I just have to ask..........

How long would Japanese yards be building the Godzilla??


Using the rules, I make it 11 years!!1

Thursday, May 29th 2008, 8:37pm

Easy. They're Japanese yards
[Bragging mode on]
THE BEST YARDS IN THE WORLD
[Bragging mode off]
and they can easily deal with the Godzilla design in a matter of seconds. :)

... the amount of time it takes for them to crumple up the plans and toss it into the waste bin.

A most interesting batch of designs. I'd hate to meet up with any DD you designed!

Are you sure you don't mean the Godzilla design can easily deal with the Japanese yards in a matter of seconds?

That is true as welll and probably the main reason the plans end up in the waste bin and prevent that from happening. :)
