6. Specs
▲ Comparison with the two different Hwasonpho-8 type (left) and Hwasongpho-16-Na type wedge-shaped HGVs.
▲ A skip-glide HGV: That's how the DPRK statement described the HS-16-Na.
Since September 2021, North Korea has flight tested three types of HGVs, namely a conical shaped one and two wedge-shaped. In the 2nd April 2024 test, the wedge-shaped HGV (atop the Hwasongpho-16-Na) did not demonstrate any clear advantage over the conical-shaped one. In comparison, the conical-shaped HGV appears to have been tested under harsher conditions. The conical glider flew in denser atmosphere (40 km lower), and made a more radical "cross-range" move to reach the same 1000 km range (pic 1, 2). Burnout velocity of the 2022 test was probably much higher.
▲ Hypersonic glide vehicles tested by North Korea until April 2024.
• It is a HGV-type hypersonic missile following the Hwasonpho-8 and Hwasonpho-12 .
• Compared to the Hwasonpho-8 , the shape of the warhead is different, and the engine has been changed from a liquid propellant main engine with auxiliary verniers engine configuration to a single solid propellant engine configuration. This is similar to the case of the Korean People's Army Hypersonic Missile Type 2 and the Korean People's Army IRBM to be unveiled in 2024.
• Through comparison with the Hwasonpho-18, it may be a missile that shares the first stage with the Hwasonpho-18. Hwasonpho-18 is a three-stage solid propellant ICBM.
• There are two instances of this where the Soviet Union improved an ICBM and made it an IRBM. An opinion was also added that it could be a shortened form of Hwasonpho-18 in this way.
• The paint is a combination of black and white checkered pattern similar to Hwasonpho-15 and Hwasonpho-17. Therefore, in some say the HGV warhead looks like a smiling killer whale when viewed from the front.
• This is the third Type-Na missile to be released following the Hwasonpho-11-Na and Hwasonpho-12-Na . The problem is that the identity of “Hwasonpho-16” has not yet been revealed.
• The mobile missile launcher is similar to the TEL of Hwasonpho-18, with only the missile canister being slightly different. The number of wheels is 14, which is different from the existing ones.
• The flight speed of Hwasonpho-16-Na is said to be 15 to 18 times the speed of sound.
• Jang Young Gyun, director of the South Korean Missile Center, predicted that the Hwasonpho-16-Na's range would be at least 4'500 km.
• There is an opinion in South Korea that it has a range of 8'000 km, similar to China's Dongfeng-27 HGV ICBM.
7. Forecast
Back in 2017, North Korea has disclosed it was working on scramjet-powered warhead technologies.

If North Korea had made a Hwasong-14 ICBM with triconic nuclear warhead, it would not claim the missile as a "new strategic weapon that the world does not have and can not imitate."
As you can see, the idea is that the Hwasong-14 ICBM is a completely new missile with no equivalent in the world and that can not be imitated.
Like the Russian Topol-M ICBM nosecone, the long, thick conical-shaped Hwasong-14 warhead nosecone is an indication that the nosecone contains a scramjet-powered warhead that alters course midflight.
▲ Russian scramjet engine used to produce a new class of ICBM, for illustration purpose only.
Furthermore the first HGV mockup disclosed in October 2021 also shows an air breathing engine.
▲ First HGV mockup disclosed in October 2021 also shows an air breathing engine, in Pyongyang's Defence Development Exhibition, named Self-Defence 2021.
Following the Hwasonpho-8 HGV, the Hwasonpho-16-Na HGV is therefore only another incremantal step toward this goal. We should expect more tests culminating with the ultimate Hwasonpho-20 scramjet-powered HGV with 15'000 km range solid propellant ICBM.
