Those things are huge compared to what we had on DLG's. I don't recall the number but they were closer to 15" diameter and about 10' long while the Mark 48 is about 20" in diameter and close to 20' long.
You're probably right.
I trusted the net, googled
for the title, and
just looked for the best
picture Google came up with.
It's from this site, here:
