The headquarters of the Ultimates and S.H.I.E.L.D., this facility is an artifical island located five miles off the coast of New York City. The facility itself is known to the public. The Triskelion has these ingrained capabilities:
-Armory: The Triskelion has a very large assortment of personal arms for the Ultimates and S.H.I.E.L.D. soldiers to use while fighting evil. This armory stores all of the S.H.I.E.L.D. varied gear, from flame throwers to laser rifles to rocket launchers. Furthermore, it's got a bevy of spare ordinance and firearms, should combat occur within the facility.
-Backup Power: in addition to the main generator hard-wired into the Triskelion's foundations on level 5, S.H.I.E.L.D. have installed a backup generator with which to keep their systems up and running in the event of a catastrophic failure of the main power plant. This backup generator has the same staying power of the primary (about six months, assuming the generator fuel tanks are full).
-Briefing Rooms: on level two of the Triskelion, one can find three different meeting rooms, each with a different purpose. The first is the situation analysis room, where current hot spots are tracked by S.H.I.E.L.D. intelligence ops, the second is a holographic imaging chamber, with which S.H.I.E.L.D. soldiers can truly plan for enemy fortifications and the like, and the last is a generic meeting room, used when the others aren't necessary.
-Communications Room: on the second level of the Triskelion, between the secondary staging area and the holographic imaging room, is the S.H.I.E.L.D.'s primary communications facility. Usually staffed by S.H.I.E.L.D. specialists while he's on duty, this room has equipment that allows S.H.I.E.L.D. to keep tabs on their operatives in the field, wherever in the world they happen to be.
-Computer Room: all of the systems in the Triskelion are controlled by a central computer bank that is located on the fifth level, where it can safely weather almost any calamity save for a complete rout of S.H.I.E.L.D.. This computer has links to the Pentagon's computer network (via a secure land line wired into the second level) as well as most other, secured law enforcement agency databases.
-Garage Package: the first level of the Triskelion primarily consists of a large vehicle storage bay, one that can accommodate a large array of vehicles and towed implements of destruction. One could probably fit over a dozen S.H.I.E.L.D. tanks within this space, assuming S.H.I.E.L.D. felt the need to have ten of them built at any one time. The garage also has two large hydraulic lifts for moving gear up to the surface and back.
-Gym Package: half of the Triskelion's third level is composed of a large training area meant to keep the Ultimates or S.H.I.E.L.D. soldiers on their toes. It is fully equipped with sparring mats, target practice bays, combat dummies, and even a full-length pool, for swimming laps! Of course, when training S.H.I.E.L.D. for special missions, the gym can be fitted with all kinds of unique training mechanisms with which to prepare them for field conditions.
-Life Support: the Triskelion is equipped with completely internal utilities, such as power generators, atmospheric recycling apparatii, and food and water stores capable of keeping the Triskelion fully functional for six months, its bottom two levels doing so completely sealed off from the outside world. Furthermore, every level (and every room within) can be sealed off by the Triskelion's main computer, if necessary.
-Living Quarters: the Triskelion has a very large space for living quarters on level four, basically consisting of all of that floor which isn't already taken up by the armory. There are enough bunks to man about a hundred S.H.I.E.L.D. soldiers on this level, though there are also twelve special 'suites' for the Ultimates, commanding officers, visiting dignitaries (assuming they have the proper security clearance), and the like.
-Power Room: this massive generator, built into the foundation of the Triskelion on level 5, is powered by standard fuels, and capable of running for six months in a pinch, should external power to the Triskelion be cut off. Should this occur, the generator will switch on immediately, causing a minimal loss of electricity and ensuring that S.H.I.E.L.D. doesn't find themselves caught without computer support in an emergency.
-Staging Areas: the Triskelion has two large staging areas, spaces designed for S.H.I.E.L.D. to muster their forces for a mission. The primary staging area of the Triskelion is on level three, adjacent to the gym, whereby Joes can move their gear straight from the training stage of a mission to the preparation stage. The secondary staging area is on level two, where further gear and heavy ordinance can be stored in a pinch.
-Hangar Package: though the S.H.I.E.L.D. house their heavy duty aircraft, helicopter gunships and other V.T.O.L. vehicles within the Triskelion. These are kept in an expanded portion of the vehicle bay on the Triskelion's first level, and have access to the surface thanks to their very own hydraulic lift and motor pool 'expansion' building.
-Kitchen Package: with the rampant growth of the S.H.I.E.L.D., it became necessary for S.H.I.E.L.D. to have their own source of food, instead of just sharing space with the chaplains above them. The team has months worth of canned goods, meat, and frozen foods available, the equipment to prepare such food and a mess hall to serve it in.
-Laboratory Package: usually manned by Bruce Banner, Henry Pym or Janet Pym, this electronics laboratory is fully stocked with all kinds of electronic testing gear, reams of spare components, and a bevy of experimental, yet classified devices that you're not cleared to know about.
-Medical Package: situated on the third level of the Triskelion, S.H.I.E.L.D. added an infirmary within their headquarters, as the membership of their unit has grown considerably; This facility is fully equipped with operating bays, essential medical supplies, and everything needed to patch soldiers up after a mission.
