Korea spreads a $1.4 billion missile award across roughly twelve years of development

Hanwha Aerospace and the Hyundai Rotem-LIG consortium are bidding for $1.4 billion, according to the Seoul Economic Daily ^[22], against a schedule that starts full development this year and fields the missile in the late 2030s ^[6][2]. The report does not separate development spending from production. Twelve or thirteen years of that $1.4 billion is $100 million to $117 million a year ^[25].

The push behind it is political. The project gained momentum last December, when President Lee Jae-myung asked, at a briefing by the Ministry of National Defense, the Military Manpower Administration and the Defense Acquisition Program Administration, why the country had developed a fighter jet without developing a domestic air-to-air missile ^[5].

Both bids rest on the same engine. A solid-fuel ducted ramjet draws in outside air during flight to burn fuel, which sustains thrust over long distances and leaves energy in the missile late in flight when a target maneuvers sharply to evade ^[11]. Both bidders claim about the same two decades of heritage in it ^[23]. Hanwha cites more than 20 years of research into that propulsion under the direction of the Agency for Defense Development, plus a record of manufacturing propellants and gas generators ^[9]. Hyundai Rotem and LIG date their ramjet and hypersonic engine work to 2005, and point to long-range air-to-surface and short-range air-to-air missiles they have developed ^[10].

The outcome is expected to hinge on completing the missile as a single integrated system, and on how effectively propulsion, seeker and guidance are brought together ^[12]. An official at Hanwha Aerospace said the company has strengths in integrating surface-to-surface, surface-to-air, air-to-surface and air-to-air missile systems as well as in propulsion development ^[13]. LIG's official listed the Korean GPS Guided Bomb, the Cheonryong long-range air-to-surface missile and short-range air-to-air guided missiles ^[14]. Hyundai Rotem's official said the company is building its own infrastructure at a propulsion test facility in Seosan, South Chungcheong Province, where it can test the performance, design and manufacturing processes of ducted ramjet engines ^[15].

Each bid comes with a case before the courts. Hanwha faces an investigation for violating the Serious Accidents Punishment Act over an explosion at its Daejeon plant ^[17]. An executive at LIG Defense & Aerospace has been indicted and detained on charges of giving money to an official at the acquisition agency ^[18]. The agency's evaluation criteria require assessing risks related to participating companies' serious industrial accidents and integrity ^[21].

Exports are where the spending could come back. Aviation Week reported on Sept. 1 that South Korea's localization effort coincides with a global race in long-range air combat weapons, and that bundling the KF-21 with a domestic long-range air-to-air missile as a single package could strengthen export competitiveness ^[16]. There are no export volumes. Without them, this is a sovereignty purchase at $100 million to $117 million a year ^[25], and MBDA keeps supplying the KF-21's long-range round throughout ^[1]. At that annual number, I would expect Seoul to keep paying. The case weakens if fielding slips well past the late 2030s ^[2], or if the agency splits the scope across both bids and neither firm carries the integration ^[12].
