Very interesting. Thank you. There have been some engineering problems to solve for making them smaller, mainly maintaining enough heat and keeping it localized for enough duration. [If correct, as that was delivered in the ‘80s during an astronomy class lecture. The instructor was a dedicated counter-culture Atheist with a PhD. in a small, Midwestern university that was more feminist than anything else.]
To be fair the F-22 can carry external stores. Hence it may be able to carry that particular bomb.
