China Ballistic Missiles and Nuclear Arms Thread

LOL it says "Debang Transfer Co."

This supports my theory that modern Chinese nuclear warheads use U-235 pits instead pu-239.

The Plant’s history remains somewhat opaque, but the facility was built as part of the third line industries in the mid-1960s and likely began producing enriched uranium in

. It has been difficult to determine the current status of Jinkouhe. China reportedly stopped producing HEU for weapons in 1987, but China does not openly discuss the Jinkouhe GDP. Some analysts have assumed the plant is no longer operational, but as Zhang notes, local press accounts suggest the plant is still operational. China may still enrich uranium for military purposes, including fuel for naval reactors.

As the article mentions, the plant might be enriching HEUs for Type 093 SSNs and Type 094s' naval reactors than for bombs, as China is likely to rapidly expand its nuclear sub fleet in the near future.

Improvements on DF-5B vs. DF-5A ... ...






How accurate is the assessment below ?

1: DF-5B has Solid pre Launch fueling process, thus it can launch anytime in silo.

2: After pre-launch, the next stages are all using Liquid fuel propulsion,
... ... meaning it can control its ignition during the later flight stages,
... ... thus creating an Unpredictable Flight Path which is difficult to defend.

3: The drawback of all--stages--Solid--fuel missiles are ...
one can NOT control their ignition during their flight.

Meaning, once a Solid fuel is burning, you can NOT stop it.

Is the above assessment accurate ... ?

--------------------------------------------------------

4: Just in case the 1st Ignition device is malfunctioned.
... ...How many redundant auto--take--over ignitions devices does DF-5B has ?

Main difference with DF-5A he get 3 warheads 200/300 kt vs one big 4/5 Mt.

and all stages still liquid fuel ?

"Solid pre Launch fueling process" ?

What does it mean? Does it mean first stage is solid? Or the stages are fueled with a "solid" fuel tank pre-filled with liquid fuel? Or the stages are filled with storable liquid fuel?

 

[GreenestGDP]

The 1st stage or the Launching stage is using Solid fuel propulsion.

The subsequent stages are all using Liquid fuel propulsion.

Thanks. What is the main benefit having solid fuel in the 1st stage ? rapid reaction ?

Solid fuel has higher energy density, is easier to maintain, and the 1st stage canbe burnt to the end, no need for variable thrust.
