First, I'd like to apologize in advance for the massive wall of text that follows.

My gaming club has recently gotten into BFG and I would love to create a fleet to compliment my 40k army, which is Dark Angels Space Marines. To accomplish this task, I have chosen to use the Battlefleet Armageddon fleet list so I can use Imperial Navy vessels to cover the weaknesses of the SM ships. The fleets I can be expected to face in my club are Eldar, straight up Space Marine, Chaos, and Adeptus Mechanicus. My goal is to create a competent and semi-competitive list to have fun games with my friends while still staying true to the fleet's theme.

Being a SM fleet, the theme is to have the core of my fleet be SM ships while having the IN back them up. In gameplay terms, that means starting with SM ships, and then picking IN ships to cover their weaknesses. The following is an attempt at just that, with reasonings as well.

Fleet Admiral 50
- 1 re-roll 25

From researching all the various fleet lists, this seems to be the stock choice in fleet commander, I would assume because of it's cheapness.

Space Marine Strike Cruiser x3 435
+ fast
+ maneuverable
+ T-Hawks
+ 6+ armor
+ bombardment cannon

- short range
- 1 shield

I feel like the Strike Cruiser is the iconic SM ship and as such should be the "core" of my fleet. Fluff wise, the SC are pushing through the enemy to get to whatever their objective is while the IN support them in this goal. Obviously, I squadroned them up to attempt to increase their survivability, but the only solution to their short range is to rush them in while other ships lay down cover fire. Which leads me to

Imperial Emperor Class Battleship 345 (or 350?)
+ all long range
+ carrier

- no lance
- no nova

The great thing I found about this ship was that ALL of it's weapons are 60cm, which aside from NCs is the longest range any IN weapon can fire. Bonus is the great carrier capacity of the ship. This also seems to be a stock choice for most fleet lists I've seen, so I must be on the right track. I do have one question though, the profile lists Shark AB in the launch bays, but then says you can purchase Sharks for 5 points. Is the profile right and 345 is the price for with Sharks, or is it 350 with the Sharks?

Imperial Lunar Class Cruiser (NC) x2 400
+ lances (short range)
+ nova cannon

- short range other then NC

I debated on this section, at first I had Mars battlecruisers, but ultimately I felt they were too expensive. This gives me 2 NCs in my fleet, as well as some lacking lances for when they close. Not much else to say on this.

RSV Firestorm x5 225
+ fast
+ lances

- fragile

I felt like I needed more SM ships, that I needed some escorts, and that I still lacked some lance firepower, so the Firestorm fit the bill for all 3. I originally went for Novas, but I found I was able to fit an extra ship in the squadron if I went for RSV Firestorms and all I was losing was speed.

Total 1480 (or 1485)

The idea of the list is to have the SM vessels rush the enemy while launching T-Hawks to get their short range guns to bear, while the IN vessels use their longer range guns and ordnance to close more slowly and support the SM ships. My biggest concern is simply that I don't have a lot of ships to my fleet, but I wanted to at least try to come up with a list before asking the more knowledgeable at large. So my ultimate question is, is this an effective strategy/list for non-tournament play, or am I way off my rocker here and don't know what I'm doing in the slightest? Any help would be much appreciated.

Slightly off-topic, obviously my SM ships should be painted in my chapter's colors, but is there a standard for IN ships or are they as varied as IG regiments?

Thank you very much to any responders.
