  11. Design Project Guidance …to produce a design for a ship or group of ships to protect the ships of the Sea Base while in the operating area and …protection of the airborne assets moving between Sea Base and the objective and …protection of the surface assets moving between Sea Base and the beach

  12. Requirements Overview • Protect the Sea Base • Operate in Deep to Very Shallow Water • Operate at 35 knots • AW, SUW, USW/MIW capable • Reduced Manning implemented • Modular Design

  13. Design Philosophy Conclusions Introduction Manning Requirements & Design Damage Control Combat Systems Electrical Hull Propulsion Modularity
