Few Ballistic Missile Analysis w/ Aerospace-SIM - Part. 5 - Hwasong 12, 15, and 17

Aerodynamics Series

 

 Hwasong series 12~17 are the most powerful and biggest ballistic missiles in North Korea. Precise specification of them are not revealed but this article analyze them as far as possible w/ reasonable guess. Table of contents (b14643.de) that site helps a lot for configurating DB of missiles. Except that Hwasong 15 requires 0.5t warhead to achieve 13000km range, most of speculated DB is well suited.

Summary

- Ballistic trajectory of most recent Hwasong series

- Hwasong-12 is very unique heavy-single stage missile reaching limit of single stage missile. 

- Hwasong-15 is like 70's ICBM now as heavy liquid space rocket, its trajectory is different from others. I think Hwasong-17 is prepared for heavier payload (~1t) for similar range; as a ICBM, more range is un-necesssary. 

- Specification of Hwasong-17 is estimated from scale-law of Hwasong-17; it become weight more than 110t to achieve XX km range w/ 1.0t warhead truly enough as ICBM. 

- However, liquid-fueled rocket is still unstatisfied as military rocket even with TEL, so, next or final phase of N.K will be three-staged solid-fuel rocket which is totally different from Hwasong-series. 

- As a liquid fueled rocket, Hwasong-17 reaches the final milestone, IMO.
