There are two other points I would add.
At the start of our period, some of the expected delivery dates for ships were clearly unrealistic, for instance, the oceanographic science vessel being delivered for October of 2021 when it hadn't started yet. Clearly, there was a need to make some changes.
The other thought I would add is that we comment on the fact that the schedule for the AOPS, the Arctic and offshore patrol ships, was changed to help close a gap that would have opened up in production between those and the Canadian surface combatant, which would have been very costly in terms of loss of trained personnel and the need to rehire and retrain them.
