The B-52 bomber is a period 104 double-barrelled glider gun. It uses two blockers, two molds, two blocks and two tubs to hassle a B-heptomino as a shuttle, and thus emits one glider every 52 generations. It was found by Noam Elkies on March 21, 1996, except that Elkies used two more blockers in place of the two molds. This smaller version was found by David Bell later the same month.
Its name comes from the war plane in the U.S. Air Force.
On June 11, 2019, Jeremy Tan found a 31-glider synthesis for this gun.[1]
