The Russian Black Sea Fleet flagship, the Moskva guided-missile cruiser, sank in the Black Sea on Thursday.
During a public address on Thursday night, Zelenskyy thanked those who showed that Russian ships can go to the bottom.
The site of the Moskva's shipwreck was described as a worthy diving site by the minister of defense of Ukraine.
He added that they have one more diving spot in the Black Sea, with an image of a deep-sea diver swimming alongside a turtle.
Lesia Vasylenko poked fun at Russian forces on Thursday, saying that it was part of the submarine fleet.
The biggest Russian ship to be sunk in action since World War II is the Moskva.
Russian officials confirmed on Thursday that it had sunk, but denied that Ukrainian border guards hit it with anti-ship missiles.
The crew of the Moskva was forced to leave after the explosion, but both Russia and Ukraine offered different explanations.
The state-run RIA Novosti reported that the defense ministry of Russia said that the ammunition exploded due to a fire. The ministry said the cruiser ship sank in the storms.
The explosion and sinking were caused by the missile strike.
Jake Sullivan, US national security advisor, said on Thursday that he was unable to confirm what caused the explosion.
Sullivan told the Economic Club of Washington, DC that they had to choose between incompetence and the fact that they came under attack.
