Ever wonder how the subs compare to each other in the size department?

I have always wondered and did a few quick missions that show it. I have done three different versions. First, there is the playable subs from a Balao's perspective. Then, there is the playable subs from the Type IXD2 perspective. Lastly, all the subs are included and viewed from the Balao's perspective. Thought the S-Class were small? Not until you see the Midget sub next to them! They look like leviathans!

When you open the mission the subs go in this order:
S-18
S-42
Porpoise
Salmon
Sargo
Tambor
Gar
Gato
Balao
Type IXD2
Type XVIII
In the comparison with all the subs the Midget is next to the S-18 and the Sen Toku is between the Balao and Type IXD2. The Sen Toku is so fat it scrapes against the other subs. I was going to fix it, but I thought it was funny.
