Can I exchange bought vehicle?

I bought the Su-39 but its not great for air so is it possible to exchange it for the MiG-23ML?
If so where can I do it?

the Su-39 will be decreasing BR in air rb at some point when they split the battle ratings between air and ground
i don’t think you can exchange the vehicle though.

You cannot refund/exchanged vehicles you’ve used and pack assets you’ve consumed such as premium time or GE.

The SU39 has much better ir missiles than the mig 23 and with 59kg per sec Fire burst the Most in the Game. I Love This Plane

You can refund if little time passed when it comes to pack premium time. 0 battles and no GE spent play deciding role when it comes to refunds. A day or 2 should be fine.
