Other tasks of the EUNAVFOR MED IRINI mission include monitoring and collecting information on illegal oil exports from Libya and combating human smuggling and trafficking by collecting information on this subject and transferring it to the law enforcement authorities of individual EU Member States.

During the deployment as part of EUNAVFOR MED IRINI mission, the U-35 submarine served mostly as an effective reconnaissance platform using sonar systems to monitor and surveillance ship movements in the area of responsibility.
The U-35 is one of six Type 212-class submarines operated by the German Navy. It was built by the Howaldswerke shipyard in Kiel, Germany (owned by thyssenkrupp Marine Systems). The submarine was commissioned into service in German Navy in March 2015.
The German leading naval industry company thyssenkrupp Marine Systems will build another two Type 212CD (Common Design) for the German Navy and four of these submarines for the Norwegian Navy. The EUR 5.5 billion contract was signed in July 2021.
