F-28A "Black Eagle" Multirole Fighter

Overview

The development of the F-28 Black Eagle aircraft began with a requirement outlined by the Aequatian Republic Air Force concerning the vulnerabilities of the venerable F-1C Banshee and later F-1D Nyx strike fighters. While they performed well in air combat versus enemy aircraft, their designs left them vulnerable as they produced a signficant radar cross section compared to their modern counterparts elsewhere in the world. The design called for a fighter which combined the immense strike capabilities of the F-1C Banshee while at the same time have a considerably less prominent RCS.

Construction and Design

Most of the fuselage and wing assemblies are constructed from a triangular design for strength with a Titanium-Lithium (Ti-Li) alloy The alloy was chosen for both its strength and light weight, for increased combat efficiency. The remainder of the aircraft's construction consists of an Aluminium-Lithium (Al-Li) alloy for econimical purposes, although this does not detract from the material's strength or durability, thus decreasing maintainance costs.

The aircraft itself is modelled to provide it with the least possible radar cross section (RCS) as well as the addition of radar absorbing materials on the exterior of the fighter, its diamond-style wings and wide fuselage allow for increased lift and also for an increased weapons load when required for strike missions while the internal bays can manage air superiority weapons while maintaining its stealth characteristics along with its canted rear vertical stabilizers. The canards seen on the F-1C Banshee were not chosen for this design as they increase the RCS and were subsequently eliminated from the design.

Combat Systems

AN/APG-100 Active Electronically Scanned Array (AESA) Radar offers a low-observable, active-aperture, electronically-scanned array that can track multiple targets in all weather conditions as well as act as the aircraft's navigation radar. The AN/APG-100 changes frequencies more than one thousand times per second to reduce the opportunities of being intercepted and jammed effectively. The radar can also focus its emissions to overload and enemy sensors, giving the fighter a limited electronic-attack capability.

The radarís information is processed by two Aequatian Electronics Dynamics-built Integrated Processor Units (IPUs). Each IPU operates at twelve billion instructions per second and has five hundred megabytes of memory. Information can be gathered from the radar and other onboard and offboard systems, filtered by the IPU, and displayed with an easy interface, allowing for maximum operational awareness for the pilot. The system's software is composed of over two million lines of code, most of which concerns processing data from the radar. The APG-100 radar has a range of two hundred forty kilometres, planned upgrades will allow a range of four hundred kilometres or more in narrow beams.

Aequatian Aerospace Industries "Crystal Ball" Infrared Search and Tracking Suite (IRST) allows the aircraft to detect and move to engage targets at close range without detection thanksto the fighter's use of stealth technology for reducing its radar signature and without the use of the APG-100 system.

AN/ASQ-220 HARM Targeting Systems (HTS)

AN/APX-115 Identification Friend or Foe Set (IFFS)


OOC: Not entirely finished, but could use some comments to make it better.

On a quick read-through, it seems rather nicely thought out. Just a few points:
The 8 external hardpoints may be a little excessive, both in weight and drag, but that's a matter of opinion.
I'm also not too sure about your forces - the balance of weight, thrust and thereby speed. Your weights seem right on, but what I don't get is how you hit higher speeds that the Raptor with less thrust. For reference, the F-22 Raptor gets 158kN of thrust per turbine and hits around 2.4M, from what reliable data I can find.

Besides that, very nice. A good blend of weaponry, which is often tricky.

The external hardpoints would only be used for larger strike missions, think of them as secondary to the internal bays. I'm having this aircraft use more of its stealth for defence than extra weaponry.

I'll re-adjust the speed a little then, bring it down somewhat.

Thanks for the input.

On a purely superficial and aesthetics level, it sort of resembles more like the F-35 than F-22...

SEA: this is not the place to discuss the image, purely the design
