EMP missile (weapon)

The EMP missile was a quick-fix solution to the problem of the limited availability of EMP weapons at the time of the war with the aliens. It essentially consisted of either conventional or cruise missiles with EMP-detonation charges strapped or attached to the outer warhead. It would likely constitute as a class 6 weapon.

Design
During this timeline, the military (likely the US military) had not done sufficient research into EMP based weapons and had very few practical systems. After demonstrating the effectiveness of the EMP gun, Josh suggested a way around the issue of the lack of EMP-capable missiles by suggesting an EMP charge or similar (a device any country could make) be strapped or attached to the outer hull of any given warhead on a conventional missile.

Although the weight would affect aerodynamics preventing a precise hit, the aim of the unit would be to simply get the EMP charge close enough to a given class 9 spacecraft and detonate it (the missile didn't need to make contact). By using a flurry of EMP-attached missiles with a general swarm vector, it would be possible to detonate the group near-simultaneously and thus form an EMP net. The fact the EMP units disabled the now-defunct missile warheads was an added bonus.

Capabilities
The EMP missle had very limited capabilities and was a last-ditch effort. Different missiles and countries had different results given different styles of implementing the same solution, although overall the missiles were initially successful in downing a number of class 9 spacecraft, once the aliens had become familiar with the tactics involved with small groups of missiles, they disabled and avoided the missiles (as opposed to ignoring them thinking they were a non-threat).

Due to the ease of disabling by the aliens, much larger numbers of missiles were used to overwhelm their capabilities by giving them too many missiles to disable, however EMP missile stocks quickly ran out and the last ditch broad nuclear EMP option had to be deployed.

Current iteration
In the present iteration (532) there have been numerous attempts to develop EMP technology recently, including the lightning gun, the EMP missile (or drone, depending). It's unclear if these are leaks from iteration 232.
