Hear is an update on the Lightning fighter and some background:
The class was designed during the Klingon War by an engineer who was fascinated by the fighters of WW II, but stayed on the drawing board as it was thought to be somewhat of a novelty. But as the war progressed Starfleet Command put out a request for a new fighter to escort landing hoppers in battles where transporters could not be used due to dampening fields. Due to the urgent need for a fighter and the Lightning's other wise sound design, it was dusted off and put straight into production. It did not take long to realize the ship was all so useful as an interceptor and an assault fighter due to its relatively heavy armament and shielding. The novelty had become an extremely effective fighter so much that it is still in use today by many starbases and in planetary defence forces.
