Revision as of 22:42, 1 June 2020

This resource is for players and mission designers to know the capabilities of and set up fully-featured and functional SAM groups using the many various units available under the “Air defence” vehicle category in the DCS mission editor.

Each block describes the system as a whole, the ground units it consists of, the dependencies between these units, and some very rough performance figures (in-game and wiki-based). In addition, optional units and decorative static objects that would complement the system and make them closer to the real setup are listed, even if these units generally serve no added function. The only exception is ammunition-providing M818 and Ural trucks that effectively give nearby units (within 200m) infinite ammunition capacity.

Many systems include some sort of commander unit. The functionality these units is, at best, mythical. No official explanation has ever been offered, and community answers consist of a never-ending string of unsupported claims ranging from increasing detection range, to providing faster reloads or increased rate of fire, to data-linking (…but to what, or for what purpose, no-one knows). They are not necessary to create a working anti-air group, but it is possible that some obscure efficiency parameter will be degraded by leaving them out.

Note that maximum altitudes, in particular, can be a bit vague due to the interaction between maximum sensor elevation, sensor range, and missile flight capabilities. While the maximum altitude may seem sufficient on some systems, it is often a lot lower in practice because there is a rather narrow band between where the missile still has energy enough to climb, and where the (usually) radar is still able to track a target. For maximum skylord murderness, make sure the altitude capabilities are ridiculously above where the target is expected to fly.

Italicised units are optional and not necessary for the functioning of the system. Units (mainly decorative) that can be found outside the Air Defence category have their category indicated in parentheses, as do decorations that only exist as static objects.

Basic Concepts

  • All SAM components must be in the same group in the Mission Editor in order to function.
  • All SAMs have limited ammunition.
  • Placement of an Ammunition truck (such as the Ural-375) of any kind nearby a launcher will allow it to reload.
  • SAM components should generally be placed close to each other. However, many SAMs (especially later radar based SAMS) are able to spread units as far as 25nm from the command post, enabling dispersed configurations.

Eastern systems

Radar-guided

S-75_Dvina S-75M1 Divina / SA-2 Guideline

Typical Layout of an SA 2 (minus static or nonfunctional objects). Includes Shilkas and an Igla team to cover against low approaches.

The SA-2 is a Soviet Radar guided medium range high altitude SAM system developed in 1957, but continues to see use to this day. The missiles are given remote commands from a ground operator, effectively making them Semi-Active Radar Homing.

ME Notes

The Rapier Blindfire Tracker is a good visual representation of the height-finding radar, but is commonly unavailable to countries that possess the SA-2 and would probably interfere with detection mechanics if mixed in — a better solution is to add it as a Static Ground Vehicle object.

The system is static and cannot be driven using Combined Arms. For further information, see Technical Report APA-TR-2009-0702.

Tactics

Soviet doctrinal placements of units are in a flower pattern, with sensors/logistics units at the center and launchers arranged an a circle around them spaced no more than a few hundred feet apart. However, this is a very easy arrangement to spot from the air, so guerrilla forces throughout history have been known to use other arrangements for the sake of concealment. Since reuse of sites is a common practice, these rules are frequently applied to newer SAM batteries, as well.

One of the easier systems to evade, the tracking radar is easily fooled via notching and chaff bursts of at minimum 4 per second. Missiles have no guidance of their own: defeat the track radar to defeat the missile. Missiles guidance is fairly stupid, and can be dragged into the ground. It is also completely unable to track targets at sub 1,000 ft altitudes, leaving it vulnerable to low runs. As a result, sites should also include short range anti-air able to engage at low altitudes, such as AAA guns and MANPADS.

Neva/Pechora / SA-3 Goa

The SA-3 is a Soviet Radar guided Short Range SAM system developed in 1961 as a complement to the SA-2. Missiles are guided by remote command, but DCS treats them as SARHs.

Acquisition time ?
Notes
  • Launchers should be placed within 70m of the central guidance area
  • The transporters, containers, and radio relay van should be positioned 100m away from the central guidance area (but no farther away than 200m from any launcher so as to provide reloads); the other units should be part of the central guidance area.

The Rapier Blindfire Tracker is a good visual representation of the height-finding radar, but is commonly unavailable to countries that possess the SA-3 and would probably interfere with detection mechanics if mixed in — a better solution is to add it as a Static Ground Vehicle object.

The system is static and cannot be directly driven using Combined Arms. For further information, see Technical Report APA-TR-2009-0602.

Tactics

Despite its short range, the missiles are rather maneuverable, and harder to shake off with fancy pilot shit. The system is also somewhat more resistant to ECM than its predecessors, but is still rendered toothless once the track radar is defeated. It can also track at lower altitudes than its predecessors.

2K12 Kub / SA-6 Gainful

The SA-6 is a Soviet Mobile Medium range SAM developed in 1958 intended to cover ground forces from aerial attack.

Notes

P-19 radar optionally added to extend search range.

The system is mobile but cannot be directly driven using Combined Arms. For further information, see Technical Report APA-TR-2009-0701.

Tactics

This system was designed to be a mobile point defense system to protect ground forces from aerial attack, as such it can move with them and set up within 15 minutes. It is also employed as static point defense around important installations.

Missiles are initially guided by remote command, becoming SARH in the terminal phase. The "Straight Flush" is equipped with both a tracking radar and an optical sight, making it a real life possibility to launch and guide until the terminal phase, minimizing RWR warning time and SEAD vulnerability. The possibility of a DCS SA-6 AI of any skill level or scripted behavior doing this is unconfirmed.

9K33 Osa / SA-8 Gecko

Developed in 1971, this short range low altitude SAM is highly mobile and makes for a dangerous escort for ground forces or complement to other defenses.

Notes

Addition of “Dog Ear” radar can extend detection range, though it may be undesirable for emissions control

The system is mobile and can be directly driven using Combined Arms. For further information, see Technical Report APA-TR-2009-0704.

Available to
Russia, but only with historical units turned off Abkhazia, but only with historical units turned off Algeria, but only with historical units turned off Belarus, but only with historical units turned off Georgia, but only with historical units turned off Kazakhstan, but only with historical units turned off Greece, but only with historical units turned off South Ossetia, but only with historical units turned off Ukraine, but only with historical units turned off USAF Aggressors, but only with historical units turned off
Tactics

Each TELAR has a radar and optical sight for searching, ranging, and tracking targets as well as for missile guidance. Can launch and track 2 missiles at a time, possibly without RWR warning if optical targeting was used.

Can lock incoming missiles but only has limited self-defence anti-missile capability in this manner. Human controllers and scripters might consider to instead just turn off the radar and scoot out of the way in event of a perceived SEAD attack. It can track while on the move, but must stop in order to fire. Shoot and scoot tactics can make this unit a very elusive target for SEAD aircraft: units adopting this tactic would be better engaged by a maverick or high altitude laser guided bomb.

Notes
All firing units have the same offensive capabilities. The difference is mostly cosmetic, other than that the Ural-375 variants can be driven around, whereas the rest are static emplacements. All can be directly controlled using Combined Arms.

Has no special setup and is integrated into infantry or light mechanised columns, or used as static defences for fixed installations. If combined with a Sborka command vehicle, each vehicle coordinates 6 sections of ZU-23:s.

Notes
A basic Tunguska battery consists of:
  • 6× Tunguska

To expand on its capabilities and provide infinite ammunition, add 1× “Dog Ear” radar and 3× transporter/transloaders. For further decoration, add 3× repair/test/assembly stations, 1× repair/test station, and 1× mobile workshop.

Has a radar for searching, ranging, and tracking targets; missiles are optically guided and do not require a lock-on. Missiles can only be defeated through manoeuvring.

The system is mobile and can be directly driven using Combined Arms. For further information, see Technical Report APA-TR-2009-0703.

Early-warning / GCI systems

These units can be turned into ground-based GCI radars by assigning the advanced waypoint actions:

  • Start Enroute Task > EWR
  • Perform Command > Set Callsign
  • Perform Command > Set Frequency

They are all static units and cannot be driven using Combined Arms, but offer detection capabilities that tie into the more realistic simulation modes of LotATC 4 DCS. The editor detection ring displays an artificial limit of how far detection scripting will report a target; actual ranges for the EWR task are much longer.[3]

For further decoration, add 8× Structures/GeneratorF and 12× Cargos/Container static objects. Add 3× Unarmed M818 trucks to provide reloads and to approximate the M501 Loading Tractors.

The ROR is a fall-back system to help with ranging in a high-ECM environment. It is not simulated or present in DCS. Similarly, the AFCC and LSC are distributed systems for redundancy should the command post be eliminated. The effect of these can be approximated by adding 3 additional PCP:s.

The system is static cannot be driven using Combined Arms.

Notes
Has a radar for searching, ranging, and tracking targets as well as for missile guidance.

Has no special setup and is instead integrated into armoured or mechanised columns.

In Combined Arms, reloading and rearming the ADS is very prone to breakdowns, and missiles very rarely track outside of minimum range. The EWR cannot be driven. While nominally supported, the Roland is for all intents and purpose not compatible with or suitable for CA direct control.
