Israel Takes Delivery of Advanced INS Drakon Submarine from Germany Amid Secrecy

Israel's navy has quietly taken delivery of its sixth and final Dolphin-class submarine, the INS Drakon, from Germany. The handover occurred in Kiel on July 22, 2026, without the typical public ceremony or official announcement, marked only by a police watercraft patrol. This discreet transfer underscores the unique nature of the new vessel.

The INS Drakon belongs to the Dolphin-II sub-class, but it represents a significant departure from the earlier INS Tanin and INS Rahav. While the exact modifications remain undisclosed, analysts note a substantially larger sail and an estimated increase in length from 68.6 meters to around 73 meters. These changes suggest increased internal volume and extensive structural redesigns.

Israel's Dolphin-class submarines, originally based on German Type 209 designs, have been progressively adapted and enlarged for Israeli naval requirements. The first three were delivered in the early 2000s, followed by the second series, which incorporated Air-Independent Propulsion (AIP). The INS Drakon's development began after its order in 2011, with construction starting the following year. Co-funded by the German government, the submarine's construction spanned 14 years, including a major redesign after its initial build phase commenced.

The extensive modifications, particularly to the sail structure, have fueled ongoing speculation among naval analysts regarding the submarine's capabilities and role within the Israeli fleet. The vessel's first voyage under the Israeli flag took place the day after its handover.
