Russia's Defence Minister Sergei Ivanov says he is sure the Air Force will repel any hostile clouds looking to rain on next week's Victory Day parade.
Russian pilots are past masters at seeding clouds to make rain fall away from major state events, and Mr Ivanov says they will repeat the feat for the Red Square party celebrating the 60th anniversary of the Allied victory over Nazi Germany.
The party is due to be attended by more than 50 world statesmen and Mr Ivanov says he will guarantee it will be held under a clear sky.
"Only the Defence Ministry can physically ensure a clear sky," he said in an interview with official daily Rossiskaya Gazeta to be published on Wednesday.
However, Russian meteorologists have suggested his pilots might be up against it, amid predictions of rain for the weekend and most of next week.
