US assesses up to 60% failure rate for some Russian missiles
The United States assesses that Russia is suffering failure rates as high as 60% for some of the precision-guided missiles it is using to attack Ukraine, three US officials with knowledge of the intelligence told Reuters.
The disclosure could help explain why Russia has failed to achieve what most could consider basic objectives since its invasion a month ago, such as neutralizing Ukraine's air force, despite the apparent strength of its military against Ukraine's much smaller armed forces.
The US officials, who spoke on condition of anonymity due to the sensitivity of the information, did not provide evidence to support the assessment and did not disclose what precisely was driving high Russian missile failure rates.

US officials have warned that Russia's accusations that Ukraine might use chemical weapons are a lie, and also an indication Moscow may resort to their use, given past precedent.
President Joe Biden said on Thursday that if Russia were to use chemical weapons in its invasion of Ukraine, the United States would respond.
"We would respond, we would respond if he uses it. The nature of the response would depend on the nature of the use," Biden said at a news conference in Brussels.
