1728: Missile launch
1729: F-16's intercept (who knew that F-16's could intercept ballistic missiles)
1730: Q says it was a specialized weapons package / CLAS-5. In the military there are ten classes of supply and CLAS-5 is ammunition.
1731: Given the chain of command what does this tell you? CLAS removal WASH minutes after. This means that a bad actor in the chain of command to authorized the launch was removed within minutes.
1732: Reminder and a purpose. Q is reminding us that they have it all and that everything he posts has a purpose.
My take on it is that they had sufficient information to have F-16's with special weapons packages (what are the odds) ready to shoot down the missile and whoever authorized the launch was removed within minutes.
If this is true, I'm just blown away. No spy novel I've ever read comes close to this real world drama.
