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

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 (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.
