Could Norwegian Type 26 orders change Type 83's design?

Could the additional Type 26s for Norway delay construction of Type 83?

Probably not, because Type 83 was already scheduled much further ahead. The order could instead strengthen the case for a design beyond an enlarged Type 26.

The Norwegian order is judged unlikely to delay Type 83 because that destroyer was already expected to be ordered much later. Type 26 production would still need to accelerate. A more interesting possibility is that the elapsed time could weaken the case for basing Type 83 on an enlarged Type 26 hull. The earlier idea is described as a Type 26 Max, with doubts about whether that hull would remain suitable when the later project advances.
