Though Reuters could not determine what a standard failure rate would be for air-launched cruise missiles, two experts interviewed by Reuters said any failure rate of 20% and above would be considered high…

U.S. defense officials told reporters this week that the Pentagon assesses that Russia has launched more than 1,100 missiles of all kinds since the war began. The U.S. officials have so far not said how many of those hit their targets and how many failed to do so.

Citing U.S. intelligence, three U.S. officials said the United States estimated that Russia’s failure rate varied day-to-day, depended on the type of missile being launched, and could sometimes exceed 50%. Two of them said it reached as high as 60%.

One of the officials said the intelligence showed that Russia’s air-launched cruise missiles had a failure rate in the 20% to 60% range, depending on the day.
