The million dollar question: how private is "private" in China? Notice that unlike anywhere else (almost) everyone start with solid rocket motors these days, and in China it's not like you can go to a shop and buy them.https://twitter.com/AJ_FI/status/1121840523474624512 …
Also I don't think there are many launch vehicle start-ups that actually started with SRMs. Orbital was the only one that come to my mind; the only other one in the US that tried that route was the even earlier Space Services Inc. w/ Deke Slayton, which flopped.
In the 1990s there were a few in the US that did, or tried. Orbital, Lockheed LLV/Athena, Eprime with Peacekeeper motors, International Microsat’s Orbital Express, SSI->EER’s Conestoga (which flew an orbital launch attempt well after Pegasus & Taurus).
Well of these companies only Orbital and SSI would fit in the description of start-ups that made it to the "leaving the launch pad" stage. In China we already see 2 such companies flying in the past 6 months & a 3rd that may fly next month. Not to mention the state-owned ones...
You can’t compare the market in the early 90s to the current one.
That's correct. Yet it's also true that very few recent satellite launch vehicle commercial start ups anywhere in the world - be it in the US, Europe or other Asian countries - went with solid rocket motor solutions. Except the Chinese. The system there must be different.
