And always take into account that CVs constantly repair themselves. If the total of 8k is spread out too much over time, it may not be enough
takes 8,000 lb for carrier and 2,000 for other ships
my guess the CV takes an hour like the other ships (ie. a CV so damaged that it only needs a few .50 to kill will take an hour to repair fully). so it repairs at 8000lb/hour, or 2000lb every 15mins.

Which is how hangers and "stuff on fire" act. Once they stop smoking, they pop within 5 minutes.
