I say half the number and I'll try to replace the air in their general direction with bullets 
Also, can I ask what new changes? Its been a while and a lot of stuff has happened irl and in other RPs
Well, the newest is my nerfed flying bombs.
Rocket propulsion even the one which uses two stages limits the range to 80km. It's also made slower, around 500MPH. On the other hand my missiles are also smaller because I realized rockets allow me to make them shorter.
Another thing you should know that my flying bombs are of course not on top speed from the beginning. It takes roughly 27-33 seconds and 3.6-4.5 kilometers of continuous acceleration for that to happen.
So if you can get close, you have a better chance intercepting them. They're also have very limited capabilities to correct their course so if you were to get close to them the wind of your approach would be enough to make them nosedive. You also don't need to worry about AA fire in the direction where the rockets are at for obvious reasons.
So yeah, there are means.
Mind it most of these exist for even my current cruise missiles. The real difference is the reduced range due to the rocket design.
But my current cruise missiles are traveling at the breakneck speed of 640MPH instead of the 500MPH of my recently nerfed version. On the other hand they're also bigger targets and may take longer to accelerate to top speed (13.5 kilometers after launch at optimum by my calculations) so perhaps that sits better with you.
It also worth noting that no matter which version I use I won't just spam 300 of them at once. They'd be a sustained assault.
Also like I said jamming the radar beam or preventing my FOs on ground or in the air to spot targets for my airships is a possibility.
