WIP Day Part 3 - SAMday

As I explained with the Rapier FSC yesterday all the SAMs we're making are going to rely on the FCSS for their advanced functionality. I was asked yesterday what other SAMs we're making. So today we're going to show you some more SAM systems.

Each of our SAMs are modular. Each unit performs a task as it does in the real world: search Radars, FCRs and Launchers. What started with the Rapier FSC expanded to support other addon sets.

We've also begun to incorporate "tie-ins" between the FCSS and our aircraft. When we started looking at fire control and missile spamming we didn't really plan to design and build a modular system with addons that interlock together but it seems we have now. I guess you could say we've been guilty of allowing "feature creep" but trust me the creeping has been worth it. At least form my point of view. Anyway I digress, we'll cover the FCSS in more detail in a few days.

Rapier FS'B'

The Rapier Field Standard "B" is the 2nd generation of the Rapier. (The FSC is the 3rd) that first saw service in the 1982 Falklands War. They we're combat proven according to the manufacturer form the first day of the landings. The reality is somewhat different. The Rapier did manage to down several Argentine aircraft but not without first having to overcome some serious problems.

The first problem was serviceability. The Rapier Launchers were never designed for sea voyages. The constant motion and banging around played havoc with the electronics. Not to mention the damp sea air causing corrosion. On the first few days of the landings (i think) only one Rapier was actually operational and then only in optical mode! The rest were non functional due to the rough crossing.

You see the FSB had 2 modes of operation: An autonomous Radar system that tracked the aircraft and guided the missile in and a semi manual Optical system operated from a remote 'turret'.

The reason the radar was not working was less a mechanical issue and more of a lack of foresight. In the bay where the landings took place there were several large warships providing protection for the landing craft. Each of these was busily jamming every radio and radar frequency possible effectively blinding the Rapier. Later versions addressed this with a much improved radar system and an upgraded missile.

For the purposes of ArmA we chose the FSB as a “Res” SAM unit.  The idea was to provide each side with a comparable air defence system.  Its modern enough to still be a credible threat in the modern world and is still in service with several nations.  Unlike the FSC the FSB is a two tier system with the option of manual control via the Optical Tracker (not shown).

  • DN-181 Blindfire Fire Control Radar (FCR)
  • Launcher with 4x Missiles

As with the FSC the FSB has some redundancy built in.  If the FCR is destroyed the Launcher can function on its own albeit at a reduced range.

The MIM-23 Improved HAWK

The HAWK System has been around since 1959 and has evolved into many different varients.Its stil in service with over 20 nations world wide although quite a few of these are actively seeking replacments. The most likely of these is the NASAMS system offered by Kongsberg. The appeal of this appears to be that there is a conversion kit available that converts the old HAWK launchers to uses the new NASAMS/AMRAAM missiles therefore reducing the const of conversion.

Chosen as a RES and OPFOR weapon system the I-HAWK was intended to be a medium range SAM to compliment the Short range ManPADS and SHORt range Air Defence (SHORAD) systems providing a layered defence network. As withthe other FCSS enabled addons it has 3 components.

  • Launcher with 3x Missiles (as shown)
  • MPQ-64 Sentinel Radar
  • AN/TPS-75 Search Radar

Now the I-HAWk really only needs the Sentinal Radar to function properly but its usually part of a wider Radar network so we've chosen to pair it with the AN/TPS-75 Search Radar. Its fair to assume that any nation able to buy and support the I-HAWK will also have a resonable Search Radar to go with it.

 

MIM-72 Chaparral

Again another 'old' system, chosen for its age and accessability given that most operators have already, or are planning to retire it soon. it makes it a perfect lowcost standalone SAM solution for any side. Given the strength of Sahrani's local forces makes the MIM-72 a logical Air Defence solution.

This is unusual in our SAM projects inthat it really doesnt utilise the FCSS's capabilities by default. The MIM-72 is a Infra Red system using the older AIM-9D sidewinder so isnt linked into any radars. However there is nothing preventing it being added to a FCSS enabled air defence group so that it won't missile spam and waste its ammo.

SA-6 "GAINFUL"/2K12 "Kub" System

Next to the FCSS and the Harriers I think theis is probably the most request/asked about addon we have. its also the most inactive. A lot people may complain about that but until recently we've not had the time to make it work how we wanted it to. This may take a bit of explaining so bear with me:

As with most SAM system the SA-6 (sorry but I'm more comfortable with NATO designations) requires several radars and supprt vehicles to make it function properly. We're not going to make the full range but we are going to focus on the main three:

  • 2K12 Launcher with 3x missiles
  • 1S91 "STRAIGHT FLUSH" Radar unit
  • P-40 "LONG TRACK" Search Radar.

The launcher is pretty much complete, the model was finished for OFP it just needs bringing up to ArmA standard with re-mapping and RVMATs etc. The "STRAIGHT FLUSH" is very much WIP. Getting decent reference for it proved very hard but i have enough to make a reasonable simulation. The "LONG TRACK" on the other hand, well I'll be honest i haven't even started it. You see in the real world, technically the SA-6 doesn't need it to operate. The 1S91 radar is actually two radars, both the Search and Fire Control system mounted on the one chassis. the "LONG TRACK" just provides a greater detection range for the battery so its been steadily driven to the end of the work queue.

The main reason the SA-6 has been long neglected is that its actually quite hard to make it behave realistically in game. The real SA-6 batteries are sent out to a site and dig in. They cant fire on the move. ArmA's default condition for a vehicle in combat is to move around so we have to resort to some scripted solutions. The "STRAIGHT FLUSH" is another problem in that to get it to move the radar arrays must be folded away and stored. Being a perfectionist sort i wanted to have it all animate away smoothly. its perfectly possiible but obviously this take time to develop and integrate. So while there are simpler setups to use as test beds for the FCSS we shelved the SA-6.

I do intend to dust it off and get it in game at some point i just cant say when. For an initial release they may end up as a static objects alot depends on time and what ArmA2 brings.

Thats all for today. More tomorrow.

Really awesome !
I was never noticed before this that such a functional AA system was on development for ArmA.
Looks now that the AAM threat will no more understimated during ArmA combined (air to ground, CAS, airborne assault etc...) operations.
Most part of third world countries has in their inventory such AAM systems...

You guys do great models, I was hoping you guys might do a SLAMRAAM Model...
