Aircraft
Right after takeoff passing about 500 feet we lost auto throttles; They would not re-engage. Soon after; we noticed we had lost electric trim. We engaged the autopilot and discovered the 'Stab out of trim' light on the forward panel illuminated. We continued hand flying the aircraft and referenced the QRH 'Stabilizer out of trim' checklist. This checklist led us to 'Stabilizer trim inoperative ' checklist. We got a phone patch to Dispatch and Maintenance Control. The HF frequency(s) given were hard to use. Hard to understand; and dropped off repeatedly. At this point we had no autopilot; no auto throttle; we were manual trimming. Things to consider: at some point we had [advise ATC] and make a flaps 15 landing; we were heading out over the water where company communications would be difficult. Per Dispatch; the weather on the coast prevented any deviations until ZZZ north. We would have to get a waiver to enter RVSM airspace because we didn't have an autopilot; potentially affecting the fuel burn. If we continued on to ZZZ1 we would be making a landing in marginal weather after a very long day. Deviating to an airport in the [area] was the best choice. Discussed issues with Dispatch and ZZZZ; was chosen because of potential Customs issues. Dispatch called the station and coordinated what was needed. We [advised] ATC and diverted to ZZZZ. We configured early to burn as much gas as quickly as possible; and when light enough we landed uneventfully at ZZZZ.
