• Equipped with DP2 positioning and three‑anchor mooring for 90 m depth
• Carries ROV to 900 m and AUV to 300 m depths
• First private Spanish shipyard to build a steel Navy vessel
• Supports Navy Diving School, enhancing underwater infrastructure protection

Pulse Analysis

The launch of Prosperina (A22) signals a milestone for Spain’s maritime defence and industrial base. Built by the historic Freire Shipyard, the 32.9‑meter diver support vessel blends traditional steel construction with modern, eco‑friendly technologies that trim fuel consumption and lower emissions. Its dynamic positioning (DP2) and three‑anchor mooring system provide the stability required for deep‑water operations, while a 500‑nautical‑mile range ensures sustained presence in national waters. By integrating a high‑performance ROV capable of 900‑meter dives and a modular AUV reaching 300 meters, the ship equips the Navy’s Diving School with cutting‑edge tools for training, infrastructure inspection, and rapid response.

Underwater security has become a strategic priority as critical assets—subsea cables, gas pipelines, and power links—lie on the ocean floor. Divers supported by vessels like Prosperina are essential for safeguarding these lifelines against sabotage, natural hazards, and emerging threats. The vessel’s dedicated hyper‑baric chambers, side‑scan sonar, and tactical coordination spaces enable prolonged missions and complex interventions, reinforcing Spain’s ability to protect its maritime domain and contribute to NATO’s collective underwater readiness.

Freire’s achievement as the first private Spanish yard to deliver a steel Navy vessel highlights a broader shift toward domestic procurement and sustainability in defence shipbuilding. The project showcases Spain’s capacity to produce high‑tech auxiliary ships for both national and export markets, positioning the country as a competitive player in the global naval support segment. As navies worldwide seek greener, more versatile platforms, the Prosperina program may serve as a template for future public‑private collaborations that blend heritage craftsmanship with modern environmental standards.
