Reports Neptune being used as a land attack missile vs an airfield.
Yes, it's wiki, but only because I couldn't be bothered to dig out other references to the S400 system being taken out by Neptune.
"Credible" - given the number of missiles and drones of all types claimed to be launched by the Russians in each strike, and the number of claimed by the Ukrainians of shoot downs, I don't expect to see photographs of the wreckage of every missile destroyed. However, reported casualty figures that are often a few individuals suggest that Kinzhal is not routinely getting through Ukrainian air defence and hitting its target. If it is, they are being launched so sparingly that it is insignificant.
"Many of which have allegedly been shot down, or wasted on unimportant targets"
Your turn - citation needed. Who is making these allegations?
Because while I am sceptical about Ukrainian pronouncements, on a 'trust but verify' level, I treat Russian pronouncements as lies unless and until proven otherwise. As I have had cause to mention before, they were claiming to have destroyed more Bayraktar than the entire production run, claiming to have destroyed Bradley months before the first arrived in Ukraine, etc.
I am quite confident that the Russian Black Sea Fleet HQ is now a smoking ruin, since I've since the video posted by Russians on social media, who received so little warning of the strike that they were still on the street to film the results of the first strike when they caught the image of the second missile scoring a direct hit into the hole created by the first, straight down into the building basement.
That's not an unimportant target. (And it doesn't matter whether the BSF admiral survived or not - that's the fleet HQ hit on a working day with no significant warming - so that's the fleet staff that are now dead or wounded - the planners, comms experts, logistics guys, etc; much more important than just the admiral)
The burnt out wreck of the landing ship destroyed in dry dock was not an unimportant target.
The kilo class submarine (that the Russian's originally claimed had suffered only minor damage, but which had a hole blown in its deck, and a large hole blown out through the side of the pressure-hull) was not an unimportant target.
"Meanwhile, an increasing number of Ukraine's aircraft are being shot down by S-400s with improved missiles, or Russian aircraft carrying R-37 missiles, possibly improved variants"
Again - your turn... citation please
The Ukrainian's recently suffered the probably loss of two fixed wing aircraft on the ground, due to the use of extended range loitering munitions.But then, the Russians just lost 14 destroyed helicopters (burnt wrecks counted by satellite imagery) and some additional number damaged (likely >5) thanks to two 27-year old ATACMs.
What Russian air defence doing?
Where were these wonderwaffe new-and-improved S400?
I've seen no claim by the Russians or admission by the Ukrainians of an inflight loss of a Ukrainian fixed wing aircraft for a long time (whereas there have been multiple claimed and several confirmed Russian fixed wing losses in the last few weeks).
All of which points I find of great interest, but all of which are ultimately irrelevant to my original post of course, which was that Ukrainian defence industry is doing ok.
