Radar, IR and datalink systems optimised for fighting other aircraft may struggle to track smaller, faster hypersonic signatures consistently. That overload or mismatch of sensors can degrade coordinated defence and missile cueing among many F-16s.

Hypersonic flight (many times the speed of sound) compresses engagement timelines. At those velocities, defenders have far less time to detect, track and react, meaning incoming threats can arrive before a coordinated response is possible.

An object striking at hypersonic speeds carries enormous kinetic energy. Even without detonations, impacts or collisions at those speeds could cause catastrophic damage compared with subsonic or transonic weapons typically carried by legacy fighters.

Hypersonic platforms can operate across regimes (very high altitude, near-space or extreme low-level high-speed runs) that traditional air-defence doctrines for aircraft like the F-16 were not primarily designed to counter, complicating interception.

Classical fighter tactics, turning, dogfighting, close-in missile manoeuvres, rely on giving pilots time to position and employ weapons. Hypersonic encounters can be so brief that those tactics become irrelevant, favouring strike and shoot-and-leave profiles.

If the hypersonic platform carries very long-reach strike options or kinetic effects, it can engage from beyond effective response ranges and depart the battle space before interceptors can effectively mass and respond.

High-tempo, high-speed threats place exceptional demands on an air force’s C2 (command and control). When a single contact forces rapid, dispersed reactions across dozens of fighters, timing mismatches and confused priorities can lead to inefficient responses and higher losses.
