NPR has some photos of the launching of Russia’s as yet uncompleted, 568 foot long nuclear powered icebreaker. which will be the largest and most powerful icebreaker in the world. The NPR story provided a link to a Sputniknews story.
According to sputniknews.com,
“The Project 22220 vessel is 189.5 yards long (568.5 ft–Chuck) and 37.1 yards wide (111.3 ft). The ship displaces 33,540 metric tons.”
That is almost three times as large as the Polar Star.
A second ship of the class is also expected to be completed before 2020.
Interestingly, while Russian navy projects are frequently subject to delays, this icebreaker is being launched more than a year earlier than originally planned.
Thanks to David for bringing this to my attention.
