Hypersonic missiles are not cheap. The LRHW that US is putting on land and ships costs $50 million per unit. Its payload is probably a single bomb worth. Its range is 1700 mi. The B-21 costs $500 million. It can carry the same amount of ordinance in one mission as the same cost in hypersonics. The B-21 can carry multiple, cheaper cruise missiles. It can drop the air-breathing hypersonic cruise missiles whenever those are developed. It can loiter over the battlefield dropping bombs as needed. It can come back and do it the next day. It can fly halfway around the world.
