| the bunker buster, if used, will almost certainly be nuclear. estimated tonnage: 300 kt |

| MOP is a conventional weapon, 30,000 lbs. Only the B-2 is rated to carry it. https://en.wikipedia.org/wiki/GBU-57A/B_MOP |

| ▲ | xnx 18 hours ago | parent [-] | | Genuinely surprised that Israel couldn't push one out of their c-130s | | |
| ▲ | algorithmsRcool 16 hours ago | parent | next [-] | | The kinetics matter here. The B2 flies much higher than the C-130 which would aid the GBU-57 MOP (almost certainly used here) in it's ability to penetrate to maximum depth. 80% of the 15 ton weight of that bomb is just heavy metal to give it maximum energy as it borrows into the ground. Also, each B2 can carry 2 MOPs making it a better platform than a C-130, and that isn't even taking the stealth of the platform into account | | |
| ▲ | xnx 15 hours ago | parent [-] | | > Also, each B2 can carry 2 MOPs Wow. That is amazing. 60,000 lbs. combined. |

| ▲ | 1659447091 17 hours ago | parent | prev | next [-] | | Don't think the C-130s can fly high enough with a single 30,000lb bomb. The graphic at bbc site show it would be dropped from about 12km (~40,000 ft) in order to gain the speed needed to drive it some 60m underground. | | |
| ▲ | ahazred8ta 15 hours ago | parent [-] | | From 40,000 feet, the bomb would take ~ 50 seconds to fall and would impact at mach 1.5. |

| ▲ | CyanLite2 16 hours ago | parent | prev | next [-] | | Various sources are saying 6 to 12 of these bombs were used. So, you'd need a lot of C-130s and those planes are too slow to NOT get shot down. | |
| ▲ | giantg2 17 hours ago | parent | prev | next [-] | | Do they even have access to this variant? I thought they had access to the older ones that weren't as advanced. | | |
| ▲ | dingaling 14 hours ago | parent | next [-] | | The MOP isn't particularly 'advanced', it's basically refined version of the Korean-vintage Tarzon guided earthquake bombs. It's just too heavy for most military aircraft to carry. The IDF has the F-15I which has a centerline hard point rated for 5,000lb load. That's immense for a fighter but a magnitude too low for the MOP. There are a variety of smaller US penetrating bombs that the F-15 can handle, but they don't have the mass and structure to penetrate as deeply. | |

| those of you hating on this comment, the conventional weapons could not possibly work, the facility is too deep |
| |
| ▲ | tempestn 15 hours ago | parent [-] | | Even after everyone corrected you with information on the specific ordinance used, you're doubling down? | | |
| ▲ | tehjoker 14 hours ago | parent [-] | | they might be right, but that's why the attack failed and why there's a risk what I said might still come true i was listening to Al Jazeera, one of the DC flaks they interviewed gave an upper estimate of the facility depth as 1000 ft. The conventional device can go to something like 60m or 200 ft. 6 devices were dropped, they would have to have everything, including geology with repeated strikes on the same point, be perfect to get past 1000 feet, and then they probably would not destroy the whole facility. As far as I know, they don't even have a good map of the layout. hence, the only real option is a nuclear weapon. this is absolutely being considered inside the pentagon. our government is psychotic. a 1 kt nuclear weapon (laughably small, hiroshima was 15 kt) is 73x more powerful than a 30,000 lb bomb. they would be like, well, it's an underground explosion! The world will forgive us. it's so crafty and smart to use a nuke to stop a nuke (that doesn't exist). https://x.com/ArmsControlWonk/status/1935741526191100181 "The effectiveness of GBU-57s has been a topic of deep contention at the Pentagon since the start of Trump’s term, according to two defense officials who were briefed that perhaps only a tactical nuclear weapon could be capable of destroying Fordow because of how deeply it is located." https://www.theguardian.com/world/2025/jun/19/trump-caution-... | | |
| ▲ | tempestn an hour ago | parent [-] | | Ok, I see the logic, but nuclear weapon use is the brightest red line in the world. If there's anything a government wouldn't be forgiven for, it's that. I can't imagine how the calculus for the US would work out in favor given the risk. (Of course that assumes rationality, which one could certainly argue is lacking, but even still.) Also 1000ft is an upper estimate, right? It's certainly possible the MOPs were sufficient. |
