Agena D spacecraft 1169 was used for KH-5 Mission 9058A. As well as the ARGON mapping camera, 9058A carried a cosmic ray detector and a subsatellite listed in the SATCAT as `0.1 SQ METER TARGET'. ARGON 9 was launched on 1963 Aug 29 by a Thor Agena D from Vandenberg. Orbital mass was 1201 kg. The SRV was recovered in mid-air after 3 days of flight completing the most successful ARGON flight so far.

Corona 111
1966-072A
KH-4A Mission 1036 (CORONA 111) saw the introduction of a new launch vehicle, the Long Tank Thrust Augmented Thor Agena D. The LTTAT, also known as Thorad, was delivered by McDonnell Douglas to USAF in June of 1966, and took off from Vandenberg on Aug 9, placing the KH-4A payload into a retrograde 100 degree inclination orbit. The KH-4A mission had an unusually long duration, with SRV-1 recovered after 7 days and and SRV-2 operating for a further 6 days before recovery. This mission may be the first J-2 model,although the J-2 designation was not used in most documents. The J-2 proposal, reportedly not approved, used Thorad/Agena, had a 14 day lifetime, and could incorporate the OAS orbit adjust system kit. All of these enhancements apply to the later J-1 missions.

The first of three Mars-71 probes, M-71S (3MS) No. 170 was launched on 1971 May 10. M-71S No. 170 was a light version of the M-71 series. It was intended to enter Mars orbit. The Blok-D first burn successfully placed the probe in parking orbit, but the engine failed to ignite for the second burn because of a software error. The failed probe was designated Kosmos-419 and it reentered after two days.

Vela 1
1963-039A
Vela 1A (Satellite 1801; although this is also the Agena stage serial number and may be an error) was launched on 1963 Oct 17. It was a 1.4m dia icosahedron. The satellite had a mass of 135 kg after orbit insertion and carried a Hercules BE-3A kick motor modified from the Ranger retrorocket. The BE-3A may have had a mass of 90 kg.
Some sources indicate the Agena made two burns, with an initial 360 km parking orbit; however an Agena document history indicates only one burn was made on the Vela launches.
The early Vela satellites were spin stabilized. The April 1964 elements show periapsis at latitude 38S, suggesting transfer orbit apogee was there.
The X-ray scintillator detectors were also used for solar flux measurements by the LASL team. They covered the 0.5-15A (0.8-20 keV) range down to 10-3 erg/cm2/s and detected solar X-ray bursts (SR6, 893).

Soyuz 18A
1975-F02
Spacecraft 7K-T No. 39 was launched on 1975 Apr 5, carrying the second expedition to the DOS 4 space station, Vasiliy Lazarev and Oleg Makarov. Five minutes after launch, the R-7 core cutoff but failed to separate completely, as the Blok-I stage ignited. The dead weight of the R-7 dragged the launcher off course and the mission was aborted; the BO and SA of the spacecraft separated from the PAO, which remained attached to the Blok-I stage. The fairing was jettisoned and the spacecraft reached an apogee of 192 km before beginning a 20-g reentry. The BO separated from the SA. Then the SA, containing the crew, crash-landed in the Altai mountains 1574 km southwest of Gorno-Altaisk, in Mongolia and near the Chinese border. The flight had lasted 21 minutes and 27 seconds.
Under pressure from the US because of the upcoming ASTP launch, the failed launch was revealed by the USSR a few days later, but it was not assigned the Soyuz-18 name. Contemporary public Soviet announcements refer to it only as `Anomaliya Pyatovo Aprela', the April 5th Anomaly. The failure analysis rapidly gave the green light to ASTP, the Soviets claiming that the failure was specific to the older model of booster being used for the April 5 launch (it used the 11A511, while Soyuz-19 would use the newer 11A511U).

Gambit 10
1964-045A
In Jul 1964 Point Arguello Naval Missile Facility became part of Vandenberg Air Force Base, and so the Point Arguello GAMBIT pad LC2-4 became Vandenberg Air Force Base pad PALC2-4. KH-7 number 10 was launched from Vandenberg PALC2-4 aboard an Atlas Agena D on 1964 Aug 14. Spacecraft 960 separated from the Agena D 4808 rocket stage into a 149 x 307 km x 95.5 deg orbit. A pickaback scientific P-11 subsatellite was also ejected from the Agena stage. The SRV was recovered on rev 65 even though the last picture was taken on rev 23.

Corona 140
1970-098A
KH-4B Mission 1112 (CORONA 140) was launched on 1970 Nov 18 by Thorad Agena D from Vandenberg into an 83 deg inclination orbit. The forward and aft constant rotator panoramic cameras were units number 300 and 301, the qualification prototype J-3 units refurbished for flight - the system was designated QR-2R and it carried a load of both 3414 and 3404 type film. The satellite carried APL's Doppler Beacon 3 supplementary geodetic payload. Both SRVs were recovered. A study of this mission's imagery compared with earlier flights recommended that in future lower perigees of 148-167 km be used to increase the scale.
This was the first CORONA Agena to use High Density Acid and Hyperzine-300 instead of IRFNA/UDMH.

Explorer 46
1972-061A
The Meteoroid Technology Satellite, Explorer 46 after launch, was a NASA-Langley project designed to investigate technologies to protect satellites against meteor hits.
It was launched on 1972 Aug 13 at 1510 by Scout D-1 from Wallops. The heat shield was ejected at the unusually high altitude of 131 km to protect the delicate sensors. The fourth stage FW4S rocket ignited at 1519 and entered a 97.7 min, 492 x 811 km x 37.7 deg orbit. The MTS satellite remained attached to the FW4S. Two of the four primary panels were deployed, but two more did not extend and the spacecraft ended up tumbling at 3 rev per minute.
The velocity and flux experiments were concluded on 1972 Aug 22 because of problems with the telemetry system; insufficent data was obtained from the velocity experiment for meaningful analysis. After one year in orbit, the bumper experiment determined that the bumper is six times more effective than a single wall structure, even better than anticipated. The impact experiment showed that earlier microphone sensor experiments had overestimated the event rate. MTS transmitted until 1975 Jun 5 and reentered on 1979 Nov 2.
The satellite is a cylinder with four bumper arrays, 3.20m long 7.01m span. Mass is 206 kg, of which 168 kg is payload and 38 kg is FW4S and Scout D-section adapter.
