Pitch and yaw programs have started according to plan.
You're hearing Patrick Moore provide launch vehicle ascent data from Vandenberg's telemetry lab.

SRBs have burnt out. Standing by for jettison momentarily.
And there's separation of both boosters. That occurred at the T+1 minute, 40 second mark.

T+2 minutes. Delta IV now being powered solely by the RS-68A engine, which is burning propellant at the rate of about 936 kilograms per second.

T+3 minutes. Altitude 113 kilometers, speed 2,414 meters per second, downrange distance 101 kilometers.
Both fairing halves have been jettisoned, exposing the NROL-47 payload to the vacuum of space. The webcast in the process of closing even though we're still in the first stage powered portion.

The RS-68A engine should be in the process of throttling down in preparation for MECO.

4 minutes Mission Elapsed Time. MECO should have occurred at this time, which is usually followed by stage separation about 8 seconds later.
After stage separation, the RL-10B-2 engine should ignite for a long first burn, which is preceded by the engine nozzle extending into place during the short coast phase.
