On Tuesday, the Russian defence ministry said that Russia's navy fired supersonic anti-ship missiles at a dummy target in the Sea of Japan.
"Missile ships of the Pacific Fleet fired Moskit cruise missiles at a simulated enemy sea target in the Sea of Japan," it said on its Telegram account.
The target, located around 100 kilometres (62.14 miles) away, was successfully struck by two Moskit cruise missiles.
The P-270 Moskit missile, also known by its NATO reporting designation SS-N-22 Sunburn, is a medium-range supersonic cruise missile of Soviet manufacture capable of destroying a ship up to 120 kilometres away (75 miles).
The firing of the missiles comes a week after two Russian strategic bomber planes, capable of carrying nuclear weapons, flew over the Sea of Japan for more than seven hours in what Moscow said was a "planned flight".
