The Request

• A conceptual design for a High Speed Assault
  Connector (HSAC) to enhance Joint Expeditionary
  Logistics (JELo) flow from the Sea Base to shore
• Augment or replace existing connector platforms
• Employment requirement
• Cargo 8000LT of vehicles, troops, and gear
• Distance 200nm from the Sea Base to shore
• Time 10 hours
• Sea state 4
• Interface accept cargo and troops at the Sea
  Base and deliver to shore

6
The Design Solution

• A system of 12 HSACs that fill all the previous
  connector requirements
• Each HSAC is multi-mission capable,
  self-sustaining, and
• Can accommodate embarked troops, cargo, and gear
  from FLS and or/CONUS to the Sea Base
• Can transit 2000nm _at_20kts (fully loaded) w/40
  fuel remaining
• Has defensive and offensive combat capabilities
