alt Hacker NewsAnyone who describes hydrocarbon fuels and high-test peroxide oxidiser as a stable and proven combination is a charlatan trying to sell you something questionable. If you want a proven liquid fuel combination that works in missile environment conditions with well-behaved ignition, Hydrazine/UDMH+N2O4 is the king.
Solids are better from a storage and deployment standpoint in almost all cases; anyone making a sincere case for liquid fuels should be making it on the basis of munitions that are best designed around them (notably, of course, most of the long range cruise missiles that have received the most hand-wringing about stockpile depletion are already air-breathing jet-fueled). The actual stockpile issues wrt solid rocket fuel are high-performance SAM/ABM interceptors, and those would require complete redesigns to make liquid-fueled equivalents.

The article says this. Liquids are better from a production perspective. In the Cold War, storage and deployment dominated. That need isn’t gone today. But it’s supplanted in priority by the need to be able to rapidly produce these munitions.

Again, the article acknowledges this. It’s saying we can do that faster than we can get another AP production facility online, and even then, we’d still be unfavorably production constrained compared to China.
