PETE COMMENT
Some in the Australian Navy are looking at a modified (read, enlarged) TKMS Type 214.
But South Korea (with Indonesian export experience) is even more advanced in building larger German style subs.
Maybe if an "interim sub" for Australia is sufficiently enlarged:
- TKMS could call it the Type 216 again (history repeating itself)
OR
- South Korea could call it the already being built 3,000-4,000 tonne KSS-III (aka Dosan Ahn Changho-class submarine).
