Hegseth and JCS Chairman Caine Testify on FY27 Defense Budget Before Senate Appropriations

The Pentagon's FY27 budget request totals $1.5 trillion, a 42 percent increase over 2026, which Hegseth in his opening statement called "admittedly a historic budget." Acting comptroller Jules Hurst told the subcommittees Iran war costs have reached $29 billion, up roughly $4 billion from his estimate two weeks prior; CBS News reported internal U.S. assessments placed the figure closer to $50 billion. A CBO analysis released Tuesday estimated the Golden Dome missile defense system would cost $1.2 trillion over 20 years, against the administration's $175 billion figure. Both parties challenged Hegseth on the absence of congressional authorization; he cited Article 2 authority, and CBS News reported Senators Collins and Paul have joined Democrats in backing a war powers limitation. Graham raised a CBS News report of Iranian aircraft parked on Pakistani military bases; Caine confirmed seeing it but declined to comment given ongoing peace negotiations.

Analysis
The spread between Tuesday's $29 billion comptroller figure and internal assessments nearing $50 billion, reported across three independent outlets, points to managed disclosure rather than transparent cost accounting. Collins and Paul joining Democrats on war powers, alongside Murkowski's AUMF push, places the authorization fight on multiple simultaneous procedural tracks. Caine's refusal to contest Iranian aircraft at Pakistani bases, citing ongoing negotiations, reads as non-denial: confirmation would collapse Islamabad's neutrality and deepen a ceasefire already described as "on life support." The FY27 NDAA is very likely to pass both chambers by end of 2026, though bipartisan hearing rhetoric has historically been a poor predictor of actual floor constraint on executive war powers.
