The baffles is the area in the water directly behind a submarine or ship through which a hull -mounted sonar cannot hear. This blind spot is caused by the need to insulate the sonar array, commonly mounted near the bow, from the noise of the vessel's machinery.
Light does not penetrate very far into the ocean, so submarines must navigate through the water virtually blind. However, submarines are equipped with navigational charts and sophisticated navigational equipment.
Hull mounted sonar is employed in addition to the towed array, as the towed array can not work in shallow depth and during maneuvering. In addition, sonar has a blind spot "through" the submarine, so a system on both the front and back works to eliminate that problem.

The ability to see above the surface is essential for surveillance, intelligence gathering, and reconnaissance missions, but early submarines lacked this capability. In 1898, to fire a torpedo, the Navy's first commissioned submarine, the USS Holland, porpoised. It surfaced far enough to expose the conning tower and aim the weapon, then dove. Witho...
For over 50 years, periscopes were the eyes of a submarine. However, the instrument's location in a sub wasn't ideal. Installed in the center of the control room, the bulky device took up valuable space on the cramped upper deck. Sailors manning periscopes walked around in circles looking for threats. Periscopes also penetrated a sub's hull, so col...
These masts continue to evolve. In 2015, L3Harris won a $48.7 million contract to provide slimmer, low-profile photonics masts on the Navy's Virginia-class subs. The Navy awarded L3Harris a $73.7 million contract in 2019 to repair, upgrade, and service the next generation of masts. "Routine upgrades of the sensors have improved performance through ...
Oct 19, 2023 · When a bright light, e.g., from a submersible or a photography flash, strikes these marine animals in their eyes, it can be incredibly intense and traumatic. Imagine going years without seeing any light, and then suddenly having your world flooded by it.

Soviet subs at the time didn't have that, and were essentially blind behind them. By staying behind Red October ("in their baffles") Dallas was effectively hidden. The "Crazy Ivan" turn was so they could check this blind area behind the ship.

Submerged submarines are generally blind to the actions of a patrolling aircraft [dubious – discuss] until it uses active sonar or fires a weapon, and the aircraft's speed allows it to maintain a fast search pattern around the suspected contact.
