Baikonur LC110R

---

First Launch: 1969-02-21. Last Launch: 1969-07-03. Number: 2 . Longitude: 63.31 deg. Latitude: 45.96 deg.

• N1 launch pad 110 east completed - . Nation: Russia. Program: Lunar L3.

• N1 booster 4L erected at launch complex 110 east - . Nation: Russia. Program: Lunar L3.

  A September 1968 flight test was planned. However the first stage LOX tank developed hairline cracks during ground tests. 4L was removed from the pad in June 1968. The first stage was cannibalized; the upper stages were incorporated into the 1M1 mockup for further training of the launch crews.

• N1 1M1 mockup erected on pad with L1S payload - . Nation: Russia. Program: Lunar L3. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1. The N1 mockup was again erected on the pad, in order to conduct tests of the L1S payload in advance of the availability of the 3L launch vehicle..

• N1 launch vehicle 3L erected on launch pad - . Nation: Russia. Program: Lunar L3. The 3L vehicle, without its payload (which was on the 1M1 mockup), is erected on the pad to test engine systems..

• N1 3L launch - . Payload: Soyuz 7K-L1S s/n 3. Mass: 6,900 kg (15,200 lb). Nation: Russia. Related Persons: Afanasyev, Sergei, Dorofeyev, Kirillov, Mishin. Agency: RVSN. Program: Lunar L3. Class: Manned. Type: Manned spacecraft. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1A. Decay Date: 1969-02-21 . Apogee: 30 km (18 mi).

  N-1 serial number 3L was the first N-1 launched. The vehicle ran into trouble immediately at lift-off. A fire developed in the tail compartment. The engine monitoring system detected the fire, but then gave an incorrect signal, shutting down all engines at 68.7 seconds into the flight. British intelligence detected the launch attempt, but the CIA's technical means for some reason missed it and they denied for years that it had ever occurred. In retrospect the launch team at Baikonur pointed to a grave mistake - at the christening of the first N1, the champagne bottle broke against the crawler-transporter rather than the hull of the rocket. After the 3L failure everyone knew there was no chance at all of beating the Americans to the moon. Additional Details: here....

• N1 5L launch - . Payload: Soyuz 7K-L1S s/n 5 / Dummy LK. Mass: 6,900 kg (15,200 lb). Nation: Russia. Agency: RVSN. Program: Lunar L3. Class: Manned. Type: Manned spacecraft. Flight: Apollo 11. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-L1A. Decay Date: 1969-07-03 .

  N-1 serial number 5L began to fail at 0.25 second after liftoff when the oxidizer pump of engine number 8 ingested a slag fragment and exploded. A fire ensued as the vehicle climbed past the top of the tower. Engines were shutdown until the acceleration dropped below 1 G; then the vehicle began to fall back to the pad at a 45 degree angle. The escape tower fired at the top of the brief trajectory, taking the L1S dummy descent module away from the pad. Upon impact of the base of the N1 with the pad, the vehicle exploded, destroying launch pad 110 east, which would take over 18 months to repair. This was the end of a slight Soviet hope of upstaging the US Apollo 11. Additional Details: here....
