Sustainable Power 1404

Iran conducted its first major naval exercise since the June 2025 conflict with Israel. The two-day drill, named Sustainable Power 1404, took place in the Gulf of Oman and the northern Indian Ocean. It involved missile launches from warships targeting sea-based objectives. This exercise marks Iran’s efforts to restore its military image and assert maritime strength after recent confrontations.
Context of the Exercise
The drill followed a 12-day war in June 2025 between Iran and Israel. During that conflict, Israel struck Iranian air defences and nuclear sites. Iran retaliated with missile attacks on Israeli cities and attempted strikes on a US base in Qatar. The exercise serves as a message of resilience and deterrence amid ongoing regional tensions.
Objectives of Sustainable Power 1404
Iran’s navy aimed to improve combat readiness and enhance command coordination. The drill also sought to reinforce deterrence capabilities by demonstrating missile precision and warship coordination. Officials framed the exercise as proof of Iran’s ability to recover quickly from recent military setbacks.
Components and Deployment
The operation included surface and subsurface warships, air units, missile defence systems, and electronic warfare brigades. Notably, the frigate IRIS Sabalan and the vessel IRIS Ganaveh launched Nasir and Qadir cruise missiles at sea targets. These missiles underline Iran’s long-range strike capabilities and precision targeting.
Geopolitical Implications
The drill is seen as a strategic response to Israeli military exercises simulating attacks on Iranian nuclear facilities. It reflects Tehran’s intent to project power and readiness to retaliate. The exercise also signals Iran’s commitment to maintaining influence in the Gulf of Oman and the Indian Ocean, key maritime corridors.
Military Readiness
By conducting large-scale drills, Iran aims to boost morale within its armed forces and deter further aggression. The involvement of multiple naval and air units indicates a shift towards integrated warfare capabilities. This exercise may influence regional security dynamics, prompting neighbouring states to reassess naval preparedness.
