Yuri Nosenko said the Soviets didn't know he had any connection with the U-2 flights and apparently Oswald didn't admit to. However, I've also read that they did ask him about the U-2 and supposedly he gave them information they already knew. So who knows?
Mr. KLEIN. Who [Oswald] had been a radar operator and had worked on a base from which U-2 airplanes took off and landed, that he wasn't even interesting enough for the KGB to speak to him, to find out if he knew any of this information?
Mr. NOSENKO. Mr. Klein, I understand your position, but we didn't know that he had any connection with U-2 flights. That is one thing. And if you, Mr. Klein, are basing on what was written by Mr. Epstein in the book, it is a little bit from the air taken ideas. Mr. Epstein even telling that how important for KGB to know about such base that base. We knew it in the fifties when I worked in GRU at the Navy, in 1950, 1951, 1952. We knew every base and in Japan, at this Atsugi base, and we knew what kind of airplanes had been. We didn't know about U-2, no. Sure, it is very interesting, but when Oswald applied, requested to stay in the Soviet Union, we didn't know a word about his knowledge, anything concerning U-2 flights.
Mr. KLEIN. And you didn't ask him if he had any kind of information about that when he wanted to defect, is that correct ?
Mr. NOSENKO. No.
Dear Steve M.,
Putative KGB officer Yuri Nosenko, whom true defector Major Pyotr Deriabin determined in 1965 didn't know such basic KGB-officer things as how to send a cable, how many floors of the U.S. Embassy were dedicated to the CIA (3), and where the cafeteria was at KGB headquarters, was a false-defector-in-place in Geneva in June 1962, sent there by Gribanov's Department 14 in the Second Chief Directorate (today's FSB) to discredit what a recent true defector, Major Anatoliy Golitsyn, was telling James Angleton about possible penetrations of the CIA (can you say Richard Kovich, Bruce Leonard Solie, and Leonard V. McCoy?), and a rogue physical defector to the U.S. in February 1964 whose bona fides in the U.S. the KGB had no choice but to support (through Aleksei Kulak, Igor Kochnov, Boris Orekhov, and Vitaly Yurchenko, et al.) because he was telling the CIA and the FBI what it desperately wanted them to hear -- that the KGB had absolutely nothing to do with "abnormal" former Marine sharpshooter and U-2 radar operator Oswald during the two-and-one-half years he lived in the USSR.
BTW, the HSCA ended deeming Nosenko a liar.
I'm surprised that you, intelligent and well-read young man that you are, would lend Nosenko any credence at all. (Ditto Nechiporenko, if you do.)
Have you read Bagley's 2007 Yale University Press book, Spy Wars: Moles, Mysteries, and Deadly Games, and his 2014 follow-up article, "Ghosts of the Spy Wars"? Both are free to read -- just google "spy wars" and "archive" simultaneously and "ghosts of the spy wars" and "archive" simultaneously.
Regarding the theory that Nosenko was a rogue defector in 1964, I suggest that you read W. Alan Messer's fine paper, "In Pursuit of the Squared Circle: The Nosenko Theories Revisited," which you can read for free under my Substack banner, "How the KGB Zombified the CIA and the KGB."
Enjoy!

PS John M. Newman, author of the 1995/2008 book, "Oswald and the CIA," postulates in his 2022 book,
Uncovering Popov's Mole -- which he dedicated to Bagley, btw -- that mole Solie in the mole-hunting Office of Security, upon hearing from (probable mole, imho) Kisevalter in April 1958 that Popov had told him in West Berlin that he'd recently overheard a drunken GRU colonel brag that the Kremlin had all of the top-secret specifications of the U-2 spy plane, sent (or duped his confidant, protégé, and mole-hunting subordinate, Angleton, into sending) Oswald to Moscow in late 1959 as an ostensible "dangle" in a (unbeknownst to Angleton and Oswald) planned-to-fail hunt for "Popov's U-2 Mole" (Solie) in the wrong part of the CIA -- the Soviet Russia Division -- which mole hunt lasted nine years, tore the SRD apart, and drove Angleton nutty cakes.
