Can't buy Battleship

[Rammstein]

hello everyone!

ok here is the story:
i want to buy the hellfire legion battleship namend "Arbiter" so i made new character and restartet lihellfire. then i went to the suppling base to buy the battleship but any time i want to buy it the console say some like ERR you cant buy this ship because u aint got the right id. well hellfire legion id comes with the restart and the reputation also. iam flashing with hellfire legion and got id mountet but iam not able to buy the ship.

someone told me i have to get it by SRP

so heres my question:
do i have to get the ship by admin after i got some SRP threath to force the ship?
and if so can someone explane me how to do it correct?

if not so why can't i buy the ship?
