Abstract

Indonesia stands at a strategic inflection point in maritime defense technology. As the world's largest archipelagic state, custodian of approximately 5.8 million square kilometers of maritime jurisdiction, and a middle power positioned across the geostrategic seam of the Indo-Pacific, the country faces an intensifying convergence of grey-zone coercion, naval modernization races, and technological disruption from autonomous systems. This opinion article argues that Indonesia's prevailing acquisition-led modernization paradigm—dominated by heterogeneous foreign platforms procured under fiscal constraint—is structurally insufficient to deter contemporary maritime threats, particularly persistent incursions in the North Natuna Sea and the broader contest over the South China Sea. Drawing on Mahanian sea power theory, the resource-based view of national defense industries, and emerging frameworks of archipelagic defense, the author contends that maritime defense technology should be reconceptualized not as a portfolio of imported assets but as a sovereign capability stack integrating indigenous design, autonomous and unmanned systems, maritime domain awareness, and interoperable command-and-control. The article evaluates recent milestones—the KSOT-008 autonomous submarine, the Bung Tomo-class modernization under the R41 program, and the indigenous Combat Management System—and argues that without coordinated industrial policy, technology-transfer governance, and human-capital development, these advances risk becoming isolated showcases rather than systemic capability. The piece closes with five policy recommendations for Indonesian defense planners, industry stakeholders, and the broader scholarly community studying maritime security in archipelagic developing economies.

Abstract

The Association of Southeast Asian Nations (ASEAN) is in the midst of a synchronized, asymmetric, and analytically underexamined warship build-up. Between 2024 and 2026, Singapore launched RSS Victory as the first of six Multi-Role Combat Vessels with autonomous-warfare integration, Indonesia commissioned KRI Brawijaya-320 as the largest principal surface combatant in Southeast Asia, the Philippines awarded a contract for new frigate (Full Complement) batches under its Re-Horizon 3 program, Malaysia advanced the long-delayed Maharaja Lela-class frigate program with the launch of KD Raja Muda Nala, and Vietnam, Thailand, and Brunei continued discrete but consequential surface fleet renewal. These trajectories are typically reported as distinct national stories. This opinion article argues that they are best understood as a regional phenomenon with shared strategic logic but divergent industrial and doctrinal implementations. The article advances three claims: (a) the contemporary ASEAN warship build-up reflects a hedging-driven, multi-vector procurement pattern rather than a classical arms race; (b) the dominant industrial signature—East Asian and European shipbuilders supplying heterogeneous platforms across ASEAN—creates a structural fragmentation problem that limits the regional bloc's collective deterrent value; and (c) the strategic future of the surface combatant in ASEAN waters will be determined less by tonnage and firepower than by autonomy, networked integration, and the political-economic sustainability of local industrial bases. The article concludes with five policy recommendations for ASEAN navies, defense ministries, and the regional industrial ecosystem.

Abstract

Maritime defense technology has become a strategic priority as navies, coast guards, and maritime security agencies confront hybrid threats, illegal activities, contested littoral zones, cyber-physical vulnerabilities, and operational complexity of autonomous systems. This systematic literature review synthesizes peer-reviewed research on maritime defense technology, with an emphasis on maritime domain awareness, autonomous and unmanned maritime vehicles, artificial intelligence, satellite surveillance, Automatic Identification System data analytics, undersea systems, and cyber resilience. The review is structured according to the systematic review principles of PRISMA 2020 and evidence-informed management review methods. A Scopus and Web of Science search protocol was proposed using combinations of maritime defense, maritime security, naval technology, autonomous systems, AIS, satellite surveillance, unmanned surface vehicles, unmanned underwater vehicles, cyber security, and artificial intelligence. The synthesis shows that the literature is concentrated around six technological clusters: data-driven maritime domain awareness, AIS-based anomaly detection and prediction, satellite, optical, and synthetic aperture radar surveillance, unmanned surface and underwater vehicles, maritime cyber security, and human-machine cooperation for autonomous maritime operations. The review finds that maritime defense technology is shifting from platform-centric capabilities toward integrated, software-defined, data-intensive, and cyber-resilient systems. However, the literature remains fragmented across engineering, transportation, computer science, safety and defence studies. Major gaps include limited operationally realistic datasets, weak integration between cyber security and autonomy research, insufficient validation in contested environments, and underdeveloped governance models for human-machine teaming. This paper proposes a future research agenda for resilient, explainable, interoperable, and ethically governed maritime defense technology.

Abstract

How does an archipelagic developing economy transition from foreign platform dependency to sovereign maritime defense capability? This study examines the contemporary transformation of Indonesia's maritime defense industrial base through a qualitative multiple-case study of three embedded cases nested within a single organizational and policy context: PT PAL Indonesia (2025) as the anchor of the national naval industrial cluster, the Kapal Selam Otonom (KSOT) autonomous submarine program, and the R41 fleet modernization initiative. Following Yin's (2018) multiple case study methodology and the resource-based view of competitive advantage (Barney, 1991; Wernerfelt, 1984) as the theoretical proposition, this study applies cross-case synthesis to documentary, observational, and triangulated open-source evidence collected between September 2024 and December 2025. Six themes emerged from the cross-case analysis: (a) selective foreign partnership as a strategic capability accelerator rather than a substitute for indigenous development; (b) tacit knowledge accumulation as the binding constraint on sovereign capability; (c) modular and software-defined integration as the locus of strategic value; (d) state ownership and industrial cluster governance as enabling but insufficient conditions; (e) human capital pipelines as the slow-maturing foundation of sustained capability; and (f) doctrinal coherence between platforms and operational concepts as a determinant of capability realization. This study contributes to the defense industrial base scholarship by articulating a context-sensitive model of sovereign capability transition in archipelagic developing economies, complementing dominant frameworks derived from advanced industrial democracies. The implications for Indonesian defense planners, industrial stakeholders, and the broader scholarly community studying middle-power defense industries are discussed.

Abstract

Maritime defense technology has emerged over the past two decades as a strategically consequential but conceptually fragmented research domain, intersecting naval architecture, marine engineering, defense studies, artificial intelligence, cybersecurity, and international security. This article maps the intellectual landscape of the field through a bibliometric analysis of Scopus-indexed publications from January 2000 to December 2025. Following the Scientific Procedures and Rationales for Systematic Literature Reviews (SPAR-4-SLR) protocol, a structured search retrieved 1,847 documents that were screened and refined to a final corpus of 1,213 articles, conference papers, and reviews. Performance analysis was conducted using the Biblioshiny interface of the Bibliometrix R-package, and science mapping (co-authorship, co-occurrence, and bibliographic coupling) was performed in VOSviewer. The results reveal three principal findings. First, annual publication output grew from a baseline of fewer than 20 documents per year in the early 2000s to an estimated 178 documents in 2025, with an inflection point in 2018 corresponding to the convergence of artificial intelligence, autonomous systems, and grey-zone maritime competition. Second, the intellectual structure of the field is organized around five thematic clusters: (a) unmanned and autonomous maritime systems, (b) maritime cybersecurity, (c) naval architecture and combat platforms, (d) maritime domain awareness and surveillance, and (e) defense industrial base and technology transfer. Third, geographic and institutional concentration remains pronounced, with the United States, the People's Republic of China, the United Kingdom, Norway, and South Korea collectively accounting for more than 60% of total publication output, while emerging contributors including India, Türkiye, and Indonesia exhibit accelerating output. The article concludes with implications for scholars, defense planners, and industrial stakeholders, and proposes a research agenda emphasizing comparative case studies in archipelagic states, the integration of AI ethics with autonomous maritime weapons, and the political-economy of defense industrial base development in middle-power navies.

Abstract

Late-industrializing states routinely pursue defence industrial autonomy through procurement-linked technology transfer, yet the resulting capability gains are persistently disappointing. The dominant policy response has been to tighten offset and local content obligations. This article argues that such a response misdiagnoses the constraint. Drawing on absorptive capacity theory, technological capability accumulation, and the economics of military-technology diffusion, it develops the Defence Technology Integrative Capability (DTIC) framework, which specifies defence-industrial capability as the integration of four complementary assets—technoware, humanware, orgaware, and infoware—and argues that their returns are multiplicative rather than additive. The framework's central claim is that capability accumulation is governed by the least-developed asset rather than the average, so that expenditure directed at the wrong margin yields negligible returns. The argument is illustrated with Indonesia, a case selected because it inverts the conventional narrative: SIPRI and World Bank data show Indonesia sustains an expansive defence-industrial programme on a military burden of 0.78 per cent of GDP, gross domestic expenditure on R&D of 0.28 per cent of GDP, and 395 researchers per million inhabitants—roughly one twenty-fourth of the Republic of Korea's research density. No Indonesian firm appears in the SIPRI Top 100. A structured focused comparison with Japan, the Republic of Korea, Türkiye, and India indicates that in each successful case, investment in absorptive infrastructure preceded rather than followed industrial expansion. Seven propositions are derived, an operational measurement instrument is specified, and the implications for offset policies in low-absorptive-capacity economies are drawn. The analysis suggests that offset stringency and local content mandates are weak instruments where the human and organizational base cannot convert transferred knowledge into design capability, and that sequencing—not spending—is the binding policy variable.

Abstract

Indonesia’s defence-industrial policy has long assessed progress through domestic content or Tingkat Komponen Dalam Negeri (TKDN), while naval technological capability remains constrained by licensed assembly. This article argues that TKDN alone misidentifies the foundations of sovereign capability. Drawing on latecomer capability accumulation, complex products and systems theory, global value-chain analysis, and absorptive-capacity theory, it develops the Defence Technology Integrative Capability (DTIC) framework, comprising five interdependent functions: design authority, system integration, technology management, human capital, and industrial ecosystem. The framework positions local content as an outcome of design authority and integration control rather than a precondition. Through comparative analysis of Japan, the Republic of Korea, Türkiye, India, and Indonesia, alongside Indonesian naval lineage analysis (2005–2026), the study finds that capability advances when platforms evolve through derivative designs, as demonstrated by PT PAL’s LPD lineage. It proposes a maturity model, governance architecture, and roadmap for capability-based maritime defence industrialization.
