The latest Air Force One aircraft delivered to the presidential fleet lacks the defensive countermeasures that equipped its predecessor, according to U.S. officials. The omission raises questions about the Boeing contract worth nearly $4 billion for two modified 747-8s, which were expected to match or exceed the survivability features of the current VC-25As.

Security experts warn that the absence of missile-warning sensors, infrared countermeasures, and electronic warfare suites creates a vulnerability during presidential travel to contested regions. The previous generation included systems designed to defeat heat-seeking and radar-guided threats — capabilities considered standard for heads of state operating in hostile airspace.

The White House maintains the aircraft meets all safety requirements, though it has not specified whether the missing systems were removed to cut costs, accelerate delivery, or due to integration challenges. Boeing has not publicly addressed whether the capabilities can be retrofitted or if a contract modification is under discussion.

The gap underscores a broader tension in defense acquisition: balancing schedule pressure against capability completeness. If retrofits are required, the cost and timeline will likely fall on the contractor, potentially eroding margins on a program already delayed by years. For investors, the episode signals execution risk on high-visibility fixed-price development work.
