at least a third of the time the Pentagon has a choice of exactly one contractor for any given contract, causing quality and timeliness to suffer and driving up prices.
In a number of cases, in spite of its industrial and financial might, the Pentagon has encountered insoluble problems. Specifically, it turns out that the US has only one shipyard left that is capable of building nuclear aircraft carriers (at all, that is; the USS Gerald Ford is not exactly a success). That is Northrop Grumman Newport News Shipbuilding in Newport, Virginia. In theory, it could work on three ships in parallel, but two of the slips are permanently occupied by existing aircraft carriers that require maintenance. This is not a unique case: the number of shipyards capable of building nuclear submarines, destroyers and other types of vessels is also exactly one. Thus, in case of a protracted conflict with a serious adversary in which a significant portion of the US Navy has been sunk, ships will be impossible to replace within any reasonable amount of time.
The situation is somewhat better with regard to aircraft manufacturing. The plants that exist can produce 40 planes a month and could produce 130 a month if pressed. On the other hand, the situation with tanks and artillery is absolutely dismal. According to this report, the US has completely lost the competency for building the new generation of tanks. It is no longer even a question of missing plant and equipment; in the US, a second generation of engineers who have never designed a tank is currently going into retirement. Their replacements have no one to learn from and only know about modern tanks from movies and video games. As far as artillery, there is just one remaining production line in the US that can produce barrels larger than 40mm; it is fully booked up and would be unable to ramp up production in case of war. The contractor is unwilling to expand production without the Pentagon guaranteeing at least 45% utilization, since that would be unprofitable.
The situation is similar for the entire list of areas; it is better for dual-use technologies that can be sourced from civilian companies and significantly worse for highly specialized ones. Unit cost for every type of military equipment goes up year after year while the volumes being acquired continuously trend lower—sometimes all the way to zero. Over the past 15 years the US hasn’t acquired a single new tank. They keep modernizing the old ones, but at a rate that’s no higher than 100 a year.
Because of all these tendencies and trends, the defense industry continues to lose not only qualified personnel but also the very ability to perform the work. INDPOL experts estimate that the deficit in machine tools has reached 27%. Over the past quarter-century the US has stopped manufacturing a wide variety of manufacturing equipment. Only half of these tools can be imported from allies or friendly nations; for the rest, there is just one source: China. They analyzed the supply chains for 600 of the most important types of weapons and found that a third of them have breaks in them while another third have completely broken down. In the Pentagon’s five-tier subcontractor pyramid, component manufacturers are almost always relegated to the bottommost tier, and the notices they issue when they terminate production or shut down completely tend to drown in the Pentagon’s bureaucratic swamp.
The end result of all this is that theoretically the Pentagon is still capable of doing small production runs of weapons to compensate for ongoing losses in localized, low-intensity conflicts during a general time of peace, but even today this is at the extreme end of its capabilities. In case of a serious conflict with any well-armed nation, all it will be able to rely on is the existing stockpile of ordnance and spare parts, which will be quickly depleted.
