COLOGNE, Germany – The technology promises to be a game changer: a torpedo-seeking torpedo fired by surface vessels for head-on intercepts, missile-defense style.
Yet after more than a decade of research, lead nations Germany and the Netherlands are still years away from fitting their navies with a hard-kill torpedo countermeasure.
Germany’s navy has been toying with a product called SeaSpider, developed by Atlas Elektronik, for several years. Work on the sole technology option under consideration in Europe goes back even further, with engineers studying it for at least 15 years, according to the firm’s website.
But while Atlas has tried to market the system as ready for combat, no navy has yet taken the bait, and the Dutch Ministry of Defence has repeatedly pushed back the start of a formal purchasing program based on SeaSpider.
The German sea service did tests some years ago, but decided against adopting the system. And the Canadian navy, deemed a prospective SeaSpider launch customer due to the timing of its large-scale surface combatant program, made no mention of the capability in its initial lineup of technologies for the future fleet.
A spokesman for Atlas’ parent company, Thyssen Krupp Marine Systems, declined to discuss SeaSpider, pointing to previous requests by the German navy to keep details under wraps. A spokeswoman for the German Ministry of Defense said the technology’s classification and contractual status prohibit the disclosure of details.
Still, officials in Berlin believe that a capability to intercept torpedoes with torpedoes is a critical force-protection technology in principle, the spokeswoman told Defense News.
Torpedoes have historically been one of the main threats to surface vessels, with the weapon involved in more than half of sinkings of U.S. Navy ships during World War II, according to U.S. Coast Guard data cited by Dutch researchers at TNO, a government-linked research organization.
Defense against torpedoes remains essentially a losing proposition, according to experts, leaving surface ships relatively vulnerable once such a weapon is headed their way. The main defensive measures consist of maneuvering, or launching decoys to confuse incoming torpedoes. Yet the latter is ineffective against so-called wake-homing variants, which align their travel path to hit ships in a straight line from behind, their sonar signature buried in the acoustic noise of a ship’s own propulsion system.
The U.S. Navy experimented with an anti-torpedo interceptor installed on three of its aircraft carriers in 2017, before uninstalling the system in 2018, saying that while the hard-kill measure showed “some capability to defeat an incoming torpedo,” reliability was uncertain and lethality of the system was untested.
SeaSpider can intercept all types of torpedoes, combining data from sensors installed on the carrier ship and the interceptor torpedo to compute collision paths with the inbound weapon, the manufacturer promises on its website.
The package has been in play again since last year for further development under the auspices of a European Union program, led by Germany and the Netherlands, labeled simply “Anti-torpedo Torpedo,” or ATT.
A one-sentence description for the project on an EU website describes a desire for “bringing a developed anti-torpedo torpedo demonstrator to the production-ready design, with a qualified effector and a proven functional chain,” an apparent reference to the Atlas product that only the Dutch Ministry of Defence would confirm to Defense News.
A spokesperson there said the SeaSpider technology is still too immature to warrant setting up a formal program, though Dutch defense officials have planned to take such a step, which requires parliamentary notification, since 2022. If it all comes to pass, perhaps in 2025, budget analysts have slotted a torpedo-killing torpedo capability into a category of programs consuming anywhere between €250 million and €1 billion, according to the Dutch MOD.
That is in addition to a related effort, led by TNO and estimated at €50 million to €100 million, to sharpen the technology for torpedo detection that would go into an eventual anti-torpedo torpedo suite, a spokesperson told Defense News.
Notably, the German MOD declined to disclose even the industry team of Atlas and TNO as lead companies of the European Union program, set up under the bloc’s defense-cooperation push known as PESCO. A spokeswoman in Berlin said no contracts had been signed in the matter.
Also unanswered were questions about the shortcomings that the German navy sees in SeaSpider. Defense News has learned that the depth of the envisioned intercept sequence is at issue, with the Atlas system currently limited to hits around the water surface.
In the end, the timing of a European anti-torpedo torpedo program could line up with Dutch Navy plans for new anti-submarine warfare frigates, the first of which is expected to become operational in 2029. That is because German officials expect the PESCO program to yield a production-ready system that passes all regulatory requirements by the end of the decade, with a prototype built in 2028.
In the meantime, other European nations also have taken an interest, including Sweden, Poland, Portugal, Italy and Spain, according to issue experts.
