DCS Reference/Air Defences/Western

Each block describes the system as a whole, the ground units it consists of, the dependencies between these units, and some key performance figures (in most cases data-mined from the game files, but in some instances gathered from in-game tests or 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. These units will have a black circle in the mission editor to signify the range within which they provide ammunition for nearby units.

Note that maximum altitudes can be a bit unreliable 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 — ones with their number in parenthesis — are optional and not necessary for the functioning of the system. Beyond that, the numbers listed only indicate the doctrinal setups and all systems only require one of each mandatory unit to work if the mission designer wants to reduce the overall unit count. 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. In addition, in general, the main radar system is often required to be the first unit in any air defence group. For some of the more advanced systems, it is good practice to make the command post unit the first unit in the group.

Radar-guided

Flakpanzer Gepard

From the 1970's until 2010, this unit was the cornerstone of the air defence of the German Army.

Notes
Has a radar for searching, ranging, and tracking targets. Note that most eastern RWRs do not display this threat. Has no special setup and is instead integrated into armoured or mechanised columns.

Tactics
Not particularly threatening unless you are flying low. Since the 1980's, it is standard procedure to accompany these with Stinger MANPADs, who would take advantage of the Flakpanzer's radar as an early warning system. Note that it still is largely optically guided — do not be fooled by the notch window and think that you can just hover in a helo nearby and plink away without it firing back.

M163 Vulcan Air Defence Systems (VADS)

In service from 1969 to 1993, this AAA gun is comparable to the Shilka. Despite its designation as a AAA gun, in practice it tended to be used more as a ground support weapon, as its range was simply insufficient against air threats.

Notes
Optical sight with radar ranging. Note that most eastern RWRs do not display this threat. Has no special setup and is instead intended to complement the M48 Chaparral, and be integrated into infantry/light mechanised columns.

Tactics
Designed as a complement to, and should be deployed alongside the M48 Chaparral. By itself, it is basically helpless to a competent bombing run. Like with the Gepard, note that it still is largely optically guided. Just because it has a notch window does not mean you can sit in a 0m/s hover nearby and expect it not to shoot you.

MIM-23 Hawk PIP Phase I

First seen in the 1960's, this medium range SARH SAM system was designed to be a more mobile replacement of the MIM-14 Nike Hercules. It was superseded by the Patriot system in the 90's.

The Phase I hawk, as seen in game, is primarily deployed in the hands of both Saudi Arabia and Iran, the latter thanks to US policy misadventures in the 80's.

Notes
The optional components are mostly for decoration (especially the static cargo containers and generators), although the many transport units will provide rearming functionality for the launchers. There exists a Range Only Radar component that 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 additional PCPs. The system is static cannot be driven using Combined Arms.
Available to
Tactics
The typical setup has redundant radars, requiring a few ARMs to take down. Being a SARH, defeating the tracking radar is enough to defeat the missile.

MIM-104 Patriot PAC-2

The PATRIOT, or, Phased Array Tracking Radar to Intercept on Target, for those keeping track of the DoDs contributions to the field of tortured acronyms, is the premiere American long range SAM system. Initially conceived as an anti-aircraft system, the PAC-2 variant depicted in DCS features optimizations which make it efficient at engaging cruise missiles.

Notes
Has self-defence anti-missile capability. The system is static and cannot be driven using Combined Arms.

Tactics
The Patriot system is designed around a battalion echelon, made of up 4-6 platoons. The ICC and the Maintenance Centre are part of the command platoon, which oversees 4-6 "line battery" platoons, each containing one of each radar type, six launchers, and other support units distributed among them. It is a strategically important and expensive system, and as such typically supported by MANPADs. The system is capable of shooting down missiles and aircraft alike with its fully active radar missiles. Considering the number of redundant sensors used within a properly configured battalion, this system would require a sustained barrage of ordinance to bring down. At the same time, note that these larger numbers are quite necessary since each individual component is actually a fair bit less capable than their SA-10 counterparts.
