It was a remarkably prescient document—the first technical description of a workable atomic bomb. The authors were Austrian-British physicist Otto R. Frisch and German-British physicist Rudolf E. Peierls, University of Birmingham. They conceived of this “super-bomb” five-and-a-half years before Hiroshima. They realized that “the most effective reply” to a foe’s possession of such a weapon would be “a counter-threat with a similar bomb”—i.e., deterrence. The memo lent great impetus to US and British nuclear efforts and helped lead to the Manhattan Project.
As the US-led coalition closes the noose on ISIS in
Mosul, Iraq and, later, Raqqa, Syria, deconfliction with Russia’s
separate air campaign is going to be critical, Air Combat Command chief
Gen. Hawk Carlisle told defense writers in Washington, D.C., Friday.
The Iraqi Air Force on Friday conducted its first
strikes inside Syria, hitting ISIS targets in the area of Abu Kamal in
response to that group’s attacks inside Iraq.
The Air Force awarded a $15.6 million contract to ELTA
North America Inc., to deliver 21 “counter-unmanned aerial systems,”
according to a Feb. 21 Pentagon announcement.
