The Borei-A Class submarines of Russia exhibit amazing advances in weapons capability and stealth technologies. By using sophisticated pump-jet propels rather than traditional propellers, these boats drastically lower their noise profile. Artificial intelligence in the submarine's combat information and control system integrates target detection and tracking automatically. It is almost invisible in deep seas since the better hull design combines innovative dampening technologies and sound-absorbing tiles.
