If i am not wrong but GIDS is being made of ex KRL firms which under KRL were under foriegn sanctions and under GIDS they are not
Easy...Must have something to do with technical aspects. As chinese are using laser proximity fuze in their PL-9 missiles as well as in the latest Pl-5E series missiles which is already in service with PAF and used on JF-17s. A very technical guy may answer that why is one system used on one missile and another system on others.

Little help Sir.
The missile is fitted with a cryogenic liquid nitrogen gas-cooled IR seeker capable of +/-40 degree off boresight angles.
The surface material could be doped paint to reduce reflectivity and that doping could be deliberate or accidental, meaning the paint was never developed to counter laser distancing sensor but turned out to be highly effective anyway. The designers of the missile that uses the laser must try to take the diverse reflectivity factor into account.Abstract
The reflective characteristics of several materials have been examined in an effort to develop a 10.6-microm reflectivity standard for field measurements with laser radars. Measurements on twelve different target materials showed that many materials have components of diffuse reflectivity, specular reflectivity, and retroreflectivity. For each material examined, both the effective Lambertian reflectivity and the beam depolarization were determined. It was also found that because of the strong retroreflection component present with many materials, the practice of estimating the effective diffuse reflectivity from measurements of total reflectivity could lead to erroneous reflectivity values for laser radar systems. One of the preferred reference targets found for 10.6-microm field measurements was canvas tarpaulin.
Beamriding missiles generally have kinetic kills as the goal and the laser beam provide the 'pointer' or guide towards the target. In an air-air situation, it is not (yet) possible to have a third party provide constant laser illumination of the target for the missile to latch on to the beam. The PL-9's laser system seems to be of the latter design -- use of target reflections.A laser-guided missile consists of six basic sections: the photo sensor (laser seeker) with optical filter, control circuitry, guidance section, fuse, propulsion section, and the warhead with fuse (Fig. 1). Two design topologies are used for laser-guided missiles. In the “beam rider” approach, the missile’s photo sensor detects light emanating from the launch site, such as a ground station or aircraft. The laser beam carries directional data, which the control section interprets to adjust the missile’s steering fins accordingly. In the alternative approach, a missile’s on-board sensors make use of laser-light reflections from a target. The launch vessel beams a laser onto a target and launches the missile, which measures the distance between itself and the target via the on-board sensors. Control circuitry is used to adjust the missile’s navigation equipment for accurate delivery of the payload.

It is an operational aircraft sourced for testing.
so this pretty much confirms that even the BLK-I will be fitted with IFR probes at some stage. Thanks!

A quick question: does that mean the prototype we saw was for block-I only or the same fixed IFR would be used for block-II as well. A constantly visible (fixed) IFT contributes to RCS and as we are improving block-II on avionics, weight-carrying capacity etc, one may think it would also improve on RCS.
What is your learning on that?
... ... there is not enough room for a retrectable IFR, no light/medium fighter can accommodate it hence the fixed IFR.
I think Pakistan is lobbying this time. At least some political maturity is shown.Why would these rich GCC states be keen?

kia baat hai ap ki aqal e saleem kiWell your thinking doesn't matters as i am well aware that American LGUs / LGBs are very much integrated with F-7P / PGs, and for many years now. China doesn't makes such designed LGU kits nor Pakistan is making Laser Guidance kits. AWC recently started to make Chinese ToT FT series glided bomb kits with INS/Satellite navigation, which you just saw in that Takbir series bomb kits.

when did usa give LGUs / LGBs to pakistan
bro usa never allows us to modified or even to install our equipments on their aircraftsI think he meant the JDAM kits for 1000/2000lb bombs, which are an improvement over laser guided ordnance.
GPS-INS type navigation seems to have an advantage as the aircraft can release these at a stand-off distance, rather than waiting for laser guidance from the aircraft, which can be hindered during bad weather.
