The first operational anti-aircraft missile system, the Nike Ajax, was launched by the United States in 1953.
A new guided missile system was needed which could destroy entire formations of high-altitude, high-speed aircraft at a greater ranges with a single missile. After extensive studies, it was determined that this new system would require the use of a nuclear warhead in a new missile having greater range and speed than the Nike-Ajax missile.
Fast-forward to today and Raytheon PR announces an anti-swarm missile system, the Block 3 Coyote, has “aced” a military test.
Block 3 utilizes a non-kinetic warhead to neutralize enemy drones, reducing potential collateral damage.
To be fair, Raytheon distinguishes the Block 3 as a reusable model, unlike the Block 2.
Unlike its expendable counterpart, the non-kinetic variant can be recovered, refurbished and reused without leaving the battlefield.
It’s interesting to differentiate it in the PR as non-kinetic, given how it probably has a kinetic effect (e.g. waves of power destroying or disabling electronics).
Also it’s not really fair to say a kinetic platform can’t be reusable, since that’s a design decision (e.g. explosive warhead could be launched like planes do with missiles).
I suspect someone demanded a lower-cost profile on the Coyote and marketing came up with the language to make a false distinction from the earlier design.
