if FLIR is not designed for bad weather, so tell me what is the purpose of designing FLIR system if it has no uses for any particular scenario
FLIR is designed for night vision, not for bad weather. I quote.
JDAM is not intended to replace any existing weapon system; rather, it is to provide accurate delivery of general purpose bombs in adverse weather conditions.

UCAV have slow speed often u need to destroy a mobile target with jet. Besides Russia does not have UCAV.
Attack drones are much faster than mobile ground targets like tanks, mobile artillery, pickup trucks. They carry TOW / Hellfire size laser / TV guided air to ground missiles. Attack drones are best for taking out mobile ground targets. Bombers like Su-35, Su-34, Su-24, Su-25 are best for taking out static ground targets like bunkers, tunnels, ammo depots, command centers, power plants, weapons factories. Bombers only need to carry GPS guided bombs using SVP-24 blind bombing system.
Attack drones, recon drones, bombers operate as a network. They have different applications. Sort of like tanks, mobile artillery, mobile air defense having different applications in the same ground column.
Shahed 129 attack drones taking out mobile ground targets in Syria.
Su-35, Su-34, Su-24, Su-25 bombers taking out static ground targets in Syria with GPS coordinates provided by recon drones like Forpost, Orlan-10, Zala 421-16E5.
SVP-24 is not GPS guided bomb its computerized bomb sight. Something that US had in 1970-es.
The US never had GPS in the 1970s. SVP-24 is not a bomb sight. It is blind bombing system which integrates autopilot, GPS, digital ballistic computer, air data sensors into one system to automatically deploy free fall bombs on static ground targets by day or night in any weather condition without having the pilot sight targets visually. It's like M1 Abrams digital ballistic computer / laser rangefinger / crosswind sensor / automatic fire laying machine integrated fire control system except Abrams tank requires the gunner visually sight the target whereas Su-24M2 does not require the gunner to visually sight the target, only having to input the GPS coordinates of the target into the system. The bomb is therefore GPS guided and released by autopilot when the plane's location, height, angle has reached the computerized parameters to ensure a hit on the target.
Dont talk nonsense read about Norden sights.
Norden sight has limited accuracy due to pilot having to sight the target and manually release the bomb. When the crosshair is on the target, the pilot manually releases the bomb. A human has a 0.5 seconds lag to pull the release lever. B-17 flies fast. By the time the bomb has been released, the plane has flown dozens of meters away from the point of impact calculated by the Norden sight's analog computer. SVP-24 controls the autopilot to automatically release to bomb within 0.0001 seconds the plane is over the location calculated by the digital ballistic computer which ensures the bomb does not fall outside of 3 meters away from the target. SVP-24 is way more accurate than Norden sight.
