Vladimir Putin risks running out of usable tanks, missiles and fighter jets because the components they use are made in Ukraine.
The engines for all Russian helicopters, ships and cruise missiles, as well as a significant proportion of fighter jets and surface-to-air missiles, as well as tank components, are manufactured in Ukrainian factories that no longer sell to Russia.
His troops are said to be barely armed after five weeks of conflict and heavy shelling of Ukrainian cities.
Russia’s deputy defense minister said the country is in “phase two” of the conflict and will withdraw from Kyiv to focus on its power base in the eastern Donbass region.
However, Western politicians dismissed the statement as an attempt by Russian generals to save face after Putin suffered significant battlefield casualties as Putin continued to bombard Mariupol, a southern coastal city that could serve as a landing point to resupply his armies in the region.
The crisis will affect the production of T-72 main battle tanks, one of Russia’s most important armored vehicles, as the systems that fire their projectiles will be manufactured in Izyum, a city in eastern Ukraine that Russia has not conquered.
Open-source intelligence estimates put Russia’s loss of 2,000 tanks and armored vehicles, but the true number is believed to be much higher as the tanks ran out of fuel and were abandoned.
It is understood that Russia will also not be able to stock up on Kh-55 cruise missiles capable of carrying nuclear warheads, as they require imported components. The Kh-55, used by Russia, China and Iran, is based on a Kharkiv-made engine, senior defense sources say.
All Russian missiles launched from helicopters and ships use Ukrainian-made engines.
Sources said Russia’s arms stockpile is now “pretty bad” because it hasn’t been able to capture Ukraine as quickly as experts had expected. General Mark Milley, the chairman of the US joint chiefs of staff, predicted that Kyiv would fall within 72 hours of an invasion.
Lieutenant General Yakov Rezantsev, who was reportedly killed in a Ukrainian attack, reportedly told his troops that Putin’s “special operation” would last a few hours. (© Telegraph Media Group Ltd. 2022)
