Submarine as Spaceship!

Why Not use SUBMARINE as space ship?

A high pressure vessel is not what's needed, since the differential between
a vacuum and 14 psi air pressure is minuscule compared to the near crush
depths travelled.
A nuclear submarine's drive is a steam turbine linked to a screw. In space,
a sub reactor's drive screw is useless.
To launch the useless weight of a submarine into high earth orbit is
counterproductive.

Check out Burt Rutan's Spaceship One and see how much it doesn't resemble a
submarine.

Would the thick hull of a sub not be useful as radiation
shielding...?

The mode of propulsion *would* have to be severely modified. But
if you take out all those useless nuclear-missile bays, that frees up
a lot of space for propellant. Heated by the reactor, it's a simple
NERVA-type reaction drive.

Check out Burt Rutan's Spaceship One and see how much it doesn't resemble a
submarine.

But SS1 is a LAUNCH vehicle. A modified submarine would be used
more as an interplanetary-transit type of vehicle.


You're right about it being counterproductive to launch all that
mass into orbit in one shot, though... better to have the
mining/refining/construction facilities in orbit, and manufacture the
ship there. :-)

Yea, but if you found a water planet, you'd be ready!

Reminds ME of an old Japanese cartoon - Space Cruiser Yamato. Same
idea - mount a reactionless drive on an old sub and take off... :-)

No, not a sub, it's a battleship, a senkan. The real Yamato was sunken
during World War II. In the TV series (an attempt to create the
Japanese version of Star Trek), the surface of the world ocean has
dried in many places (I think that it was due to an alien attack?). Of
course since the ocean surface has dried in many places, the sunken
Yamato was revealed.

After that, the old Yamato was revived and then was revised into a
space capable battleship, equipped with many modern features for space
battles.

The Japanese propaganda is very obviously, "Yamato" is the name that
is often associated with old Japan and the Yamato is one of Japan's
famous battleship.

Whoops... my mistake. (It's been a while since I last saw that
series...)

(shrug) Europa, anyone?

Europa! Crunchy on the outside, chewy in the middle.
