please guys did u think with yourself??? until when we have to talk about analog system! we can show our skill's about control better system! it not soon for us. we can if we have First - this should be in "Future plans" topic... Second - SA-6 is analog too... And what skill you will "show", when using a robot, which decides alone what and when to kill... And your "skills" is just to switch on and switch it off... Great skills... first - i realy tnQ dear piston! congratulation u open S*HI*I*T bottle on my head second - nothing!

What happened when push "Vozvrat" and we have a V-760 missile in the air? K1/2 commands are no longer emitted, and the missile fells.

Here V-760 ... The G-force of the launch initiated the clock for self destruction mechanizm.When the O component acheved 20 atm before the missile motor it removes first lock. Also when inertional g-force starts to decrease (exhausted fuel), the self-destruction timer also starts. On the 10-th second of the missile flight PMK-60 (53 & 53a)starts and powered up with +26V in the warhead and prepared it to detonation. When missile reached ~2 km altitude, barometric sensor activates the self-destruction mechanizm in case of height loss.
On 6-8,5 km altitude another barometric sensor deactivates the second lock of the warhead.
On 20-th second after starting, PMK-60 (53 & 53a), warhead is powered up and ready for detonation.
K4 removes third lock. K3 detonates the warhead.
If there is a miss, on the 81+/-6 second the timer activates "passive timer self-destruction" of the missile. If there is a miss and altitude drops under 2 km, barometric sensor activates "passive height self-destruction"...
Some elements from V-755:

This should be the "SAMIN", right? Those missiles are really tough - I knew that they shouldn't stay long time with fuel and oxidizer, they should be emptied and washed inside, because of the high corrosive fuel... And this one is even bombed... My bet was ... AK-20K “Melanj” oxidizer (“O” substance)Composition: Nitric Tetroxide in solution with Nitric Acid, with Phosphoric and Fluoric acid inhibitors. 20±2,5% N2O4, 73,4% HNO3, 1-1,25% H3PO4, 0,5% HF, 2±0,8% H2O Orange-brown, evaporating liquid. Self ignites combustibles. Highly corrosive, only few materials can withstand its effect: chromium steel, pure aluminum, glass, and for a short period, some rubber mixes.

Most definitely. See the orange-brown fumes? They are all sorts of nitrogen oxides which do a jolly good job of oxidizing lungs when inhaled. And apparently there have been several nasty accidents since it is necessary to empty and refuel rockets at regular intervals. At least they don't do much of environmental damage once they are done oxidizing.
Nitric tetroxide is the best reason for solid fuel rockets.
Edit: Having fluoric acid listed as "inhibitor" should be a sure sign to STAY AWAY from this.

A question just occurred to me about the SA-2.
How does the system track the missile it's launched when the system's radar isn't transmitting? Especially knowing the missile's range?

Please, check the manual for SA-2 from Vintorez... Also discussed in the old topic (using "Search" option is a good idea too..) I read the manual AGAIN. And I didn't find an answer AGAIN I searched the forum AGAIN. And I didn't find an answer AGAIN. Since you seem to know the answer, could you please just tell me or at least give me a link to the right place?

In angles, the wide beam antennas are continuously receiving the missile beacon. (you can check it on the "A" panel, with the Target/Missile switch) In range, the system uses a time/range mathematical function to approximate missile range.

I read the manual AGAIN. And I didn't find an answer AGAIN It was in the manual from Vintorez: Missile channel jamming story: Such jamming did have effect versus early Dvina V-750VK missiles in Vietnam. Between December 1967 and February 1968, literally hundreds of Vietnamese missiles went out of control right after launch. SNRs were unable to locate their missiles as their relatively weak transponder (transmitters of back-facing reply signal from the missile towards SNR which made them visible) signal was suppressed by very effective USAF’s QRC-160-8 jamming pods. Soviets reacted quickly after an example QRC-160-8 was salvaged from a downed F-105 in February 1968 - solution was to double the missile marker number of pieces, and increase its output with the introduction of the V-750VM/VMK missile type. Since then, missile channel jamming was ineffective. Interestingly, the US TAC HQ learned this, and the Weasels/F-4's were not jamming this channel for several years. However, this info was lost in the USAF organization, so SAC HQ had no knowledge of it. As late as during Linebacker II in 1972, all B52s were still instructed to jam the missile downlink signal channel, using up - for no effect – their valuable jammers which could otherwise had been tuned to deal with SNR target tracking. I've searched back the forum, but didn't find where was discussed, so sorry being stubborn...

Here on polish: http://infowsparcie.net/wria/o_autorze/elab_rakiet.htmlHere some memories about using the nuke-tipped missiles: http://www.kap-yar.ru/index.php?pg=443 Operation "SAM-215" As noted, during the second half of the 50's, in connection with the development of air defense with nuclear warheads are interested for the nuclear explosion at an altitude of alleged use of missiles of these complexes (10 km ≤ N ≤ 40 km). First in a series of explosions had a blast, conducted "Operation SAM-215." It was produced on 1/19/57 at noon on rocket range MO Kapustin Yar. Was selected for the explosion charge with energy 10 kt successfully tested earlier. The charge was set to anti-aircraft guided missile SAM-215, on behalf of which the operation is called. Automatic docking was done to undermine the charge and missile control systems, as well as a series of pre-launch of a missile with the models of the charge. The point of impact was a transponder beacon, thrown off before putting on a parachute airplane security. Undermining the nuclear missiles was planned to make a charge at a time when the transponder beacon parachuted into a height of 10.4 km. To obtain direct information on the effectiveness of the harmful effect of a nuclear explosion in the area of ​​the aiming point before the start of combat missiles aimed two radio-controlled target aircraft in such a way that at the time of the explosion, they were away at a distance of about 500 m and 1000 m as aircraft targets were equipped with radio control system and means of recording combat aircraft IL-28. For registration of parameters affecting the effects of nuclear explosions at close range was created so-called TARGET 16 special conditions of cylindrical containers, equipped with measuring devices. Containers were dropped by parachute advance support aircraft so that the explosion of which 12 were at approximately the height of the explosion at various distances. The remaining 4 konteynepa housed at other altitudes. The containers were installed devices that record the pressure in the passing shock wave (pressure recorders), penetrating radiation (gamma-ray detectors and neutron flux), the pulse light (calorimetry). The actual position of containers at the time of the explosion of the nuclear charge and the position of the point of explosion was determined by the results of a ground-based photography in several ways, namely by direct resection. Aerial cameras used for photography. There was also a set of ground stations deployed to measure the shock wave light (spectrum, integrated fluxes, timing), and penetrating radiation. Near ground zero and several other points were constructed of wooden models of buildings. To measure the power of the explosion using the same set of procedures as for conventional air explosions. Overall, the experience was a success: its main tasks to execute. Energy charge in the experiment was 10 kilotons. Height of the explosion point, determined by a straight serifs, to 10.37 km. "Target" of the situation in the most appropriate to a calculation: both aircraft "IL-28" and most of the containers at the time of the explosion were at given points to 0.1 km, and only the first row of containers was located twice as far from the point of explosion than planned. This situation prevented the measurement of effects of explosion, where they would be the most powerful.
The explosion of both aircraft were shot down by the target: one of them, who walked away from the center of the explosion, burst into flames, the second, who was walking towards virtually shock wave broke off the wing.Measuring equipment on each of the planes worked fine, and the results of measurements by telemetry failed to transmit to the ground. These results are further used to determine the criteria and the affected areas of aircraft in nuclear explosions. Ground-based observatories is not a single case of a significant effect of an explosion on the wooden structures and glazing.
