I have been thinking, and decided that if I am going to start to do this AU again... then I will start from bottom and going up!
A map I made:
the world of 7 kingdoms, that in the end becomes Haram after a 100 year war... "as the books say!", but the world is more like Game of thrones in the start, that ends up as Haram after several years of wars. (that my back story for the AU, and I think that explain almost everything! no need to write an 10000 word back story about this AU, other people can do that!)
Thus I will first start with all smaller vessels, the true backbone of any Navy, the workhorse of a Navy!
So tugs:
small compact naval base tugs:
Young class, small tug was build mainly to help moving around equipment and assist submarines and bigger tugs in there task.
Boy class, was an more powerful version of young class, it was also bigger. This Harbor tug did all the heavy work of getting all larger ships in to harbor in Harams larger Naval bases, the class was also used at Haram 4 Naval shipyard, and at Haram underground bunker shipyard and maintenance facility.
Pegaus class was designed mainly to pickup aircraft carriers and Battleships and help them in from the open ocean in to Naval bases placed up rivers. Pegasus often operated together with Orion class heavy Tug.
Orion class Heavy tug, it was build to do the heavy work, if you needed to tow an aircraft carrier from one end of the country to the other side, she was the Tug for the work. are you scrapping an ship from the mothball fleet, and have to send it half way around the world... she was the tug for the task.
Pluto class long range support tug, need to move heavy equipment or a mobile dock to an another place in the world, because you are going to do an invasion... she is the tug to do the work, Her long range, capability to tow at an much higher speed and capability to carry armament and have a large crew made here ideal tug to take in to a war zone. in peace time they would work as an standby vessel.
