The Russian air force has lost just one-tenth of its fleet while many of its military capabilities remain largely unaffected after more than two years of war in Ukraine, the top U.S. commander in Europe told Congress on April 10. “Russia’s strategic forces, long-range aviation, cyber capabilities, space capabilities, and capabilities in the electromagnetic spectrum have lost no capacity at all. The air force has lost some aircraft, but only about 10 percent of their fleet,” said Army Gen. Christopher G. Cavoli, the head of U.S. European Command and NATO’s Supreme Allied Commander.
