Pictures of US Glide Breaker program for space-based anti-hypersonic weapons and sensors

Michael Griffin, defense undersecretary, gave a rough estimate for deploying space-based interceptors can be calculated on the $20,000 per kilogram is costs to send material into low earth orbit. Thus a force of 1,000 space-based interceptors each weighing 1,000 kilograms would cost $20 billion.

Pictures for an anti-hypersonic weapons program called glide breaker have been released.

There was also a graphic illustrating how space-based sensors and interceptors would conceptually operate.

SpaceX is currently using block 5 Falcon 9 rockets. The block 5 first stages could be re-used dozens of times. The first stage is 70% of the rocket cost. SpaceX is also close to recovering the $6 million nose cone farings.

If the US military purchased 100 launches to launch ten one ton space-based interceptors each launch they could get a volume discount for the launches. Although NASA and military launches tend to be two or three times as expensive as regular commercial launches. Instead of double the cost the price might be 1.5 times the $62 million launch cost of a regular Falcon 9.

This would $90 million. Thus 100 launches would be $9 billion.
If they could fill up a Falcon 9 with interceptors with less overhead weight for delivery and storage equipment then as many as ten interceptors could be deployed per launch. This would bring the launch cost down to $4.5 billion.
