Here is an update released by the DoD on 8 Feb 2011 via http://www.defense.gov/Contracts from U.S. Department of Defense Office of the Assistant Secretary of Defense (Public Affairs): Boeing Company of St Louis, Mo., was awarded a contract modification not-to-exceed $15,150,000 for additional Massive Ordnance Penetrator Integration to include flight test support, three (3) additional test assets, an alternative/modified fuse design and sixteen (16) fuses. At this time $5,984,488 has been obligated. AAC/EBDK/EBDJ – MOP Tiger Team at Eglin Air Force base, Fla. is the contracting activity.

May be a mistake?

Hello, on wp.fr, after the translation of this article some people noticed something that looks impossible. It's this part: Penetration:

200 ft (61 m) of 5,000 psi (34 MPa) reinforced concrete

26 ft (7.9 m) of 10,000 psi (69 MPa) reinforced concrete

According to this figures, the harder the concrete is, the easier it is to penetrate it.

I don't think you're reading this right. Regardless of the accuracy of the data i.e. is the 200 ft datum the actual number, the two values simply state that the penetration is greater with concrete of lower comppressive strength. And btw, five thousand psi concrete is not particularly hard. Clearly when doubling the concrete's comppressive strength, the penetration is greatly reduced. — Preceding unsigned comment added by 71.183.233.12 (talk) 22:12, 15 April 2017 (UTC)

Though I know that a material can be hard BUT fragile, as the glass for example, I think it's a mistake (not 200 ft but 20 ft).

I was a civil engineer, for me it's unbelievable to penetrate 200 ft of this REINFORCED concrete. REINFORCED means with a lot of steel bars. Thank you for taking time to read this. Joël Deshaies. --85.170.172.37 (talk) 10:09, 13 September 2011 (UTC)

These numbers come, in part, from Global Security, which comments on them "these number seem suspiciously high and may in fact be first in feet, not meters". -- Finlay McWalterჷTalk 15:00, 18 November 2011 (UTC)

The way I read this, it can penetrate 61 m of concrete rated to withstand 34 MPa of pressure, and only 7.9 m of concrete rated for 69 MPa of pressure. That is, assuming my understanding about grading of concrete is correct. So a doubling of compression strength reduces penetration by a factor of ten (roughly), which does not seem too insane.

Title Change for Consistency

I recommend that the title of this page be changed to be in line with the format of other pages of US/Western Explosive Ordnance.

For instance - GBU-43/B MOAB, and GBU-53/B StormBreaker etc. and also so for MOP Disambiguation list, it would be listed.

The Massive Ordnance Penetrator, has a real designation of GBU-57A/B.

I suggest that the page name be changed to 'GBU-57A/B MOP', or 'GBU-57A/B Massive Ordnance Penetrator (MOP)' with a listing under KarmaKangaroo (talk) 07:51, 21 December 2022 (UTC)

Requested move 21 December 2022

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion.

The result of the move request was: page moved. Andrewa (talk) 00:22, 6 January 2023 (UTC)

Weight

It says this bomb weighs 12,000Kg (or 14,000Kg, depending on where in the article you look), and has a warhead of 2,500Kg.

What makes up the rest of the weight, that isn't the warhead? And what's the attraction of having to lift 14,000Kg into the air, to make a 2,000Kg explosion?

Is there some mistake? MrDemeanour (talk) 19:05, 30 June 2024 (UTC)

Inconsistent conversion from 30,000 lbs to kgs

'graph 1 says: "30,000-pound (14,000 kg)",

while 'graph 2 says: "30,000-pound (13,600 kg)".

The right conversion is 30,000 lbs = 13,607 kg, so 'graph SB fixed.
