Defence Blog – Ukraine’s navy sank a Russian border guard ship near Novorossiysk using an unmanned strike boat. The Ukrainian Navy said its sailors sank the Rubin-class patrol ship Izumrud (354), a Russian Federal Security Service border guard vessel, using the Sargan-3000, a domestically built unmanned surface strike platform that has entered service with Ukraine’s naval forces over the past year.
