YES MERRY CHRISTMAS!!!!!!!!!!! WOOOO HOOOOO!!!! lol

This made my day!
Couple things I noticed:
Warlords for free. I guess you did this because of all the other upgrades Ork's can buy now? I think a re-roll should NEVER be free.
Warlords again. Is the +2 for "one boarding dice roll" for the entire game? Needs to be re-worded to make this clear.
Re-roll cost. With the multiple options of getting ships with +1 to rolling for ramming elsewhere (can they be stacked???), these should be much more expensive. The main reason these were bought was because it gave the Orks a chance to do their favorite thing, ram. Now the re-rolls are going to be used for SO's, which should be hard to come by.
Squadrons. I am so totally lost by this section I'm not sure where to begin honestly. Let me see if I'm getting this right....
First you determine the size of the battle. Let's say 1500 pts.
This means (as written now) you recieve three Warlords.
Then you determine how many extra re-rolls you want to purchase.
For every re-roll, you MUST get one escort squadron AND one cruiser or Battleship.
Let's say you have a total of 7 re-rolls in your fleet.
So you must buy at least 7 escort squadrons of at least three vessels per and 7 capital ships with the only restriction being you need 2 cruisers to purchase a BB?
Then you allocate the vessels to each "command" of Warlord based on how many re-rolls they have total?
Then if you have any points left over, you can purchase the plethora of upgrades?
Correct me if I'm wrong, but that seems just a BIT complicated and restrictive to me.
Gubbins for Escorts. Should read that "Gubbins purchased for escort squadrons apply to every vessel in that squadron, but each vessel must purchase the upgrade individually". Otherwise it's confusing because it almost sounds like it take only +5 points to uprgrade the whole squadron with ____!!!!
Big Boosters. Should rename them to Soopa Engines.
Looted Lances. Don't like Lances in an Ork fleet unless they only have 15cm range forward firing and armed on a Kroozerm or the special Slambasta lances. No escort sized vessel should have the power supply to arm Lances.
Make Mad Meks dirt cheap. Otherwise, nobody will EVER buy these.
The Klaws. The Rule says you inflict the 1 HP of damage for ramming or boarding. Soooo not both if the Ork vessel can do both? And why not? What are the Klaws exactly? Things attaced to the ship or boarding parties armed with Klaws?
Zukov's Klaw

specifically:
4+ Armor for the rear. When this forum started throwing around the idea of this ship, we wanted it to go after space stations. But with 4+ armor to the rear, the bomber squadrons from the station will rip this ship up! Now I realize you have built the fluff for this, but if your not open to the idea of making the rear 5+ armor, why not increase the base number of turrets? This is advantageous for boarding values too, which is the whole point of this ship! Turret value of 2 or 3 and increase cost by ___ pts per turret. I have no beef with that.
Is this a character ship? Becuase it should be listed in the Ork fleet list if it is. And, if it is, it should get something to make it more.... unique. Like, allowing two teleport attacks! Gives it a reason to actually HAVE a name. Otherwise, take it off the pdf since the rules are explained quite clearly on what upgrades an Assault Kroozer has and this offers nothing to the document as a whole.
You made a mistake at the bottom of the special rules. You said it can't go on All Ahead Full. I think you meant Come to New Heading?
Light Kroozer:
Design phiolosophy. I see the stats are for a captured Endeavor class but the model illustrated would tell me it's more of a Dauntless. I think we should get stats for both variations

The Dauntless variation for instance should have D3 Gunz for each broadside and D6 Gunz to front and 6 Heavy Gunz or D6 torps to front! The Endeavor should be D6 Gunz to each broadside, D3+1 Gunz to front and D3+1 Torps or 4 Heavy Gunz.
Grunt Assault Ships:
Increase the Boarding value back to 4. It's going to be hard to get any more than 2 of these guys into base-to-base contact with an enemy at one time so 2hp boarding value will make it really hard in my mind to be worth it.
Just my 2 cents
