Engineering Complexes are a new type of structure introduced during the Ascension expansion. These structures, and the service modules that came with them, are intended to replace research and manufacturing functionality currently available in Outposts and Starbases. Engineering Complexes gain bonuses to manufacturing/science jobs and engineering service module fuel.

Some of the key similarities between Engineering Complexes and Citadels are:

• Both Engineering Complexes and Citadels are built and deployed in the same way, with the same deployment location restrictions (not allowed in certain newbie or trade hub systems, must be placed at least 1000 km from other Upwell structures). Both use the same 24-hour anchoring process
• Both Engineering Complexes and Citadels use the same vulnerability, reinforcement and damage cap system for defense. The damage caps for each size of structure remain the same whether that structure is a Citadel or Engineering Complex
• Both Engineering Complexes and Citadels use the same asset safety system for recovering contents when destroyed or unanchored
• Both Engineering Complexes and Citadels use the same access list system for managing access to the structure and its services
• Both Engineering Complexes and Citadels use Standup-brand modules and most of these modules can be fit to both types of structures. All the Citadel Service Modules can be used in Engineering Complexes, and most Engineering Service Modules can be used in Citadels
• Both Engineering Complexes and Citadels are dockable and include tethering for nearby friendly ships. All core functions like refitting, contracts and direct trade are available in both lines of structures
• As we continue to add new core functionality to Upwell structures over time (such as the planned future additions of insurance and docked repair functionality), these functions will generally be added to all Upwell structure lines

Some of the major differences between the two classes of structures are:

1. While Citadels gain bonuses to combat rig strength and Citadel service module fuel use, Engineering Complexes gain bonuses to manufacturing/science jobs and engineering service module fuel use instead.
2. Engineering Complexes are significantly less expensive than Citadels.
   • Medium Engineering Complexes will cost approximately 40% less than Medium Citadels
   • Large Engineering Complexes will cost approximately 60% less than Large Citadels
   • XL Engineering Complexes will cost approximately 90% less than XL Citadels
3. Engineering Complexes have longer vulnerability periods and fewer hitpoints than Citadels
   • Each size of Engineering Complex has 33% fewer hitpoints than their Citadel counterpart
   • The Medium Engineering Complex will require 9 hours of vulnerability weekly, with 14 hours and 26 hours for the Large and XL Engineering Complexes respectively
4. The two larger sizes of Engineering Complexes have more limited docking abilities for their size compared to Citadels.
   • Medium Engineering Complexes allow docking of subcapital and Freighter vessels, the same as their Citadel counterparts
   • Large Engineering Complexes share the same docking restrictions as Medium structures. They can build capital ships and launch them from the internal dry docks but cannot accept docking of capital ships from outside
   • Extra Large Engineering Complexes share the same docking restrictions as Large Citadels. They can accept docking of normal capital ships, and can launch supercapital vessels from their internal dry docks, but they cannot accept docking requests from external supercapital ships
   • These tighter docking restrictions are what allowed us to keep the price of Large and XL Engineering Complexes so much lower than their Citadel counterparts without causing major balance issues

The namesake of former Ishukone weapons researcher Tyma Raitaru, who pioneered the invention of modern day missile, the Raitaru is the smallest of the three Engineering Complexes and is comparable to the Astrahus in size and scale, offering facilities to manufacture anything except for capital and supercapital class hulls.

Similar to the Astrahus, the Raitaru will be able to accept all sub capital ships into dock, along with the Orca, Bowhead and freighter class hulls. Anything larger (capital or supercapital) however, will not be able to dock. This medium sized engineering facility provides an inexpensive way for corporations to build their own base of industrial activities.

The next step up from the Raitaru, the Azbel class Engineering Complex will perform the same functions as the Raitaru on a much larger scale, and even offers the option of being able to construct capital vessels.

Named after Li Azbel, a Gallente scientist who pioneered the first breakthroughs in faster than light communications, this massive structure would make a worthy home for a large industrial corporation or alliance.

The Azbel is larger and better defended than the Raitaru, offering more sustainability and flexibility. Typically designed to be used a large scale manufacturing center for research, copying, invention and manufacturing, it gains the generalization benefits of large sized engineering rigs to allow individual structures to provide a greater variety of bonuses.

The largest of the three structures, named after one of the co-creators of the first Caldari jump drive, the Sotiyo-Urbaata Drive, the Sotiyo serves as a large scale manufacturing and assembly site for everything from sub capital ships and modules up to supercapital class hulls.

The Sotiyo will be able to accept capital class ships into its docking bays, and will be able to install services for the production of the largest supercapital ships in New Eden.

Thanks to the generalization benefits of larger structure engineering rigs, one Sotiyo will be able to receive bonuses to all forms of manufacturing at once if desired, providing great convenience for its hard-working residents.
