T+0:00:00	Liftoff
The twin Solid Rocket Motor Upgrade (SRMU) boosters are ignited and the Titan 4B rocket launches from Complex 40 at Cape Canaveral Air Force Station, Florida.
T+0:00:07	Roll Program
Rocket beings a roll maneuver to the flight azimuth of 93 degrees for the travel downrange from launch site.
T+0:02:11	Stage 1 Ignition
The Titan 4B rocket's core vehicle stage 1 engine package -- the Aerojet LR87-AJ-11 -- is ignited. The liquid-propellant powerplant burns Aerozine-50 fuel and nitrogen tetroxide oxidizer.
T+0:02:27	SRMU Separation
Having consumed all their solid-propellant, the two Alliant Techsystems-built solid rocket boosters are jettisoned to fall into the Atlantic Ocean.
T+0:03:36	Jettison Payload Fairing
The tri-sector payload fairing buit by Boeing that protected the Milstar satellite during launch is separated once heating levels drop to predetermined limits.
T+0:05:25	Staging of Titan Core
The first stage engine shuts down and the second stage Aerojet LR91-AJ-11 engine is ignited. The spent first stage is jettisoned from the rest of the space-bound Titan 4B rocket one second after the second stage is started.
T+0:09:15	Stage 2 Shutdown
The liquid-fueled second stage engine completes its firing and begins a momentary coast period before deployment of the upper stage and Milstar payload.
T+0:09:23	Stage 2/Centaur Separation
The Lockheed Martin-built Centaur upper stage is released from the Titan rocket's core vehicle, which has completed its role in the launch.
T+0:09:44	Centaur Burn 1
The liquid-fueled Centaur stage is ignited for the first of three firings needed to deliver the Milstar satellite into the desired geostationary orbit.
T+0:11:44	Centaur Cutoff 1
The Centaur completes its first burn to achieve a stable low-Earth orbit with the attached Milstar satellite.
T+1:05:02	Centaur Burn 2
After quiet coast period through space, the Centaur stage is restarted in the first of a two-step process to propel Milstar in geostationary orbit.
T+1:10:16	Centaur Cutoff 2
The Centaur engines are shut down following the firing that should raise one side of the orbit to geostationary altitude of 22,300 miles.
T+6:23:05	Centaur Burn 3
Following a lengthy coast to the high point of its orbit -- around geostationary altitude -- the Centaur engines are again reignited to circularize the orbit by raising the low end of the orbit. This will deliver Milstar into a geostationary orbit 22,300 miles above the planet.
T+6:25:17	Centaur Cutoff 3
Shut down of the Centaur engines occur to complete the powered phase of this launch. The stage now prepares to release the Milstar satellite. Centaur will later perform a collision avoidance maneuver, propellant blowdown and hydrazine depletion after spacecraft separation.
T+6:35:30	Spacecraft Separation
The Milstar 2-F3 secure military communications satellite is deployed into space from the Centaur upper stage to complete the Titan B-38 launch.
