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?[edit]

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 McWalterTalk 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.
