The Spanish Navy's first new S-80 Plus-class diesel-electric submarine (SSK) has been commissioned into service following the completion of sea acceptance trials.

First-of-class Isaac Peral (S-81) was formally commissioned during a ceremony held at the Spanish Navy's naval base in Cartagena on 30 November.

Isaac Peral is the first of four S-80 Plus-class submarines being built by state-owned shipyard Navantia at its facilities in Cartegena for the Spanish Navy under a contract awarded in 2004. Laid down in 2007 and launched in May 2021 following multiple delays, the lead submarine was put to sea for the first time in May 2022. In early 2023 it moved into final sea acceptance testing, completing its first static dive on 30 March 2023 and its maximum operating depth dive test in October.

Damen Shipyards Group has been awarded a contract for the design, construction, and outfitting of a new multi-purpose vessel for the Portuguese Navy.

Announcing the contract award on 24 November, Damen said the 107 m-long vessel had been designed to meet the Portuguese Navy's requirement for a platform that combined oceanic research with unmanned systems deployment capabilities.

The new vessel, which will be named D João II, is planned to enter service in the second half of 2026.

The project follows a European tender process and has received funding from the European Union's (EU's) Recovery and Resilience Plan (PRR), which is part of NextGenerationEU, the economic recovery package to support EU member states affected by the Covid-19 pandemic. PRR funding for the project is valued at EUR94.5 million (USD103.8 million), with state investment amounting to EUR37.5 million.

The multi-purpose vessel will be used primarily for oceanic research, search-and-rescue, and emergency relief, with a secondary role for naval support and maritime security operations.

The Northern Fleet of the Islamic Republic of Iran Navy (IRIN) officially received its new frigate on 27 November, nearly six years after its previous one sank in an accident.

IRINS Deylaman (78) was formally inducted into service in Bandar-e Anzali on the Caspian, with photographs showing the event took place at one of the port's grain terminals, not at the IRIN base where it was built.

Deylaman replaces Damavand (77), the second of Iran's locally built Jamaran-class frigates, which sank after hitting the breakwater around Bandar-e Anzali during a storm in January 2018.

Satellite imagery shows the first section of the hull for a replacement had appeared in the dry dock at the base by October 2018. Until recently, IRIN officers referred to the new ship as Damavand, and it had the number 77 painted on top of its bridge and helicopter flight deck until October, when this was changed to 78, indicating it was recently renamed after a town close to Bandar-e Anzali.
