Star Trek Excelsior Class Starship (Stock)

The Excelsior Class Starship, the longest serving class of vessel in Starfleet, replaced the aging Consitution classes as the new heavy cruiser. First introduced in Star Trek III: The Search for Spock, and appearing later in The Next Generation and spin offs.
Built to scale provided by the blueprints:

The Excelsior is larger than any of my previous starship classes and will REQUIRE experimental mode to be turned up with block limits turned OFF.

As like my Constitution Refit and Miranda Class Starships, this ship was built before the hydrogen generator, so if you plan on using this in survival, you must install a hydrogen generator connected to the conveyors.

The ship features
~20 jump drives
~700 gyroscopes (Seperated for Saucer and Stardrive)
~200 batteries (Seperated for Saucer and Stardrive)
~1000 Ion thrusters (Stardrive)
~400 Hydrogen thrusters (Saucer)
Saucer Seperation
2 Hangars, Cargo at the rear of the stardrive, and shuttle bay at the lower end of the stardrive
Ship's Beacon & Plaque
10+ Cargo Containers
3 Refineries
18 "Phasers"
10 "Photon Torpedo turrets"
2 "Photon" Launchers

The ship is pressurized with multiple air vents, the interior is mainly empty to allow user customization. No mods/addons/blocks of any sort is needed nor required on the ship but you are welcome to customize it to your own leisure.
The ship is painted to the confirguration of that seen in the Star Trek VI: The Undiscovered Country with the colour scheme similar to that of my refit consitution and miranda class starships.

Update:
Found the leak it is located on the port and starboard ends of the saucer on deck 3, where there is a gap open above the ceiling which lead to the hydrogen thrusters.
