The first 100 Ajax armored vehicles delivered to the British Army have been withdrawn from service and are being stored pending technical upgrades.
The information was confirmed by the Ministry of Defence to Parliament, indicating that the vehicles remain in storage locations in Wales and England until they receive the necessary improvements to meet operational standards.
Most of these vehicles were withdrawn from units throughout 2024, with the last one ceasing operation in October 2025.
The Ajax program, which planned initial deliveries as early as 2017, suffered repeated delays and now expects the completion of all 589 units only by the end of the decade, reflecting the challenges faced in developing the armored vehicle.
Although Ajax was declared to have Initial Operating Capability at the end of 2025, this classification was later revoked following new safety concerns. Authorities acknowledged that previous decisions had been made without all technical data being fully available, and the government began treating the program’s future as a critical issue to maintain or cancel, prioritizing the safety of military personnel.
The main reported issues involve excessive noise and vibrations during use, which caused discomfort for dozens of personnel during training, including symptoms such as nausea, disorientation, and hearing difficulties. The failures also revealed internal problems in risk communication within the Ministry of Defence, resulting in the replacement of the program manager after it was found that safety warnings had not been properly relayed to authorities before the vehicles were released for use.
