but nothing to say what yet apart from T-90 tanks, and their was talk a while ago about Su-30Sm, only thing the article states is aircraft, artillery systems, and helicopters.

Now a few points about qaher 313 . It seems to be a ground effect stealth aircraft . Using all Iranian components . The reason for downturned wings , can be stability or avoiding vortex . Gaining upto 40 percent lift . With smaller sized engines .so far the concept is good .
However for an aircraft that will fly over water . To attack aircraft carriers at sea .It needs to ideally land on water . Either to wait . Refuel . Or disguise it's IR by cooling engines . In this case . The air intakes need to be on top of plane . Away from spray. The hull needs to be made like a boat shape . And on closing or opening bomb bay doors to be water proof . By rubber edgings and vacuum created inside bomb bay by air pump . To sqeeze rubber edgings . The downturned winglets need to be attached to external fuel tanks . These get used first . And then act as buoyancy . For water landing .
There is no way to hide the launch of aircraft from shore . Even with zero radar return . Jet engine IR visible by sattelite or u2 . At this time aircraft carrier launch F18 . The two planes meet midway between land and sea . F18 being faster and higher move behind qaher 313 . And can fire IR missile . So qaher needs IR decoys . The type that sit on water . But F18 closes in and shoots guns . So qaher needs backward firing IR missiles .
Alternatively Russians can help equip the qaher 313 with more powerful engines . To make it an air superiority dog fighter . It can then take care of carrier F18 . Using cannon or IR / radar guided missiles at all altitudes and speeds .And then proceed to kill the carrier .
Thanks for reply . I understood it . Apart from your use of " mofrei "
I agree that flying low has advantages / disadvantages , in terms of speed etc . But my main concern is about hiding the plane from radars . So hiding the plane , below horizon has obvious advantages . And other radars such as over the horizon radar , may not be as efficient . But for airborne radar , I guess the altitude of plane makes no difference . Only it's radar cross section .
Now about IR signature of engine and plume . The observability depends on :
( 1 ) Altitude of plane . The closer to thin atmosphere . Or high altitude . The more signal pass through to space .
( 2 ) The angle of satellite or spy plane to fighter .
( 3 ) The humidity or cloud cover .
( 4 ) The time of day . Amount of reflected light from the sea .
( 5 ) The size of engine . And if after burner is used .
( 6 ) The temperature of engine . The type of fuel . Wavelength of exhaust gases .
It may be possible by using different fuel type . Engine type . Time of flight . To find a window . Where engine and plume are disguised against background radiation and not enough gets out to high altitude or space .

Lack of parts????? I feel Irans aircraft programmes are just paper planes and no real aviation industry exists. They desperately need new aircraft and nothing seems to be materialising from foreign countries due to sanctions.

There is no point in upgrading an old aircraft to use brand new expensive weapons when old cheap weapons and a delivery system upgrade can be just as good.
Perhaps a case of Iran noticing that cheap old Russian planes with relatively cheap avionics upgrades can match western guided weapons performance, but using cheap dumb old bombs...
