The information on the graphic from that site says the plane flew in July 1997. The YAK-43 never flew, and a far as Lockheed using any of Yakovlev’s design work, that was mostly a Lockheed attempt to gain access to British Aerospace design knowledge. And Lockheed never shared any information on reducing radar cross section on any aircraft.
Below is the full text of the Flight Global article.
21 June, 1995
Lockheed Martin and Yakovlev are discussing a technology-access agreement whereby the US Company would be able to utilise Yakovlev's work on its ASTOVL designs.
The deal has yet to be cleared by the US Department of Defense (DoD).
Mickey Blackwell, president of Lockheed Martin's aeronautics sector, says that the company cannot gain access to British Aerospace ASTOVL technologies because of the commercial agreement between the UK company and McDonnell Douglas.
Lockheed Martin is in competition with McDonnell Douglas and British Aerospace on the Joint Advanced Strike Technology (JAST) programme. This is aimed at eventually producing both a conventional take-off and landing and an ASTOVL aircraft for the US Air force and US Navy.
Blackwell says that the company has tried to persuade the UK Ministry of Defence, which has a memorandum of understanding with the DoD on JAST, that it should have access to UK industrial information.
