Distances too high for heavy Iranian Fajr rockets-5 launched towards Tel Aviv and maybe even for new M-302, derived from the Chinese weapons WS-1 produced in Syria and apparently turned to Hamas from Iran via Sudan.

The iron dome is created by Israeli companies Elta and Rafael (with a US financial contribution amounted to 275 million dollars) and Tamir interceptor missile uses very quickly and accurately but that costs about 30 thousand dollars per aircraft and is commonly used to destroy rockets worth a few thousand dollars, sometimes even less, as in the case of crude Kassam products in craft workshops in Gaza at a cost of just $ 800 a piece. .
