The Giraffe Agile Multiple Beam radar is not the an enhanced version of the old Giraffe radar, but a brand new radar system, it is a True Three Dimensional Search Radar which features an active phased array antenna with full 3-D capability.

It is like comparing Leo 1 with Leo 2 MBT, similar name but 2 very different beast.

Theater defense or not is immaterial as long as your SAM radar is facing or going to face new standoff threats like KH-31P ARM. As long as your SAMs radar triggers the Su-30 MKMs RWR, it will pinpoint the radars location and upload the parameters to the KH-31P, then you can pretty sure whats next, the KH-31Pthen will be launched following the radiation from the Radar. However, if the radar happened to be phase arrayed, in search mode, it can use less beam power to detect the su30 MKM without triggering the fighters RWR. Even if the su30MKMs RWR being triggered, the KH-31P will find it hard to lock on the frequency agile main beam emitted from the ground Phase array radar. Thus, the survival chance of the phase array radar is much improved over old era mechanical scanning radars. If enemy suppressed your radar, whats going to do with missiles? Upgrading a SAM system, 1st thing has to upgrade the radar.

Should consider Israeli SPYDER system (Derby + Python 5).

However, any similarities to predecessors like the Giraffe 75 end with the name, explains Per J妑bur, Ericsson Microwave Systems' sales director for market operations. Its radar is completely different from previous versions, featuring new algorithms and equipment that put it a generation ahead of other Giraffe models. "We threw everything away except the cabin and the mast," J妑bur says

A GPMG attched next to the Igla.The Igla platform version seems defferent from
NDP one.

It's still a relatively shorter range radar compared to the Russian radars that run the S-300 systems though. Conceded on the phased array stuff.

My 2 cents

Should gradually overhaul I-hawk, a 3G Airforce got no reason to rely on 2G legacy SAM as its main ground based air defense. Replacing it ideally and realistically with true 3G SAMs like PAC-3

Fingolfin_Noldor SG

The US might not be willing, though the Vietnamese already have the S-300.

That is the CIS 50HMG , not the GPMG

Regarding ARMs,

i'm pretty sure we have

1) jammers
2) emergency shut down
3) Decoys.

Anyone with a right frame of mind in preserving our troops, (given the way that RSAF is built upon) should have those things.

I dont really understand what's the uniqueness of the Spyder/Derby System. Is it that it has a Phased array radar?

How's that compared to a Hawk/rapier system that we have now? The range is about the same i think?

Lionnoisy:
There's nothing special of the mech igla. It's a Coaxial. Why you paste a picture of a 50 cal tripod?

Regarding newage SAMs,

they -are very costly- both to have and to maintain/upgrade. I rather we spend money on beamable jammers to reduce capabilities of enemy fighter jets. So they have to come closer to try and get a better bite or shoot earlier and lower the chance of success.

I believe that we dont have LR sams is also because it overlaps the envelop being held now by our F-5s which is more or less for defense, that can be quite dangerous.

Dont forget, F5s engagement range is amraam and that's decent.

With our intergrated AA network, i can safely assume, our sams can be fired -earlier- to engage the planes further due to guidance from C2.

gary1910 SG

Becos it is meant to support short range SAM.

lionnoisy SG

Note GPMG.

The platform seems different from old one.

From what i can tell:

They shifted the coaxial from lower to the top left. Which is now inline with our 25mm - m113s(which is on the right though)

Probably it's due to better alignment/ accuracy at longer ranges.

The mech igla is using a modified 25mm m113 turret which can rotate 360 degrees.

The Hawk is different because it's an upgraded varient.

sgf SG

Took us forever to bring in decent MBTs. Maybe it'll be another decade or 3 before we get new SAMs. Mr. Green

unless there's a desperate need for us to purchase it. Mr. Green

I was thinking MINDEF planners sees the RSN air defence system as a mobile integrated air defence system that can be linked to the RSAF. Remember back in Asia Aerospace exhibition, ST displayed this frigate that can carry 64 VLS on it. Who noes, we might be getting some Navalised SAM eg ASTER-30 or SM-2 missiles. Since the vessels are out at sea, lesser chances the enemy can pinpoint the location. Unlike air-bases on SG. These bases can be easy hit by enemy artillery.

Cold launch - or launch without a lock. After some agarlogy, illuminate the target to achieve a lock. That way the target have no time to do evasive action.

maciam SPYDER SAM lor. Laughing

Instead the Jammer can kill an ARM, its the prey of the latter, remember ARM is passive guided and it  homes On Jammer

Radar being shot down is equal to your Radar being suppressed. And switch on again takes time and target re-acquisition is extremely slow for the old era mechanical scanning radar if compared to phase arrayed ones. If your SAMs are tasked to protect more important asserts like Airport, then once your radar is shot down. The hostile fighter jets will overcome your SAM post and deliver the fire-N-forget long ranger guided A2G missiles. Here, lower tier or point air defense systems wont work on the strikes like su30MK which fly fast and shoot at a height.

ARM decoy is essential a radar without receiver & signal processing. It never comes cheap, and because the ARM will always shoot at the emitter which illuminated its launching plane previously, so lure the ARM away from the old era radar by the decoy is not easy or just impossible if the radar never shots down at 1st place.

Fingolfin_Noldor SG

Are there systems where the Radar is defended by a point defence system like the Phalanx or a rolling airframe system?

coolant SG

Well, realistically speaking, did RSAF acquire such close in defense system at 1st place? In spite you keep adding in modern close in defense systems to protect legacy main systems, why not upgrade all in once? Close-in system is not a sure kill of incoming supersonic missile. Even if your close in system intercepts it successfully, the multiple fragments from the close-in explosive also will probably hit your sensitive electronic devices.
