Is naproxen the same as Vimovo?

Could you clarify for me, are naproxen and Vimovo essentially the same medication, or do they differ in some significant way? I've heard both names mentioned in relation to pain relief, but I'm not entirely sure if they're interchangeable or if there are specific situations where one might be more appropriate than the other. Could you elaborate on the differences, if any, and help me understand when each might be prescribed?
