LONDON (Reuters) - Ukraine's President Volodymyr Zelenskiy said on Thursday several Western countries were ready to provide Kyiv with aircraft to defeat Russia's invasion. 

There was no immediate confirmation of any such offer. But below are some details on the jets that Ukraine wants, and what it might get. 

Ukraine has been asking allies to provide modern fighter jets - dubbed "wings for freedom" in Zelenskiy's speech to British lawmakers this week - to replace its ageing fleet of Soviet MiG and Sukhoi planes.

U.S.-made F-16s are on its wish list because of their destructive power and global availability. It also wants Sweden's Gripen fighters, though it has said it is still discussing what jets allies could supply.

Ukraine has been relying on its existing fleet to attack Russian positions and carry out intercept flights, but its air force believes that newer jets could turn the tide of the war.

Such planes would "close the sky" to Russian attacks, Zelenskiy's adviser, Mykhailo Podolyak, said. They would "help to destroy practically any target" in the sky and on the ground, Ukraine's air force spokesperson said.
