On 28th March the Bramhos Block 3 with the new steep dive algorithm was tested. As far as I can see there is no air defence system in the world currently capable of stopping the Block 3. At 290 km max range, the missiles travel time is approximately 300 seconds assuming it reaches mach 2.8 within the first 10 seconds. This video pretty much confirms it IMO. By the 10th second the missile has disappeared. We can only speculate at what range the missile enters steep dive mode but irrespective, it is impossible for any air defence to intercept this missile before steep dive. To intercept the Bramhos before steep dive the air defence missile must have a speed much higher than the Brahmos to reach it before it starts the dive. There is no such missile that would be capable of this feat. We cannot take the THAAD, which in my opinion is the most advanced anti ballistic system, but like the name says it is a High Altitude air defence system. Even if it were capable of low altitude intercepts, assuming the Bramhos started its descent at half its range, i.e. about 150 km, it gives the THAAD approximately 160 seconds to take it down. That would be detecting launch, acquiring the target, firing the missile and covering a range of 150 km in 160 seconds. I cannot see how that is possible especially with ship based radars taking time to detect the launch, ie, the Bramhos has to actually reach a certain altitude before the air defence radars come within line of sight of the missile and the target is acquired. Dedicated naval air defence systems on the other hand do not reach anywhere close to the speed of the THAAD and hence cannot cover the range in time. Additionally they have range limitations and are designed for closer intercept ranges of between 50 and 100 km. Hence there is no way the Bramhos can ever get intercepted pre steep dive mode. Once in steep dive however the air defence radars are again blind, upto ... wait for it 20 KM on the most advanced systems at the altitude that the Bramhos is approaching at, which btw can be as low as 10m in sea skimming mode. At 20 km distance when the air defence system acquires the target, they have exactly 20 seconds to shoot it down because the Bramhos is coming at them at 1km/sec. The PLAN destroyers have the HHQ-9, the Chinese naval version of the S-300's. Good luck PLAN.
