When RN was advised of an impending sale to Canada why would they want to continue to pour money on storage requirements if they were to be sold off, understandable really. What the RCN and RN didn't know was Chretien couldn't make up his mind to fund the purchase and in the interim the subs condition suffered. When the word was given to purchase, the RCN should have been aware of the condition of these boats. Whether the RCN knew or not, the failure to purchase would have meant the end of the RCN's submarine capability. Getting money to fix the Upholders was possible, convincing the politicos to restart a sub acquisition program with new boats would have been hopeless.
