I view it as high risk.

Cost estimates are more reliable for ships you've been building for a long time.

If the Navy experiences difficulties in one or more of these areas, the number of ships procured in coming years may fall short of the quantities shown in the Navy's shipbuilding plan, and future force levels may be lower than the Navy projects.

The budget we will get next week will likely represent no material change from the budget we had a year ago in terms of attack submarine procurement.
