In October, NATO’s senior military officer, Adm. Rob Bauer, said that the price for one 155mm shell had risen from 2,000 euros ($2,171) at the start of Russia’s full-scale invasion to 8,000 euros ($8,489.60).
Russia’s production costs are also far lower than the West’s, in part because Moscow is sacrificing safety and quality in its effort to build weapons more cheaply, Mr. Salm said. For instance, it costs a Western country $5,000 to $6,000 to make a 155-millimeter artillery round, whereas it costs Russia about $600 to produce a comparable 152-millimeter artillery shell, he said.
Not only that, but also at a fraction of a cost.
