'...The first in-silo launch of a liquid fueled ICBM, Titan VS-1, code named "Silver Saddle," and carrying a dummy second stage from the Silo Launch Test Facility (SLTF). The test was to confirm the silo launcher configuration and the feasibility of launching from within an underground silo...' Silent.

The Martin Marietta SM-68A/HGM-25A Titan I was the United States' first multistage intercontinental ballistic missile (ICBM), in use from 1959 until 1962. Though the SM-68A was operational for only three years, it spawned numerous follow-on models that were a part of the US arsenal and space launch capability. The Titan I was unique among the Titan models in that it used liquid oxygen and RP-1 as propellants. All subsequent versions used storable propellants instead.

Originally designed as a backup in case Air Force's SM-65 Atlas missile development ran into problems, the Titan was ultimately beaten into service by Atlas. Deployment went ahead anyway to more rapidly increase the number of missiles on alert and because the Titan's missile silo basing was more survivable than Atlas...

Flight testing

The Titan I flight testing consisted of the first stage only Series I, the cancelled Series II, and Series III with the complete missile.

A total of 62 flight test missiles were constructed in various numbers. The first successful launch was on 5 February 1959 with Titan I A3, and the last test flight was on 29 January 1962 with Titan I M7. Of the missiles produced, 49 launched and two exploded: six A-types (four launched), seven B-types (two launched), six C-types (five launched), ten G-types (seven launched), 22 J-types (22 launched), four V-types (four launched), and seven M-types (seven launched). Missiles were tested and launched at Cape Canaveral Air Force Station from Launch Complexes LC15, LC16, LC19 and LC20...

On 2 February 1960, LC-19 returned to action as Missile B-7 marked the first successful flight of a Titan with a live upper stage...

On 1 July, the newly opened LC-20 hosted its first launch when Missile J-2, an operational prototype, was flown. Unfortunately, a broken hydraulic line caused the Titan's engines to gimbal hard left almost as soon as the tower was cleared. The missile pitched over and flew onto a near-horizontal plane when Range Safety sent the destruct command at T+11 seconds. The burning remains of the Titan impacted 300 meters from the pad in an enormous fireball. The piece of plumbing responsible for the missile failure was retrieved—it had popped out of its sleeve resulting in loss of first stage hydraulic pressure. The sleeve was not tight enough to hold the hydraulic line in place, and the pressure being imparted into it at liftoff was enough to pop it loose. Examination of other Titan missiles found more defective hydraulic lines, and the Missile J-2 debacle caused a wholesale review of manufacturing processes and improved parts testing.

The next launch at the end of the month (Missile J-4) suffered premature first stage shutdown and landed far short of its planned impact point. Cause of the failure was a LOX valve closing prematurely, which resulted in the rupture of a propellant duct and thrust termination. Missile J-6 on 24 October set a record by flying 6100 miles. The J series resulted in minor changes to alleviate the second stage shutting down prematurely or failing to ignite...

The warhead of the Titan I was an AVCO Mk 4 re-entry vehicle containing a W38 thermonuclear bomb with a yield of 3.75 megatons which was fuzed for either air burst or contact burst. The Mk 4 RV also deployed penetration aids in the form of mylar balloons which replicated the radar signature of the Mk 4 RV...
