You don't need more. That is plenty of ship for PvE. I hang here a lot in the ship subforum, offering my hot takes on various builds. And I'm always leaning toward making the ships lighter and faster, the things -- along with jump range -- that I prioritize. Very rarely, or maybe never, do I see other players flying ships that are as light as mine are. But yours is! Your Krait is actually one ton lighter than my combat Krait (I have three Krait IIs)
This is mine
Poison Whiskey Krait II -- Combat Sweeper / Scout Sniper
So you can see our ships are quite similar. And interestingly, you got it so light while still using 30 tons of armor (or 30 tonnes of armour haha).
Not much I would suggest changing, but the things that jump out at me are
-- Sensors. By all means use As if that's what you prefer. They do have some advantage. For me though I prefer Ds, Lighter, yes, and less power draw. G3 long-range mod is the sweetspot for me. Plenty of range in those.
-- Shield thermal resist. I highly recommend finding a way to increase this. This is key to shield 'elasticity', the ability for the ship to shrug off hits and prevent shield collapse. The shields on my build were in storage and aren't quite what I would have done from scratch for this ship. But in practice they are more than enough to survive CNB and RES combat. I can't recall the last time I had my shields shot away.
Weapons -- I'm not keen on mixing lasers as you've done. My suggestion woul be to replace each of the lasers with multicannons, and put two large beams on it, as my Krait has. All MCs are overcharged, with corrosive on the centerline large, and autoloader on the outboard mediums. Doing this would give you better shield stripping ability without compromising your hull damage much. But there are many valid combinations, just spitballin' suggestions.
-- Optionals. I am not a fan of the supercruise and docking assist. But I don't begrudge anyone if they find them helpful or useful. Dropping these would free two slots. Perhaps you could even replace those with HD HRPs to gain integrity and drop the armor. Heavy-duty stock alloys are still pretty good and you'd then drop that 30 tons, making it even lighter! You can see our two ships have nearly identical integrity, but only one has armor, so it's posible to get your ship to the same level of protection without any heavy armor at all.
I think my Krait also has better utitlity, with collector limpets and a bigger scoop while matching your jump. So I think there's room for some adjustment in your optional slot choices should you decide to revisit these.
But overall I really like what you've done. Your Krait has great speed and jump, just my sort of ship. If you had come here with a very different build, my suggestions would have ended up with the ship you already built haha. Nice work Rietz
And welcome to the boards
