Suojapuomeja näyttää olevan. Harvinaisen turha sotimisväline tuo ukrainalaisten vesijettidrone, jos se on torjuttavissa simppelillä öljypuomilla:
Sevastopol is now protected by two layers of floating booms at the harbor entrance. There are also newly installed booms across and around the main warship berths, and across Pivdenna bay where the submarine piers are. At the back of the harbor, where the refuelling piers are, ships are protected by yet more floating booms. Some of these booms were already present, mainly for environmental protection (to contain floating oil). However the operating procedures have changed and they are now routinely deployed.
Vesseli siis tökkää kumiseen, noin metrin korkeaan kelluvaan puomiin ja räjähtää itsekseen siinä, aiheuttamatta sen kummenpaa vahinkoa.
