We did not estimate operating and maintenance costs. However, we know that, in general, the less expensive the ship, the lower those costs are. Everything would depend on the type of ship chosen to replace the type 26 by a hybrid model.
We are talking about three type 26 ships and 12 type 31e ships. The operating and maintenance costs of the type 31e would probably be significantly less than those for the type 26, but that remains to be seen. A specific analysis would have to be done.
Estimating the operating costs for a hybrid fleet was not part of our mandate. Generally, when ships cost less to buy they also cost less to operate and maintain. That does not automatically mean that the operating and maintenance costs of a hybrid fleet would be higher.
