This is in the family of designs contructed around the Ger/CB/1937 drawing and specifications, dating from February 1999. My opinion of the design is that the dimensions are too small, for what I am trying to do with the design, especially since I am trying for a higher speed than the original 28 knots. This is probably a much better ship than anything that the British or Germans were able to complete during World War II. I must admit that they would have added light AA guns and additional equipment:
