It is mainly used to Intercept and destroy ships (because it's just good at it lol).
Uses 2 Railguns mounted on the bottom, they are 150mm, travel at 20000m/s and fire simultaneusly, sink ships in one hit and is very destructive if landed on an target aircraft.
It has 2 CIWS-like Miniguns that can shoot down Missiles(and other things in front of you, just in case.
Also has Vectored Jet engines (AG1) that increase Maneuverability but sadly makes the Lightning unstable.
Pull down VTOL to use Airbrakes to Lower your speed significantly, you can use this to get more time to aim the Railguns or force the enemy to overshoot (if the enemy is faster than 500mph) or just to fly slower.
This thing is very Armored against Gunfire and can shoot down missiles, but it has 2 weakpoints: The Cockpit and the Engines.
