No direction on space from new Soviet leadership. - . Nation: Russia. Related Persons: Bushuyev, Korolev, Okhapkin. Program: Lunar L1, Voskhod, Soyuz. Spacecraft: LK-1, Soyuz 7K-OK, Voskhod.
After the triumph of the Voskhod-1 flight, Korolev gathers a group of his closest associates in his small office - Chertok, Bushuyev, Okhapkin, and Turkov. Firm plans do not exist yet for further manned spaceflights. Following the traditional Kremlin celebrations after the return of the Voskhod 1 crew, he has heard no more from the new political management. Khrushchev's old enthusiasm for space does not exist in the new leadership. Korolev is angry. "The Americans have unified their forces into a single thrust, and make no secret of their plans to dominate outer space. But we keep our plans secret even to ourselves. No one has agreed on our future space plans - the opinion of OKB-1 differs from that of the Minister of Defense, which differs from that of the VVS, which differs from that of the VPK. Some want us to build more Vostoks, others more Voskhods, while within this bureau our priority is to get on with the Soyuz. Brezhnev's only concern is to launch something soon, to show that space affairs will go better under his rule than Khruschev's." Korolev however does not think the new leadership will support continuation of Chelomei's parallel lunar project. Okhapkin speaks up. "Do not underestimate Chelomei. He is of the same design school as Tupolev and Myasishchev. If we give him the will and the means, his products will equal those of the Americans. Now is the right moment to combine forces with Chelomei".

1966 March 6 - .

Soviet design bureaux reorganised and renamed. - . Nation: Russia. Related Persons: Afanasyev, Sergei, Mishin, Okhapkin. Spacecraft: LK, Soyuz 7K-L1, Soyuz 7K-LOK, Soyuz 7K-OK.
Decree 'On renaming OKB-1 as TsKBEM and OKB-52 as TsKBM' was issued. In 1966 Afanasyev reorganised the military industrial complex. OKB-1 was redesignated TsKBEM. Sergei Osipovich Opakhin was made First Deputy within the new organization.
However within TsKBEM there were no relative priorities for the projects competing for resources. The R-9 and RT-2 ICBM's, the orbital, circumlunar, and lunar orbiter versions of Soyuz, the LK lunar lander, the N1 booster -- all were 'equal'. It seemed folly to be pursuing the orbital ferry version of the Soyuz when no space station had to be funded. But it was felt flying the spacecraft would solve reliability questions about the design, so it was pursued in parallel with the L1 and L3 versions.

1966 May 11 - . Launch Vehicle: N1.

Mishin selected as Korolev's replacement after four-month delay - . Nation: Russia. Related Persons: Babakin, Keldysh, Khrushchev, Korolev, Mishin, Mozzhorin, Okhapkin, Ustinov. Program: Lunar L3, Lunar L1. Flight: Soyuz 1, Soyuz 2A. Spacecraft: LK, Soyuz 7K-LOK.
From 1963-1965 Ustinov was both head of the Soviet for the National Economy and the First Secretary of the Presidium of Soviet Ministers. He supported civilian space projects and instructed the military to co-operate in them. But after Khrushchev was ousted, Ustinov had less influence with the Ministry of Defence.
After the death of Korolev in January, a letter was sent to the Central Committee requesting that Mishin be appointed director of OKB-1. Ustinov tried to line up support for Mishin, but by the time of the first first Saturn IB orbital flight on 26 February 1966, no decision had been made. America was progressing on the path to the moon, but Russia was stalled. An alternate that had been considered was Sergei Okhapkin, another Deputy Chief Designer at TsKBEM. But Okhapkin knew only spacecraft, he had never developed complete launch-booster-spacecraft systems. By the time Mishin was appointed, it was clear that the race was lost. The American's planned their first Saturn V launch in September 1967 and their first manned flight in 1968. Mishin could not expect trials of the LK lunar lander until 1969 at the earliest. There were insufficient funds allocated, and the schedule had no allowance for test flight failures. Ustinov, Morozhin, and Keldysh pointed fingers as to who had presented such unrealistic schedules to the Politburo. Keldysh now supported unmanned robot lunar landers in development by Babakin. Even these would not land until 1970, allowing three years of flight trials to achieve reliability. Khrushchev, it seemed, was to blame for such enormous unaffordable projects. This in turn put Ustinov in danger, as Khrushchev's point man for space.

1967 December 8 - .

TsKBEM confirms Mishin's decision to cancel Soyuz VI - . Nation: Russia. Related Persons: Bushuyev, Chelomei, Feoktistov, Gaidukov, Karas, Kerimov, Mishin, Okhapkin, Shcheulov. Program: Almaz. Spacecraft: Almaz OPS, LK-1, Soyuz 7K-S, Soyuz OB-VI, Soyuz VI.
Mishin is away on 'cure' for his drinking problem. A 'Podlipki Soviet' is held at TsKBEM. The issue is cancellation of Kozlov's 7K-VI military Soyuz. Bushuyev, Chertok, Okhapkin, Feoktistov are in favour of cancelling it. Opposed are Karas, Shcheulov, Kostonin, Gaidukov, and the various military representatives at the meeting. It was now six years since OKB-1 was required to put a military manned spacecraft into space - and, factually speaking, nothing has been done. Military experiments proposed for each manned flight by OKB-1 to date had been rejected on various grounds - no weight, no space aboard the spacecraft. Good progress has been made with Kozlov's VI and Chelomei's Almaz - now they've managed to kill the VI, and Mishin and Kerimov are constantly denigrating Almaz (saying it is too heavy, and unsuited for the purpose). The whole thing is a replay of the LK-1 situation. In 1963, a resolution was issued to send a Soviet man around the moon. Instead, after two years of development, Korolev managed to get Chelomei's LK-1 lunar spacecraft cancelled, and started all over with his own L1. Additional Details: here....

1968 January 28 - . Launch Vehicle: N1.

Sergei Osipovich Okhapkin put in charge of the N1 at TsKBEM - . Nation: Russia. Related Persons: Mishin, Okhapkin. Program: Lunar L3. This decision led to one of Mishin's famous 'illnesses', putting him out of action for a period..

1968 December 30 - .

How to beat the Americans to the lunar landing - . Nation: Russia. Related Persons: Babakin, Chelomei, Keldysh, Mishin, Okhapkin, Pilyugin, Ustinov. Program: Lunar L3, Lunar L1, Luna. Spacecraft: LK-1, Luna Ye-8-5, Soyuz 7K-L1.
Meeting of the VPK Military-Industrial Commission to discuss how to beat the Americans to the lunar landing Ustinov called the meeting to order. Mishin was 'sick' again -- Okhapkin represented TsKBEM and gave a summary of the programme to that date:
- The project had only been authorised on 3 August 1964. It consisted of two parts, circumlunar flights using Chelomei's UR-500K booster and LK-1 spacecraft, and a lunar landing using Korolev's N1 booster and L3 spacecraft.
- On 25 October 1965 the programme was redirected. Military support was ordered and the decision was made to cancel Chelomei's LK-1 spacecraft and instead use the L1 version of Korolev's Soyuz for the circumlunar flights. This was ordered by the resolution 'On organisation of construction units for support of rocket-space systems for the lunar flyby'. That resolution ordered a manned L1 flight by the end of 1967 or early 1968.
- The program actually took three years to implement rather than the two planned. Nine launches of he L1 had been made since March 1967, but it had not been possible to man-rate the UR-500K/L1 booster/spacecraft combination due to failures in both the launch vehicle and spacecraft. Flight trials of the N1 booster had not even begun yet.
  Keldysh proposed that further work on the L1 be abandoned, and Proton boosters instead be used to launch the Ye-8-5 lunar soil return robot spacecraft being developed by Babakin. Babakin had been accelerating this programme since the beginning of 1968 with the support of Keldysh, even though it would only return around 100 g of lunar soil, versus the tens of kilograms the Apollo manned flights would return. However it now offered an interesting possibility - he proposed obtaining lunar soil and returning it to earth before an American manned landing. The government's organs of mass communication would say that the Soviet Union's lunar program only consisted of robot probes, emphasising that his was much safer and that Russia would never risk it's citizen's lives for mere political sensation.

1969 January 29 - .

Debate on post-Apollo 8 Soviet priorities. - . Related Persons: Mishin, Chertok, Feoktistov, Okhapkin, Bezverby, . Spacecraft: MKBS, TOS, TMK.
SO Okhapkin: I do not agree with the first part of the speech of VP Mishin. We accepted obligations and have not fulfilled them. We deceived the Central Committee and the government with the second part of the performance agreement. These will have terrible consequences (no communication satellites or MKBS, etc.)
KP Feoktistov: Orientation toward Mars - is correct. We will achieve Mars - and the moon, and the TOS heavy space station. The OKB should complete the ordered spacecraft, all the systems, and ordered launch vehicles... the TMK - for Mars, the Moon and the MKBS (cover for weapons systems development)
Chertok: It is good that the program proposed by the Soviet of Chief Designers was approved unanimously. Big manned spacecraft to Mars (and from that to derive standard modules with automatic options for Earth manned flights.) MKBS - for defense purposes.
VK Bezverby: Use EYaRD nuclear electric propulsion for deep space missions and MKBS (for defense purposes). (Mishin Diaries 2-162)

1969 May 29 - .

N1 State Commission - . Nation: Russia. Related Persons: Afanasyev, Sergei, Barmin, Bushuyev, Chelomei, Keldysh, Mishin, Nadiradze, Okhapkin, Pashkov, Smirnov, Tyulin, Yangel. Program: Lunar L3. Spacecraft: Aelita satellite, LK, Soyuz 7K-L1A, Soyuz 7K-LOK.
Over two days a State Commission reviewed all of the conclusions of the N1 3L failure investigation and the readiness of N1 5L for flight. All of the fixes identified to remedy the 3L failure had been incorporated into 5L. It was felt that the behaviour of the systems in fire conditions were understood and appropriate measures had been taken. The wiring had been rerouted and insulated. Barmin wanted the system not to shut down any engines under any conditions during the first 15-20 seconds of flight, so that the booster would clear the pad and there would be no risk of the pad's destruction. But there was no time to develop such measures before the 5L launch; it could only be added in vehicle 6L. Additional Details: here....

1970 July 26 - .

Organize the work of designers (those needed and useful) for blocks Sr, S and MKBS. - . Related Persons: Mishin, Chertok, Bushuyev, Bushuyev, Feoktistov, Okhapkin. Spacecraft: , MKBS. Okhapkin, Bushuyev Chertok, Bezverby, Kolyako, Feoktistov, Timchenko, Legostaev - have to involved. (Mishin Diaries 2-300).

1971 May 17 - .

MOK, MKBS, nuclear power supply reviewed. - . Related Persons: Mishin, Okhapkin, Bezverby, Melnikov. Spacecraft: , MKBS, Mir.
Bezerby VK and Melnikov MV - Materials on the experimental base for EYaRD. Okhapkin SO - About the acceleration of work on blocks R and Sr. Call Karpov AG - On specifications for MKBS-1. The development of the MOK should be conducted in full swing, but testing of individual systems should be conducted on the MKBS-1 (DOS). The main question - how long can a man live in space, and what can he do better than automatic systems? (Mishin Diaries 2-330)

1972 August 21 - . Launch Vehicle: N1.

N1 7L State Commission - . Nation: Russia. Related Persons: Afanasyev, Sergei, Kuznetsov, Lapygin, Mishin, Okhapkin. Program: Lunar L3. Spacecraft Bus: Soyuz. Spacecraft: Soyuz 7K-LOK.
The State Commission was held to verify readiness of N1 7L for launch. Mishin was 'sick' the whole week of the hearings and had to be represented by his deputies. However neither Mishin or his first deputy Okhapkin were available - both were in the hospital. The commission nearly ruled that until Mishin was available, no launch could be approved. However the review continued. Additional Details: here....

1980 March 1 - .

Death of Sergei Osipovich Okhapkin - . Nation: Russia. Related Persons: Okhapkin. Russian engineer. Deputy Chief Designer 1952-1976 of Korolev design bureau. Led work on the N1 and was Mishin's First Deputy..
