Deep penetration

Head of the US nuclear weapons program, Linton F. Brooks, wants to build a new generation of longer shelf-life bombs, some with special capabilities:

Because their casings were not designed to penetrate earth, "we have no capability against hardened, deeply buried targets." He also described the current stockpile as "unsuited for some specialized missions" caused by post-Cold War situations.

"Today's stockpile may not be the stockpile you want to have 20 years from now," Brooks concluded.

Wonder what some of the "specialized missions" would be? Build 'em and be prepared to use 'em.
