A Strategic Framework For Strengthening Anti Submarine Warfare (Asw) Capabilities In The Indonesian Archipelagic Sea Lane-2 (ASL-2) To Mitigate Underwater Threats And Protect Indonesia’s Maritime Sovereignty
Abstrak
The Indonesian Archipelagic Sea Lane II (ASL-2) is a strategic shipping route connecting the northern region of Indonesia with the Indian Ocean through the Makassar Strait, Flores Sea, and Lombok Strait. This position gives ASL-2 significant importance for national defence, navigational security, and the protection of Indonesia’s maritime sovereignty. The development of submarines and underwater technologies operated by state actors may pose potential threats to national interests. Current conditions indicate that the Indonesian Navy’s Anti-Submarine Warfare (ASW) capability still predominantly relies on Hull Mounted Sonar (HMS), while the use of Towed Array Sonar (TAS) remains limited, an Integrated Underwater Surveillance System (IUSS) has not yet been established, and bathythermograph and hydro-oceanographic data have not been centrally managed. This study aims to analyse the current condition and capability gaps in ASW, identify the internal and external factors affecting its development, and formulate strategies to enhance the Indonesian Navy’s ASW capability in ASL-2. This study applies a descriptive qualitative method with a case study approach. Data are collected through interviews, limited observation, documentation, and literature review involving informants selected purposively based on their positions and competencies. The data are analysed using Reflexive Thematic Analysis assisted by NVivo to develop themes and identify strategic factors. The identified internal and external factors are subsequently analysed using IFAS, EFAS, and SWOT to formulate SO, WO, ST, and WT strategic alternatives. This study is expected to produce Policies, Strategies, and Efforts to enhance the Indonesian Navy’s ASW capability in ASL-2 based on the research findings. The proposed policies, strategies, and efforts are formulated through thematic analysis assisted by NVivo, identification of internal and external factors, preparation of IFAS and EFAS, and SWOT analysis. This analytical process ensures that the resulting strategy is academically accountable and relevant to the operational requirements of the Indonesian Navy.
