continued to fly until T+126 seconds when it began to drift off its flight path, leading to an automatic shutdown command. On June 20, a few weeks later, a 4K1 (Oktan) launched from
Plesetsk's LC-16 and met nearly the same fate when again the payload fairing disintegrated 50 seconds after launch. This time the onboard destruct system on the satellite activated and destroyed it, after which ground controllers sent a manual shutdown command to the booster, which crashed 4 miles (6 kilometers) from the pad. The back-to-back failures were traced to a manufacturing defect in the payload shrouds, which were produced in a batch, and they left Russia's ability to perform military reconnaissance severely hampered. In both cases, the shrouds broke up at the point of maximum aerodynamic pressure during ascent.

Yantar-4K1 was a modification of the Yantar-2K. It had a better camera, the
Zhemchug-18, and was in orbit for 45 days rather than the 30 days of Yantar-2K. Other systems were the same as the Yantar-2K and both types of satellites were launched in the same period. Both satellites were retired in 1984.

The Yantar program produced two memorable launch accidents. The first of these was on May 15, 1996 when an attempted launch of a 1KFT (Kometa) at
Baikonur's LC-31 failed 50 seconds after liftoff when the payload fairing disintegrated. The satellite was destroyed by aerodynamic forces, but the booster

Zhemchug-4 (pearl) camera. Each section was shaped like a truncated cone which gave the craft a conical shape. The craft was 6.3m long (although one source says 8.5m) with a maximum diameter of 2.7m. It weighed 6.6 tonnes.

Yantar-2K differed from Zenit in that it had to stay in orbit for a month unlike Zenit's 8–14 days. It also had two film return capsules, something it had in common with the US
