I think a general topic for icebreakers is a good idea. Until now, icebreaker news and discussion have been scattered in Arctic News, Shipyard News etc.
What use would the USCG have for Aurora Australia which is more an ice-strengthened research and resupply vessel with limited icebreaking capability than an icebreaker?
If the USCG is looking to lease foreign vessels to bridge a capability gap, I would propose icebreakers like the 1993-built Fennica and its 1994-built sister ship Nordica.
