The M80 Stiletto is the largest U.S. naval vessel built using carbon-fiber composites, advanced composite materials and epoxy building techniques, which yields a very light yet super strong hull. The prototype M80 Stiletto is expected to be in use in less than one year. Ships are expected to cost between $6 and $10 million. Historically, ships have evolved to become narrower and deeper to achieve speed and stability. The M Hull, however, became wider, allowing its
