Is it only using one missile?
Tbh I was hoping for missile with longer range and altitude...
It is sufficient for now. The altitude is above the service ceiling of any aircraft that can attack Iran. And the range is good enough to space them out about 100 km apart. I would alternate them with the Talaash. And protect them with Herz-9, Raad, 2k12, Pantsir and Tor. With some air defense artillery too. You can't have just one air defense system protecting your assets in a local region. As proven in Syria. 200 km is a minimally good range to set up a vast network of air defenses to stop any cruise missile or air attack. Layers of defenses is what is needed. Even having spotters with man-portable air defense SAM along the coast in a wide chain of coastal air/sea defenses.
Just having one BAVAR 373 to protect a region and have a few cruise missiles pass the defense means a lost Bavar 373 and a hole in your air defense. Man portable SAMs should be mass produced and are cheap. The goal is to protect the airspace of the vital long range SAMs, so nothing ever passes them.
An attack happens at night so light house bright lights like in the Berlin air defenses during wwii would be needed for coastal defense to spot the cruise missiles. The lights turned on when the radar detects cruise missiles over the sea.
Layers upon layers, upon layers of air defense is needed. And if they can't dominate the sky, they can't invade Iran.
Single air defenses with hit ratios of .6 or .8 will never cut it. Enough of an air attack will overwhelm the single solitary air defense and will knock out Iran's air defenses. Iran needs to overwhelm the attack with high and low tech defenses to get every last plane and cruise missile out of commission.
Iran would also need Bavars further inland to protect from ballistic missiles attacking cities and military assets. Again with short range air defenses to protect the long range air defenses.
Iran should produce as many modern up-to-date Iranian versions of ZSU-23-4 Shilkas as possible too. High tech to low tech, missiles to artillery. If stealth cruise missiles are ever invented, artillery would be an added required tool. Where the missiles would be picked up on radar and difficult to hit with defense missiles. Overwhelming the sky with bullets aimed at the target knocks out any stealth missile. Also useful against UAV and 6th gen swarms. Air artillery is designed to not run out of bullets and fire all day and all night.
