USSR Sea Dart equivalent???

The Americans worked on a Fighter Jet/Sea Plane called the Sea Dart by Convair but I'm curious as to whether the Soviet Union were working on an Analogue/Counterpart?

I know the USSR were working on a Large Supersonic Bomber Jet/Seaplane called the Bartini A-57 which never reached the Prototype Stage unlike the Sea Dart which had several Working Testbeds so obviously the USSR had some of the Expertise but I do not know more than that.

I'm not referring to Ekranoplans here though just to Clarify.

Any Info on this Subject?
I'd be interested if you can shed any light re this.
 
Bartini created a plethora of innovative concept drawings and variations, but he seems to have been a drawer and not a maker. On the verge of making an actual experimental model to test his concepts, the program was cancelled due to a preference for missiles.
