Anton Lazarovich Baklanov is a scientist who was involved in the Stealth Program. A Jew, he immigrated to the US in the early 70s. Baklanov's research was key in helping the U.S. develop stealth technology.
In 1982, the Center ordered the Jennings to abduct Baklanov in order to bring him back to the USSR. The abduction attempt was not successful. Instead Phillip and Elizabeth kidnapped a Mossad agent, who was later traded for Baklanov.
Baklanov was forcibly brought to Russia to help the USSR develop their own stealth technology. Nina is sent to spy on him but instead comes to befriend him, ultimately sacrificing her own future in an attempt to get word to Jacob that his father was still alive.
