Typical Wiki, partly true...

The PU is always elevated higher than the SNR.
(To give the missile enough elevation above the SNR LOS to fall during the first 3sec unguided flight.)

When the SNR is at 0 elevation, it locks down. (black instrument hand)
The PU this time is elevated at 18degree. (red instrument hand)


So the real question, is if the SNR is able to lock on the ship, that is below the SNR LOS?

This is where H<5 comes into the picture, as it actually moves the LOS down 3 degree.
So now the SNR will only lock down at -3 degree. (at 10km range, it is more than 500m below the SNR)

But you answered in more detail so it works!

Quotation from

"22 This opens up another interesting aspect of the much touted �horrors� of the 1972 Christmas bombing of Hanoi. In response to this bombing, the North Vietnamese and their Soviet �advisors� fired 1,242 Soviet made SAMs at the American war planes. Twenty six American planes were hit by SAMs. The other 1,216 SAMs, with warheads in tact, fell back to earth in the Hanoi � Hai Phong area. Has anyone ever heard of, seen or read a report that describes the damage and deaths caused by these self-inflicted missile strikes?"

What about missile self-destruction system used in missiles fired in Vietnam?

All Dvina missiles has self destruction system.
The number of fired missiles are over exaggerated.

Thanks, that's what I though.

Upcoming SA-75M Dvina (SA-2B/F) work in progress pics...

... Digital Elevation, to display ground clutter.


... documentation.

Hpasp, do you know why some radars have 'sound-related' NATO reporting names?
E.g. 'Hawk Screech', etc.

A couple of photos.
To incite the interest =)
Soon will be More.

Ahhh, S-125M Neva, S-300PT Biryusa, and S-75M Volhov

Yes, most of the reporting names are about a properties of these radars.

SA-2
SNR-75M - "Fan Song" is the sound the Weasel Pilots heard in their EW suite.
P-18 - "Spoon Rest" just look on those antenna...

SA-3
SNR-125M - "Low Blow" is about the effective minimum altitude (20m)

SA-4
1S32M - "Pat Hand" is the sound the Weasel Pilots heard in their EW suite.
1S12M - "Long Track" has really long one

SA-5
5N62V - "Square Pair" just take a look on it
P-14 - "Tall King" is really the tallest.

SA-6
1S91 - "Straight Flush" is a poker hand with 5 cards. Here it is the 5 frequency the SURN uses during engagement.

SA-10
30N6 - "Flap Lid" of the MAZ.
76N6 - "Clam Shell" just look at it
36D6 - "Tin Shield" just look at it

and S-25 too

Where???

This is the S-300PT (SA-10A).


Note the clock in the middle...

after S-75 - http://s2.ipicture.ru/uploads/20110905/707I5xhm.jpg

If you compare it to the S-300PS Volhov-M6 (SA-10B), you can see the effort went into the optimization between 1978 and 1983...

Right!


I just need better pictures, to expand the simulator with these systems...

Amidkor, do you have 'daily' access to that museum? Maybe 'better pictures' of S-300 PT are just one step ahead?

I would like to note the difference of the SA-10/20/21 systems.
I feel, that the situation is closer to the time of the SA-2, where three systems were mixed by the west.

Just to make it clear...

SA-75 Dvina - SA-2A with missiles 1D, 11D
SA-75M Dvina - SA-2B/F with missile 11D
S-75 Desna - SA-2C with missile 13D
S-75M Volhov - SA-2E with missiles 20D, 5Ya23

... so:

The first release of the S-300P system was accepted in 1978.
It was the S-300PT Biryusa - SA-10A, and it succeeded the S-25 Berkut - SA-1 ring around Moscow.
It used the V-500K 5V55K (Grumble mod.0) missile, with 47km range utilizing command guidance.



The second release of the S-300P system was accepted in 1983.
It was the S-300PS Volhov-M6 - SA-10B, and it succeeded the S-75M Volhov (SA-2E) and S-125M Neva (SA-3B) units around the Soviet Union.
Its export version was called S-300PMU Volhov-M6 - SA-10B, and it become available from 1988, and was exported into Bulgaria, China, and Slovakia. (GDR)
It used the V-500R 5V55R (Grumble mod.1) missile, with 75km range utilizing seeker aided ground guidance.



The third release of the S-300P system was accepted in 1989.
It was the S-300PM Volhov-M6M - SA-20A, and it succeeded the remaining S-75M Volhov (SA-2E) and S-125M Neva (SA-3B) units around the Soviet Union.
Its export version was called S-300PMU-1 Volhov-M6M - SA-20A, and it become available from 1994, and was exported into China, Greece and Vietnam.
It used the 48N6 (Gargoyle mod.0) missile with 150km range, utilizing seeker aided ground guidance and lofted flight profile.



The fourth release of the S-300P system was accepted in 2004.
It is the S-300PMU-2 Favorit SA-20B, and is available for export only, to satisfy the wannabe customer of the S-400 system, China.
It used the 48N6D (Gargoyle mod.1) missile with 200km range, utilizing seeker aided ground guidance and lofted flight profile.



The fifth release of the S-300P system was accepted in 2007.
It is the S-400 Triumph - SA-21, and it succeeded the S-200 (SA-5) units around the Soviet Union.
It is not available for export.
It uses the 48N6DM (Growler) missile with 250km range, utilizing seeker aided ground guidance and lofted flight profile.

Thanks very much!
Do you happen to have some audio files?

No, i don't have =(
I was there for the first time and short-lived. We were late to the next place = (
I live in Siberia. More than 3,500 kilometers from Moscow =)

Hi, Hpasp!

Congratulations for your good work with the simulator. I have a question, how can I download any data f
rom yandex? It gaves me some .djvu extension on files and I can't read them.
