Legacy military maintenance scheduling systems require constant expensive upkeep with no modern alternatives

Government agencies are locked into maintaining decades-old depot maintenance scheduling systems that demand millions in annual sustainment costs just to keep operational. The DoD is paying $6.5M+ annually to a single contractor for maintenance of PDMSS because replacing or modernizing the system is prohibitively complex, risky, and expensive. Current solutions fail because there's no viable path to migrate critical military logistics infrastructure without massive disruption and cost.
