Accelerating U.S. and allied defense spending, supported by substantial increases in procurement and RDT&E budgets (for example, a 22% increase in U.S. spending for FY26) and significant new funding for key Northrop Grumman programs (B-21, Sentinel, and E-2D), is expected to drive sustained revenue growth and provide multi-year order visibility.
