The missile also carries the US government designation KN-04, along with the competing unofficial Western labels Scud-D and Scud 2^4,8. Those names are not simple synonyms for one well-documented object. They reflect years of analysts trying to reconcile satellite photos, defector reporting, and test debris that did not always point clearly to the same missile⁴.

North Korea built the Hwasong-9 by enlarging the airframe of its earlier Hwasong-6 (the North Korean-built Scud-C), lengthening the fuselage and widening the propellant tanks to trade payload weight for extra range^1,3. It remains a single-stage, liquid-fueled, road-mobile missile fired from a wheeled transporter-erector-launcher rather than a fixed silo, the same basic launch concept used across most of North Korea's Scud-derived missiles.

The earliest reported test date and the missile's identity are genuinely hard to pin down. The CSIS Missile Threat project lists a 1991 development start and a 1993 first flight¹, dates that line up suspiciously well with the well-documented Hwasong-6 program rather than with anything specifically identifiable as the extended-range variant. Independent missile analysts Markus Schiller and Robert Schmucker concluded that a September 2016 test was the first genuine public demonstration of the type, after more than fifteen years of rumor with no confirmed sighting⁵. This article treats the 2016 test as the first solidly confirmed data point for the Hwasong-9 specifically, and flags the earlier 1990s dates as unverified rather than settled fact.

Whatever its exact early history, the missile has since found real users. Syria received the system, or the means to assemble it domestically, around 2000^1,3, and Russia reportedly fired North Korean-supplied Hwasong-9 missiles into Ukraine beginning in late 2023, the first confirmed instance of North Korean ballistic missiles used in combat by a foreign military¹⁰. The plain answer to whether the Hwasong-9 is still in service is yes for North Korea, and it was yes for Syria until the collapse of the Assad government at the end of 2024 upended that country's entire missile force. There is no reliable public unit cost figure for the Hwasong-9, consistent with North Korea's general refusal to publish weapons pricing.

An Enlarged Hwasong-6 Airframe With a Lighter Warhead

The Hwasong-9 grew out of the Hwasong-6, itself the domestically-built version of the Soviet Scud-C. North Korean engineers lengthened the fuselage and enlarged the fuel and oxidizer tanks, trading tank volume and payload weight for reach^1,3. Even so, published figures for the finished missile disagree more than usual for a Scud-family weapon. CSIS Missile Threat lists a length of 13.5 m and a diameter matching the Hwasong-6's 0.88 m¹, while Schiller and Schmucker's technical review of September 2016 test footage measured a shorter 12.8 m airframe that was noticeably over 1 m across, wider than any earlier Scud variant⁵. Launch weight estimates run from about 6,400 kg up to 9,200 kg depending on the source^2,5. None of these gaps are trivial, and no single figure here should be treated as definitively settled.

What most sources agree on is the missile's basic architecture. It is a single-stage, liquid-fueled missile carrying an estimated 500 kg payload^1,2, launched from a wheeled road-mobile transporter-erector-launcher instead of the fixed silo basing used by larger strategic missiles. Guidance is inertial, without the terminal seeker or active homing that would sharpen its accuracy, and CSIS estimates its circular error probable at roughly 3,000 m¹, wide enough that the missile is realistically an area weapon against a city district or airbase rather than a precision strike tool.

A Separable Warhead and a Reentry Vehicle Iran Had Already Shown

The September 2016 test also revealed a warhead section that separates from the missile body after engine burnout, improving reentry stability and reducing the reentry vehicle's radar signature compared with a simple unitary Scud warhead². Analysts noted that the reentry vehicle's shape closely resembled one already displayed years earlier on Iran's Qiam-1 missile, a derivative of the Scud-C-based Shahab-2 that Iran itself built with early North Korean assistance⁶. Whether that resemblance reflects direct North Korea-Iran cooperation or parallel engineering solutions to the same aerodynamic problem remains disputed, but the similarity was striking enough that multiple missile-technical analysts flagged it independently⁶.

North Korean and allied sources describe the Hwasong-9 as capable of carrying a conventional high-explosive warhead, a chemical payload, or in principle a miniaturized nuclear warhead^1,2. Only the conventional role is confirmed by actual combat use. No public source has confirmed a nuclear warhead ever mated to this specific missile type, and treating that capability as more than a theoretical option would overstate what is actually known.

Basing on a Wheeled Launcher, Not a Silo

Like nearly every North Korean missile short of its newest intercontinental designs, the Hwasong-9 fires from a wheeled road-mobile launcher rather than a fixed silo, the same basing logic used by the shorter-ranged Hwasong-6 and the longer-ranged Hwasong-7. Road mobility lets North Korea disperse and hide launchers between mountain tunnels ahead of a launch, complicating any attempt to strike the force on the ground before it fires. The Hwasong-9 is neither cold-launched from a canister nor rail-mobile, unlike some of North Korea's newer solid-fuel systems such as the Pukguksong-2, discussed further in the Comparison section below.

Production totals and the size of North Korea's Hwasong-9 force have never been disclosed, unlike some newer systems where satellite imagery or defector accounts have allowed rough estimates. What is documented is the type's export history, which runs almost entirely through one country, Syria, discussed in History and Operators below.

A Scud-C Upgrade Rumored for Fifteen Years Before Anyone Saw It Fly

Long before North Korea publicly tested the missile most Western analysts call Hwasong-9, intelligence agencies and independent researchers suspected an extended-range Scud existed. Rumors of a longer-flying Scud derivative circulated for more than fifteen years without a single confirmed public sighting⁵. CSIS Missile Threat's own program history, a 1991 development start, a 1993 first flight, and possible 1994 production, is presented as tentative for exactly this reason. That window overlaps almost completely with North Korea's confirmed, better-documented Hwasong-6 program, which began testing around 1990 and reached service by roughly 1992¹. It is entirely possible that 1990s reporting sometimes attributed to an early Scud-ER actually described the Hwasong-6 program, misidentified at a distance. This article does not resolve that dispute and treats any pre-2016 date specific to the Hwasong-9 as unconfirmed.

From launch points inside North Korea, a 700 to 1,000 km range reaches every part of South Korea, most of Japan, and parts of northeastern China and Russia's Far East, which is precisely the geographic logic behind extending the shorter Hwasong-6's reach in the first place^1,2.

The September 2016 Tests That Finally Confirmed the Missile

On September 5, 2016, North Korea launched three ballistic missiles from Hwangju in North Hwanghae Province, all of which flew roughly 1,000 km and landed about 240 km west of Japan's Okushiri Island^2,5. Kim Jong Un personally supervised the launch according to North Korean state media². Schiller and Schmucker's technical review of the launch footage concluded this was the missile type's first genuine public demonstration, identifying a diameter over 1 m, a roughly 12.8 m airframe, and a launch mass around 9.2 metric tons, figures that only became checkable once real launch video existed⁵.

A second round of tests followed on March 6, 2017, when North Korea fired four to five missiles from the Sohae Satellite Launching Station, three of which reportedly landed inside Japan's exclusive economic zone^1,2. Both test series showed a missile with a demonstrated maximum range of about 1,000 km, matching its advertised extended-range role relative to the shorter Hwasong-6.

Four Names for One Missile, Hwasong-9, KN-04, Scud-D, and Scud 2

Open-source trackers have never fully agreed on what to call this missile. North Korean state media itself has increasingly used the native term Hwasongpho for its Hwasong-series missiles since 2017, adding yet another label to the pile³. The US government designation is KN-04. Independent Western analysts have separately used ER-Scud, Scud-D, and Scud 2 for what most now treat as the same weapon⁴. Missile analyst Jeffrey Lewis has called it his least favorite North Korean missile designation for exactly this reason, noting that confirmation the ER-Scud specifically carries the Hwasong-9 name, rather than an earlier attribution to the Hwasong-7, only came after Russian analyst Vladimir Khrustalev's visit to Pyongyang years after the type was first rumored⁴. Even reference sites built specifically to track these designations show the strain. GlobalSecurity.org's own page addressing the Scud-ER is filed at a web address written for the older Hwasong-6/Scud-C, a small but telling sign of how tangled the naming has become even among specialists⁷.

Syria's Licensed Line and the Missile's Export History

Syria is reported to have received the Hwasong-9, or the means to build it domestically, around 2000^1,3. Damascus reportedly converted its own Hwasong-6 production line to build the longer missile instead, and the United Nations documented North Korean assistance with Syrian development of maneuverable launch vehicles for the type from 2008 onward³. That made Syria the missile's only confirmed export customer for most of its service history, until the collapse of the Assad government at the end of 2024 upended the picture entirely, covered further in Operators below.

Syria's 2012-2013 Scud Campaign Against Rebel-Held Territory

Beginning in December 2012, the Syrian government under Bashar al-Assad fired volleys of Scud-family missiles at rebel-held towns and bases, including strikes near Aleppo and Tel Rifat in February 2013 that flattened dozens of houses⁹. Reporting from the period generally distinguished between older Soviet-supplied Scud-B missiles and the newer, North Korean-provenance Scud-C and Scud-D types in the Syrian arsenal, without always specifying which individual missile in a given salvo was which⁹. That leaves open exactly how many of the 2012-2013 strikes involved the Hwasong-9 specifically rather than the shorter-ranged Hwasong-6, a genuine gap in the public record rather than one this article can responsibly close.

The Syrian government's missile force, along with most of its Iranian- and Russian-supplied heavy weapons, was largely destroyed by an intense Israeli air campaign in the weeks after the Assad government collapsed in December 2024^11,12. Israeli officials stated the strikes destroyed the large majority of Syria's strategic weapons stockpiles specifically to keep them out of the hands of the armed factions that took power in Damascus¹¹. Whatever Hwasong-9 missiles remained in Syrian government hands at that point are not confirmed to still exist as a functioning force today.

Russia's Use of North Korean Missiles Against Ukraine

The most recent and best-documented combat use of the Hwasong-9 involves neither North Korea nor Syria. Beginning in the winter of 2023 to 2024, Russia reportedly began firing North Korean-supplied ballistic missiles, including the Hwasong-9, into Ukraine as part of the wider Russo-Ukrainian War, specifically during the full-scale invasion phase that began in February 2022¹⁰. The US Defense Intelligence Agency confirmed North Korean missile use through debris analysis in May 2024, after former US Navy officer Chuck Pfarrer first reported the deployment on social media¹⁰. Exactly which Ukrainian targets these particular missiles struck has not been publicly specified, and Ukrainian officials have said their forces had limited prior experience identifying North Korean missile debris, another honest gap rather than a settled fact¹⁰.

Combined, these two conflicts make the Hwasong-9's real combat record almost entirely a story about proliferation rather than about North Korea's own battlefield use. North Korea itself has never fired the type in anger.

The Syrian-Assembled Version

Syria's variant is the only substantial derivative line reported for the Hwasong-9. Rather than simply importing complete missiles, Damascus reportedly converted its existing Hwasong-6 production infrastructure to build the longer Hwasong-9 airframe domestically, with North Korean technical assistance extending to the missile's maneuverable launch vehicles from 2008 onward³. No separate designation distinguishes Syrian-built missiles from North Korea's own, and no serial-production totals for either country's output have been made public. Following the collapse of Syria's government in December 2024, it is not clear whether this production capability still exists under the country's new leadership.

North Korea, the Type's Only Confirmed Long-Term Operator

North Korea remains the only country with a confirmed, ongoing operational Hwasong-9 force, deployed on wheeled launchers as part of its wider Scud-derived inventory alongside the shorter Hwasong-6 and the longer-ranged Hwasong-7^1,2. Public estimates of how many launchers or missiles North Korea fields have not been disclosed.

Syria, From Confirmed User to Uncertain Future

Syria operated Hwasong-9 missiles, or missiles assembled domestically from the design, from around 2000 until the collapse of the Assad government in December 2024^1,3. Israeli airstrikes in the following weeks destroyed most of the former regime's heavy weapons stockpiles, including its strategic missile and air defense systems, specifically to prevent them falling into the hands of the armed factions that took power in Damascus^11,12. Whether any Hwasong-9 missiles or launchers still exist under Syria's new government is not publicly confirmed, and describing the country as a current operator would overstate what is actually known after that campaign.

Russia, a Wartime User Rather Than a Traditional Buyer

Russia does not fit the traditional operator profile. Rather than a peacetime purchase and long-term fielding, Moscow received and fired North Korean-supplied Hwasong-9 missiles as part of its war against Ukraine beginning in the winter of 2023 to 2024¹⁰, a transactional wartime relationship tied to North Korea's broader military support for the Russian war effort rather than a standing Hwasong-9 force within the Russian military.

Hwasong-9 vs Hwasong-6, the Same Airframe Traded for Reach

Extending the Hwasong-6's range meant giving up payload, not adding a new stage or engine. The Hwasong-6, the base Scud-C-derived missile, flies a shorter few-hundred-kilometer range with a heavier warhead, while the Hwasong-9 trades some of that payload weight for the extra propellant needed to reach roughly 700 to 1,000 km^1,3. That range-for-payload tradeoff, rather than any new engine or stage, is what actually separates the two missiles, and it explains why the Hwasong-9 exists at all instead of North Korea simply building more Hwasong-6s or skipping straight to the Hwasong-7's longer medium-range reach. For a country deciding what to fire at a given target, the practical choice between the Hwasong-9 and Hwasong-6 usually comes down to whether the extra 200 to 500 km of reach is worth a lighter warhead.

Hwasong-9 vs Pukguksong-2, an Old Liquid-Fuel Design Against a New Solid-Fuel One

The starkest contrast within North Korea's medium-range inventory sits between the Hwasong-9's decades-old liquid-fuel Scud architecture and the newer Pukguksong-2's solid-fuel, canisterized, cold-launched design introduced in 2017. Where the Hwasong-9 needs a lengthy liquid-fuel loading process before launch, leaving it exposed on its launcher for longer, the Pukguksong-2 fires from a sealed canister with pre-loaded solid propellant, cutting launch preparation time dramatically. The tradeoff runs the other way in production terms. The Pukguksong-2, built on North Korea's submarine-launched Pukguksong-1 technology, currently arms far fewer North Korean units than the older, cheaper, mass-producible Hwasong-9 and Hwasong-6 do. A choice between fielding more Hwasong-9s or investing further in Pukguksong-2 production is really a choice between numbers today and survivability and readiness tomorrow.

Is the Hwasong-9 still in service

Yes for North Korea, which remains the type's only confirmed long-term operator. Syria operated the missile from around 2000 until the collapse of the Assad government in December 2024, after which Israeli airstrikes destroyed most of the former regime's strategic weapons stockpiles^11,12. Russia began firing North Korean-supplied Hwasong-9 missiles into Ukraine in the winter of 2023 to 2024 as part of its ongoing war, a wartime transfer rather than a standing Russian arsenal¹⁰.

What is the Hwasong-9's range

Multiple sources put its demonstrated maximum range at roughly 1,000 km, with a stated operational range band of 700 to 1,000 km depending on payload weight^1,2. That places it at the boundary between a long-range short-range ballistic missile and a true medium-range ballistic missile, and different trackers classify it differently for exactly that reason.

What warhead does the Hwasong-9 carry

It carries a single warhead of around 500 kg, reportedly available in conventional high-explosive, chemical, and potentially nuclear configurations^1,2. No public source confirms a nuclear warhead has ever actually been mated to this missile type.

How much does the Hwasong-9 cost

There is no reliable public unit cost figure. North Korea does not publish weapons pricing, and no independent estimate specific to the Hwasong-9 has surfaced in open sources.

Is Hwasong-9 the same missile as Scud-ER, KN-04, or Scud-D

Most Western analysts now treat Hwasong-9, Scud-ER, KN-04, Scud-D, and Scud 2 as names for the same missile, though the overlap took years of analysis to confirm and some older reporting may have conflated it with the Hwasong-6 or Hwasong-7^4,7.
