[X] Frigate engines - you can cram one, maybe two, downscaled S.210 plasma torches on a Large hull, or a single one on a Small. -fuel efficiency is paramount for corvette duties, they have to do the most maneuvering in the fleet. Plus this engine doesnt cost any more, AND its more powerful? Literally the only problem is from a durability standpoint, as there would be less engines on the ship, meaning more likely to be disabled in case of a hit.
[X] Large hull (Cost 7) -I actually had a good long think about this one. If we pick a small hull, it would be FAR more likely to be taken out of a fight by targets on the same weight class (especially since I really want to go with frigate engines). But the contract states that they want an anti-fighter and anti-corvette ship.
If we have a super fast, large hardpoint number corvette we take care of the two issues:
1) The increased speed from the large engines means outmaneuvering and escaping fights is much easier, a bigger deal against corvettes, as simillar sized ships or smaller optimized for other anti corvette actions will have fewer hardpoints, and bigger weapons. This decrease in fireing angle+increase in fire power means that the only way our ship can reach parity with its hull disadvantage (bigger target) is to either increase speed or load up on simillar weapons to overpower the enemies firepower. We are doing a modular ship so the weapons part is somewhat out of our hands. But we CAN make the ship flat out faster, which with the frigate engines is totally possible.
2) the increased amount of weapons hardpoints due to a bigger hull (plus the increased durability) is a great anti-fighter design. Fighters are made for destroying simillar sized craft, so beefing up the ship should counter those weapons. The extra surface area gives more points on the ship to put weapons, meaning a better field of fire than on a small ship. A single fighter pilot will have to knock out more weapons, more engines, and more critical systems to bring the ship down. All the while being shot at by said weapons, and trying to keep up.
In opposition:
[X] Small hull (Cost 5)
[X] FN31s - keeping in theme with the Nova can only help ease logistics. (Cost +2)
The entire point of this plan, is to hope and pray you make it through the fighter screen alright, then slug it out with corvettes normally (with an advantage against larger corvettes).
All for the Same Cost
Hopefully ive made my case good enough.
