Official Description

The Department of War (DoW) is pivotally shifting toward "affordable mass" to counter peer adversaries who are rapidly expanding their military capabilities. While hypersonic systems offer high speeds, their exorbitant costs—exceeding $50 million per round—limit the military's ability to achieve the "magazine depth" necessary for prolonged conflict. This project proposes a ground-based, non-hypersonic, long-range precision payload delivery system that leverages low-cost production methods and co...

Ground-Based Affordable Mass (G-BAM)

# Key Changes to Phase II Requirements **Cost Requirements - Significantly Tightened:** - **Previous:** Flyaway cost <$2 million - **Updated:** All-up flyaway cost <$250K at scale; cost-per-effect <$500K - This represents a ~8x reduction in allowable unit cost, substantially raising the bar for affordability. **Production Capacity - Dramatically Increased:** - **Previous:** 500 units annually - **Updated:** 100+ units monthly (1,200+ annually minimum), or credible path to that rate - More than doubles the annual production requirement and adds a monthly milestone. **Operational Range - Extended:** - **Previous:** >300 nm threshold - **Updated:** 600+ nm objective - Doubles the required range capability, significantly expanding scope. **New Requirements Added:** - **Payload capacity:** Minimum 35 lbs; preference for >100 lbs (completely new) - **DDIL/EW survivability:** Mission capability in denied/disrupted environments (completely new) - **Reliability:** Demonstrate under
