Using FSU jets and GLONASS-enabled nav systems perhaps?
Oh, the irony.
It’s incredible to watch this shift happening in real time. Up to this February, UKR was basically all legacy Soviet gear, MiG-29, Su-27, SA-10/20/17, T-64s etc.
And now assuming things go well, in 10 years, it looks like they’re going to be fully Westernized. Patriot, HARM, NASAMS, JDAM, M777/HIMARS, and Leopard 2 are already inbound in open source literature, and people are making noises about what particular Western jets they need to end up with, be it F-16, Gripen, or something else.
