This slide show RCS
as a function of material selection and target angle at 0.3 Gigahertz.

We compared the RCS
for an all steel ship with that of a ship made of composite material.
|
|
|
|
The side-by-side
results show a 20dBsm reduction in the median RCS, if we chose to build a
ship of composite material rather than a totally steel ship.
|
|
|
|
However, due to cost
and structural constraints, we decided to use a
|
|
steel hull –
composite superstructure design for the Sea TENTACLE platform.
|
|
|
|
Further RCS analysis
would have proved beneficial in optimizing this design tradeoff.
