The German Navy received its first BlueWhale autonomous underwater vehicle at the Eckernförde naval base on February 25, 2026, a delivery that introduces a large unmanned underwater system intended for missions including anti-submarine warfare and underwater surveillance. The vehicle is built by Israel Aerospace Industries and integrated by ThyssenKrupp Marine Systems, according to the companies’ statements. The delivery falls under Germany’s “Kurs Marine 2035+” modernization program.
What the BlueWhale Actually Does
The BlueWhale is a large autonomous underwater vehicle capable of detecting targets both above and below the surface while collecting intelligence data, according to information released by ThyssenKrupp Marine Systems. That dual detection capability sets it apart from smaller underwater drones typically used for mine countermeasures or seabed mapping. The BlueWhale is built for anti-submarine warfare, or ASW, a mission set that has traditionally required expensive manned submarines or surface warships equipped with towed sonar arrays. Fielding an autonomous platform for this role means the German Navy can maintain persistent underwater surveillance in contested waters without tying up crewed vessels or exposing sailors to danger.
The practical effect is straightforward: a drone that can patrol independently, track hostile submarines, and relay data back to command centers changes how a navy allocates its limited fleet. Germany operates a small submarine force of six boats, and each one pulled off patrol for maintenance or crew rest creates a gap in coverage. An autonomous vehicle that fills those gaps, even partially, extends the reach of the fleet without requiring additional manned hulls. The BlueWhale’s sensor suite is not fully detailed in public disclosures, but the companies say it is designed to detect targets both above and below the surface.
Handover Ceremony at Eckernförde
The formal transfer took place at Eckernförde, home to Germany’s submarine flotilla, with Vice Admiral Jan Christian Kaack accepting the vehicle on behalf of the navy. TKMS ATLAS ELEKTRONIK Executive Vice President Michael Ozegowski and IAI CEO Boaz Levy were both present at the ceremony, according to the German Navy’s official announcement. The attendance of IAI’s top executive underscored the importance the companies place on the handover. For Berlin, hosting such a high-level delegation underlines that unmanned underwater systems are moving from niche experiments to core naval capabilities.
The handover followed a series of trials in the Baltic Sea, where the BlueWhale completed operational testing before being accepted by the navy. Those tests were intended to validate the vehicle’s performance in Baltic operating conditions before acceptance. Passing Baltic trials means the BlueWhale has demonstrated it can function in one of NATO’s most operationally demanding maritime environments, not just in controlled test conditions off the Israeli coast. It also gives German crews and engineers early experience in launch, recovery, and data exploitation procedures that will shape how the system is used in routine operations.
Germany’s Rapid Adoption Strategy
The BlueWhale delivery sits within the broader “Kurs Marine 2035+” program, which the German Navy uses as an experimentation and rapid adoption framework for new technology. Rather than following the traditional decade-long procurement cycle that has plagued European defense programs, the framework is designed to get promising systems into operational hands quickly so the navy can learn by doing. This approach is intended to get promising systems into operational hands quickly so the navy can learn by doing. For Germany, the program is framed as a way to accept higher technical risk in exchange for faster fielding and operational learning.
The exact number of BlueWhale vehicles Germany has ordered and the total cost of the program remain undisclosed, as noted in coverage by Defense News. That secrecy is typical for submarine-related procurement, where revealing fleet size or capability details could hand an adversary useful intelligence. But the deliberate silence also raises questions about whether this is a limited trial buy or the start of a larger fleet acquisition. If Germany orders only a handful of units, the BlueWhale will function primarily as a technology demonstrator and training tool, helping the navy refine operational concepts, doctrine, and legal frameworks for unmanned underwater operations. A larger buy would signal a genuine shift in how the navy plans to conduct anti-submarine warfare over the next decade, potentially reshaping requirements for future manned submarines and surface combatants.
Why Anti-Submarine Warfare Matters Now
The timing of this delivery comes as European navies and NATO allies continue to emphasize undersea awareness and anti-submarine warfare, amid broader regional security concerns. Germany’s submarine force, while technically capable, is small, and the surface fleet lacks dedicated ASW frigates in sufficient numbers to cover the Baltic approaches, the North Sea, and commitments to NATO standing maritime groups simultaneously. An autonomous underwater vehicle that can operate independently for extended periods offers a way to stretch thin resources across a wider area, especially in chokepoints such as the Danish straits and approaches to key ports.
The challenge for Germany, and for any navy adopting autonomous underwater systems, is integration. A drone that operates in isolation provides useful data but limited tactical value. The real payoff comes when autonomous vehicles feed real-time targeting information to manned submarines, surface ships, and maritime patrol aircraft, creating a networked kill chain that can locate, track, and if necessary engage hostile submarines faster than any single platform could alone. Whether the German Navy has the command-and-control infrastructure to exploit the BlueWhale’s full potential remains an open question, and one the “Kurs Marine 2035+” framework is presumably designed to answer through operational experimentation. Issues such as secure underwater communications, rules of engagement for unmanned systems, and coordination with NATO partners will determine how transformative the new capability actually becomes.
A Signal to NATO Allies and Competitors
Germany’s decision to source its first large autonomous underwater vehicle from Israel rather than from a European partner carries its own message. IAI has invested heavily in unmanned systems across air, land, and sea domains, and the BlueWhale represents the company’s push into a market segment that European defense firms have been slower to develop at scale. For TKMS, which served as the integration partner, the project offers a way to remain central to Germany’s undersea enterprise while tapping into foreign innovation. That division of labor could foreshadow future collaborations in which non-European firms supply core autonomous technologies and European shipyards handle adaptation to NATO standards, logistics, and lifecycle management.
For NATO allies, the BlueWhale’s arrival is a visible sign that Germany is beginning to invest in undersea capabilities that match its economic weight and geographic importance. A mature fleet of autonomous underwater vehicles could eventually contribute to alliance-wide surveillance networks, feeding data into shared maritime picture systems and easing pressure on overstretched U.S. and British assets. For potential adversaries, the message is more pointed: even without dramatically expanding its manned submarine fleet, Germany is positioning itself to make the Baltic and adjacent waters more hostile to covert undersea operations. How many BlueWhale systems Berlin ultimately buys, and how quickly it integrates them into NATO exercises and contingency plans, will determine whether this first delivery is remembered as a symbolic milestone or the beginning of a fundamental shift in European undersea warfare.
