SVO News, December 15, 2025, Avia.pro. Ukrainian submarine kamikaze drones, the Sub Sea Baby, may pose a significant threat, according to experts, thanks to their stealth and ability to attack ships and submarines from several hundred kilometers away. These drones, developed by the Security Service of Ukraine (SBU), demonstrate the potential for conducting operations over significant distances, enhancing their strategic role in the conflict. Currently, Ukraine claims to have downed the Russian 636.3-class submarine Varshavyanka in the port of Novorossiysk, as previously reported. However, the Russian side has not yet provided an official comment, leaving the incident in question.
Given the recent incidents with Sea Baby surface drones and their successes against the courts, the development of underwater versions increases concerns.
