GoalKeeper;
The system's reaction time to a Mach 2 sea-skimming missile such as the Russian SS-N-22 Sunburn from automatic detection to kill is reported to be 5.5 seconds with the firing synchronized to start the engagement at a range of 1,500 m and ending with a kill at 300 m.[2]
The SS-N-22 (russian version) has a 2.6 ft diameter, while the railgun `pellet` appear to be a few inches only, thus being much harder to hit. Also, final speed of the railgun pellet should still be much higher than mach 2. And at the range-speed combo they are talking of, the trajectory should be relatively flat. I'd bet against the goalkeeper.
