Difference in fuel as well as engine. Agni does make use of Solid fuel and NoKo missile does make use of liquid. In the pic you have posted, you might see a black jacket around the orange flame. It is the shoot particles which generally indicates a lower burning temperature of the fuel.
Its because HS-12/14 have Liquid-fuelled 1st stage while Agni V is fully solid-fuelled. There's no smoke either. It was not until recently known that, Hwasong 12/14 actually have smuggled erstwhile Soviet Union's RD-250 engine. RD-250 is one of the few engines in the world thats Liquid-fuelled BUT doesn't needs to be fuelled up with a fuel truck. Its storable like the solid fuel and can be launched immediately just like other solid fuel missiles.
If you are looking for short answer than UDMH/N2O4 liquid fuel is the reason of that flame color in North Korean missile.
Yes, its ICBM and can cover as far as 9000km. NoKor currently holds the record to develop ICBM in shortest span of time w.r.t their ongoing (now scrapped) MRBM project 2 years back.
What is the range of it?
Excellent.....I always wondered why DRDO had not developed bunker busting missiles....
It means Pralay is having a CEP of 1 m or even less? Or would it be just BCES warhead.
Pralay is a hypersonic ballistic missile, no way it could have 1m CEP
But what is the need of this type of missile when we already have shaurya for this role....
If it would not have that much of CEP, then its bunker busting role would be minimal. If not less then 1m, then it would have to be anywhere in between 1 to 5 mtr CEP. Anything more then 5 mtr would not be considered an accurate system for this role.
Unlikely. If it is so, then it would be a back evolution. Shaurya is a QBM with 700 km range, whereas Pralay is reported to be a SRBM with 500 km max range.
