Captain Han also recognized the unusual nature of this object; it wasn't a part normally found on conventional submarines.
Because the design of this tail section was completely different from those of conventional submarines.
He was still uncertain about which model's submarine propeller this tail section belonged to.
This thing seemed somewhat foreign to him, yet at the same time, it felt vaguely familiar.
Mainly because there are only so many places that can build nuclear submarines, and each is a treasured asset.
They are not easily revealed to outsiders.
They are each country's secret weapons.
Generally speaking, it is very difficult for others to see the full picture.
Since it is so hard to witness the full thing, naturally... the propeller of the tail section is little known.
Especially this tail section's propeller, which is a secret of nuclear submarines.
It can almost be said to be the most secretive part of a submarine.
