Same article from a web site that doesn't suck.
http://amarillo.com/news/latest-news/2016-09-08/report-pantex-dire-need-upgradesProbably some truth to it, though many of the facilities are being upgraded. I didn't notice in the article anything about the new building. If I have it right, they are building a new outside-the-fence administration building. Except Pantex isn't building it, Texas Tech is, and Pantex will lease it from them.
Typical government, they won't spend a few million to build, but they'll pay 100s of millions over the lifetime of the lease.
