Nothing... useless unit. If you love useless units so much, then stick to rockets.

They are the best unit in the game! You can produce them in 1h 45m in a lv 1 secret lab and they completely obliterate economies! Also a good way to get rid of enemy airfields if you dont have rockets to spare!

That means you can produce 14 per day per city!

Do not seek for answers you are not ready to hear...

Their only use is to unlock missiles and kill weak units at the start. They are just a stop gap to missiles.

The are relatively cheap and fast to make. Use them to take out targets that you can't reach with artillery or air power. Good in the first several days of a campaign when units are limited.

in a very rare circumstance they can be deadly.

In my war with Poland in the RP, I killed 60,000 Poles with flying bombs and rockets, this took about 30 minutes. In the previous 24 hours of patrolling bombers I killed 60,000 Poles as well; the flying bombs were about 50 times more effective over time. Now imagine that effect outside of an RP, where you dont have rules.

I love Flying Bombs like how i love Light Tanks, fast and eventually get the job done. Both are easily spamable, take little time to produce and do good damage.

Interceptors and tactical bombers are in love with you.

good for damaging lvl 1 airfields and annoying other players

They can be used to swarm units, this is what I would mainly use them for.

when two adjoining nations face stalemate at war.

ex : me (Borneo) vs Jay (Sumatra) (BMfox community game) both have same amount of cruisers and neither wanted to risk them in battle, so that I came up with idea of shutdown his industries with flying bomb,I can use queue features so when I woke up I have dozen of flying bomb at ready.

they have fair amount of damage, 3 of them can kill 2 lv.1 infantry.
8 of them can make opponent cities at high risk of revolting.

spoiler : I won the war.

in conclusion, flying bomb is good if used in swarms

Rockets are better.

no doubt.

They look cool, act cool, can't be shot, bigger, better, far stronger.

Rockets bigger and better.

Agree but the question is about Flying bomb, not rocket
