Re: DDG 052C Thread
Any major upgrade of the 052C++ DDG from the previous 052C??
I am no expert on naval ships, someone could give me an insight.
Thank you.

Re: DDG 052C Thread
I think if you have liquid fuel based engine (like hydrogen/oxygen) it is possible to propel the missile in water.
Solid propellant engine is preferred for military ballistic missile because it provides larger thrust, does not need to be fuelled before launch, and also don't have a short expiration date (as the case with say hydrogen peroxide)
Solid propellant means they need oxygen to be present in the environment in which they are ignited.

Uh, no?

No. Rockets don't need air, that's why they are called "rockets".
Re: DDG 052C Thread
Solid propellant is a mixture of fuel and oxydizer that is cast into the rocket motor section. The oxydizer might be an oxygen-rich rubber, while the fuel might be finely dispersed aluminum. This was used long ago and might well be used still.
I'd hate to have cryogenic fueled missiles on board my submarine.

Re: DDG 052C Thread
Just curious, are nuclear ractors really that expensive compared to traditional engines? I mean, the Chinese already have those nuclear subs, can't they just modify them to place it on the surface combatants?
Another quick question is the nuclear submarines. We often see 3,4 conventional subs roll out of the dock every year, but we rarely see nuclear subs being produced even 1 per year. I have read a serious article, not those fan boy ones, but academic article, saying that even at the most conservative estimation, a nuclear attack sub would equal four conventional subs. Since China really want a blue water navy, why not just roll out nuclear subs instead of conventional ones.
There must be a reason why Russia and USA still only produce nuclear subs even 20 years after the end of the cold war.
