Defense Field Equipment

[Titan*]

So Discovery have like 5 equipment. Cloak-Disruptor-JD-Matrix-Survey i don't know if there are more
How about a defense field equipment?

So Defense Field will work like POB Shield(not rreally), it will covers the ship inside of the shield and it will have 1K or 2K or 3K Field Range
Defense Field will have duration time 60 or 120 seconds and ships inside the Shield will take %75 less damage from hostile ships
Also it will affect hostile ships if they get inside the Defense Field

I think only carriers should have access to this equipment so they can support the friendly ships instead of attacking a battleship

If possible snubs shouldnt be affected by it because a snub with %5 hp can run into the defense field and not die for some time

or

Second idea;

A Defense Field Generator that deflects incoming torpedoes-missiles for 60 seconds

Good idea or not? Discuss.
