Between Flap Retract and Slat retract; above 3;500 feet MSL we experienced dual FMC failure. Lost all Nav information; Autothrottles; and FMS derived speed information. We informed ATC and requested vectors to OPALE. I think we were still prior to PG092 on the OPALE 2G departure; but not sure since it was not present on the standby flight plan. Asked departure for radar vectors to run checklist. As we were leveling at FL100; we were given a climb to FL140; started the climb then were told to remain at FL 100. I think we climbed to about 10;400 feet before descending back to FL100. Ran QRH checklist and talked to dispatch. Dispatch preferred us to land at EGSS. We advised [center] we could continue to EGSS. Continued uneventfully to EGSS. We informed each controlling agency of our limitations and landed uneventfully. The First Officer (FO) remained pilot flying while the Reserve FO and I ran checklists. Reserve FO did an outstanding job running the checklist and backing us up on everything. FO did a great job also; flying the airplane while we had our heads buried trying to figure out if we could get an FMC back.

Air carrier flight crew reported a dual FMC failure shortly after flap retraction on departure. Flight diverted to an enroute field.
