OVERVIEW: The Dolphin II [Type 800 Mod] is a diesel-electric submarine operated by the Israeli Navy, representing a modification of the Type 800 class. It entered service in 2016.

DETAILS: The Dolphin II [Type 800 Mod] represents a significant upgrade to the original Dolphin-class submarine, incorporating advancements in stealth, sensor technology, and weapons capabilities. The design likely reflects lessons learned from operational experience with earlier Dolphin submarines and responds to the evolving strategic environment in the Eastern Mediterranean and beyond. While specific details of the modifications remain classified, the observed sensor suite suggests an emphasis on improved situational awareness and targeting precision in complex littoral environments. It is believed that the Dolphin II Mod was tailored to meet the specific operational requirements of the Israeli Navy, potentially including modifications for extended patrol endurance and enhanced special operations capabilities. The decision to upgrade rather than build new submarines likely reflected a balance between cost-effectiveness and the need for modernized underwater assets.

The Dolphin II [Type 800 Mod]'s primary roles encompass anti-submarine warfare (ASW), anti-surface warfare (ASuW), and intelligence gathering. While lacking a dedicated air-defense capability, the submarine’s inherent stealth allows it to operate effectively in contested waters. The submarine's ability to launch both 533mm and 650mm torpedoes provides flexibility in engaging a variety of targets, from surface combatants to other submarines. The Elta Navigation system provides precise positioning information critical for navigation in restricted waters and for accurate weapon delivery. The presence of both hull-mounted (CSU 90 Hull) and flank array (CSU 90 Flank) sonars, in addition to the towed array sonar (IPS CSU 90), indicates a layered approach to underwater surveillance, maximizing detection range and minimizing blind spots.

The installation of the Timnex 4CH(V)2 electronic support measures (ESM) suite significantly enhances the Dolphin II [Type 800 Mod]'s ability to detect and classify radar emissions from surface vessels and aircraft, providing early warning of potential threats and supporting intelligence gathering efforts. The MAS 90 system would give active sonar capability to compliment the passive sonar systems. The combination of a conventional optical periscope and a low-light television (LLTV) periscope provides redundancy for visual observation and targeting, particularly in low-visibility conditions. The signal ejector could be used to deploy decoys, underwater communication devices, or other specialized payloads. The 650mm torpedo tubes offer compatibility with larger, potentially more advanced weapons, while the 533mm tubes allow for the use of standard NATO-compatible torpedoes and anti-ship missiles.
