Hypersonic speed does not remove the targeting problem

Are hypersonic missiles a dead end, and how do they hit maneuvering ships at long range?

They will matter, but mass production and guidance remain difficult; even a very fast weapon must predict or update a moving ship's position during several minutes of flight.

Hypersonic weapons would enter service gradually rather than dominate immediately, because technical problems and economies of scale still matter. Long range complicates the promise of speed. Over hundreds or thousands of miles, even a short flight gives a ship time to alter course. The weapon therefore depends on a working sensor and targeting chain rather than speed alone.
