 Ukraine used Atigens missiles against Russia for the first time. Some weeks ago, the US government confirmed that long-range precision artillery, the Army tactical missile system, or Atigens, would be making its way to Ukraine's armed forces. Reports are now coming in of what appears to be a significant Ukrainian strike deep into occupied territory. The US secretly provided Ukraine with long-range Atigens missiles, according to two US officials, providing Ukraine with a significant new capability that could allow its forces to hit new Russian targets that were previously out of reach. US officials indicated to CNN that Ukraine has already used the Atigens, some variants of which have a maximum range of approximately 186 miles, to attack Russia's Berdiansk and Luhansk airfields in eastern Ukraine. The Ukrainian military tweeted that the attack destroyed several Russian helicopters, an ammunition depot and an air defense launcher, but did not specify whether they used Atigens to do it. According to the Wall Street Journal Ukraine Fist-Times used these missiles. Russian military bloggers are gloomily reporting that one of the most serious blows of all time has been dealt to the country's air force. If the strike and the use of Atigens is confirmed, it will be a major development. It is not clear when the US missiles were provided, but the US decided in recent weeks to send them quietly because they wanted to take the Russians by surprise.
