Ukrainian scouts disabled the Baltic fleet trawler "Aleksandr Obukhov" of the Armed Forces of the Russian Federation.
This was reported by the Main Intelligence Directorate of the Ministry of Defense of Ukraine.
The ship was based in the city of Baltiysk and was supposed to go on combat duty, but it was severely damaged.
"Due to the mysterious appearance of a hole in the gas pipe, water got into the engine and Obukhov suffocated," the HUR reported.
It is noted that the Russian trawler now needs major repairs.
"This may turn out to be a serious problem - a damaged M-503 engine is a rather scarce thing. Repairing a key installation on a ship is technically difficult and expensive," the intelligence officers add.
The decommissioned ship underwent repair work in St. Petersburg in July this year.
