Few Ballistic Missile Analysis w/ Aerospace-SIM - Part. 4 - Hyunmoo IIC, IV-1, and GrandSlam

 [See Previous Contents]

Aerodynamics Series

 

 ROK developed GtG missile as the name series of Hyunmoo although Hyunmoo I is transformed version of Hercules missile. Recent Hyunmoo II ~ IV shows powerful tactical performance in relatively short range because their missiles are in missile-performance treaty. 

 Hyunmoo II A/B are very similar to Iskander-M series I hope you see this at the previous articles. From Hyunmoo IIC, it has their own identical performance compared to its predecessors. 

 While Hyunmoo II C is similar to Pershing II, Hyunmoo IV and 8t-Bunkerbuster are very interesting. 

(Hyunmoo III is cruising missile and IV-2, 3 variants are SLBM)

--- SRBM & MRBM

4. Hyunmoo IIC, IV-1, and GrandSlam

Summary

- Hyunmoo IIC, similar to Pershing II, has longer range than its predecessor with M10 speed. 

- Hyunmoo IV estimated at 15t MTOW has various operation specification for Bunker-Busting regarded as important mission in ROK. I assumed that 2nd stage of Hyunmoo IV is the 1st stage of IIC w/ newly updated 2X size of 1st stage of IIC. 

- 8t Bunkerbuster is totally out-classing other Hyunmoo series in its weight. If it has two-stage, it reaches limit of that style. This could deliver 8t warhead for short range as bunker-busting while 1.0t standard warhead fly up to 6000km. More range probably requires three-stage. I assumed that 2nd stage of 8t-Bunkerbuster is 1st stage of Hyunmoo IV considering its short-time development time phase.
