First, some background. There are actually two ship building contracts at play, as detailed on the federal government's National Shipbuilding Procurement Strategy page.
One contract, for $25 billion, is for straight-up warships:
• six to eight Arctic/Offshore Patrol ships capable of "conducting armed sea-borne surveillance of Canada's waters, including the Arctic."The second contract, for about $10 billion, is for boats for the Department of Fisheries and Oceans and the Coast Guard. They are:
• Two, or possibly three Joint Support ships.
• Fifteen Surface Combatants, which will replace existing frigates and destroyers.
• An Offshore Oceanographic Science Vessel, which is a replacement for the very old (built 1963) CCGS Hudson, based out of BIO in Dartmouth.
• Three Offshore Fisheries Science Vessels, which will replace four boats now in use for scientific research.
• One Polar Icebreaker.
