Construction and career
The Algerian government signed a contract with ThyssenKrupp Marine Systems (TKMS) in March 2012 for two MEKO A-200AN frigates, with option for two additional frigates. The contract also included six AgustaWestland Super Lynx 300 helicopters for the frigates, as well as training and support packages.

As TKMS no longer owns its surface vessels shipyard, the construction of the two frigates was subcontracted to ADM Kiel GmbH shipyard (later owned by German Naval Yards Holdings) in Kiel, Germany. Erradii was launched on 5 December 2014. The ship went on its first sea trial in July 2015. Erradii was transferred to the Algerian National Navy on 23 February 2016 at the shipyard in Kiel. The frigate was delivered to Oran in April 2016. Erradii was inspected and formally commissioned by the Chief of Staff of the People's National Army Lieutenant General Ahmed Gaid Salah on 21 April in Algiers.

Erradii along with FRENCH FRIGATE Guépratte participated in "Raïs Hamidou 2021", an annual joint-exercise between Algerian and French navies, held in Toulon, Algiers and the Mediterranean Sea in September 2021.
