They make rockets that get us to the space station.
They make cars too, if you consider a less-reliable Fiat knockoff a car.
To make things clear, Russia makes pretty much everything. Manufacturing actually makes larger share in their economy than it is in US economy as it hasn’t been all outsourced to China. There are Russian-made smartphones and tablets, HDTVs, shoes, shirts, even a cheap plastic crap. There are Russian domestic car and truck brands, Ford , BMW, GM, Toyota and others are building there as well.
It is true that oil and gas contributes the most to government spending because it is taxed the most, but the idea that it is all the Russian economy is a bullcrap.
