B777 flight crew reported temporary loss of aircraft control during departure in an area of convective weather.
Synopsis
B777 flight crew reported temporary loss of aircraft control during departure in an area of convective weather.
Narrative
Upon taking the runway; Tower asked if we could maintain SID profile to ZZZZZ on departure. We observed the radar and said we would request right of course; as there was a cell over ZZZZZ. Tower said unable. She then asked again if we could maintain SID to ZZZZZ. We accepted the clearance with the intent to request vectors prior to ZZZZZ. Two aircraft departed prior to our departure on the same path with no PIREPs reported. Approaching ZZZZZ; and entering the cell; airspeed began increasing slowly. After 30 seconds; the airspeed decreased rapidly and we received a LOW AIRSPEED EICAS; followed by a momentary stick shaker. First Officer maintained control. We then requested multiple vectors to avoid further build ups. ATC insisted we take a turn north prior to what we had requested due to ZZZZ airspace. Cause: Weather and ATCSuggestions: ZZZZ Departure would not allow any deviation from the SID which caused us to fly into the weather that resulted in AIRSPEED LOW caution with momentary stick shaker. In hindsight; we should have requested priority handling and deviated from the SID to go around the weather. Do not let ATC drive you into a dangerous situation.
