The Persian Gulf destroyer project is still in the planning phases remember. That model you are complaining about is already radically out of date:
Old design
Latest known Design
The design is still changing and when new systems like the VLS B-373 are made available, they will most probably be included when the final product is a 7500 ton destroyer that will be the flagship of the navy.
I basically updated the work of Sean O'Connor on his blog. The files are still publicly available (though difficult to find, it took me hours). I did not search for any additional sites partly because I don't want to reveal the locations of them, and partly because it would be quite hard to look through all 1.6 million km^2 of Iran.
