockums may have the best chance of selling these small submarines to smaller navy customers including those who use subs for non-state threats, eg. Canada and Latin American countries in alliance with the US countering drug smuggling.

The Oceanic variant is the "baseline" A26 with two being built for the Swedish Navy. A26 Oceanic is 65m long, around 1,900 tons to 2,000 tons (surfaced), range over 6,500nm at 10 knots. Endurance at patrol speed is over 30 day assisted by the AIP module. Standard complement is 17 to 35. [Presumably around 10 Special Forces can be accomodated?]. I assume four A26 Oceanic variants of approximately 2,300 tons (surfaced) are being offered to the Dutch Navy as Walrus replacements.

The Oceanic (Extended Range) variant is a stretched version A26. It is longer than 80m, over 3,000 tons (surfaced). Range is over 10,000nm at 10 knots. Endurance at patrol speed is over 50 days assisted by the AIP module. Standard complement is 20 to 50. [Presumably around 10 Special Forces can be accomodated?]. 

Saab Kockums will have a battle selling the Oceanic and Oceanic (Extended Range) variants given TKMS is already established selling larger than the usual (1,800 ton submarines) to Israel, Singapore and designs to South Korea. India may be the best remaining slightly large  submarine customer under Project 75I.

If the Dutch are looking for similar range to their existing, then they would need the extended range version unless the only difference between the 2,000t & 2,300t versions is fuel. Current Walrus class is 10k nm @ 9knts. Your specs for extended range version is 10k nm @ 10 knts.
