1 reactor can perfectly handle 1-2 shields. 3 reactors for 1 shield is a bit overkill.
Also, why two 2 HE- missile factories for two launchers?
The main problem why your shields may turn off is because of crew stupidity, not because of lacking reactors. They prioritize loading missiles over powering the shield. Nothing you can do about it unless you add a ton of crew. That's why missiles are better not placed near cannons & laser blasters, which face the enemy to fire.
About the ship, I'll take a better look tomorrow!
