Air-Independent Propulsion

[U-533]

Turks with subs:hmm:

The Turkish Naval Forces has recently initiated a process to purchase six submarines with the highest technology possible.

The submarines are to include an "air-independent propulsion" system and will be able to roam under water for 50 days and will be difficult to detect due to stealth technology, which currently grants several military vehicles ghostlike mobility.

Stealth subs at that:hmm:

This should prove intresting.
