Connector Study Conclusions

Ships in the three families are feasible in the 2010 timeframe.

The HSS Family has the highest confidence level relative to the HSC and HSAC Families.

HSS: FEST, FEFT, FETT, and FEAT are feasible but rely on LM6000 propulsion plant and four shaft configuration that is unproven at this time; FSS is feasible but requires only twin screw due to reduced speed requirement.

HSS Family interface issues are high priority; resolving satisfactory at-sea cargo transfer is critical to success.

HSC: HCMB is feasible and has least risk of HSC alternatives.  FNB requires powerplant development.  HCFB is high risk and only marginally feasible and potentially too large for austere ports.

HSAC: MCSB is feasible using proven technologies.  Both MCMB and FWDB require development of skirt technology and ramp systems.  Shallow draft and beaching requirements for high performance small craft are challenging.
