Is North Korea's ICBM Really a Hoax? - The National Interest Online (blog)

The Hwasong-14 missile that arched over North Korea on July 4 was hailed by its leader as an intercontinental ballistic missile (ICBM), “capable of reaching anywhere in the world.” The announcement sparked headlines across the world, prompting frantic diplomatic activity and launching a flood of comment and analysis.This should not be surprising: while most of Kim Jong Un’s missile tests in the last couple of years had only regional implications, the debut of an incipient ICBM has global ones. A nuclear-tipped, global range ICBM in North Korea’s arsenal could change the balance of power not only in East Asia, but the entire world.As a result, the question of what this missile really was, and what it could or couldn’t do, is being fiercely debated between diplomats and analysts. Was it a hoax? Was it a propaganda ploy? Or was it a true ICBM, or at least a precursor to an ICBM? These questions impact directly on the global policies of the major powers – hence the frantic effort to solve the mystery.Let’s examine the three theories aired to date.The View from Moscow: Russia maintains that the July 4 flight involved nothing more than a garden variety medium range missile that reached a modest altitude of 535 km, stayed in the air 14 minutes, and splashed at a distance of 510 km.This data, attributed by the Kremlin to its recently modernized Missile Attack Warning System, stands in sharp contrast to North Korea’s claims that their missile demonstrated ICBM level performance, reaching an altitude of 2802 km, flying for 37 minutes and splashing down at a distance of 955 km.North Korea’s claims are backed by the Japan, the U.S., and South Korea, each with their own long range radars that can detect and track North Korean missiles. It, therefore, stands to reason that their endorsement of North Korea’s claims is more trustworthy.So why did the Russians go on a limb on this issue? Two possibilities: either their Missile Attack Warning System is myopic, or they needed to downplay the July 4 test out of political expediency.The latter is more likely. Trivializing the North Korean achievement provides Russia with an excuse for blocking UN censure of its client while at the same time rebuking that same client for excessive bluster, which rocks the boat of Russia’s power game in East Asia.    Russia maintains that the July 4 flight involved nothing more than a garden variety medium range missilePurely for Show?: Two other theories about the July 4 missile test recognize its achievements but differ on its significance.One school of thought maintains that the test was essentially a propaganda ploy, using a souped up intermediate range Hwasong-12 play acting as a road mobile ICBM. The theory goes on to claim that road mobile liquid propellant ICBMs are an impossibility due to their fragility and the temperature limitation on their fuel. No road-mobile liquid propellant ICBM has ever been fielded, the current road mobile ICBMs of Russia and China are all solid propellant (neither the U.S. nor any other Western power has ever a deployed road mobile ICBM, liquid or solid).At the core of this claim are the assumed dimensions and weight of the July 4 missile. It is clearly derived from the shorter range HS-12 tested last May, and the newer HS-14 looks like an HS-12 with an added stage and clearly shares the same booster rocket motor as its older sibling.The assumed diameter of the HS-12, which was used as the first stage of the HS-14, is 1.5 meters. This, in addition to the total length of the missile as derived from images of the missile on board its giant 8-axle mobile launcher, provides an approximation of the missile take-off weight through a series of simple ratios between dimensions and weights that are typical to such missiles.The estimated total weight comes to about 25 tons. This is too low for a true ICBM that can “reach anywhere in the world” – in comparison, the Topol M, a true global ICBM, weighs 49 tons. Hence, according to this school of thought, the July 4 HS-14 carried a negligible payload to demonstrate a maximum range of 6000 km – enough to hit Alaska but no further than that.One school of thought maintains that the test was essentially a propaganda ployMoreover, this range cannot be extended by further lightening up of the already lightweight missile and anyway, since the missile is liquid fueled, it could never become a road mobile ICBM. According to this theory, the furor over the July 4 missile has been exaggerated: no major city in the U.S. will ever be threatened by it. The threat from North Korean road mobile nuclear ICBMs will materialize only when they field solid propellant ones, many years in the future.  Time to Panic: In the other corner is the alternative theory that the July 4 test demonstrated a global range ICBM, or its least a precursor, which could deliver a 500 kg payload (enough for a first generation nuclear warhead) to a range of nearly 10,000 km – enough to threaten all major cities on the West Coast and further inland. Proponents of this theory agree that the July 4 missile was an HS-12 with an added second stage, but believe it is much heavier than 25 tons.The key assumption here is that this second stage is a shorter version of the third stage of the earlier HS-13 – the ICBM-like missile first paraded in Pyongyang back in 2012. This makes the first stage (i.e. the HS-12 missile) significantly wider than 1.5 meters, which in turn makes it much heavier than the 25 tons “propaganda missile” theory. With a weight of 40 tons or more, the July 4 missile was a truly global range ICBM. Hence, the time to worry is not many years from now, but right now.
