Sea-based defense diplomacy, soft use of the navy through participation in activities such as student-centered exchange of maritime universities, visits by ships and submarines to littoral state, Communications of vessels at sea for coordination and in the fight against piracy and maritime terrorism, relief and salvation is institutionalized at the seas and oceans. In general, maritime defense diplomacy is a process that leads to increased maritime cooperation between the maritime institutions of the coastal states. From another point of view, maritime defense diplomacy is based on the peaceful use of one country's navy and defense and government institutions to cooperate with another country's navy, defense and government institutions in order to achieve a desirable result. The present study uses a descriptive-analytical method to investigate the role of the strategic navy of the Army of the Islamic Republic of Iran in the development of sea-based defense diplomacy. The findings of this study indicate that in general, the relations between the navy and the maritime industry related to defense affairs at the international level can be in the direction of macro diplomacy of a maritime country to protect and safeguard national interests. From this point of view, sending high-ranking naval delegations to participate in international Symposium such as IONS and the participation of various fleets in the form of shipping security fleets and training fleets of naval university students to international waters and visiting developing and developing maritime countries can have a significant impact on the promotion of sea-based defense diplomacy. Continuation of sea-based defense diplomacy can create a profound change not only in the field of sea-based defense but also in the field of maritime industry development and sustainable maritime development. Therefore, the promotion of sea-based defense diplomacy can play an important role in promoting and protecting national interests. In addition, the visit of naval training, peace and friendship fleet will strengthen public diplomacy, expand maritime relations with the littoral countries of the oceans and seas. Finally, the efficient and effective presence of the Strategic Navy in international waters has enhanced the security of the country's maritime transport lines such as non-oil exports, exports of crude oil and gas condensate, imports of basic goods and basic items of the country.
