This video goes into some information about Iranian drones but there are bigger questions. There are basically only three ways to get past Air Defense systems. Saturation, avoidance, or rendering useless before the encounter. (jamming, sabotage, destruction). Now, you might have read that last sentence and glanced over the two most important words. Those two words were 'get past'. If you can not make the range, you are not in the game.

DUBAI -- Russia and Iran are working on a new shipping corridor that cuts Europe and its sanctions out of the picture, and are looking to partner with India, which has kept its distance from the Western-led isolation campaign against the two countries.
International North–South Transport Corridor
The International North–South Transport Corridor (INSTC) is a 7,200-km (4500 mile) long[1] multi-mode network of ship, rail, and road route for moving freight between India, Iran, Azerbaijan, Russia, Central Asia and Europe. The route primarily involves moving freight from India, Iran, Azerbaijan and the Russian Federation via ship, rail and road.[2] The objective of the corridor is to increase trade connectivity between major cities such as Mumbai, Moscow, Tehran, Baku, Bandar Abbas, Astrakhan, Bandar Anzali, etc.[3] Dry runs of two routes were conducted in 2014, the first was Mumbai to Baku via Bandar Abbas and the second was Mumbai to Astrakhan via Bandar Abbas, Tehran and Bandar Anzali. The objective of the study was to identify and address key bottlenecks.[4][5] The results showed transport costs were reduced by "$2,500 per 15 tons of cargo".[5] Other routes under consideration include via Kazakhstan and Turkmenistan.
