This brings me to my second question, Mr. Whitworth.
The polar icebreaker that you're about to begin building soon will be used to ensure our sovereignty in the Arctic, which is fantastic. In fact, that's why I became a Conservative 10 years ago. However, it won't be used to protect the commercial seaway in the south.
Your company and Irving will start building ships in 2017 or 2018—please forgive me if my dates aren't accurate. Irving will be done by 2040, and you will be done by 2030.
In this period of about 25 years, would you be able to enter into a contract to build six new icebreakers, based on your current capacity?
