Submission Statement

Stratolaunch has been around for a while. Way back in 2011, they were a contender with SpaceX to launch the earliest iterations of the Falcon rockets. While this aircraft was initially developed to launch rockets into space. Presumably, that hasn't worked out, but they see another opportunity - hypersonic research. China seems to have taken a lead in that, which must be funneling US DoD money in that direction.

I wonder will anyone ever crack the nut that is a successful horizontal space launch from aircraft? Virgin Galactic tried in recent weeks and failed. Using this approach for small payloads of 500 kg or so seems most likely to succeed. Among the many problems this approach has, is that building rockets (that are mainly fuel containers for their small payloads) that can take both horizontal and vertical stresses is hard.

The statement about hypersonics might be misleading

China uses hypersonic boost glide vehicles, basically a rocket that propels to hypersonic speeds, nothing new, hypersonic speeds have been achieved in the 40's already when looking at rockets reaching orbit

The US has two working prototypes for a hypersonic cruise missile, which are much much more sophisticated because it uses air breathing engines to propel the missile

I'm not an expert on any of this, but many US military figures have commented the Chinese craft exceeds US capabilities.

Also, it can stay in orbit in space with nuclear weapons for prolonged periods of time, before re-entering Earth at hypersonic speeds - so this isn't something that anyone has been able to do before.

The X-37 is literally able to stay in orbit for a very long time, with the ability to carry nukes. It was first introduced in 2010, so it's not something never done before lile you said

Yes, but it glides in to land at a leisurely pace, and would be easy to shoot down.

The danger with craft at hypersonic speeds is that they are almost impossible to shoot down or defend against.

What? You know that it can drop nukes if it needs to, there is no need to re arm them because those are nuked we are talking about

Also, if china uses a missile, it needs to produce a new one, the US could drop the load AND make it land, reload and take off again

Hypersonic missiles can be intercepted, it will get easier with laser weapons
