The Marine Corps is confronting “significant” obstacles in maintaining its most critical weapons systems, largely due to contractors restricting access to repair data, according to the service’s second-highest-ranking general.

Gen. Bradford Gering, the assistant commandant, detailed these challenges in a recent letter to the Senate Armed Services Committee. The reliance on contractors for equipment upkeep has created bottlenecks that threaten operational readiness.

Gering cited specific cases involving several unnamed weapon systems where data restrictions have hampered the Marines' ability to perform repairs independently. The general did not provide a timeline for resolving these issues or quantify the financial impact.

Without direct access to maintenance information, the Marine Corps faces delays in field repairs and increased costs. This dependency raises broader questions about the Pentagon’s reliance on contractors for sustainment, a concern echoed by lawmakers seeking to strengthen organic repair capabilities.

Some industry advocates argue that proprietary data is essential to protect intellectual property and incentivize innovation. They caution that unfettered access could undermine the competitive edge of defense contractors.
