A lieutenant has been disciplined after using an Army helicopter to deliver a pizza to his girlfriend.
The incident on 25 January saw the unnamed officer divert from a routine training flight over Stanford, Norfolk, to take the fast food.
The Ministry of Defence refused to name the officer, from 659 Squadron, or divulge how he was punished.
A spokesman said: "The chain of command doesn't condone these sorts of actions. The individuals have been disciplined."
He added: "During a routine low-level training sortie, somebody decided it would be an opportunity to use it for a delivery."
The extra cost caused by the diversion is not known.
The pizza was understood to have been delivered to a female officer cadet at an Army range at Thetford, Norfolk.
The Ministry of Defence spokesman did not confirm what toppings were on the pizza.
