Some basic concepts about Nova II - as I "conceived" it.
http://efni.org/nova2.htm
Note: these concepts are unrelated to the game, they are pertinent to the concept I tried to design in my site.
1)Operational role - Battleship - defensive/battle line oriented. Firepower, armour and survivability have paramount relevance. Its role is to make up for the center of a battleline, the "anvil" in an "anvil and hammer" fleet battle.
2)Layout - Straight plates, simple hull layout to ease production. Rugged, heavily armoured and with excellent internal compartimentation and structural integrity: it can take punishment and continue to fight and kill.
3)Mobility and propulsion - Powerful reactors, auxiliary reactor for weapon feeding - this ship will never have power shortages issues. The weapon feeding reactors are militarised industrial designs in order to keep down the cost.
The main engines allow average acceleration, the ship is not as fast as a Warlock but it is very maneuverable (short, fat hull, relatively low inertia moment, powerful maneuvre thrusters) - a relevant trait for short range combat.
The Nova II DOES HAVE jump engines - needed for strategic redeployment without being tied to jumpgates.
The endurance is not great: it is not a patrol/strategic assault unit, or a battlecruiser, the inhabitability is acceptable but not aimed at long cruises. The propellant reservoir is tailored for a medium endurance cruise/waiting time in a system, and a "battle time" high acceleration, high fuel consumption series of manoeuvres.
Esssentially, this ship is designed to:
a) travel from its base to a system where is expected a battle, line up, fight the battle.
b) jump into a yet started battle. Fight.

Armament. (see for reference
http://efni.org/weapon.htm)
Long range weapons:
-
two nose mounted G.O.D. beam cannons Mk IX, smaller and shorter and cheaper than the ones of a Warlock,
http://efni.org/weapon.htm#GOD
-
forward firing missile tubes (the missile silos are in the forward "hammer"),
-
four "long lance" pulsed lasers (the ones on the tips of the wings):
http://efni.org/weapon.htm#QSL2T - these lasers, developed from the Hyach spinal laser technology, have not the explosive effects of the GOD cannons, but are well ranged, accurate, and they have an exceptional piercing power: they punch holes through the enemy hulls.
This "long range package" is conceived to attack and saturate an incoming enemy formation, or to soften an enmy formation while the Nova 2 closes in.
Fighter complement: smaller than the one of the Warlocks
Medium and short range weapons:
- Battery of fusion fed plasma cannons - (the large flat barrel cannons) - or "fusion pulse cannons"
http://efni.org/weapon.htm#M381 - They fire plasma bolts, the fact that they are fusion boosted (they have their own fusion reactor in the breech) means that, while being short ranged as the usual plasma weapons, their effect on a target is devastating: do you remember the "green pulses of doom" fired by the Babylon 5 pulse weapons against the Omega in "no surrender, no retreat"? - think to plasma bolts MUCH more powerful, and you can visualize the effects of such a weapon - intercept it, or die.
- couple of plasma mortar placed in the bow hammer - the same oval weapons in the chin of the Nova and Omega hammer
http://efni.org/weapon.htm#Mjolnir. Think to them as a plasma carronade...
Railguns: http://efni.org/weapon.htm#PESANTE - the same stuff used on the Warlock. Devastating at short range.
Defensive weapons: the same side turrets of the Omega, http://efni.org/weapon.htm#WRK 1005 but more of them and with better firearcs, a very good anti-fighter and interceptor capability.
All the main weapons of the "Nova 2" can fire in the forward arc, a broadside is about 50% of the total firepower (except for the spinal GOD cannons), the rear facing firepower is four fusion plasma bolters (of 12), two railgun turrets (of 4) two pulse lasers (of 4) and (more or less) an half of the smaller "interceptor" turrets.
Sensors:
as all the "post civil war/drakh era" "EFNI-Verse" ships, even the "nova 2" - still to be renamed

- do have, behind the standard radar and scanners suite, the EGAD Sensor suite - see
http://efni.org/Styx.htm
- Essentially, this includes a set of passive gravitic sensors that "feel" the gravitic propulsion systems "local warpings", as they can track the "warping" of a soon to be opened jump point. These sensors are not extremely accurate, but are sensitive and long ranged.
a medium range advanced LIDAR - something like a phased array radar, but operating in the optical spectrum, nearly unjammable
and each weapon has its own multispectrum optical tracker, with stereoscopic visual sensor and rangefinder - even in this case, we can think to a medium-short range system nearly unjammable.
All these sensors were conceived in an "anti-minbari" environment, so they are specifically:
- Based upon gravity or optical spectrum (so where the Minbari stealth system does not work)
- Passive in nature (except for the LIDAR), so extremely difficult to jam.
- Very accurate at short and medium range. The gravitic sensor act as a "long range early warning" - an anti ambush device.
Essentially, the Improved sensor suite was developed since late 2240 in order to:
1) Search and detect for Minbari ships through their carachteristic gravitic signature. (gravimetric sensors)
2) Allow a stealth-proof positive tracking and target lock on (opitical technologies)
but it was really operational only since the "civil war" period.

For what is worth, I hope these concepts can help.
