Navy “assets” also took part in the attack, which the unit, based in Tampa, Fla., said was launched against “various advanced conventional weapons used to target U.S.and international military and civilian vessels navigating international waters.”Attacking so-called hardened buried sites generally requires the use of specially built bombs that have much thicker steel cases and contain a smaller amount of explosives than similarly sized general-purpose bombs.

The heavy casings of such “bunker buster” bombs allows the munition to stay intact as it punches through soil, rock or concrete before detonating.The B-2 is the only warplane that can carry the largest of this class of weapon in the Pentagon’s inventory: A 30,000-pound...
