Order volume and requirements in NF-90 and Horizon

Order volume connects national requirements with industrial work shares in the NF-90 and Horizon examples. Britain and the United States are said to have accounted at several points for more than two-thirds of NF-90's proposed ships. British requirements reflected Falklands experience, while the American aims included succeeding the Oliver Hazard Perry class and complementing the incoming Burke fleet. Smaller participants are described as feeling that their requirements received less attention. In Horizon, the comparison is twelve planned British ships against four each for France and Italy, with disputes over the firms doing the work and ownership of patents. These examples underpin the source's distinction between American participation in systems research and participation in the proposed hull program. The explanation concerns order size and different national needs, rather than hostility between partners.
