Because even the dispersed storage and semi-buried coffins of the Atlas E offered insufficient protection, the USAF decided already in 1959 to deploy Atlas missiles in underground silos, just like the HGM-25A Titan I. This resulted in the SM-65F Atlas F missile, which was essentially an SM-65E with a modified fueling system to accomodate the new silo launcher. The first silo-stored Atlas F squadron became operational in November 1962. Because the SM-65F could be fueled while still in the silo, launch survivability was much improved. After fueling, it took only two minutes to raise and launch the missile. In a crisis, it was even possible to store the SM-65F fully fueled in the silo for some length of time, which lead to a reaction time of only five minutes. However, fueling in the silo was even more dangerous than in the open, and four Atlas Fs violently exploded during this operation, destroying their silos.

In June 1963, the existing Atlas missiles were redesignated in the xGM-16 series as follows:

Old Designation New Designation
SM-65D CGM-16D
USM-65D CTM-16D
SM-65E CGM-16E
USM-65E CTM-16E
SM-65F HGM-16F

There are also sources which claim that the SM-65Ds based on unprotected pads at Vandenberg AFB were redesignated as PGM-16D. While this would be logical, the PGM-16D designation was apparently never officially allocated. Also, reports claiming that XPGM-16A, XPGM-16B, and XPGM-16C were the new designations for XSM-65A, XSM-65B, and XSM-65C, respectively, are in error, because all three development models had long been expended by 1963. While the 1963 redesignations did include some "paper" designations of retired or cancelled missiles, this was not true for the Atlas series.

After the LGM-30 Minuteman had become operational in early 1963, the Atlas became rapidly obsolete. By October 1964, all Atlas D missiles had been phased out, followed by the Atlas E-F in April 1965. About 350 Atlas ICBMs of all versions were built, with a peak deployment level of 129 (30 D, 27 E, 72 F).

The Atlas was used as a space launch vehicle since the very beginning of the program, and Atlas developments are still used in this role in the 21st century. Converted ICBMs and early purpose-built space launchers, usually with additional upper stages, were used by the USAF under the basic SLV-3 designator. In 1990, the Atlas E, Atlas II and Atlas IIA-AS vehicles received the official military designations SB-1A, SB-2A and SB-2B, respectively. Current prime contractor for all Atlas rockets is Lockheed-Martin.

The vehicles converted for space launch use and launched from Vandenberg AFB used a radio guidance system that was based on a modification of the General Electric Radio Tracking System (GERTS), originally employed on the Atlas D. In fact, the GERTS guidance used for space launch employed one of the original radar stations used for the Atlas D and even used some actual Atlas D components in its Pulse Beacon Decoder, the vehicle's X-band radio transponder. Newer solid state computers were used to run the guidance software and were interfaced with the radar; eventually they were made redundant, although with a human operator charged with detecting failure.

The large Bosch-Arma pod on the side of the Atlas E and F space boosters launched from Vandenberg AFB from the mid-70's to the mid-90's was in fact empty. It was not removed and replaced with a more streamlined fairing since that would have cost money and gained no significant performance. So, the Atlas E and F space boosters used Atlas E and F ICBM airframes and engines with the tanks modified with a new payload interface section, a mixture of Atlas E and F components (selected based on which designs were most suitable for the space launch mission) and a modified Atlas D radio guidance system.

GERTS was a complex, glitch-prone system, its only saving graces being that it was both the cheapest guidance system around and the most reliable, operating for almost 30 years without one flight failure and at a per-flight cost an order of magnitude below that of an inertial guidance system. Prior to Apollo-Saturn, all U.S. manned orbital flights used GERTS, both on the Mercury-Atlas D and the Gemini-Titan II missions.

The proper way to refer to the space booster Atlas E's and F's was "Atlas E-F Space Booster," because of the mix of configuration features. Of course, individually the boosters were referred to by their "Tail Numbers" such as 19F, 76E, 68E, etc. The total launched cost of an Atlas E-F space booster was about $15M - or less than 1-3 the cost of a Titan II space booster, and less than 1-20th what was finally admitted as the cost of a single Space Shuttle mission. About 35 unmodified Atlas E-F missiles in storage at Norton AFB were scrapped in the early 1970's. The Space Shuttle was coming and it was assumed that they were not needed. The cost of maintaining them in storage was "horrendous" - about $2000 each per year. At least a half billion dollars worth of perfectly usable, incredibly cheap space boosters (equivalent to a couple of billon dollars in replacement costs) were run over with a bulldozer in order to save perhaps one million dollars in storage costs overtwenty years . The Air Force officer who recommended this travesty of planning received a medal for his farsightedness.

1980 May 29 - . 10:53 GMT - . Launch Site: Vandenberg. Launch Complex: Vandenberg SLC3W. LV Family: Atlas. Launch Vehicle: Atlas F. LV Configuration: Atlas F 19F / Star-37S-ISS. FAILURE: Atlas sustainer engine under-thrust resulted in 50 second extended burn time, and spacecraft attempted to separate and fired apogee kick motor while booster was still thrusting.. Failed Stage: P.

USAF Sat Cat: 11819 . COSPAR: 1980-043A. Apogee: 1,445 km (897 mi). Perigee: 264 km (164 mi). Inclination: 92.2000 deg. Period: 102.10 min. Unusable orbit; would have been NOAA 7. At engine start up, one of the booster engines suffered an internal fuel leak, causing it to run at about 80% thrust. As a result the booster was low on velocity and heavy on propellant over much of its flight and ran an incredible 50 seconds longer than the nominal burn. The NOAA Advanced TIROS payload was designed with no direct communication with the booster, and unaware of the booster problem, at 375 sec after liftoff attempted to separate with the booster still firing. The booster's continued thrusting defeated the payload's attempt to perform the required pitch maneuver. When the payload fired its apogee kick motor, it blew the top of the booster's liquid oxygen tank off. The spacecraft survived all this, but the resultant orbit was highly elliptical rather than the desired circular sun-synchronous. The mission was a total loss.
