I know it isn't, do not take my words so seriously :-)

Yes we deserve as most information as possible. That's why I am not satisfied with lack of advanced functionality of S-200, which is my favorite system :-)

Not so far in Internet, just couple pages back in this topic...

Quote:
- First white panel of the SAMSIM
The Shilka and the Dvina used the silver hammer finish.
The Volhov, Neva, Vega, KRUG had the blue paint.
All the latest Soviet/Russian SAM systems, and the OSA has the white design.

- Containerized, solid fueled missile with 12s (!!!) preparation time.
- Missile has huge overload capability, evenly in the whole envelope.
- Automatic guidance method selection.
- Automatic missile preparation.
- Automatic missile selection.
- Integrated SOC.
- Amphibious.
- Acquire target on the move, shoot on short stop.
- Dedicated switch against low RCS targets.

It is preparation time :-) Anyways, those 12s was the first idea which went to my mind :-)

But ePap asked for battery life during flight :-)

When you will see OSA-akm you going to love it.
Love with the first sight. smile2

Yes, I know this with S-200 :-)

But I will like Osa for sure :-)

No no no.Please try harder. wave

Also another issue pop up.
What is that 12 sec preparation time ? How do we realize that as operators?
For what reason exists ? mycomputer

I know it isn't :-) I would guess somewhere around order of 30s, given the flight speed and maximum distance.

Preparation time is the time from "turning the missile on" till the moment it can be launched. It is time needed to start up gyros and all electronics and other systems.

1. No no no.

2. Partly correct.This preparation take place only when we have a firing sequence ?

I do not know with OSA, but I suppose it will be the same as with other SAM systems when you turn missiles on and in the mean time you do other things (no target can be acquired at all).

If the preparation was part of the firing sequence, you would lose 12s in the case of OSA and given the fact it is a short range system, you could be dead or the target could be away (not even talking about longer times with other SAMs).

All the above are correct.
It is not necessary to have lock on target and to loose these 12 sec in the firing sequence.
As soon as you get EW for enemy plains in you area you can by the use of a switch to activate/prepare missiles and when
You think what is the proper time you lock and fire.All the above is tactics.

The most important issue behind the preparation of the missile is not that this is a part of the sequence of the fire BUT the
exercise (Russians call it trenasor ) of magnetron of the missile.

What about the battery?

Yes, I guessed about 30s, but that was not correct, so I must admit I do not know. Maybe battery has a greater capacity to have enough capacity in cold weather and so, so under "normal" conditions it could last about 60s, but it is really a wild geuss :-)

Ok my friend.
Here it is the answer.
There is no battery at all, on the missile!!! winkngrin

So does it have some pneumatic generator? It was a good joke :-)

Man,it's not a combat ! mycomputer
More information about the system.
A hard core sim is under construction .
We need well trained operators...


It would be very beneficial for everybody, if you could start a series describing the OSA antenna systems, instruments, operation (target acquisition/tracking/engagement in steps) in longer posts...

Yes it does!!! thumbsup
It has a metallic squib with nitrogen under extrem pressure .When the fire button is pressed a pyrotechnic divice energizes
This squib and the released nitrogen under pressure moves a pneumatic generator and it is produced
the necessary electric power.

This squib is just behind the Radom of the nose of the missile with the blue wirings at

Basically the table is correct.
Live firings in NAMFI ,where STIR tracking radars track OSA-akm missiles revealed bigger average velocities from 16sec to 23 sec. !!!
Never lower of 500m/sec at the very last 23rd sec.That gave us the certainty of 1km extra range (very useful especially during
maneuvering targets ).
