Why It Matters

The Army's XM-30 Mechanized Infantry Combat Vehicle program has delivered first prototypes from both competing contractors, but its Milestone B decision has not been signed and the program is being reevaluated, according to a new Congressional Research Service report. ​

Army leadership reportedly declined in February 2026 to sign the Milestone B documentation, effectively pausing formal program transition and prompting a reevaluation. The Army is requesting $547 million in fiscal 2027 procurement funding for 19 prototype vehicles, while prime contractors have not yet been identified.

The Big Picture

The XM-30 is the Army's effort at replacing the M-2 Bradley, following the cancellations of the Future Combat System and Ground Combat Vehicle programs. The report describes the Bradley as "widely considered to have reached the technological limits of its capacity to accommodate new electronics, armor, and defensive systems."

Of five firms awarded Phase 2 concept design contracts in July 2021, only General Dynamics Land Systems (GDLS) and American Rheinmetall advanced to Phase 3/4 contracts in 2023. GDLS delivered its Wolf prototype on Aug. 21, eleven days before American Rheinmetall delivered its Lynx prototype on Sept. 1. The 1st Cavalry Division at Fort Hood, Texas, is reportedly to be the first unit to receive prototypes this fall, with soldiers conducting assessments through March 2027 at the National Training Center at Fort Irwin, Calif.

With Gen. George's retirement in April and Secretary Driscoll's reported resignation on Aug. 31, the Army is presently without Senate-confirmed senior leadership. The report raises two oversight questions for Congress: whether new Army leadership, once confirmed, might hold different views on the XM-30, and whether the vehicle will have an organic counter-drone capability, which the report says is "not clear."

The Bottom Line

Under the rapid prototyping pathway now reportedly in use, a single-vendor down-selection is expected in late spring or June 2027. The fiscal 2027 budget request of $547 million for 19 prototype vehicles remains a request, and prime contractors have not yet been identified. Until new Senate-confirmed Army leadership is in place, the program's current acquisition approach remains an open question before Congress.
