Unconfirmed reports from military sources claiming that Iran managed to recover multiple American bombs from the sites across the country, including the GBU-57 bunker buster
The bombs are sent to IRGC engineering units for reverse engineering and some say that Araghchi sent one to Russia during his visit there (highly unlikely, because he traveled from Islamabad to St. Petersburg).
Anyway, this is a very interesting development and judging by previous successful reverse engineering jobs by #IRGC, I bet we will see Iranian missiles with bunker buster war heads in a not so distant future.
This will be a major setback for both US and Israel.

Pentagon inadvertently proves that the bomb was not capable of “obliterating” a facility buried 80 metres underground by showing video that shows bomb destroying a cavern just 10 metres underground. (If that)
(The stated maximum depth for the GBU57 is 60 metres)

In medium-strength rock, things looked far different. The #GBU57 could only go around 7.9 meters (about 25 feet) beneath the earth — far short of the 60 meters claimed by the infographics.
This may be an important part of the reason the weapon failed to destroy its target — if indeed the bombs did #fail as the #DIA assessment claims.

"It depends enormously on the kind of rock," says Raymond Jeanloz, a professor at the University of California, Berkeley & one of the original authors of the 2005 National Academies Study on earth penetrators.
When I ran the calculations, using a key equation from that study, Geoff Brumfiel found out that the #GBU57 could go up to 80 meters (262 feet) underground if it was dropped in silty clay.

Why the #US’ giant bunker-busting bombs may have failed to reach their #nuclear targets in #Iran
They depicted America's #BunkerBuster bomb, the #MassiveOrdnancePenetrator, or #GBU57. It was being dropped from high above the Earth by a #B2 Spirit bomber. Then, the graphics showed it plowing a narrow channel deep beneath the ground — around 60 meters, or 200 feet — & erupting in an illustrated explosion.

Physics Equation of the day:
𝐷=0.00178⋅𝑆⋅𝑁⋅(𝑊/𝐴)^0.7⋅(𝑉−100)
Penetration equation for soil, rock and concrete targets. The Young/Sandia equations based on empirical work by Sandia National Laboratories. https://www.osti.gov/biblio/562498
GBU-57 has mass 13,600 kg,
length 6.2 m, diameter 0.8 m. Only 20% of the bomb’s total weight is the explosive filler. The case is Eglin steel.S = Young S-number. I get 0.66 for good quality hematite with 155 MPa compressive strength. 0.9 is default for concrete. 2 - 5 for dense,dry, cemented sand.
N = 0.8 Nose performance coefficient (eyeballed from the picture of GBU-57 and then used eq. 3.7 in the paper).
W = 29000 lbs, penetrator weight
W/A = 39 psi weight to area ratio,
V = 2250 fps (Mach 2) impact velocity, I picked high end estimate.
Reported 60 meter _penetration_ into concrete from The Economist and RUSI seems too high.
What I get wrong?
