Unlike previous shipbuilding contracts, AMECON was only contractually obliged to meet the navy's set commissioning dates for the ships; all other construction deadlines were to be determined at the shipbuilder's discretion.
I modsætning til tidligere kontrakter var AMECON kun forpligtet til at møde flådernes krav om ibrugtagningsdato, alle andre tidsfrister var helt op til værftet.
