Pukguksong-1
The Pukguksong-1 (Korean: 북극성-1; lit. 'Polaris 1'), also known as KN-11 in intelligence communities outside North Korea, is a North Korean two-stage solid-fueled submarine-launched ballistic missile (SLBM) that had a complete, successful test on 24 August 2016.
North Korea has never announced the actual operational range and payload, as this technical information is probably considered classified.
In 2015, the missile was first launched with a liquid-fueled engine. Later, North Korea replaced the liquid-fueled engine with a solid-fueled one for later test fires.
According to German analyst Norbert Brügge, the earlier launches, conducted from a barge, did not feature grid fins, while the later submarine launched missiles did. The difference between the Pukguksong-1 and the Pukguksong-3 are the missile diameter, with the -1 being about 1.1 metres (3.6 ft) in diameter, while the -3 is about 1.4 metres (4.6 ft), like the Pukguksong-2, an older model Pukguksong-3 also exist, with a similar pointed nose cone.
The missile's range is estimated to be 500–2,500 km (310–1,550 mi).
The Pukguksong-1 is claimed to have two variants: one is the land-based road-mobile medium-range ballistic missile Pukguksong-2, and the other, according to Norbert Brügge, is an SLBM first tested in 2021, later identified as Hwasong-11S.
The Hwasong-11A (KN-23), which is usually reported as an Iskander clone likely uses a Pukguksong-1 solid fuel motor with a different nozzle. Compared to the Iskander, it is noticeably wider and larger; it likely has the same 1.1 metres (3.6 ft) diameter as the Pukguksong-1 and thus shares the engine. Similarly, while the Hwasong-11B (KN-24) is similar to the MGM-140 ATACMS, it is much larger than it with a 1.1 metres (3.6 ft) diameter; it is thus likely to be similar to the Pukguksong-1, but having only one stage.
The motors, at around 1.1 metres (3.6 ft) in diameter, used in these missiles likely derive from the solid fuel motors of the Soviet RT-15, possibly originally acquired for scrap. The casing is made of an unknown metal and the nozzle is likely made from carbon fibre composites, which have been displayed on television.
