Few Ballistic Missile Analysis w/ Aerospace-SIM - Part. 6 - Hyunmoo GrandSlam as ICBM (Hyunmoo Ultimate)?

 [See Previous Contents]


 

 Hyunmoo GrandSlam expected to deliver 8t warhead in 300km range is larger than its predecessors and weights about more than 40t. It is close to other solid-fueled 3 staged ICBM, and there is a possibility that S.Korea can modify Hyunmoo GrandSlam as a ICBM. 

 It means that last 3rd stage should be packed in 8t weight which was weight of simple warhead. Let's find out does it make sense or not. 


--- ICBM

4. Hyunmoo GrandSlam as 3 stage rocket

 There is a slight increase (41.4 -> 42.1t) of TOW (42.6t for 1.0t warhead), but basically same rocket motor can be integrated to 3rd stage for more range w/ smaller warhead (0.5 and 1.0t)




Summary

- It is a WHAT-IF missile that Hyunmoo-GrandSlam adopting 3rd stage rocket instead of 8t warhead, calling it "Hyunmoo Ultimate"

- 3rd stage is assumed as that of 2nd stage to save development time (but usually developing explicit 3rd)

- Result of 1t warhead is not much different when the GrandSlam just change its warhead. 

- 3rd stage w/ 0.5t warhead truely become the Major ICBM level. 

- Compare to North Korean's Hwasong 15 and 17, Hyunmoo-Ultimate is very compact and has operation advantage due to its fuel type if Hyunmoo adopted 3rd stage.
