Algorithm is given for development of underwater object outer architecture when design computer tech-nologies are used based on hydrodynamic and hydroacoustic criteria for outline quality evaluation when prototype is not available. Methodology of primary design process of outline shape with choice of the qualifiers is described. Geometrical and mathematical models are developed on the basis of these qualifi-ers. These models assist in calculation of architectural surfaces being initial information in application programs of hydrodynamics and hydroacoustics, the main purpose is to solve variational design problems.
