I see these numbers and to be honest, I don't doubt them but wow!
"The 'Oniks' missiles are originally designed to target surface ships, with a speed exceeding 3000 km/h. As a result, they are difficult to detect and intercept," he said.
The same applies to the "X-22" missiles, which travel at speeds over 4000 km/h.
Most risible about that is the fact that just earlier they claimed to be routinely taking out Russian Kinzhal missiles which are said to travel upwards of Mach 10.
I was the fire control officer on a frontline destroyer during the cold war. It wasn't much of a weapon system but it did work. and worked well. I look at those numbers and think back to the 'good old days'.
If you have something targeting you inbound at 3000 kph it is detected at the horizon by my fire control systems and hits the ship about 6 seconds later. Missiles moving at mach 10 are just invisible.
I really hate to say it but the USN has Harpoon missiles, subsonic sea skimmers that they are and for some reason the word toast springs to mind. I knew that when Soviet frigates were launching carrier killing missiles from the Black Sea at targets in Syria.
The USN will not win a naval war with Russia. It would do well to see who else has been buying those weapons because to be honest, it will be an ugly and short war.
