Abstract
The effects of hull length on frigate and destroyer performance, capabilities and relative platform acquisition cost are assessed. Three hull forms are used as the basis for the study. They can be characterised by their relation to existing ships as being short and full, long and slender, and average. A parametric study examines the effects of length, displacement, topside geometry and propulsion system on performance and capabilities. Additionally, design candidates are generated for typical frigate and destroyer design requirements, in order to assess relative platform acquisition cost and performance. Results indicate that platform acquisition cost is not necessarily proportional to either length or displacement. Thus, constraints on length or displacement to minimize platform acquisition cost can be inappropriate. In particular, the long, slender ship is best suited for the typical frigate and destroyer missions considered.
