The Ukrainian High Command and the Mayor of Odesa (fired from) said two Ukrainian Neptune anti-ship cruise missiles were fired at the Moskva.
I heard on MSNBC tonight that The Moskva was hit by missiles designed by Ukraine itself, not by ones supplied by foreign powers. I came to Debate Politics to see if there were any good threads about the sinking of the Moskva and was pleased to find this one. (Litwin also posted one, but Rogue Valley alluded to the missiles Ukraine used.) Here is some more information I found about the missiles. I can understand why the Ukrainians would be proud!
"What are Neptune missiles?
RK-360MT Neptunes are mobile anti-ship cruise missile capable of destroying targets within a range of 300 km.
The 16-ft long engine-powered missiles can travel at speeds of up to 560mph (900 km/h) and at heights of between nine and 30ft above the surface.
The weapons, which are able to be mounted on ships, by land and by air launchers, were formally adopted by the Ukrainian Armed Forces in August, 2020.
Weighing 870 kg and carrying a 150kg warhead, they are capable of destroying targets of up to 5,000 tons, using a radar-homing guidance to home in on enemy ships.
The blog BMPD run by Center for Analysis of Strategies and Technologies (CAST) an independent Russian research organisation, reports that one Neptune division normally has six USPU-360 launchers capable of firing a salvo of the 24 anti-ship missiles.
When did Ukraine get them?
In March, 2021, Ukraine beefed up its coastal defences against Russia when its navy obtained the first units of the cruise missile system.
The navy’s top commanding officer, Rear Admiral Oleksiy Neizhpapa, said at the time: “This system was designed to defend Ukraine in the Azov and the Black seas.
'This will be Ukraine’s missile shield in the sea.'
The Neptune system was designed by Kyiv-based defence manufacturer LUCH Design Bureau, from which Ukraine’s Ministry of Defence ordered its first batch of the missiles.
A project to develop the weapons was launched in 2014 after Ukraine lost nearly 80 percent of its naval vessels following Russia’s annexation of Crimea.
According to the Kyiv Post newspaper, Ukraine’s military had planned to put three divisions of Neptune cruise missile systems into service by 2025 along the Black and Azov seas coastline, with one of the batteries on permanent standby duty."
