Germany will formally take delivery of its first NH90 MRFH Sea Tiger anti-submarine helicopter in Berlin on 16 December, bringing a new ASW and anti-surface warfare platform into German Navy service. The aircraft will replace aging Sea Lynx helicopters and deepen NATO’s ability to track submarines and protect undersea infrastructure in the Baltic, North Sea and wider North Atlantic approaches.
On 10 December 2025, the German Navy announced that its naval air arm will take delivery of its first NH90 MRFH Sea Tiger shipborne helicopter during a ceremony in Berlin on 16 December. The handover, in the presence of Defence Minister Boris Pistorius and Navy Inspector Vice Admiral Jan Christian Kaack, marks the operational entry of a new generation of anti-submarine and anti-surface warfare helicopter. Designed specifically for frigate operations, the Sea Tiger will become the primary sensor and weapon platform for German surface combatants in the North Sea, Baltic and beyond. Germany’s induction of its first maritime patrol aircraft and the Netherlands’ decision to acquire three additional NH90 helicopters, with an option for two more, mark significant steps in strengthening NATO’s posture in northern waters amid rising submarine activity and growing concern over seabed infrastructure security. The Dutch development was reported by Army Recognition, highlighting efforts to close a long‑standing gap in sea‑based aviation capacity.

The NH90 MRFH Sea Tiger is the most modern shipborne helicopter in German service, derived from the NATO Frigate Helicopter version of the NH90 and tailored to German naval requirements. It combines a composite airframe, full fly-by-wire flight controls and modern avionics with a mission suite focused on anti-submarine warfare (ASW) and anti-surface warfare (ASuW). For submarine hunting, the helicopter carries a dipping sonar and a launcher for active and passive sonobuoys, allowing the crew to build a detailed underwater picture around the escorting frigate. In the strike role, it can deploy MU90 lightweight torpedoes and MBDA’s Marte ER anti-ship missile, while electro-optical sensors and radar provide long-range surface surveillance and target identification.
This first delivery closes a development cycle that began when Germany selected the Sea Tiger in 2019 to replace the ageing Westland Sea Lynx Mk88A, which has formed the backbone of German naval helicopter operations since the early 1980s. Parliament approved the procurement in November 2020, and a contract for 31 Sea Tigers was signed later that month between the procurement agency BAAINBw, acting via the NATO Helicopter Management Agency, and the NHIndustries consortium led by Airbus Helicopters. The prototype made its first flight on 30 November 2023, followed by an intensive eight-week mission-system test campaign from February to April 2024 in Marignane, where the FLASH dipping sonar, sonobuoys, torpedoes and missiles were evaluated in realistic conditions. Subsequent flight campaigns and demonstrations at Nordholz validated the helicopter’s performance ahead of deliveries scheduled from late 2025 over a period of five to six years, as previously reported by Army Recognition.
Compared with the Sea Lynx it replaces, the Sea Tiger offers more endurance, payload and sensor range, as well as a fully digital mission system that fuses sonar, radar, electronic support measures and electro-optical data into a single tactical picture for the crew. Unlike the NH90 NTH Sea Lion already in German service, which is optimised for transport and search and rescue, the Sea Tiger is configured from the outset as a front-line combat helicopter, with its primary focus on submarine and surface-ship engagements rather than utility tasks. In capability terms it is close to, and in some areas more specialised than, other NH90 NFH variants in NATO fleets such as the French Caiman, but tuned to German concepts of operation and ship systems. By standardising on the NH90 family at sea and on land, Germany simplifies training and logistics while fielding a maritime helicopter that is fully interoperable with Allied platforms and datalinks.
Strategically, the Sea Tiger arrives as the Baltic and North Seas have become central theatres for undersea competition, with growing concern over submarine patrols, shadow fleets and possible sabotage against pipelines and seabed cables. Operating from Sachsen- and Baden-Württemberg-class frigates, the helicopter extends the ships’ sensor and weapons reach well beyond the horizon, reinforcing Germany’s ability to monitor and, if necessary, engage hostile submarines or surface units on behalf of the Alliance. In combination with the future P-8A Poseidon maritime patrol aircraft, the Sea Tiger will help deliver a denser, more continuous maritime situational picture for NATO from the North Atlantic approaches into the confined waters of the Baltic Sea, where critical European energy and data infrastructure is concentrated.
The Sea Tiger programme is one of the largest rotary-wing investments in the German naval portfolio. The Bundestag approved around €2.7 billion for 31 helicopters, including spares, training and support packages, placing the contract among the flagship projects funded under Germany’s recent defence-budget reinforcement. The aircraft are procured through NHIndustries, with Airbus Helicopters as the main industrial partner for the German configuration, following an earlier contract for 18 NH90 Sea Lion naval transport helicopters and a substantial fleet of NH90 TTH helicopters for the Army. Once deliveries are complete, 30 Sea Tigers will be concentrated at Naval Air Wing 5 in Nordholz, turning the base into a core hub for Germany’s and NATO’s shipborne ASW capability.
The handover of the first NH90 MRFH Sea Tiger therefore represents far more than the arrival of a new helicopter type. It signals the transition of the German Navy, and by extension NATO in the Baltic and North Sea, to a new generation of maritime air power in which advanced sensors, networked weapons and persistent undersea surveillance are central. As additional aircraft join the fleet and replace the Sea Lynx over the coming years, Germany will field one of Europe’s most capable shipborne ASW helicopter forces, reinforcing allied deterrence and helping to protect contested sea lanes and critical infrastructure from the surface to the seabed.
