$12-70bn? Man, how do I get into submarine making business?

Anyway, does anyone know what makes a submarine "high tech" ?

why do you think military sub marines are easy to build and there is no / not much progress there?

In this case the highest tech on offer is AIP, "Air Independent Propulsion" tech that Germany is a leader in, which uses hydrogen fuel cells to allow for the sub to remain submerged for weeks at a time. The benefits are huge, unlike a typical non-nuke sub you get some of the benefits of a nuke plant, with the benefits of a much smaller, cheaper, easier-to-run vessel. The AIP is also extremely quiet, more so than even a well shielded nuke plant, so this style has real advantages for hunter-killer subs.
