[PSUBS-MAILIST] Life boats

Tue Aug 11 01:56:13 EDT 2020

I see. Even a ballast tank system that allows the vessel to submerge less
than 10-20 meters below surface level would suffice for research purposes.
It is mainly to test the effectiveness of various radar absorbing
materials, so there is no need for the vessel to be able to reach great
depths in this case, although if it's possible to engineer such
modifications that would be fantastic. If you do view them in person,
please do inform me as to what they're equipped with. Either way, I would
love to come see them myself in person too whenever that is possible.
