Now, before the next fleet I should note that the Uni:T mod also comes with a second race, called Uni:T Viral. I’ve not designed a fleet from these (yet) as the number of available hulls is bewildering. So on to:
Praetorian Industries
The second mod I downloaded, and one with an even more huge variety of overall things available than Uni:T. Though until the challenges are complete I won’t offer full comments about the relative power of the mod, there are a couple of things that do push PI towards the very top of the power tree.
Firstly, the Leviathan hull. It looks fantastic, and in itself I don’t think is too powerful but I have noticed some strange things going on with regards to it that are due to the game, and not the hull itself. Because of it’s size, or specifically its length, when it comes to deciding the “nearest” cruiser (as distances are checked to the middle of ships) even though the Leviathan is clearly nearer than anything else, it can often be ignored for other targets. Not always an issue, but it is very odd to see ships clearly turning away from the honking great ship heading towards them, in favor of other targets instead.
Another issue is that some ships, depending on their armament, can sometimes be nearly crashing into it before they’ll open fire. For these reasons, I won’t be using a Leviathan hull, which is a shame. I just don’t want any results being skewed by odd behavior.
Next, the freighters. For those who don’t have the mod, or do but haven’t realized the advantages this ship gives, these are ships where you can basically build a hull which gives you extra credits for the battle at the cost of a pilot. For example, if the battle is 100 pilots and 10,000 credits, you could deploy a freighter and have 12,000 credits to spend on warships, but only 99 pilots. What this means is that when it comes to deploying cruisers, only the pilot limit matters as basically you can offset the cost of any cruiser by deploying a number of freighters. Though an opponents fleet might cost 10,000 credits, by using freighters you can deploy a fleet of warships that is considerably larger. As such, I won’t be using any freighters in the fleet to follow. It does make gaining honour from the single player missions dead easy though 
Again, I’ve tried to use every hull available, and though I’ve failed, as you read through this long list, you’ll realise I’ve given it a bloody good go. This fleet is also notable for being faster than the majority of my other fleets.
Omega Artillery Dreadnought
When first designed, I equipped this PI flagship with a target booster. Unfortunately it was the destroyer version which, because it was on the wrong hull type, effectively doubled the cost of the ship. After realising this mistake, I took it off for another gun. This ship is basically equipped with a massive Arbalest Artillery Cannon battery to engage the enemy at long range.
Aeetes Assault Cruiser
Due to the hull integrity boost, I decided to use this hull as my basic front rank design. Equipped with pd’s to protect it from missiles, its offensive armament consists of cruiser lasers for their short-range effectiveness.
Panthea Bombardment Cruiser
A very attractive looking hull, and coming with a decent number of hardpoints as well. Accordingly it gets equipped with a number of multi warheads to keep at range.
Milennia Guardian Destroyer
A heavy escort ship, designed to protect other cruisers from both fighters and attacking frigates. To fulfill its role, its equipped with an Anti Fighter Machine Gun and an Anti Frigate Repeater. To assist in taking on cruisers and to continue its protective role, its also equipped with an EMP cannon.
Angelos Heavy Cruiser
To again give the fleet some long range and hard hitting firepower, this cruiser was designed. Another hull carrying ballista artillery, it’s also equipped with a Heavy Tyfonas Beam to cause heavy damage.
Rizpah Torpedo Destroyer
Another bombardment ship, this one comes equipped with one of the heavier missile variants: the Destroyer Anti Cruiser Torpedo. Though it doesn’t have any decoys, should it get through any pd screen, it’s capable of causing significant damage.
Badger Bombardment Frigate
Designed as an escort for the heavy cruisers, to complement their firepower this frigate is equipped with the Gauss Shotgun.
Gryphon Disruptor
Supporting the front rank cruisers, this frigate is designed not to knock down shields, but to take them offline with it’s disruptor bombs. Once the shields are down its equipped with a Throb Beam Laser to cause damage.
Lekho Escort Carrier
This frigate is designed with two roles in mind: supporting PI fighters, and shooting down the enemies. Accordingly, it comes with a carrier bay for repairing fighters, and a Doppelganger Anti Fighter Missile.
Dymas Fast Frigate
Designed for hit and run operations, it moves into range, unleashes its missile launcher before hopefully dodging away and maintaining its range. In practice, they do at times tend to get too close. Increasing its engagement range should help that out.
Elysee Heavy Frigate
There to support the front rank cruisers and to protect them, this frigate is equipped with a Multi Tech AI Virus, an EMP type weapon. To do more than just hinder the enemy, it’s also equipped with a Singularity Blaster.
Ankyra PD Frigate
This ship has one role, and one role only: protect the fleet from missiles. To that end, it’s equipped with a AI Hacking System, a pd system capable of sending any missiles back at the enemy that launched them.
Kyros Shuttle
I love these little buggers. The fastest frigate I’ve designed for any fleet, they’re also tiny making them very difficult targets. Equipping them with Athion Rocket Launchers allows them to do a high amount of damage to any target.
Akron Sniper Frigate
Another tiny frigate, and another favourite of mine. These sit in formation with the bombardment cruisers at the back, providing long range anti fighter coverage for the fleet. To this end, they’re equipped with the Idlesniper Anti Fighter Missile.
Cerberus Super Frigate
A very heavy anti fighter platform, there to protect the front ranks. A tractor beam, pulse laser and rapid fire laser should allow it to chew through attacking fighters fairly quickly.
Dysther Support Frigate
A fairly basic support frigate. An EMP missile locks down the enemy while a beam laser takes them apart.
Psykhe Beam Drone
The basic defence fighter of my PI fleet. Small, fast and armed with a Drone Shock Beam, it’s both difficult for enemy fighters to take out and very capable of bringing the enemy down.
Myron Bomber
There to engage any frigates and cruisers straying too close to the ship it’s escorting, this fighter is equipped with an Archaic Bombing Run System.
Phoebe Defender Corvette
A heavy defence fighter, it has very heavy armour. To allow it to take out enemy fighters, it’s also equipped with a laser.
Lima Heavy Corvette
A very heavy bomber, it’s magnetic mine launcher allows it to take out enemy cruisers and frigates.
Raptor Interceptor
Another fairly standard fighter to win air (space?) superiority over it’s fleet, it’s equipped with a laser to clear enemy fighters and pave the way for the bombers.
Nyx Support Drone
Sitting close to it’s parent cruiser, it’s their to provide additional protection. A Micro Shield Supporter helps keep the shields of it’s parent going for as long as possible.
Fleet Deployment
Phew, that’s a lot of ships and fitting them all into a fleet is very difficult. Two battle groups, each led by assault cruisers with attached frigates form the wings moving to engage the enemy in close. In the centre, drawing the enemy forward is a third group formed from fast frigates and bombardment cruisers. All the ships are on “keep moving” orders; the assault cruisers to break apart enemy formations and disrupt their firing patterns and the bombardment ships to engage then enemy while minimising the fire they take in return.
