A weapon launched from space is hypersonic by definition, the X-37 itself travels at hypersonic speed all the time and moves faster than these missiles. The X-37 is very hard to track because it can make dramatic orbit changes using the earth itself as cover and appear from a different direction. It's all theoretical but a weapon like that launched from space is going to accelerate faster (it's already hypersonic when it comes off the rail) & generate less heat signature until it re-enteres the atmosphere. And if carrier groups can be sunk by these missiles it would make way more sense to have them on a space platform or a submarine platform than on ships.
