Defense Spotlight Inside the Arsenal of KDEF: LIG Nex1 Takes Aim
In the high-tech arms race reshaping global security, LIG Nex1 is quietly becoming South Korea’s not-so-secret weapon.
For U.S. financial advisors and investors evaluating the Plus Korea Defense Industry Index ETF (KDEF) understanding LIG Nex1’s footprint across air, sea, unmanned, and electronic warfare domains offers a front-row view of the strategic muscle behind the ETF.
Precision at Every Altitude
If it flies, tracks, or intercepts, LIG Nex1 probably helped build it. The company operates across air defense, naval combat, electronic warfare, command and control and unmanned systems, supplying the technology backbone for South Korea’s rapidly modernizing military. [1]
Among its flagship developments:
- Cheongung II (M-SAM): a medium-range surface-to-air missile system exported to Iraq and the UAE. [2]
- Haegung (K-SAAM): a ship-based anti-air missile core to Korea’s naval defense [3]
- Electronic Warfare Suites that detect, jam, and deceive enemy radar and are installed on Korean Fighter Jets, airplanes, ships, land and unmanned aerial devices [4]
- Unmanned surface and aerial platforms: including a new naval reconnaissance USV (unmanned surface vehicle) under development for the Republic of Korea Navy [5]
LIG Nex1 isn’t just a contractor, it’s an integrator, bringing together precision guidance, radar, surveillance and AI-driven targeting in one ecosystem.
Export Firepower and Global Reach
While Western headlines focus on U.S. and European defense names, Korea’s export machine is accelerating. In 2024, LIG Nex1 landed a ~US $2.8 billion contract to supply Iraq with the Cheongung II surface to air missile system, one of the largest single defense exports in Korean history. [2]
The company also secured deals with Saudi Arabia and the UAE, further boosting South Korea’s rise to the world’s 10th-largest arms exporter, with a 2.2 % share of global trade. [6]
Even more striking, LIG Nex1’s “Poniard” guided rocket passed a U.S. Navy Foreign Comparative Test in 2024, hitting six out of six targets, a milestone that could open future procurement pathways. [7]
To extend its global reach, the company recently established a European office in Munich, designed to support NATO-aligned cooperation and local research and development. [8]
The KDEF Connection
Inside KDEF (as of 10/20/25), LIG Nex1 plays a vital role as a technology-driven anchor holding. It connects Korea’s traditional industrial might with its modern defense tech edge. With deep expertise in radar systems, missile electronics, and communications, LIG is central to the digitization of defense where intelligence, automation, and precision converge. Its ability to land high-value government contracts (domestic and foreign), invest in R&D, and scale exports makes it one of the more visible “engine companies” inside KDEF.
Across South Korea’s defense industry leaders, combined order backlogs now exceed ~US $78 billion which is a strong pipeline that could potentially continue to reinforce KDEF’s earnings exposure as export deliveries ramp through 2026. [10]
Why U.S. Investors Should Monitor
- Bridge to U.S. defense exposure: LIG’s performance offers indirect exposure to rising demand in allied systems and global security dynamics.
- Export upside & growth optionality: successes like Poniard in U.S. tests create optionality for direct entry into U.S. defense procurement paths.
- Diversification within defense tech: many defense ETFs are heavy in legacy platforms (aircraft, armor). LIG provides tech-driven exposure (EW, unmanned, smart munitions).
- Correlated yet differentiating driver: as one of KDEF’s more innovation-oriented firms, LIG’s stock behavior may accentuate upside in periods of technological re-rating.
From radar networks and smart missile systems to unmanned defense platforms, LIG Nex1 represents Korea’s edge in defense innovation. KDEF seeks to offer investors a window into how that edge is reshaping global defense supply chains and investment opportunity.

Emerging markets involve heightened risks related to the same factors as well as increased volatility and lower trading volume. The Fund’s concentration in an industry or sector can increase the impact of, and potential losses associated with, the risks from investing in those industries/sectors.
The Fund’s concentration in a single country or a limited number of countries will increase the impact of, and potential losses associated with, the risks from investing in those countries.
