INDUCTION OF LY–80 LOMADS IN PAKISTAN ARMY AIR DEFENCE: LEAP TOWARDS RANGE AND LETHALITY

[hussain0216]

Why didn't we induct LY-80 B with 70 KM range?? Or we plans to induct it

The latest ones inducted are 70km are they not, only the earlier ones were 40km someone correct me if im wrong

 

[YeBeWarned]

@gambit @Penguin Thank you so much brothers for such wonderful replies

hmmm Strange

 

[Penguin]

Mr. Penguin explained it well enough in no. 11 .

I like the philosophical angle.

 

[AZADPAKISTAN2009]

Well I doubt Pakistan or China will dislcose the real ranges for detection
However general rule of thumb for such systems is around 100km but it could be alot more

March 2015 National military parade Pakistan includes FM 90 low level SAM system.

March 2017 National military parade included LY-80 low/medium level SAM.

I wonder (more like hope!) what the March 2019 parade might include..............if it's a trend in the SAM capability I certainly welcome it!!!!

LY-80 MR-SAM and FD-2000 LR-SAM were evaluated by Pakistan in 2013. Given the financial constraints, the purchase of FD-2000 was postponed.

Three LY-80 systems were ordered for US$ 599 million and 8 IBIS-150 radars for US$ 40 million.

Five more LY-80 systems are expected to be purchased.

Main contractor CPMIEC will integrate LY-80 with FM-90 SR-SAM and Swiss AA guns.

I will add some additional thoughts...and @Starlord

Every missile have the capability to re-target.

https://en.wikipedia.org/wiki/Infrared_homing

Early infrared homing missile often were misled by the sun. This is the clue that every missile MUST be able to re-target.

Whatever the sensor -- radar, IR, or camera -- we cannot guarantee that the sensor will have %100 target view from launch to impact or near proximity.

So it begs the question of: What do we do in the event that the sensor lost sight of the target, whether that sight is radar, IR, or camera ? We incorporate a re-targeting process.

Take infrared, for example...

At its basic idea, IR is about contrasts (plural) of infrared radiation between multiple bodies or sources.

http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/images/apeside_ir.jpg

For the above example, only humans recognize that the cluster of IR sources resembles that of an ape, but for the IR sensor and its processes, the sensor sees only contrasting IR sources.

For the IR homing missile, we design the system so that it is attracted to the highest intensity IR source among sources. If somehow the sensor lost that contrast and somehow that contrast reoccurred, we design the system to re-acquire that highest IR source. Unfortunately, for the early IR homing missile, the sun simply overwhelmed any other IR sources, so that re-targeting process steered the missile towards the highest intensity source -- the sun.

Same idea for chaff against radar homing missile. The chaff cloud creates the highest intensity of reflected radar signals so the missile's re-targeting process steered the missile towards the chaff cloud. Only humans sees the chaff cloud. For the missile's radar, it sees a large voltage spike.

The human brain is equally vulnerable to the re-targeting process. We say that the human vision is attracted the motion, but that is not true. It is our brain that is 'wired' to be attracted to motion. That is why a truck being larger will attract our attention more than a car. We have just performed that re-targeting process.

The original question seemed to be about if it is possible for a SAM to re-target via an outside command ? The issue is not about engineering because of course we can. But now, in addition to the missile being aware of its target, there must be another observer of the entire battlefield, readied to make quick judgement and command the missile to perform that re-targeting process. That observer can be a guy on the ground with a binoc or a team of radar operators in an AWACS. From this point on, the missile's sophistication and technical complexity increases, as well as the financial burden to build it.

To date, we have opted to let the missile make its own re-targeting decisions based upon the programming that we give it. The result is the great differences in performance among competing arms manufacturers. One company may know how to distinguish chaff from aircraft while the competing company do not. This is about warfare, so manufacturers do not give guarantees.

That explain everything ... damn how can i not think of that,despite seeing so many hollywood movies where they always show hot Hero fool the heat seeking missiles with some sort of decoy flares , or fire .. but i agree with @Penguin to, i like the philosophical touch

As per MoDP:

3 LY-80 systems ($226 m) and 8 IBIS-150 radars ($40 m) were ordered in 2013-2014.

6 LY-80 systems ($373 m) were ordered in 2014-2015.

The LY80s inducted are most certainly the 'B' version since our armed forces have a track record of always going for the best depending on availability, whether it's F16 block 52 plus or Yuan class subs with AIP. It's just that we like to keep it a surprise until the final moment . The element of surprise can always make the difference.

Pakistan's are the 40-km version. This was announced at the March 23rd Parade.

Strange though, why would they go for a version with shorter range if they have a better one available. We are lagging behind in air defence. We desperately need long range high altitude systems.

That was the version available when they signed the dotted line in 2013-2014.

Ohh but then there's a second batch signed for in 2015. Also, defence systems are usually advertised about quite late in contrast with their availability to ally nations. Anyhow, hope we get those FD2000s or something similiar in the not so distant future.

3 FU and 6 FU. Each system has 2-4 FU (according to ALIT website).

Each system has 1 IBIS-150 radar.
