Both sides have an incentive to over-engineer. The arms manufacturer wants to add as many systems as possible because more complexity = more money. The navy as a whole might want to save money, but the parts that make it up want to spend as much money as possible; if they don't, their budget will get cut since they don't "need" the resources allocated to them. What people sometimes forget about crude Russian engineering is that bubblegum and toothpicks are enough to get the thing operational. Simplicity was always the Russian priority because even in the Soviet days they were broke, and even if they had the money to buy parts getting them to a frozen or muddy air(literal)field in the middle of the middle of nowhere was a feat in itself. The US military-industrial complex has functionally unlimited resources, so the things they build require unlimited resources to operate and function.
