K239 Chunmoo

South Korea struggled to come up with countermeasures in the 1970s when North Korea deployed BM-21 Grad, a new multiple rocket launcher (MRL) brought in from the Soviet Union. At that time, the possibility of fatal casualties increased if towed howitzers, self-propelled howitzers, and multiple rocket launchers deployed by the North Korean military fired at the South Korea. The South Korean military developed the K136 Kooryong in 1978 to counter the threat of North Korean artillery. With the deployment of Kooryong to the South Korean Army since the 1980s, it was temporarily able to maintain a similar balance to North Korea's artillery power.

However, over time, problems such as the discontinuation of the main parts of the aging Kooryong system have been revealed, and as North Korea developed a large-caliber rocket with a further increased range, the military pointed out that Kooryong has a limit to respond in wartime. Later, from 2009 to 2013, it developed a new multiple rocket launcher system with an automated fire control system compatible with the ammunition used in the M270 MLRS, which the South Korean military had previously operated, for replacing the aging Kooryong system. The K239 development program was the first defense development program led by South Korean private defense companies, unlike other defense development programs conducted under the leadership of the Agency for Defense Development (ADD).

The K239 Chunmoo is a self-propelled multiple launch rocket system (MLRS) capable of firing several different guided or unguided artillery rockets.

The K239 is capable of launching K33 131 mm rockets, but not 130 mm rockets (such as the K30, K37 and K38), which are used in the existing K136 Kooryong rocket artillery system. The K239 launcher carries two launch pods that can hold three types of rockets:

The CGR080 239 mm rockets are {{convert|3.96|m|ft|sp=us}} long and GPS-aided INS guided, and the rocket is designed to be equipped with two types of warheads, a high explosive warhead developed as a bunker buster, or a cluster bomb warhead, with hundreds of bomblets, for use against personnel in a wide area. The high explosive warhead bursts on impact for use against personnel and bursts after a delay to destroy bunkers; it was a requirement of the ROK Army for the guided rocket to have a penetrator warhead to be used as a bunker buster solution against the large number of bunkers along the DMZ. A guided rocket containing cluster bombs is capable of extensive artillery fire on a specific area of three times the area of a soccer field.

Two different types of rocket pods can be loaded at once. The rocket pod can launch six 239 mm rockets in 30 seconds and a total of 12 rockets in one minute, and it's possible to reload two rocket pods in seven minutes. The launch vehicle is based on a Doosan DST (now Hanwha Defense) K239L 8×8 truck chassis with an armored cab that protects its 3-man crew from small arms fire and artillery shell splinters as well as providing NBC protection. The vehicle can climb 60% slopes (20 degrees), and is equipped with an Anti-lock Braking System (ABS), Run-flat tires, and a Central Tire Inflation System (CTIS).{{cite web|url=https://www.hanwhacorp.co.kr/common/fileDownload.do?path=/upload/defense/chunmoo/Launcher_ASV.pdf&name=Launcher_ASV.pdf|title=Chunmoo System Operational Concept|publisher=Hanwha Group|date=11 November 2014|archiveurl=https://web.archive.org/web/20230701153553/https://www.hanwhacorp.co.kr/common/fileDownload.do?path=/upload/defense/chunmoo/Launcher_ASV.pdf&name=Launcher_ASV.pdf|archivedate=1 July 2023|accessdate=1 July 2023|author=}}{{cite web|url=http://defensetimes.kr/article/_view.php?&ss%5Bfc%5D=4&bbs_id=DefenceTimes_news&doc_num=1716|title=현무 탄도탄 발사차량|publisher=Defense Times|date=9 August 2019|archiveurl=https://web.archive.org/web/20220925134550/http://defensetimes.kr/article/_view.php?&ss%5Bfc%5D=4&bbs_id=DefenceTimes_news&doc_num=1716|archivedate=25 September 2022|accessdate=25 September 2022|author=}} Each Chunmoo launcher is paired with an K239T Ammunition Support Vehicle (ASV) which uses the same type of truck chassis and carries four reload pods.

Development of the K239 Chunmoo began in 2009 and was completed in late 2013. South Korea's Defense Acquisition Program Administration (DAPA) spent 131.4 billion won ($112.4 million) on the project to create a replacement for the K136 Kooryong MLRS. Initial production was carried out in August 2014. The main purpose of the Chunmoo MLRS is to suppress North Korea's artillery systems in case of war.

• In order to reduce operational and maintenance costs, the Chunmoo launcher system is mounted on the modified chassis of a four-axle Korean truck which has less cross-country ability when compared to tracked vehicles.
• The artillery unit does not have permanently mounted launch rails. This allows the Chunmoo to transport and use launch containers containing different types of rockets from one platform.{{cite web|url=https://www.hanwhaaerospace.co.kr/eng/whatwedo/product/template/popupTemplate.do?seq=101|title=Chunmoo Guided Rocket|publisher=Hanwha Aerospace|date=|archiveurl=https://web.archive.org/web/20230701152354/https://www.hanwhaaerospace.co.kr/eng/whatwedo/product/template/popupTemplate.do?seq=101|archivedate=1 July 2023|accessdate=1 July 2023|author=}}
• The cockpit of the vehicle is armoured to provides protection against small-calibre weapons and artillery shell fragments.
• It is equipped with a load-lifting device, similar to that of the MLRS. The estimated maximum recharging time is 10 minutes.
• The Chunmoo system includes an ammunition transport and charging vehicle on a common 8x8 chassis, and carries two sets of transport and discharge containers.
• The Korean army requested that the Chunmoo be designed to fire different types of ammunition. This includes 227 mm standard MLRS, but also 131 mm and 239 mm South Korean rockets. The maximum range of the 131 mm ammunition is up to {{convert|36|km|mi|sp=us}} and approximately {{convert|80|km|mi|sp=us}} for the 239 mm ammunition.
• Rockets can be fired from the cockpit of the combat vehicle, or by using a remote fire control device.
• Chunmoo system was specified to be transportable by aircraft of the C-130 type, in order to be easily deployed.{{citation needed|date=March 2025}}

In June 2022, South Korean Agency for Defense Development (ADD) revealed efforts to increase the range of the Chunmoo's 239 mm rockets to {{convert|200|km|mi|sp=us}}. This would give them range similar to the North Korean 300 mm KN-09. Research and development efforts are evaluating ducted rocket propulsion technology, which adds an air inlet that absorbs external air and combines it with a gas generator for combustion to produce greater thrust, as well as a valve that controls the flow of gas for maneuvering.{{cite web|url=https://www.bizhankook.com/bk/article/23865|title=[밀덕텔링] [단독] 천무 로켓탄, 북 초대형 방사포 대응 '사거리 3배' 연장 추진|publisher=BizHankook|date=10 June 2022|archiveurl=https://web.archive.org/web/20221014060258/https://www.bizhankook.com/bk/article/23865|archivedate=14 October 2022|accessdate=14 October 2022|author=Kim Min-seok}}{{cite web|url=https://www.defensenews.com/global/asia-pacific/2022/06/24/south-korea-is-trying-to-double-the-range-of-its-k239-rocket-launcher/|title=South Korea is trying to double the range of its K239 rocket launcher|publisher=Defense News|date=24 June 2022|archiveurl=https://archive.today/20221014054015/https://www.defensenews.com/global/asia-pacific/2022/06/24/south-korea-is-trying-to-double-the-range-of-its-k239-rocket-launcher/|archivedate=14 October 2022|accessdate=14 October 2022|author=Daehan Lee}} There is also research into a larger 400 mm rocket based on a miniaturized version of the Ure surface to surface missile, which the Chunmoo could carry four of.

On 27 April 2022, South Korean Defense Acquisition Program Administration announced a plan to develop a vehicle-mounted tactical surface-to-surface guided weapon (Ure-2). The purpose of this development project is to improve the existing Ure-1 to increase the range from {{convert|180|km|mi|sp=us}} to {{convert|290|km|mi|sp=us}} and integrate tactical ballistic missile systems into various types of Transporter Erector Launcher (TEL) such as the K239 Chunmoo. The development project is scheduled to begin in 2023 and plans to complete the development with a total budget of 1.56 trillion won (US$1.232 billion) by 2034.{{cite web|url=https://www.thecommoditiesnews.com/news/articleView.html?idxno=4424|title=차량탑재형 전술지대지유도무기(KTSSM-II) 개발|publisher=CNews|date=27 April 2022|archiveurl=https://web.archive.org/web/20221015015409/https://www.thecommoditiesnews.com/news/articleView.html?idxno=4424|archivedate=15 October 2022|accessdate=15 October 2022|author=Park Tae-jeong}}
