Since 1 and 2 ships are procured in alternate years and the "1 in a year" ships cost more, the fairest estimate of unit price comes from averaging three ships across two years. Funds are spent on long lead-time items in the year before the main procurement of each ship. DDG-114 and DDG-115 together cost $577.2 million (FY2010) + $2.922 billion (FY2011) = $3.499 billion (p. 20), and DDG-116 cost $48 million (FY2011) + $1.981 billion (FY2012) = $2.029 billion (p. 7), making an average for the three ships of about $1.843 billion.
