Syria conflict: Half of German Tornado jets 'not airworthy'
It comes two days before German MPs are expected to vote in favour of military action against Islamic State (IS) militants in Syria.
Defence Minister has stressed that only six of the operational Tornado jets would be needed for the proposed mission.
Germany decided to join the fight against IS after an appeal by French President Francois Hollande in the wake of the 13 November Paris attacks.
But the readiness of Germany's armed forces has long been the subject of criticism.
"The state of our flying systems remains unsatisfactory," the German army's chief of staff General Volker Wieker was quoted as saying on Wednesday.
The defence ministry report, obtained by German media, blamed the problem on the "lack of availability of various spare parts".
Six Tornado reconnaissance aircraft, a naval frigate and a 1,200-strong force will be sent to Syria under the proposals backed by the German cabinet on Tuesday.
The Bundestag is set to start debating the plans on Wednesday, with a vote expected on Friday.
