According to information published by the SIPRI (Stockholm International Peace Research Institute) arms trade database, in 2020, Algeria has ordered a Chinese-made Pattani or Type 056 class corvette that will be delivered in 2023.
The Patani is a class of corvette/OPV (Offshore Patrol Vessel) built by the China State Shipbuilding Corporation. Two ships of this class are already in service with the Royal Thai Navy that were commissioned in 2005.
In 20115/2016 China has delivered three c-28A frigates to Algeria. The three corvettes are fitted with a mix of Chinese and Western systems. The hull-mounted sonar will be of Chinese origin, but Algeria has selected Thales Smart-S Mk2 3D air and surface surveillance radar and Kelvin Hughes for the navigation radar. In recent years, Algeria has purchased a large amount of military equipment from China including SR-5 Multiple Rocket Launch Systems, armed drones CH-3 and CH-4, SM-4 120mm mortar carrier, and Red Arrow-12 anti-tank missiles.
