Yes.
I really like the thing , but what exactly do you shoot with it?
If it is accurate enough to shoot aircraft at long range it could be more useful than the weapons we have , but I doubt that it is that accurate.
If a ship is in line of sight or if a land target is in line of sight this would be devastating to it , but we are already devastating to targets in line of sight with naval guns and further than this with aircraft.
I wonder if this could be combined with super penetrator ammunition and shoot submarines at depth?
It is possible, that this is not a large increase in capability , in spite of a very large cool factor.
Now if it can do something not mentioned , there might be an increase in capability.
