Which Iranian naval force is undergoing major recapitalization to replace aging surface ships and augment the submarine fleet?

• A. IRGCN
• B. Iranian Army
• C. IRIN
• D. Iranian Space Force

Answer: (C)

This question is about which Iranian naval force handles the traditional blue-water role—operating surface ships and submarines—and is pursuing a major modernization to replace aging ships and grow the submarine fleet. That modernization focus aligns with the Iranian Regular Navy, the branch responsible for conventional maritime forces, including frigates, destroyers, and submarines. It emphasizes upgrading and expanding the fleet to maintain long-range, blue-water capability.

The other options don’t fit as well. The IRGC Navy focuses on coastal defense and small, fast-attack craft and asymmetric capabilities, not the large surface ships and submarines central to major naval modernization. The Iranian Army is the land force, not the navy, and the so-called Space Force is not the naval branch in question.
