My new obsession is STM's 500 ton mini submarine. I wonder if they will use lithium ion batteries in the new sub.
So you won't need bulky and dangerous pressured hydrogen, oxygen tanks. Japanese has already made new sub with lithium ion batteries which doubled range,speed and lifecycle of batteries.
Recharging lead batteries is too long also you can't recharge them submerged as charging causes toxic gases.
@Anmdt Dear again me asking
What do you think about Italian DG-160 midget submarine design? It could dive 150 meter with 9 crew and carries 2 torpedoes. It has great range also thanks to midget weight to hard to detect.
AFAIK , in the heavy sea conditions, 150 meter deep is enough to avoid storms for submarines ? So 160 ton midget submarine would be reliable and effective for Turkish Navy?
They could complete FAC and Patrol roles without being noticed.

Postwar ERA German Subs weighted 500tons.
New lithium ion battery technology would bring great opportunities for midget submarines.
