• Senators demand accountability for $200 billion private equity investment in US defense.
• Private equity firms have acquired over 1,500 defense contractors.
• Concerns raised over potential insider trading and foreign ownership.
• Record $17.7 billion deployed into defense-related deals by mid-2025.

This trend suggests a potential vulnerability in the defense supply chain, which could be exploited by foreign entities.
