Former Tank Commander Sues Ministry of Defence Over Alleged “Acoustic Shock” from Ajax Armoured Vehicles
By Drooid · · How we work
Core Event
Jonathan Bevan, a former sergeant in the Household Cavalry, is pursuing a claim of more than £500,000 against the Ministry of Defence (MoD). He alleges that high-frequency alarms inside the Ajax armoured vehicle’s cockpit caused “acoustic shock,” leading to chronic tinnitus and mental-health problems. The case is before the Court of Appeal, heard by Lady Chief Justice Baroness Carr, Lord Justice Popplewell and Lady Justice Whipple, with judgment reserved.
Background & Context
The Ajax programme, a £6.3 billion project to deliver 589 armoured vehicles across six variants, has been described in Parliament as “troubled.” Development delays were linked to concerns about excessive noise and vibration. Payments to the American manufacturers were paused between December 2020 and March 2023, and the first vehicles entered service in late 2023, well after the original 2017 target.
Bevan served in Afghanistan before testing the Ajax fleet from June 2017 to 2021. He was medically discharged in June 2023 after reporting chronic tinnitus and mental-health issues.
Timeline
- June 2017 – 2021: Test-track trials of Ajax vehicles, operating the Bowman headset and monitoring alarms.
- March 2021: First notices “ringing or buzzing” in one ear.
- 2022: Diagnosed with PTSD, attributed to Afghanistan service.
- June 2023: Medically discharged.
- April 2023: Damages claim filed in the High Court, Manchester.
- May 2023: Judge Nigel Bird dismisses the claim, finding no compelling evidence of acoustic shock.
- Late 2023: Court of Appeal hears the appeal; judgment reserved.
Data & Statistics
- Claim amount: > £500,000.
- Fleet size: 589 vehicles.
- Program cost: £6.3 billion.
- Noise exposure: Alarm sounded “every six to seven seconds” in his headset, described as a high-frequency “nuclear biological chemical” alarm.
Official Statements & Responses
- Ministry of Defence: Acknowledges high noise levels in the Ajax cockpit but disputes that the noise caused acoustic shock or Bevan’s tinnitus.
- Ben Wallace (former Defence Secretary): Called the programme “troubled” in a 2023 parliamentary debate.
- Court of Appeal: Panel has reserved judgment.
Conflicting Reports & Gaps
- Cause of injury: Bevan attributes his symptoms to acoustic shock from repeated headset alarms; the MoD points to his PTSD diagnosis from Afghanistan.
- Judicial findings: Judge Bird found no “memorable event” linked to acoustic shock, while Bevan’s barrister, Timothy Meakin, says the ruling contradicts medical guidelines.
- Evidence of noise levels: The MoD admits high noise levels existed but provides no quantitative data linking them to Bevan’s symptoms.
Why It Matters
The appeal could set a precedent for how the MoD handles occupational health risks in new combat vehicles. A finding of breach of duty of care may force design changes and affect future procurement, while a ruling for the MoD could reinforce existing liability thresholds for service-related health claims.
