Iran has officially launched a two-day military exercise titled “Sustainable Power 1404” in the Gulf of Oman and the northern Indian Ocean, marking its first major drill since the 12-day war in June 2025. The large-scale exercise is being seen as a demonstration of Iran’s missile capabilities, naval power, and electronic warfare readiness at a time of heightened regional tensions.
Key Highlights of “Sustainable Power 1404”
The military drill showcased a wide range of Iranian cruise missiles, including the Nasir and Qadir, which were test-fired against designated sea targets. The Islamic Republic of Iran Navy (IRIN) deployed surface and subsurface warships, air units, and electronic warfare brigades as part of the drill.
Notably, two of Iran’s frontline warships, the IRIS Sabalan and IRIS Ganaveh, played a central role in the exercises. Both vessels successfully launched cruise missiles, hitting moving sea-based targets with precision. This achievement highlighted Iran’s improving maritime strike capabilities and its focus on long-range anti-ship missile development.
First Drill After the June War
The “Sustainable Power 1404” exercise is significant as it is the first major military operation by Iran since the 12-day war in June 2025, which saw widespread clashes in the region. Defense analysts view the timing of the drill as Iran’s attempt to showcase strategic deterrence and reinforce its readiness against potential adversaries in the Persian Gulf and Indian Ocean region.
Focus on Naval and Missile Capabilities
Iran’s military leadership emphasized that the exercises are designed to test joint operational readiness across multiple domains. With the inclusion of surface-to-sea, sea-to-sea, and air-to-sea missile launches, the drill highlighted Iran’s ability to coordinate across naval and aerial platforms.
Additionally, the participation of electronic warfare brigades underscores Iran’s efforts to strengthen its cyber and electronic warfare defenses, which are crucial in modern conflicts where satellite and radar jamming technologies play a major role.
Strategic Importance of the Location
Conducting the drill in the Gulf of Oman and the northern Indian Ocean carries strategic importance. These waters are key maritime routes for global energy shipments, including oil and LNG transport. By showcasing its missile and naval strength in these waters, Iran aims to send a strong message about its ability to secure its territorial waters and influence critical shipping lanes.
Regional and Global Implications
Military observers suggest that “Sustainable Power 1404” is not only a domestic show of strength but also a signal to regional rivals and global powers. The exercise reflects Iran’s intent to maintain maritime dominance, counter threats, and expand its role in Indian Ocean security dynamics.
As tensions in the Middle East and surrounding waters remain volatile, Iran’s focus on missile technology, naval readiness, and electronic warfare highlights its strategy of preparing for hybrid warfare scenarios.
Iran’s “Sustainable Power 1404” missile drill demonstrates its growing confidence in missile and naval capabilities. By deploying advanced cruise missiles like Nasir and Qadir, alongside warships such as IRIS Sabalan and IRIS Ganaveh, Tehran is showcasing its determination to safeguard its maritime interests and project power in the Gulf of Oman and northern Indian Ocean.
This exercise reinforces Iran’s message of strategic resilience and sustainable power, shaping the future of regional security and defense cooperation.
