I guess using propane tanks for submarines is fairly common

Oh neat! I started looking at propane tanks, then switched to air compressor receivers when I found ones rated for 300 psi, knowing propane is generally 100-200 psi. But now I'm finding some propane tanks rated for 600+ psi...sooooo...guess it depends?
