💸 Taxpayer Alert: 81% Over Budget
The Sentinel (GBSD) program has exceeded its original budget by 81%. At $141B, this represents billions in cost growth that could have funded schools, healthcare, or infrastructure. This is a pattern across Pentagon weapons programs — the military-industrial complex has little incentive to control costs.
