Submarine hull penetrators are critical components in modern naval defense systems, enabling the safe and secure passage of cables, sensors, and other vital equipment through the pressure hull of a submarine. These specialized systems are designed to maintain the integrity of the submarine’s hull while allowing for external communication, power supply, and the transmission of data without compromising the vehicle’s ability to withstand extreme depth pressures. These hull penetrators are essential for integrating advanced sonar systems, weapons control, and surveillance equipment into the submarine, ensuring both operational effectiveness and the vessel’s structural integrity in extreme underwater environments. As the technology continues to advance, the design and functionality of BIRNS penetrators have evolved to meet the growing demands of stealth, reliability, and security in modern naval operations.

BIRNS has a range of advanced configurations of military grade hull penetrator lines. High performance designs include CSI/SUBSAFE high density electro-opto-coax military grade submarine hull penetrators. Configurations are available with up to 161 contacts in inserts with an OD of < 2”.
