If "Long Track" is a 3D radar, why they're using height-finders?

Maybe for close high altitude targets outside the beam of the aquisition radar? And maybe they need to know the height of targets for distribution of target data to other units so the position and info can be plotted on the plotting board.

Long track will not tell you how high the target is.

"Long Track" means two* radar types, and non of these are 3D in today sense**.

1RL128 P40 - with height finder, used for fighter guidance, and at SAM Brigade level.


1S12 SOC - without height finder, used at KRUG/KUB battalion level.


*easy way to differentiate between these sets from the outside, is to count vertical stiffeners in the antenna.
P40 has 9, while the SOC has 14.
biggrin

**SOC has azimuth, range, and coarse elevation information.
For the SNR with elevation scanning it is enough, for a successful fighter guidance it is not.

Thanks, I did not know this.

But in the video, they have a dedicated PRV heightfinder, probably for the first reason (higher level of command).

On video they are 1S12 SOC and a PRV (-9 or -16)...

Hi! Here're some pictures I took today during the "day of tanks" in Milovice (Czech). Krug is completely dead (except the positioning motors of the radar antenna) so far however I've managed to start up the turbine generator in Kub 2K12 TEL (2P25) so I'll try to take a video once I figure out how to move the platform. And maybe I'll power up the Krug from it so we can lift up the rockets. Obviously both the rockets and the radar parts were legally demilitarized but still all the panels lit will look great and the noise from the fans inside is quite impressive as well. It's really a great piece of a historical machine and I'm more and more amazed while discovering how all its systems woked.

Hi all,

time has passed and the next "day of tanks" at Tankodrom Milovice is coming up. It's going to take place on the last Saturday of the month (29.8.2015) and of course the Krug won't be left in the garage. In case someone was somewhere near Prague, it's an ideal opportunity to take a look. Of course we still don't have a power source so it's only a static display but still it's pretty interesting.
Our efforts are unending though so I'm sure we'll make some more progress in the future. Here're some pictures. I'm happy to say that we're finally getting somewhere with the renovation of this piece of technique. We've been focusing on the 2P24 lately as we'd like to paint it (it's very rusty) and make the elevation and azimuth systems moving. In order to do that we need to repair hydraulic actuators which I'm working on now.









Also I've obtained some documentation lately so in case somebody had a question I'm happy to look the answer up. smile

Hi again. Here're some pictures from an event we recently had and the 2P24 was involved. Also I have a video but it was filmed from the 2P24's commander's seat so you can't actually see much of it in it.:)





Hopefully we'll get some actual work done as spring develops. In summer I'm planning on starting up the gas turbine generator in 1S32.

Hi. So I'm here to report some progress for those who are interested. Just recently we managed to get the hydraulic counterbalance system (on 2P24) working, luckily the whole automatic still works so it wasn't such a big deal in the end. I took a video of operation. Unfortunately the camera recording the actuator wasn't on so I only have pictures. Hopefully I'll take a better video next time. If I feel like unscrewing 20 screws while taking off the covering.... biggrin So here it is. The purpose of the system is to balance the weight of ty rocket by hydraulic pressure (around 12MPa). In the first picture you can see the whole setup (there are two total - one for each rocket). The green big thing at the top is an accumulator, under it there is a hydraulic pump and it's motor and there is an oil tank at the left corner. The second picture shows the piston of the pneumatic accumulator when unpressurized and the last picture when it's pressurized (fully in). The accumulator also serves as the pressure switch (microswitches on the piston itself). And finaly a video of the operator's panel during the operation. The pump takes around 300A of current while near the end of the cycle, that's why only one pump can run at the time. This part of the system doesn't need the AC supply so it works only from batteries (27V starting power source in our case).

Hi again all those interested in the Krug. So as promised, I started up the turbine generator. So far I have to control the valves manually since the control block is missing but I'm in a process of developing it's supplement. Also I managed to power up some instruments inside (yeah, almost in the exact way like it's in the sam sim:)) but unfortunatelly I didn't have time to properly try what's working and what isn't.... Also the antenna block isnt't connected at all. I'll try to bring some of the systems to life when we manage to acquire a diesel 400Hz generator which is quiter and much more fuel efficient... Check out a short video I made! https://youtu.be/XEh6Z8mzdHk

and some pictures here..

Hello Hpasp and community,

In the manual for Krug there are information about missile types: 3M8, 3M8M1, 3M8M2 and 3M8M3. Does variant 3M8M exists too and with what capabilities?
