The event, overseen by General Fayyad bin Hamed al Ruwaili and Admiral Fahad Bin Abdullah Al-Ghofaily, marks the completion of the Al-Sarawat project, aimed at enhancing the naval capabilities of Saudi Arabia in line with the country's Vision 2030.

HMS UNAYZAH, constructed at Navantia’s shipyard in the Bay of Cádiz, is part of an effort to improve the RSNF's efficiency in multi-combat missions and to safeguard Saudi Arabia's strategic interests.

Vice Admiral Fahad Bin Abdullah Al-Ghofaily, in his remarks, emphasized the corvette's contribution to the Kingdom's defense readiness and the project's role in advancing the localization of defense capabilities—a key goal of Saudi Arabia's defense spending strategy.

The delivery ceremony highlighted the partnership between Navantia and the Saudi Arabian Military Industry (SAMI), demonstrating the technology transfer and localization of production capabilities achieved through the SAMINavantia joint venture. This collaboration aligns with Saudi Arabia's efforts to enhance its defense industry and job creation.

HMS UNAYZAH, based on the AVANTE 2200 design, is 104 meters long and accommodates 102 personnel. Its construction and delivery conclude a project that saw the launch of five units within three years, signifying a significant phase in the partnership between Navantia and the RSNF. The contract also encompasses life cycle support and training services, ensuring the corvettes' operational effectiveness.

The commissioning event was attended by senior officials from both Spain and Saudi Arabia, including representatives from the defense sector and the joint venture partners, underscoring the collaborative efforts behind the project's realization.
