Sure there is. Anyone who has served an had to fill out an Equipment Repair Order (ERO) has seen the every day screw or bolt that costs over $150. I was really annoyed by this at my shop and asked S-4 (supply) why this was. What it comes down to is that when military vendors sell a plane, radio, tank, etc to the military they aren't selling one product. They're selling a product list (called an SL-3). Each product on that list must be specified, routinely tested (eg: certain amount each batch), and then manufactured. As time goes on, the screw is used in less things that are in production so the batch sizes for production are reduced, which inflates the overhead test cost. A lot of products have pretty interesting test standards; for instance we had a truck that after every significant change had to be blown up a minimum of four times. The base truck was $400k and then the equipment inside - which was the actual configuration that was being tested - cost millions per vehicle. I think the military could benefit from part standardization and longer lifetimes on component production.

> I think the military could benefit from part standardization and longer lifetimes on component production. Years ago in a history class it was asserted that in WWII, because the US had a greater degree of part standardization (I think they were talking about stuff that could be used across multiple tanks and truck models) than the Germans, the US supply lines for keeping everything running could be more effective. A German vehicle was more likely to be out of commission for want of a part. I'm not sure if that's true, or how difficult part standardization is in complex modern equipment. But when the Russians are possibly harvesting chips from home appliances, and when we're all acutely aware of how tangled global supply chains are, I wonder if there will be a push for greater standardization from a strategic motivation rather than a cost one?

Part standardization isn't just bolts and major assemblies but also things like test stands, jigs, and everything else needed to repair something. Every repair bay needs for example a shop crane. Every division will have X number of shop cranes all their maintenance units. If there's a particular model shop crane that works with every engine for every vehicle in the division that's awesome. They just need X shop cranes. But then they get assigned a new type of truck. Its engine is bigger and better than the old model. Unfortunately the existing shop cranes are too small to handle lifting this new engine. Now the division needs a mix of shop cranes and enough where every motor pool has every shop crane necessary to fix any vehicle that comes in.
