[As at mid March 2015 the Netherlands' requirements remain unknown.]
Possible Swedish Role
While Sweden is building its own 2 - 5 A26s Sweden might build the 2 Walrus replacements or at least supply the components for assembly in the Netherlands.
5. Would the Netherlands find only 2 Walrus replacement submarines an effective number, given the "rule" of three and usefulness to the US alliance experience with the 4 Walruses.
6. Could the Netherlands continue to justify unusually large SSKs or scale down to the usual European country own use maximum of around 1,900 tons surfaced?
