The second phase comprises three Avante 2200 multirole corvettes, HMS AlMadinah, HMS NEOM and HMS AlUla, following five warships delivered in the first phase. The ship's systems will be outfitted, installed and integrated in Saudi Arabia, followed by acceptance trials on Saudi land and in Saudi waters. The phase two contract includes an integrated logistics support package, crew training and a plan to qualify more than 100 Saudi engineers, alongside localising combat systems integration and maintenance. HAZEM, the first Saudi naval combat management system of its kind, was developed by SAMI and Navantia, and GAMI supported the project through its industrial participation agreement with Navantia (SPA; Ministry of Defense). Navantia says the final ship of the batch is due in 2029 and that the contract represents about four million working hours (Navantia).
