Before opening the next design, the available research branches are checked for anything that could alter the ship. Further rangefinder work will not change the immediate design, whereas special machinery and shells may do so. Research priority then moves to torpedoes. Within the campaign, a technological advance has the greatest procurement value when it arrives before a class is fixed and ordered.

Sequencing research before the next ship design
A technology review favors machinery, shells, and torpedoes that can alter the next design while deferring rangefinder work that offers no immediate change.
