Russia is struggling to fund its new Su-57 fifth-generation fighter jet, and have only ordered 12 of the jets while the US ramps up its sales and production of the F-35 – a direct competitor.

Specifically, the US and India have engaged in some preliminary talks about selling the F-35, when India was initially a key investor in the Su-57 project.

Russia’s Su-57 is still in a theoretical stage with few airframes built and new engines and weapons integration sorely lacking, but the F-35 is ready to sell.
