The recent Afghan data breach ranks among the most serious operational errors in recent Ministry of Defence history—unprecedented both in scale and consequence.
While it is right that formal inquiries now seek accountability, we must not overlook a more systemic issue this incident has exposed:
A deeply embedded reluctance within the UK government and MOD to confront human error.
In any fast-paced, high-pressure environment, particularly those facing novel and complex challenges, mistakes will inevitably happen. That is not the failure. The failure is in how those mistakes are responded to.
Too often, the instinct across Whitehall and within departments is not to acknowledge error, but to conceal it, deflect blame, or wait for political or media attention to pass. This fear of embarrassment or reputational damage routinely takes precedence over the institutional learning that is so urgently needed.
We’ve seen this pattern before:
-
In defence procurement failures like Nimrod, Ajax, the Queen Elizabeth-class carriers, and the nuclear deterrent replacement programme,
-
And far beyond defence—in public scandals like Horizon (Post Office) and Windrush.
In each of these, early warnings were ignored, whistleblowers were sidelined, and opportunities to learn were lost. The result: delays, ballooning costs, reputational damage—and worst of all, lives disrupted or lost.
The Culture That Must Change
The uncomfortable truth is this:
Our current government systems are still designed to avoid embarrassment—not to absorb, analyse, and learn from failure.
This has to change—and we already have a model to learn from.
A Better Way: The RAF’s “Just Culture”
Within our Armed Forces, particularly the Royal Air Force, a “just culture” has taken root, one that recognises that errors are inevitable in complex environments. What matters is how we respond.
In the RAF:
-
Mistakes are logged and reported without stigma.
-
Personnel are encouraged, not punished for raising concerns.
-
Insight is shared across the organisation to build resilience and institutional agility.
-
Trust and transparency are embedded, not feared.
Failure is not a personal flaw—it’s a moment to learn, adapt, and improve.
This culture of openness and continuous improvement stands in stark contrast to how the Afghan data breach was handled. The breach was serious—but the instinct to hide it, delay response, and evade responsibility made it worse.
What Now?
Yes, formal investigations must now establish exactly what went wrong in the Afghan data breach. But just as important is the need to examine how the breach was handled once discovered—and what that reveals about our institutional reflexes.
Failure will occur again. We see it on the battlefield in Ukraine and in daily decisions made under pressure.
What defines a strong institution is not the absence of mistakes—but the speed and honesty with which it learns from them.
It’s time for the Ministry of Defence and government more broadly to embrace the principle already proven by our Armed Forces:
Own the mistake. Share the insight. Learn quickly. Adapt faster.
