Hi again Benson.

This was your original statement.

"The following figures are by memory but not hard to google.
Last 6 collins class subs required 8m tons of very specialised plate for the hulls not normal Q&t with sales restricted because of defense grade therefore extreme margins.
DYOR but check out the financial year bisalloy delivered last time they supplied collins class hull steel.
Now its only talk so far by both abbott and gillard but if they deliver on 12 the simply maths would be 16m tons multiplied by extreme margins.'

All I commented on was that you have mentioned "8m" tons and "16m" tons when a Collins class submarine only weighs all up about 0.0033 m tonnes or 3,300 tonnes.

I have said nothing about any belief if they should be built here or not. By the way the american aircraft carriers weigh about 0.1 m tonnes so you are out by about 3 orders of magnitude.
