    The laser designator is for illuminating targets for laser guided munitions. Helina is not laser guided so it is not needed and actually a risk to the pilot if used on anything with a laser warning receiver (LWR). The range finder is a far less powerful laser, undetectable by LWR. The designator might come in handy if supporting air strikes using LGBs but the pilot is putting himself at risk.

    Laser guided ATGM is now losing its sheen. We are moving to fire and forget missiles and Satellite navigation guided bombs.

    Why would anyone want to use laser now? Isn't it simply better to acquire the satellite positioning to guide even simpler bombs? By the way, why would a light helicopter like LCH be used to carry guided bombs?

    The advantage of laser guidance is cost and ability to hit moving targets. Sat guided bombs need INS gyros along with its positioning receiver which raises cost but is all weather. Within visual range IR guided munitions with lock on capability like Helina are best as they are all weather and can hit moving targets. The seekers are still more expensive than simple laser reticles. I was not refering to LGBs for LCH but the Elbit link posted earlier that had a laser designator, it can be used to designate LGBs dropped by LCA or other fighters.

    I don't know where you heard it's loosing sheen, it's doing good and far better sensitive sensor research are going on, A lot of my friends would be pissed of if they heard your comment it's their bread and butter.

    The only problem with them is someone needs to be there to guide the missile to it's target, MMW is doing good but laser sensor is not going anywhere.

    Try hitting a moving target with GPS guided bombs, GPS guided can be jammed much easily then Laser, but now there are quite a few anti jammers kits are also available.

    Is it me or LCH has a very silent rotary wash? The engine spool noise is more than those massive baldes going arround... But yes when it hovers over head it has that signature low Durubb-durubb

    A more knowledgeable member might be able to better answer your query as my knowledge on helicopters is rather limited but to note is the fact that this video is of a very early LCH prototype.
    A better means of evaluating your theory is to analyze later models as the LCH design has evolved considerably since the model in the video.
    If I am not mistaken the displayed model is that of TD1 while TD4 is currently undergoing field trials.
