HSC Family Conclusions

FNB is feasible but has moderate development risks.

Requires development in areas of powerplant (turbines and waterjets).

Risk area is design for acceptable hull structural responses.

HCMB is minimal risk concept.

HCMB is basically a conventional design, despite need for triple or quad-screw plant; several alternative propulsion options are attractive.

”Economical” (in context of military Sea Basing) at 25 knots threshold speed.

30-knot speed objective can be met with LM2500 gas turbines , either with electric drive and propellers, or with waterjets.

HCFB is potentially feasible, but presents high development and operational risks in several areas.

Monohull and multihull variants both near 45 knots (but not quite: best so far 43.2 kt at 90%)

Catamaran draft is too high (without cushion-assist).

Monohull variants likely to be considered “too big for Port Austere”.
