Next generation submarine type A26 The new generation, denominated A26, will be designed for mainly littoral operations but will also possess ocean-going capabilities. It will be powered by a conventional diesel-electric propulsion machinery, and equipped with Kockums Stirling AIP system (air-independent propulsion). The Stirling system, together with a set of balanced underwater signature properties, will make the A26 submarine very stealthy and difficult to detect. It will also be highly invulnerable to underwater explosions through a verified shock resistance. The A26 design includes a new innovative flexible payload capability with a flexible payload lock system in addition to its conventional torpedo tubes. Furthermore it will be prepared for network connectivity. A highly modular design facilitates efficient through-life upgrades and adaptations.
