“The German military intends to start the procurement process for a novel “Anti Torpedo Torpedo” in 2026, according to a budget planning document published by Politico Europe on Tuesday.”
I first reported on this system in September 2024. French and Turkish companies are also apparently attempting to develop an anti-torpedo torpedo. Russia has long claimed that their light weight torpedo had hard-kill anti-torpedo capability. In April 2025 we had a report that the Netherlands had decided to purchase anti-torpedo torpedoes. In May 2025 we got an indication that the system the Netherlands was intending to use was the German SeaSpider.
The US counterpart anti-torpedo-torpedo is the Mk58 Very Light Weight Torpedo, also known as the Compact Rapid Attack Weapon or CRAW. In July, Naval News reports its status here. 168 US ships equipped with Nixie are expected to get this system which I believe would include some Coast Guard cutters.
I also hope to see the M58 equip large numbers of cutters as an anti surface weapon that would give cutters to ability to forcibly stop even large ships.
The Mk58, like the SeaSpider might also be usable against Unmanned Undersea Vessels.
