Key Information

Hsiung Feng II and Hsiung Feng III Anti-Ship Missile Launchers

National Chung-Shan Institute of Science and Technology (NCSIST; Chinese: 國家中山科學研究院; pinyin: Guójiā Zhōngshān Kēxué Yánjiùyuàn) is a Taiwanese state owned corporation, formerly part of the Ministry of National Defense's Armaments Bureau, which is active in the development, manufacturing, support, and sustainment of various weapons systems and dual use technologies.

NCSIST was established by the Taiwanese government to serve as a military R&D and systems integration center. In 2014 it became an administrative corporation owned by the Government of Taiwan. NCSIST is involved in product development, manufacturing, delivery, total life cycle sustainment and maintenance.[4] NCSIST fulfills a function comparable to the American Defense Advanced Research Projects Agency (DARPA) but they also assume mixed roles in competing for and awarding research and development, integration and manufacturing contracts. Along with the Aerospace Industrial Development Corporation, NCSIST it is considered to be one of the two Taiwanese prime defense contractors.[5] It is one of the 100 largest defense companies in the world.[6]

History

Prior to the establishment of NCSIST, Taiwan had a poorly organized national defense industrial program, but the nation was faced with an increasing military threat from the People's Republic of China and a drawdown in international support and exclusion from international forums. The Republic of China would need to build its own set of hardware, instruments, laboratories, and test sites if it was to secure its independence and security.[7] Preparation for the NCSIST began in 1965, ground was broken on the Shinshin Campus in 1966, and the institute was formally inaugurated in 1969. Early work includes various missile and radar systems, as well as systems integration for ROC military aircraft and ships. The NCSIST was also, and remains, active in military construction.[8] After the United States switched diplomatic recognition from the Republic of China to the People's Republic of China the Institute became even more important as Taiwanese authorities felt they could no longer view the United States as a reliable defense partner.[4]

In the 1970s, the Institute replicated and produced the 9M14 Malyutka wire-guided anti-tank guided missile as the Kun Wu.[9] The ROC had obtained the 9M14 Malyutkas from South Vietnam. Due to the dated design and low priority placed on anti-tank weapons by the armed forces it was not widely adopted.[10] By the mid-1970s the Institute employed about 2,000 professionals.[11]

In the late 1970s the Institute embarked on a project to create a short-range ballistic missile prototype known as the Ching Feng. The project was intended as a pilot project to build the necessary skills needed for a long range missile program. The Ching Feng was a single stage missile which could carry a 450 kg warhead up to 110 km. The type was displayed publicly in 1981 but production was cancelled in 1982 because of significant problems with the solid rocket motor and the guidance system.[10] Overall the type resembled the American MGM-52 Lance. The follow on missile to, to be named Sky Horse, was also abandoned in 1981 under US pressure although interest in the type was revived in the 1990s after the Third Taiwan Strait Crisis.[11]

In the 1980s the Institute worked with Honeywell to design a distributed open architecture combat system to replace the obsolete MK 37 Gun Fire Control System aboard Taiwan's Gearing-class destroyers. This system, called the Modular Combat System (MCS), was the first distributed open architecture combat system in the world and featured easily upgradable COTS components. The system had challenges but did the job and was affordable with the architecture, computer, and software all being developed in Taiwan.[4]

In the 1990s Taiwan was faced with tightening restrictions on arms imports from the international community as well as instability caused by the transition from an authoritarian to a democratic system. The Institute responded to these challenges by widening the scope of its R&D programs and implementing a system of vertical integration.[7] In the late 1990s NCSIST developed a space launch platform based on their ballistic missile technology but this program was put on hold under a combination of US pressure and a promise to subsidize Taiwanese satellite launches using commercial American companies such as SpaceX.[11]

In 2011 NCSIST awarded MiTAC a NT$70 million (US$2.22 million) contract to build one prototype "Radar Vehicle for Field Operation and Air Defense." In 2015 police in Taoyuan took into custody three workers and one manager from MiTAC on charges of forgery of data and fabrication of test results. The tender required the vehicle to be able to advance at 8 km/h up a 40 degree incline, the vehicle MiTAC delivered could only advance at 6 km/h. In addition three NCSIST staff were detained on suspicion of colluding with the MiTAC employees to fabricate the test results, these staff then presented the fabricated results to their superiors for approval. The Taoyuan District Prosecutors' Office began investigating after receiving a tip.[12]

Modern history

In 2014 NCSIST was made an administrative corporation by the government, ending its period of secrecy and opening up the opportunity to partner with foreign corporations and export equipment internationally.[13] The new corporate Board of Directors had their first meeting on April 18, 2014.[8] The transition removed a number of restrictions for employees who were now no longer members of the military.[14]

Due to the end of the US Navy's support of the SM-1 missile system NCSIST has taken over support for the system including production of replacement rocket motors.[4] The same approach was taken for the SM-1's Mark 13 missile launcher.[3]

In 2016 NCSIST was awarded a $16.7m contract to carry out a life extension program for the Republic of China Air Force's stocks of MICA and Magic 2 air-to-air missiles. These two missiles arm the ROCAF's Mirage 2000 fighter aircraft.[15]

In 2017 NCSIST announced the commencement of "Project Vega" (織女星計畫) with the goal of producing an advanced domestic fighter as a successor to the F-CK-1. Development was to be split into two parts, the overall design and the engine production, with production to start in 2027. The engine has been dubbed F125XX and is expected to generate 16,400 lbf (73 kN). In 2021 NCSIST stated that work on both parts of the project had progressed ahead of schedule and would be completed by 2024.[16]

In 2017 NCIST exhibited again at International Defence Exhibition in Abu Dhabi after a twelve-year absence. They exhibited 39 items.[17]

In the mid-2010s NCSIST partnered with AIDC and the Republic of China Air Force (ROCAF) to create an advanced jet trainer based on the F-CK-1. AIDC is the prime contractor on the project with NCSIST taking a supporting role. Originally designated the XT-5 Blue Magpie but ruled out as the T-5 Brave Eagle the aircraft is based on the two-seat version of the F-CK-1 but with non-afterburning engines, greater fuel capacity, more stable wing profile, and the removal of the internal gun. The first of four prototypes, designated A1, was rolled out in September 2019.[18] As of end of 2023 31 Brave Eagle (勇鹰) planes have been developed or evaluated.[19] Total order is 66 planes.[20]

NCSIST is participating in the development of the first domestic Taiwanese AUV.[21] In 2019 NCSIST launched an 80-ton 28m long high speed catamaran research and test vessel named the Glorious Star (光榮之星). Built in Lungteh Shipbuilding's Yilan County shipyard the purpose of the vessel is to shorten the research and development process for naval weapon systems.[22]

In 2019 Taiwanese President Tsai Ing-wen ordered the NCSIST to accelerate mass production of the TK-3 and HF-3 in response to increasing Chinese military power and bellicosity. In addition to stepping up missile production the President also ordered NCSIST leadership to focus building up their talent pool and increase partnerships with academia, industry and government at home and abroad.[23] Mass production of the long-range Yun Feng supersonic cruise missile began in 2019.[24]

In 2019 NCSIST opened Taiwan's first national unmanned aerial vehicle test site in Miaoli County. The test site is managed in partnership by NCSIST, the Miaoli County government, and the Ministry of Transportation and Communications (Taiwan). The site features a 20m runway and is rated for testing UAVs up to 150 kg in weight.[25] They also entered into an agreement with Asustek Computer Inc to collaborate on cloud-based storage, artificial intelligence, and Internet of Things technology.[26]

In November 2019 NCSIST tested a new short range anti-ship missile from the Glorious Star which while weighting significantly less than the Hsiung Feng II is said to have the same range.[27]

In March 2020 NCSIST conducted live fire daytime and nighttime artillery and UAV detection tests which were observed by a People's Liberation Army Navy Hsiang Yang Hung-class survey vessel.[28]

In April 2020 Chang Chung-Cheng (張忠誠) replaced Gao Chung-Hsing (杲中興) as the president of NCSIST. Gao had courted controversy by deliberately misinterpreting The Classified National Security Information Protection Act. Chang Chung-Cheng is a retired major general who served in the Combined Logistics Command as well as the Armaments Bureau.[1]

In July 2020 NCSIST was awarded a NT$4.8 billion (US$163 million) contract to produce 516 sets of secure high frequency radios for the Taiwanese military. The military side of the contract will be handled by the Navy with a deadline for delivery in late 2023.[29]

In 2021 the Taiwanese army ordered 50 drone helicopters from NCSIST for delivery by the first quarter 2022.[30]

In 2021 NCSIST deputy director Leng Chin-hsu told the Taiwanese Parliament that NCSIST had three previously undisclosed long range missiles in development. Defense minister Chiu Kuo-cheng added that work by NCSIST on such weapons had never stopped and remained a priority.[31]

In May 2021 the Taiwanese navy ordered a new series of shore based medium-to-long range maritime surveillance radars from NCSIST.[32]

In August 2021 it was announced that an extended range version of the TC-2 had been ordered by the Air Force with 250-300 ordered from NCSIST at a unit cost of NT$30 million (US$1.07 million).[33]

In September 2021 a delegation of Taiwanese legislators paid a visit to NCSIST after approving a NT$240 billion (US$8.63 billion) special budget for domestic weapons procurement.[34]

In 2022 SIPRI placed NCSIST on the list of the 100 largest arms manufactures in the world, ranking 60th with a 2022 operating income of two billion USD and a projected 2023 operating income of four billion USD.[6]

In June 2025 NCSIST signed a deal with drone software company Auterion to integrate Auterion's software with NCSIST drones and partner company drones.[35][36][37] The deal potentially covers millions of drones.[38]

In July 2025 China placed NCSIST on an export control list however NCSIST is already required to avoid sourcing components from China by Taiwanese government regulations.[39][40]

At the 2025 Taipei Aerospace & Defense Technology Exhibition NCIST announced partnership deals with six foreign defense companies.[41] This included jointly manufacturing missiles with Anduril Industries[42] working on air and missile defense integration with Northrop Grumman,[43] work with AeroVironment, Inc on autonomous systems,[44] and joint production with Kratos Defense of a multipurpose drone.[45]

WMDs

[edit]

The institute developed nuclear weapons during the Cold War. In 1967, a nuclear weapons program began under the auspices of the Institute of Nuclear Energy Research (INER) of CSIST. After the International Atomic Energy Agency found evidence of the ROC's efforts to produce weapons-grade plutonium, Taipei agreed in September 1976 under U.S. pressure to dismantle its nuclear weapons program. Though the nuclear reactor was soon shut down and the plutonium mostly returned to the U.S., a secret program was revealed when Colonel Chang Hsien-yi, deputy director of nuclear research at INER, defected to the U.S. in December 1987 and produced a cache of incriminating documents. At present there is no claim that any nuclear weapons program is being pursued.[46]

History

Establishment and Early Development (1969–1980s)

The National Chung-Shan Institute of Science and Technology (NCSIST) was founded in 1969 by the Republic of China government as a specialized entity tasked with advancing indigenous defense technologies to address security imperatives and lessen dependence on imported weaponry. Operating initially under the Combined Logistics Command within the Ministry of National Defense, the institute emerged from strategic preparations dating to 1965, including and groundwork in Taoyuan's Longtan by 1966, to centralize efforts in a secure inland location amid persistent threats from the . In its early phase, NCSIST emphasized foundational capabilities through reverse-engineering of foreign systems and integration of imported components into domestic platforms, drawing initial personnel from Taiwanese academic institutions and expatriate engineers to staff nascent laboratories. Key undertakings included development of technologies and basic munitions production, which served as building blocks for self-sustained military sustainment during the era's geopolitical strains, including U.S. arms supply uncertainties. These efforts prioritized practical, incremental advancements over speculative innovation, reflecting resource constraints and the imperative for rapid operational relevance against cross-strait contingencies. By the , NCSIST had solidified its role as Taiwan's primary defense R&D hub, with operations increasingly consolidated at Taoyuan facilities to enhance efficiency and secrecy, while expanding involvement in systems-level projects like early surface-to-air integrations. This period marked a transition from embryonic setup to structured growth, enabling the institute to contribute tangibly to national armaments without yet venturing into large-scale indigenous weaponry.

Expansion and Key Projects (1990s–2000s)

During the 1990s, the Chung-Shan Institute of Science and Technology (CSIST, predecessor to NCSIST) expanded its focus on indigenous missile systems in response to escalating military threats from the , particularly following the 1995–1996 Taiwan Strait Crisis, which demonstrated Taiwan's vulnerabilities to ballistic missile barrages and prompted greater emphasis on self-reliant defense capabilities. This period saw increased R&D efforts in anti-ship and air defense technologies, building on earlier foundations to achieve operational deployments and advanced testing milestones. By the late 1990s, CSIST had established multiple fixed sites for the Tien Kung I and II surface-to-air missile systems, with the Tien Kung II achieving initial deployment in 1998 after development initiated in the late 1980s. Key advancements included the progression of the , with the supersonic undergoing its first test firing in 1997, marking a shift toward high-speed, ramjet-powered weapons capable of countering modern naval threats. This built upon the subsonic , which had entered naval service in 1990 following development starting in 1983, with improvements like the Block II variant completing qualification by 2007. Concurrently, CSIST initiated the program around 2001, aiming to develop a subsonic, land-attack with extended range for striking inland targets, conducting initial test firings by 2004–2005. The air-launched project also began circa 2000, enhancing precision strike options for Taiwan's air force. In the early , CSIST began integrating partnerships by licensing local manufacturers to produce non-sensitive components, fostering industrial capacity while maintaining core R&D control. However, these efforts faced constraints from U.S. pressures, including concerns over Taiwan's offensive developments and a late-1990s halt to a space launch vehicle program derived from technology, reflecting Washington's restrictions under the . Internal funding limitations and hurdles from abroad further challenged progress, yet empirical testing successes validated the shift toward asymmetric capabilities amid persistent cross-strait tensions.

Recent Advancements and Indigenous Focus (2010s–Present)

Amid escalating cross-strait tensions in the 2010s, the National Chung-Shan Institute of Science and Technology (NCSIST) intensified its indigenous development efforts, aligning with Taiwan's Overall Defense Concept (ODC), which prioritizes asymmetric capabilities such as precision-guided munitions, unmanned systems, and mobile defenses to impose high costs on potential invaders without relying on symmetric force parity. NCSIST's missile production accelerated post-2018, achieving national stockpiling targets two years ahead of schedule by 2024 through facility expansions dedicated to ballistic, cruise, and anti-ship variants, including ramped-up output of Wan Jian cruise missiles for naval and air integration. By late 2024, NCSIST had manufactured over 1,000 missiles, doubling prior yields and supporting the ODC's emphasis on saturating threats with indigenous, proliferated systems. This scaling addressed disruptions from and export controls, fostering greater in high-volume production. In unmanned technologies, NCSIST advanced asymmetric naval and aerial options, including the 2025 unveiling of the high-speed attack UAV in collaboration with Kratos Defense, featuring Mach 0.8 propulsion derived from adaptations for , , or strikes. Complementing this, the Kuai Chi (Fast Chi) attack drone boat, designed for swarm operations with integrated UAV payloads, progressed to evaluations in June 2025, enhancing littoral denial capabilities. These developments, entering phases by mid-decade, underscore NCSIST's pivot toward affordable, scalable unmanned assets to counter numerical superiorities in a potential conflict scenario. Further bolstering air defenses, the enhanced Tien Kung III system initiated in September 2025, providing extended-range interception against ballistic threats. These indigenous advancements, driven by empirical assessments of vulnerability to blockades and invasions, have positioned NCSIST as central to Taiwan's deterrence posture, with outputs tied directly to ODC implementation for resilient, distributed warfare. The National Chung-Shan Institute of Science and Technology (NCSIST), formerly known as the Chung-Shan Institute of Science and Technology (CSIST), played a central role in Taiwan's nuclear weapons research during the 1960s and 1970s. Established in 1969 under military control, CSIST directed efforts to develop nuclear capabilities, including theoretical design calculations for a first-generation nuclear device conducted using its computer facilities between 1974 and 1975. These activities were prioritized following China's nuclear test, which heightened Taiwan's perceived existential threats from the (PRC), prompting a shift toward indigenous deterrence options absent reliable external guarantees. By the late 1970s, CSIST's work advanced Taiwan toward a potential breakout capacity, with the program structured to produce weapons-grade or within months if activated, though publicly framed as civilian under the Institute for Nuclear Energy Research. Persistent U.S. intelligence assessments in the identified CSIST's ongoing contributions to nuclear R&D, including implosion device simulations and materials testing, but no operational weapons were produced. The program was dismantled in following intense U.S. pressure, including threats to withhold arms sales and economic aid, with agreeing to IAEA safeguards, facility inspections, and the return of sensitive equipment. This curtailment aligned with broader nonproliferation commitments, though declassified documents indicate retained latent knowledge and infrastructure that could theoretically enable reconstitution under severe threat escalation. Post-dismantlement, NCSIST redirected resources to conventional systems, reflecting empirical constraints from U.S. oversight and the absence of with the PRC. Allegations of CSIST involvement in chemical weapons research during the 1980s and early center on precursor development from industries and potential integration with delivery platforms, but official denials persist and no verified stockpiles have been documented. 's Ministry of National Defense rejected claims of an active chemical program in December 1998, emphasizing compliance with international norms despite non-party status to the due to diplomatic isolation. U.S. reports from the noted possible biological research facilities with dual-use potential, yet inspections and intelligence yielded no evidence of weaponized agents or production-scale efforts. By 2001, issued unilateral nonproliferation pledges, including facility verifications, marking a verified shift away from such programs amid heightened global scrutiny and strategic pivot to precision conventional munitions. These historical pursuits, while unconsummated at scale, stemmed from causal deterrence imperatives against PRC numerical superiority, with dismantlement evidencing responsiveness to leverage rather than inherent aggression.

Developed Defense Systems

Missile and Rocket Systems

The National Chung-Shan Institute of Science and Technology (NCSIST) has developed the Hsiung Feng series of as a cornerstone of Taiwan's capabilities. The , a supersonic powered by a solid-fueled booster and liquid-fueled engine, achieves speeds exceeding Mach 2 with a baseline range of 120-150 kilometers. An extended-range variant, unveiled in July 2025, extends this to approximately 400 kilometers, enabling strikes against distant naval threats. These integrate with (ROCN) frigates and corvettes, as well as air-launched variants adapted for the indigenous F-CK-1 Ching-kuo fighter in a project initiated in 2022. NCSIST's Tien Kung (Sky Bow) surface-to-air missile family provides layered air and missile defense. The Tien Kung I offers interception ranges from 5 to 80 kilometers against aircraft and early cruise missiles, while subsequent variants like Tien Kung III incorporate anti-ballistic capabilities for short-range threats. In September 2025, an enhanced Tien Kung III variant, dubbed Strong Bow, entered mass production, designed to counter high-altitude cruise missiles and ballistic threats with improved guidance and propulsion. Ground-based batteries support integration with Taiwan's air force radar networks for nationwide coverage. For land-attack roles, NCSIST produced the , achieving ranges up to 1,200 kilometers to target mainland infrastructure. The (redesignated Ching Tien), a supersonic land-attack , extends this to 1,200-2,000 kilometers using propulsion at speeds around Mach 3. Recent efforts include hypersonic variants under development since the early 2020s, with ranges exceeding 2,000 kilometers and technology for Mach 6 speeds, aimed at penetrating advanced air defenses. NCSIST's includes the multiple launch rocket system, a wheeled platform firing guided rockets up to 45-70 kilometers for coastal suppression. Production of these systems ramped up ahead of schedule in 2024, with Taiwan's missile programs overall meeting expanded quotas two years early through NCSIST-led facilities. These developments, tested in simulations against amphibious invasions, underpin Taiwan's asymmetric strategy without reliance on unverified combat outcomes.

Aircraft and Unmanned Systems

NCSIST collaborates with the on the T-5 Brave Eagle advanced jet trainer, contributing advanced avionics including an active electronically scanned array radar to enhance pilot training and light combat capabilities. The program, initiated under a 2017 contract, aims for performance suitable for replacing aging AT-3 trainers, with production accelerating in 2025 to address fleet readiness amid regional tensions. The institute develops unmanned aerial vehicles emphasizing , autonomy, and survivability for , reducing reliance on manned platforms vulnerable to superior adversary air forces. Key programs include the Teng Yun medium-altitude long-endurance UAV, designed for , , , and precision strikes with a range exceeding 1,000 km, 24-hour , and service ceiling of 25,000 feet.

Strategic Role and Impact

Contributions to Taiwan's Asymmetric Defense

The National Chung-Shan Institute of Science and Technology (NCSIST) has played a pivotal role in advancing Taiwan's "porcupine" strategy, which emphasizes asymmetric capabilities to impose high costs on a numerically superior adversary, particularly in denying amphibious invasions across the . By developing indigenous, affordable, and mass-producible systems such as and unmanned aerial vehicles, NCSIST enables Taiwan to focus on and layered defense rather than symmetric force-on-force engagements. This approach counters (PRC) advantages in manpower and platforms through proliferation of low-cost, high-impact weapons that complicate invasion logistics and increase operational risks for aggressors. NCSIST's production achievements have reduced Taiwan's dependence on foreign arms imports, particularly from the , by meeting ambitious output targets ahead of schedule. In 2024, NCSIST produced over 1,000 units, surpassing the goal two years early through expanded and dedicated lines, thereby bolstering stockpiles for sustained deterrence without delays from external supply chains. These indigenous efforts have allowed to prioritize domestic capabilities, with systems like supersonic anti-ship missiles positioned to replace or supplement U.S. variants, enhancing self-reliance amid geopolitical uncertainties. Deployments and tests of NCSIST-developed systems have contributed to empirical deterrence by demonstrating credible capabilities that factor into PRC military calculus. Successful live-fire exercises and fielding of mobile launchers underscore the operational readiness of these assets, fostering a defensive posture that raises the threshold for or . In recognition of these advancements, NCSIST ranked 50th globally among arms-producing entities in 2022 per the (SIPRI), reflecting significant revenue growth and technological maturation that underpin Taiwan's elevated defense posture.
