Hanwha Ocean has been named South Korea's preferred bidder for the ₩7.8 trillion (USD 5.1 billion) next-generation destroyer program, edging HD Hyundai Heavy Industries by a 0.58-point margin in an evaluation where the loser actually outscored the winner on technical capability—until a security penalty rewrote the result.
The Defence Acquisition Program Administration (DAPA) notified both shipbuilders of their evaluation scores on Thursday, with Hanwha Ocean posting a composite lead of 0.5867 points. Without the security deduction, HD Hyundai Heavy would have won by 0.6425 points on pure technical merit. The 1.2-point deduction—applied because nine current and former HD Hyundai Heavy employees were convicted between 2022 and 2023 for stealing KDDX conceptual-design documents—proved decisive, flipping the outcome entirely.
The Irony Embedded in the Score Sheet
The theft took place between 2012 and 2015, when those documents belonged to Daewoo Shipbuilding & Marine Engineering (DSME)—the very predecessor that Hanwha Group acquired and rebranded as Hanwha Ocean in 2023. In other words, the rival that stole Hanwha Ocean's original design documents is now penalised on those very convictions, handing the contract back to the firm whose intellectual property was taken. DAPA's security-penalty framework, active for HD Hyundai Heavy Industries through December 2026, made the correction automatic once the final conviction was recorded in December 2023.
A court had already rejected HD Hyundai Heavy's injunction request on June 5, clearing the path for Thursday's notification.
What the KDDX Program Involves
The Korea Destroyer eXperimental (KDDX) program calls for the detailed design and lead-ship construction of six 6,000-ton Aegis-equipped destroyers, with the full fleet scheduled for deployment by 2030. The ships will be built around a domestically developed hull and combat system—a first for Korea at this warship class. The program has been under development since 2011; the move to competitive bidding added roughly two years of delay, pushing basic-design completion to late 2023.
Timeline and Next Steps
DAPA will formally announce the preferred bidder as early as July 2026, with contract signing targeted for late July, after the standard appeal and debriefing window. HD Hyundai Heavy stated it "regrets that we were not selected despite our significant lead in the technical score" and said it plans to request a detailed evaluation debriefing—language legal observers read as a precursor to possible objections or main-suit proceedings.
Broader Strategic Context
The KDDX award is the largest single shipbuilding defence contract in Korea in years and arrives as Korean defence contractors compete aggressively for both domestic and export orders. Hanwha Ocean (042660.KS) completed KDDX's conceptual-design phase under its DSME identity in 2012; winning the detailed-design-and-build contract brings the programme full circle under a single corporate lineage. HD Hyundai Heavy Industries (329180.KS) holds the basic design work already carried out, raising questions about intellectual-property continuity in the transition phase.
Hanwha Ocean and HD Hyundai have separately joined forces on a joint bid for Korea's 29-trillion-won nuclear-attack submarine (K-SSN) project—a pairing forced by the sheer capital scale of that programme. Thursday's outcome will recalibrate competitive dynamics heading into that far larger contest.
