Narrative:
On climb out through 12000 ft. We heard a bang from the left side of the airplane followed by a non-normal vibration. We noticed the number two engine rolling back. Captain assumed flying duties. I worked the radios. The observers handled the QRH. We complied with the non annunciated engine failure checklist in the QRH and secured the engine. We [advised] ATC; leveled at 15;000 ft. And setup return to ZZZ and emergency landing. ATC vectored us to runway xxr and we had a normal landing. We stopped on the runway. Airport fire rescue inspected the airplane for damage as well as a thermal scan for fire. We were given the all clear by airport fire rescue. We taxied to the gate and shutdown without further incident.crew all performed exactly as expected. We worked together as a team. The airplane flew well with one engine shutdown. We took our time and did not rush. ATC gave us exactly what we asked for and performed flawlessly. Airport fire rescue also provided exactly the support we needed. The non-annunciated engine failure checklist is hard to find in the QRH; especially during a stressful situation. At a previous airline; we had a catch all engine fire; failure; severe damage or separation checklist under the immediate action items section in the QRH.
