Looks very cool, usually poptart looking ships don't strike my fancy but this worked out very alright. Probably the best ~500k ship on the Dock for people looking for one of those. Against the average or worse player you'd likely do alright in pretty much any situation.

Against anyone else? Not impressed.
According to you it's meant to hold down and destroy capital ships, not necessarily brawl with them, but it didn't do either with any level of success. It doesn't survive long enough to "overwhelm and kill". It's not fast enough to be remarkable and it doesn't utilise it's OD in a way that would be helpful. Meagre stop weapons and a modest jump inhibitor can hold it in place without much difficulty. The lack of shields and armor means it's incredibly vulnerable to almost any level of hostility directed at it. The shield regen is par for the course, but alpha will - and as you can see, did - turn it inside out. Point defense against missiles is barely pushing noticeable - reduce the size of your turrets, maybe dock them off of the hull, and reduce your entity count. It hurts servers when stuff undocks.
As mentioned before, the lack of any sort of aux armoring means a single hit can be catastrophic. At least put a layer of advanced or blast doors around each group.
Firepower is lackluster at best. Too much pilot armament in sizes that would have just been better as turrets, especially in a ship this size. Even with its fairly good turn speed for such a high mass it's not turning fast enough to catch people, and the lack of proper turret armament hinders it further.
That said, it's still probably the best large ship on the Dock as of today (July 1st, 2017). To "elevate it above other combat vessels of its weight" it needs significant improvements, namely;
1) Armor your auxes. Doesn't matter how, it'll survive much longer with any level of armoring.
2) Give it a docked hull and a bigger JD, or settle and give it more shield cap.
3) Move firepower from pilot control to turrets, and improve collisions in turrets. Self power them.
4) Manual stop system. Dunno why an interceptor of any sort wouldn't have this.
5) Bigger scanner. 18,000 isn't sufficient to unjam someone who wants to stay that way.
6) Kill a swarm computer. It's going to hurt you in fleet operations (which would be necessary for a ship built like this) more than help you. Save one for anti-drone duty, reduce overall size, and give it a tertiary.
7) Use saved internal space for more shield cap or armor.
Everyone seems to have a problem with its lack of a shield buffer even though its not a front-line tanker, again see the description to alleviate your confusion. The majority of PVP ship uploads are cancerous as fuck. I dare you to do better.
