Show me evidence in the 40 k rulebook, epic rulebook, space marine codex or the bfg rulebook armada or otherwise that they even exist. Those books are the only ones that matter.
And as books have shown, SM can get stuff which come from the time of the Heresy. Ven Dreads as pointed out are one.
You are letting your rampant fanboyism for space marines come before anything else. Also, vaaish also expressed his dislike for them.
Vaaish has already disputed you. You're the ONLY ONE here opposed to ideas of a VBB which only comes in one per SM list, which I even prefer to limit to First and Second Founding Chapters, which I even prefer to limit to minimal Lance battleships (preferably with Launch Bays), which I wouldn't even mind being limited to 1 in 1,500 lists.
Fanboyism? If I am letting any fanboyism affect me, I would be fighting for the SO and this current proposed list. If you cannot even identify what fanboyism is, please DO NOT apply it to others when it is so BLATANTLY OBVIOUS that there is none. While I have played Space Wolves in 40k, I have also tried IG, DH and even Nids. I played Space Wolves because I like their fluff which is where I based most of my SW list from. Also, just to add further info for you, I was never heavily into 40k (as much as I am into Warmachine Hordes right now). I do read up on their fluff but as of this year, I can truly say I am 40k free since I traded off the last of my 40k stuff.
Space marines are NOT important in this setting. If you desire to play with imperial navy ships, play imperial navy. If you want to play with chaos ships, play chaos. Stop trying to turn this game into 40k
Again you accuse people of making this game into 40k. What makes you think we want to make this game into 40k? By adding the VBB? Are you that afraid of a VBB that you think it translates into an automatic win for SM? Really? Wow! If those battleships were that cool then I guess IN and Chaos ought to be really dominating every race since they have access to those wonderfully, uberpowerful battleships which can sweep the enemy fleet off the table and that by adding that one ship to an SM list, we have now turned the game into 40k where SM will start DESTROYING every list that goes up against it.
How scary. NOT!
