North Korean manned launcher
April 8, 2012
Mr. Jang Myong Jin noted that the DPRK plans to launch a 400 metric tonnes booster in the future
The Iranian satellite carrier Safir-2A is the first version of Safir-2 with the name of Simorgh [Korean name: Unha]. Its length is 26 m, its diameter is around 2.5m and its weight is around 86 tons. Its thrust is around 143 tons. It can put 100 kg satellites into 500 km altitude orbits.
The next step is Safir-3A or Sepehr [unknown Korean name: Puktusong] and Safir-3B or Sarir that can put 1,000 kg satellites into 1,000km altitude orbits. By adding micro thrusters and several side boosters, the Sarir heavy launcher can put payloads into 36,000 km altitude orbits. It is expected to be build during the fifth development program of the country.

New official artistic depiction of a future heavy launcher
Picture from 2009 Arirang Mass Games showing probably for the first time ever an unknown uprated launcher with four strap-on rocket boosters!
Seemingly a future man-rated heavy launcher, as a launch abort escape tower is clearly visible atop the launcher.
The length of the strap-on rocket boosters are less than a third of the total rocket length. Rocket possibly made of 3 stages; alternately made of two stages plus a manned spacecraft with Re-entry Vehicle, Service Module and Orbital Module in shroud.
Videos also show the rear bottom part of the launcher, revealing the exact number of rocket engines in the first stage...
In a nutshell, this new launcher might be very similar in conception and performance with the Chinese CZ-2F.
According to past practice, where ballistic missiles are named after Mars (Hwasong), submarine-launched ballistic missile (SLBM) after Polaris (Pukguksong), launchers after famous mountain (Paektusan) or the Milky Way (Unha), one can speculate that a future heavy launcher could be named after some bright celestial objects like notable constellations, such as Ursa Major. Thus Puktusong (북두성; 北斗星), instead of the obviously unlikely Unha-X. Alternately, Aurora seems to be one of the most popular name among spacefaring powers (Dawn, Shuguang, Fajr, Zarya), therefore Saepyek (새벽; 曙光) would be a well inspired choice, even suitable for any future Korean spacecraft or satellite!

Screen capture from Arirang Mass Games 2013, emphasising new rocket evolutionary path, toward horizontal parallel clustering of strap-on boosters, in opposition with all previous mediatic representations of longilineal rockets, made only of vertically stacked stages.
Very stylized shorter and thickset 2 stages launcher, with 4 strap-on boosters, thus consistent with previous assessment on a Chinese CZ-2F-type convergent evolution.
A man-rated Safir-1D could be a further development of the Safir-1 class, by increasing its reliability through the addition of redundancy of various critical sub-systems.
A Safir-2D could be based on the Safir-2A first stage core, powered by four 37 tons thrust liquid fuel engines and 4 vernier engines.
An addition of a total of four 37 tons thrust strap-on boosters would double its lift-off thrust.
Each strap-on booster might be powered by a single liquid fuel Shahab-3/Rodong uprated engine of 37-tons thrust.
This launcher could be adapted to support a manned orbital E1 mission, as the Safir-2D, similar to the Chinese Shuguang-1 and CZ-2A, with only a few orbits and a single astronaut.
A Safir-3D could be based on the Safir-3A first stage core, powered by four 80 tons thrust liquid fuel engines and 4 vernier engines.
An addition of a total of four 80 tons thrust strap-on boosters would double its lift-off thrust.
The second stage could be powered by a single modified 80 tons thrust engine and four vernier engines.
The Safir-3D could easily launch the two seaters E2 spacecraft made of two modules, the propulsion module of 2.5 tons and the Reentry module of 2.5 tons, as well as a speculative three seaters E3 spacecraft, augmented with another orbital module, similar to the Shenzhou spacecraft.
The name of the North Korean Safir-3-class LV is currently unknown.http://ipic.su/7ytitW.jpg
Safir-class manned LV family evolution: Safir-1D with sub-orbital E1 spacecraft; speculative manned Safir-2D with orbital E1 spacecraft; speculative manned Safir-3D with orbital E2/E3 spacecrafts, or "Puktusong" (?) North Korean version.
