North Korea asked for SU-35 Russian fighter jets

North Korea made an attempt to purchase advanced fighter jets from Russia by sending a special envoy, who visited Moscow as a special envoy of North Korean leader in November last year, and asked Russian President Vladimir Putin to provide Sukhoi Su-35 fighter jets,” a military source said.
Little has been disclosed about the discussions.
It is unknown how many jets the North attempted to acquire.
North Korea operates a fleet of aging and obsolete Soviet and Chinese aircraft. The North Korean air force is comprised of Soviet MiG fighters and some early versions of Sukhoi, hardly a match for the warplanes of the South and the U.S. 7th Air Force based in South Korea.
