McDonnell Douglas Undifferentiated or Other Model
Dispatch Dispatcher
Aircraft Equipment Problem Less Severe
Flight Crew Diverted; Flight Crew Returned To Departure Airport
Aircraft
Approximately 1 hour and 25 minutes into flight; crew sent ACARS advising that both transponders had failed. Flight was near ZZZZZ intersection.  I contacted Maintenance Control to see if there was any advice they could provide; but there was not. Due to security concerns; I did not want to attempt overfly and if ATC would allow; a return back to ZZZZ would be best option. Crew concurred and flight turned around. I contacted ZZZZ and they approved the aircraft to re-enter airspace with no transponder.[The cause was] transponder failure.
A Dispatcher reported an aircraft had both of their transponders fail enroute.  After discussing with flight crew; they decided to turn around and return to the departure airport.
