This doesn’t really mean that much, What Israel wants and NEEDS is the GBU-28, a 5000# deep penetrating weapon that can go though 20 ft of concrete, or 150 feet of earth. THIS is the only weapon that can take out the deeply buried Nuclear sites.
The Achilles heel of these deep underground installations is that they always require ground level access points. Blow them to smithereens and it really doesn’t matter if the actual deep underground installation survives or not. It is realistic to expect that we—and the Israelis—know where at least some of these access points are. I suspect that they are hidden in hospitals, schools, apartment complexes and mosques. One approach to the task, according to this simple retired soldier, is for Israel to bomb the access points we know of. Then, progressively, destroy others as they are found. These bombs can be dropped from such an altitude as to allow the Israelis to give fair warning when they bomb an access point hidden in civilian facilities. The aircraft will be high enough to minimize Iranian gound to air threats. In any case, I’m sure the Israelis will prep the battlefield—i.e. locate and destroy as much Irani capability before the bombers do their job. The bombers will then be accompanied by fighters that will run interference for them and destroy whatever additional irani capability. At the same the Israelis will be employing their formidible electronic warefare capability against the Iranis. Those idiots—even forewarned—will be helpless in the face of the Israeli onslaught. The Syrians have the same Russian stuff as the Irani’s. The Israelis creamed their nuclear facilities. They got into Syria, destroyed the target and got out without losing a single aircraft. One hopes there will be a special delivery package addressed to the the good Achjamenahod (Irani president, premier or whatever—I don’t know correct spelling of his name) on the target list.
