The production of operational missiles began during the final stages of the flight test program.
An operational specification SM-2 missile was launched from Vandenberg AFB LC-395-A3 on 21 January 1962, with the M7 missile launched on the last development flight from Cape Canaveral's LC-19 on 29 January 1962.
There were 59 XSM-68 Titan Is manufactured I in 7 developmental lots.
One hundred and one SM-68 Titan I missiles were produced to equip six squadrons of nine missiles each across Western America.
Fifty-four missiles were in silos in total, with one missile as a spare on standby at each squadron, bringing to 60 in service at any one time.

Titan was originally planned for a 1 X 10 (one control center with 10 launchers) "soft" site.
In mid-1958 it was decided that the American Bosh Arma all-inertial guidance system designed for Titan would, because production was insufficient, be assigned to Atlas and the Titan would switch to radio-inertial guidance.
The decision was made to deploy Titan squadrons in a "hardened" 3 X 3 (three sites with one control center and three silos each) to reduce the number of guidance systems required. (
Radio-inertial guided Atlas D squadrons were similarly sited).

Although Titan I's two stages gave it true intercontinental range and foreshadowed future multistage rockets, its propellants were dangerous and hard to handle.
Cryogenic liquid oxygen oxidizer had to be pumped aboard the missile just before launch, and complex equipment was required to store and move this liquid.

In its brief career, a total of six USAF squadrons were equipped with the Titan I missile.
 Each squadron was deployed in a 3x3 configuration, which meant each squadron controlled a total of nine missiles divided among three launch sites, with the six operational units spread across the western United States in five states: Colorado (with two squadrons, both east of Denver), Idaho, California, Washington and South Dakota.
 Each missile complex had three Titan I ICBM missiles ready to launch at any given time.
