The EA-220 Joint Tactical Bomber is the result of a long multinational development program and is probably the best aircraft in its field to date. Nations were handpicked by the Elias Ministry of Defence Procurement and Export due to their expertise in various areas of design and construction so quality and reliability is obviously of the highest possible degree.
The aircraft itself is designed to provide Carrier Battle groups or Air Force Strike wings with an unrepresented ability to penetrate enemy air space and delver large amounts of ordnance accurately while being able to escape due to stealth technology, countermeasures and capacity for air to air weapons. The other main consideration was that the aircraft had to be flexible as nations all use different weapons and have different requirements; this goal has been achieved mostly due to the open architecture computer systems developed by Crookfur.
Elias Aerospace along with its partners without which this plane would never have come into existence are extremely proud of this new design that took much time and money to develop although the rewards in capability are most worth it.
Project Partners
United Elias: Design, Final Assembly, Flight testing, Powerplants, project management: 35%
Dark Terror: Wing/Fuselage assembly: 20%
Phoenix Militia: RAM coatings, Internal Weapons bays: 10%
Ferrussia: Ejection seats, fuel system: 5%

Design and Structure
The wings and fusalage are made of composite materials and covered with Radar Absorbent Materials (RAM). This ensures that the EA-220 is extremely low-observability.
The EA-220 delta-wing design, without getting into too much aerodynamics here, is what is known as a lightly loaded wing. Such a design offers some unique challenges in handling the flight control system and making it adaptive to the environment that the EA-220 is designed to be in, which is a very low-altitude, high-speed state as it penetrates enemy defenses.
The wing area of the EA-220 is 1309 ft. sq., more than twice as large as the A-6's wing area. Flying wings generally have a large wing area in order to compensate for their lower lift capabilities. The wingspan of the EA-220 is 70 feet, 3.2 inches and it is 37 feet, 3 inches long.
The EA-220 has a straight trailing edge. Along the trailing edge are pairs of elevons at each wingtip and pairs of spoilers forward of them. A pitch flap is located in the center, above the engine exhaust area. Yaw control is designed to be provided by differential drag at the wingtips. All flight controls are integrated in a quadruple redundant fly by light control system.
The EA-220 uses reinforce titanium alloy landing gear and on the carrier version full arresting gear, which has been fully tested for durability and fatigue

Cockpit and Electronic Systems
Cockpit:
5 Multiple Multifunction displays in both pilot and WSO stations showing complete tactical data, conventional glass dial back ups in case of electronic systems falure
Wide angled HUDs, with CCIP indicator and threat indicators.
Helmet mounted systems offering HUD abilities, weapons targeting and cue and imposition of imagery from sensors and targeting systems.
Controls: VOTAS with adjustable positioning of main flight stick.
Navigation:
Laser ring gyro Inertial navigation system, open architecture satellite system (since there are numerous NS GPS systems), radio compass ability, full terrain following autopilot with terrain avoidance system for low level flight.
Sensors:
MK5004 sensor system
Multi mode Electro optical/ IR scanning system with ground tracking, targeting and lasing abilities (with up to x50 zoom and the ability to las up to 4 targets at once) and air to air IRTS mode (up to 200 targets at 120km).
CFES MK4015M
Based on the Mk4005 entered for the FC multi role fighter the 4015M model place more emphasis on a ground surveillance mode, air surveillance can still track up to 20 simultaneous airborne targets (for zero emissions operation it can use data supplied by other platforms including AEW/AWACS) in air search mode the high definition scan can give detailed returns on targets over 500km distant.
As with the 4005 the MK4015 is more than just a radar but a complete target identification and engagement management system with automatic threat prioritization and combat analysis (MICA already does this but I’m expanding it into the air to ground mode).
As an added extra for the stealthy nature of the JTB the MK4015 has a number of low emission ground surveillance modes.
The first mode is completely passive and relies on gathering returns from signals generated by other platforms (kind of like the UAVs they are proposing for the E3 but using GS systems) as well as enemy emissions. The second mode uses a very low powered but highly focused beam to provide a stealthy short range surveillance mode giving medium detail.
Air search: 370km
Detail scan: 500km
Surface scan (full power) vs. large targets: 500km
Surface scan (full power) vs. small targets: 150km
Surface scan (stealthy) vs. large targets: 150km
Surface scan (stealthy) vs. small targets: 45km
Delivery systems:
Air to Air: Standard installation covering US systems and MICA/ASRAAM, optional modules for soviet/indigenous systems.
Bombs: Full compatibility with laser, IR, GPS/INS and EO targeting, radar targeting in concert with Stand off radar imaging platforms (In a very recenttest a J-STAR guided a bomb) or in built systems (i.e. this lot offers full any condition engagement of both stationary and mobile targets.
Missiles: same as bombs and with support for Stand off weapons and microwave targeting for tactical weapons.
Gun: targeting using best senor for environment.
A fully integrated system where the plan selects the best weapon for the Rules of Engagement and mission type so that the pilot/WSO chooses the target from the data that is gathered by all systems, a data link to other units is of course included for those who like the info sphere idea and so your Forward Air Controllers can double check your targets (if you use Rather gung-ho pilots).
Countermeasures
Full automatic radar/ millimetric/ laser illumination detection and threat warning, missile launch warning system, active counter measures including 50 round chaff/ flare/ DPS launcher and active IR/ laser missile dazzler system (the laser is for those rather annoying ImRec missile some bugger came up with, its just one emitter but the beam works well against both IR and EO seeker heads).
Weapons
The main bay has an 8 panel retracting door with a split in the middle. Electronic servo motors provide quick opening and closing of the main bay. Should electronics fail for whatever reason a hydraulic system opens the doors at a slightly slower pace. Whether they are open or closed the main bay doors do not protrude from the fuselage.
1 main bomb bay, w/ 9 mounting points 7 of those can accept double mountings (bombs of various types, a variety of ASMs, ALCMs or ARMs)
2 inner wing bays (AMRAAAMs, bombs, HARM, Maverick, Harpoon, Rainbow etc) [also can take extra fuel tanks]
2 outer wing bays (AIM-132 ASRAAMs, AIM-120 AMRAAMs, Maverick, SHRIKE, etc.)
2 inner IR guided AAM ports (AIM-9X Sidewinder or AIM-132 ASRAAM etc)
1 Gsh-6-23 (http://www.shipunov.com/shipunov-e/str/cannons/gsh6_23.htm)/ Gsh-6-30 (http://www.zid.ru/en/products/military/gsh30.html) interchangeable gun systems
Summary:
Outermost wing bays will hold 2 AMRAAM or Sidewinder missiles, inner wing bay will hold 2 AMRAAM, HARM, Maverick, Harpoon, Shrike, Rainbow or 4 rockyeye cluster bombs or 2 500-1000lb bombs of multiple types etc or 6 Small Diameter bombs. Main bay will have 9 points they can hold up to 14 500lb bombs (7 points will accommodate double mounts) or 9 2,000lb bombs such as the LGB or a bunker buster bomb. It would carry a total of 22 Small Diamter Bombs in the main bay also 2 in the wing bays = 24 Small Diameter bombs)
Powerplants
The Elias Precision Engineering Corporation has designed the high technology EPE-136M2 turbofan engine specifically for the JTB. (18,230lb of thrust each)
They include the following features:
-Integrally bladed rotors: In most stages, disks and blades are made from a single piece of metal for better performance and less air leakage.
-Long chord, shroudless fan blades: Wider, stronger fan blades eliminate the need for the shroud, a ring of metal around most jet engine fans.
-Both the wider blades and shroudless design contribute to engine efficiency.
-Low-aspect, high-stage-load compressor blades: Once again, wider blades offer greater strength and efficiency.
-Alloy high-strength burn-resistant titanium compressor with innovative titanium alloy increases durability, allowing the engine to run hotter and faster for greater thrust and efficiency.
-Alloys in augmentor and nozzle: The same heat-resistant titanium alloy protects aft components, permitting greater thrust and durability.
-Floatwall combustor: Thermally isolated panels of oxidation-resistant high cobalt material make the combustion chamber more durable, which helps reduce scheduled maintenance.
-No visible smoke: Reduces the possibility of an enemy visually detecting the plane
-Improved Supportability: All components, harnesses, and plumbing are located on the bottom of the engine for easy access, all line replaceable units can be removed with just one of the six standard tools required for engine maintenance.
Fuel and Range
The plane will carry two fuel tanks, one in each wing. Both tanks will be connected, with a small integrated computer system controlling flow between the tanks if necessary. The system will be accessible from the cockpit, so the pilot can take over manually. A backup physical control will be situated in the cockpit as well, in case of computer malfunction.
The program and connections will ensure that in the event that one engine is disabled, fuel is given to the other engine, or if a fuel leak is detected, fuel can either be pumped into or out of the leaking tank, depending on whether both engines are needed.
A small backup tank situated in the middle of the plane provides some fuel reserves, so that the actual range of the plane is slightly farther than what the fuel systems and official range state. This is also connected to the automatic fuel distribution system.
Finally, up to two of the weapons bays can carry fuel pods. These, too, are wired into the distribution system.
All aspects of the distribution can be sealed off within .025 seconds.
In-flight refueling:
the EA-220 will have both probe-and-drogue as well as boom refuelling capabilities. The boom will be like that of the SR-71, but with an automatic cover to reduce chances of radar reception and increase the streamlined shape.
SR-71 boom port (http://www.sprucegoose.org/images/Refuling%20Port.jpg)
The probe-and-drogue facilitations will look like this (http://www.b-domke.de/AviationImages/Foxhound/Images/2047.jpg), except recess within the plane itself, again with an automatic cover.
Ejector seats:
When necessary to eject, an automatic system can be activated by either the pilot or weapons officer. The Automatic Personnel Ejection System (APES) blows the canopy screws with very small shaped charges, and then detonates additional charges that blow the canopy off the fuselage. A final charge deploys a small parachute in a small integrated structure in the back of the canopy. The parachute slows the airspeed of the now free canopy, and the entire process of events takes a matter of milliseconds.
At this point, the system ignites charges beneath the seats which detach it from the cockpit at specific points. A small solid rocket booster ignites beneath each seat, propelling the crew about 2-300 feet above the plane. A supplemental oxygen system is activated (via the helmet) if the air pressure is low enough to pose a health hazard to the crew. A large parachute is stored in the back of the seat, which deploys automatically when either G-forces become too high or the altitude is less than 2-3,000 ft from the last reported ground level. Provisions are also made for pilot-initiated deployment of the parachute. An additional strap-on parachute is in a small and easily accessable compartment, in case of malfunction or other reasons that make it necessary to disembark from the chair.
All of the APES subsystems can be activated manually if necessary. The pilot is free from the plane in a calculated .225 seconds from activating the APES system
