New Icebreaker

It was recently announced that COSCO will build 11 new 19,000 TEU containerships for $1.5 billion, with expected delivery in 2018 (if I remember correctly). It has also been reported that for the Coast Guard to build a new ice breaker it will take 10 years and cost $1 billion. I understand the hulls of a containership and ice breakers are different, and the ice breaker would need some high tech equipment due to where it operates and the fact that it is a military vessel, but the timelines and costs seem way out of whack. What gives?

There several icebreaker threads here, this is one of the more recent.
