"Having started my service in the PVO on the complex 5N87 , I have often provided technical assistance to the divisions of the repairing their radars and PRV-s. Each year, part went to the ground, often in Sary- Shagan. Once at the site right on the day of shooting I was urgently sent to the position of the S -75 to help set up the altimeter PRV- 13 , with which the commander of intelligence battalion suffered for two days. It turned out that the crews, which have been here for training had "simplified" PRV- 13 and "refined" it so much that it swinging , rotating, and transmitting starts simultaneously. Dehydrator did not exist, and the liquid cooling system howling, driving the tubes some haze .
If it were possible to draw a diagram of the control cabin of PRV , it would fit on
A4 sheet . Rotary amplifier when the rotation was buzzing like a siren ,
because all of its automatic step connection replaced 3 sticks that need
was successively inserted into the contactor .
Where was the trailer B2 with dead potentialoscope no one knew and did not look for it, whilst there was a trigger pulse . Most importantly, the PRV was alive..... High power switching only at the minimum , in an attempt to increase the power thyratron TGI1 -700 / ... started to shoot and flashed like a neon lamp, AFC has worked in a continuous mode , switch to another channel was not possible because of the absence of the VG- 12 adjustment mechanism and also waveguide switch was tightly bound with wire in one position. Receiver after the adjustment to the normal frequency of the mirror started to work fine, but only in the amplitude mode , confidently showing local objects . With the swing had to tinker a little longer .
Modified by someone automation cabinet CM -23 antenna forced to start swinging
conjunction with a hydraulic pump , so do not have enough pressure and antenna sharply
fell to a lower limit switch , had to first remove the amplitude and wait "Kach.30" mode
until the water pump spin up , then to adjust the swing . "CAUTION " lamp in this PRV is triggered even when you open the cabine door , I thought it was a joke or pore PRV, begged him not to be touched anymore.
Luckily, after couple of hours repairing and adjustments the altimeter managed to find at a decent range aircraft
on the air root Almaty - Karaganda . We all sigh of relief but the battalion commander decided not to switch PRV
off until the end of practice shooting, in case it didn't manage to start working again....
And still running in the morning 'till afternoon PRV frightened squirrels with it's swinging' antenna and howling hydraulics.
An hour before the shooting on the CP raised the red flag and then we buzzed the whole SAM unit - rotating
P-18, SNR moved, crew loaded rockets, launchers deployed in a combat sector. Combat crew took their seats in the cabins, green screens lit up with an officer pointing and operators of RS. In the "U" cabin of S- 75 were remote indicators of the P-18 and a wardrobe of PRV that provide info for guidance station . When they announced the readiness minute , for half an hour PRV already searched the area near the point of known azimuth from a range of 95 km were the target was about to take off...
"Start RM" was the cry from the brigade CP , "Start RM detect the target" shouted the battalion commander ,
Time passed , and the target did not appear. 15 seconds stretched into minutes, "Where's the target?" - yelled
from CP , "Where's the target?" shouted the commander of air defense missile systems , and there, exactly on the same azimuth and on the very same range 95 km at an altitude of 5 km , there was a mark and rapidly spread upwards on the screen.
"There is a target, height 5 .. 7 .. 10 ... 15 .. 18 .... 20" , with every stroke PRV seen the enemy ,
which has ceased to gain altitude and a speed of 1 km per second was rushing to a meeting
PRV . P-18 is also finally found the target , but led her not confident, sometimes not giving a mark
on every turn of the antenna. A PRV is gripped the target in a stranglehold as a well-trained dog
that sees the prey and forgets the humiliations from it's master.
"High altitude , high speed Target - Height 20 , Range 85!" (do not care that does not work MTI) , ..."Height 20 , Range 80, " (to hell with it, with coherent channel) ... "Height 20 , range 75 " (running does not help you go away, and with just one magnetron we 'll get you) . Meanwhile, the SNR in the " wide beam " as a blind kitten , vainly trying to discover what has long been seen by PRV. She (PRV) came to the rescue and gave the commander of the air defense system command: " TSU2 on SNR ." At this point , thank God, not touched by anyone relay selsyns connected PRV and SNR , the azimuth and elevation drive simultaneously turned SNR
in the right direction and then on the indicators pointing officer appeared a mark.
" Target on RS " - a guidance officer gave the operators follow the target.
" Target acquired , height 20 , range 70 " gleefully reported the commander of the air defense system!
"Destroy Target at the entrance to the killing zone" - happily gave the command the CP(HQ) , "The target is on AS "
" Missiles for preparation" , "Loaders to the shelter!." A PRV is at this time continued to accompany the " enemy" tracking its azimuth , despite the crippled EMU , he was ready at any moment to give
new CU-2 and implement the task. "The first - start, the second - start" , the officer just starting
time to press the button , because all of us except the guidance officer jumped out of the cab
and ran to the parapet . Because of the embankment launcher appears a cloud of dust and smoke and fire,
with a dull roar 5YA23 soars to meet the target, almost immediately after her second rushes ,
they already know exactly where to go and what to do , 90 kg of TNT in each of them is not a joke.
As long as we are seeing with delight as landfill in the cloudless sky flying rockets, PRV continues
its work and on it's display two lines appeared and move to meet the target , more than half a minute passes before they meet. "Hooray, detonation! " - we are screeming and embrace each other ,
"Target destroyed, Height 20 , range 40" reported from PRV.
He fulfilled his mission. And we are well noted successful shooting".....
