ORDINANCE
The Midlands YSF-277 Hirundo packs quite the punch for its relatively small size. It has two partially internal missile bays that each hold 4 air to air "Shrike" missiles, for a total of 8. These bays can be filled with other missiles depending on the mission, but the Shrike missiles are standard equipment. These missiles have an approximate range of 50 to 80 miles and are computer guided while within the 80 mile range.
The primary weapons of the YSF-277 are the 6 ASiM-9 Nuclear-armed missiles. These potent missiles are kept on wing mounted hardpoints that are as close as possible to the center of the jet while still having tolerance for the ignition blast and keeping them from inadvertent detonation from the heat given off from the RF-60 engines.
In addition to the two types of missiles, the YSF-277 has two laser turret arrays on tracks along the wings. These super close range(sub 10 mile) lasers are primarily used to neutralizing quick moving missiles fired against the jet. The round turret hubs can travel along the entire length of each wing while using the fiberoptic line in the track to continuously charge the 250 KW laser. The laser’s have a combined output of 500 KW and when used with the onboard weapons targeting system, they can be both a potent defense mechanism and extreme close range deterrent.
TECHNOLOGY OVERVIEW
RCS AND SCS SYSTEMS
The Midlands YSF-277 Hirundo makes judicious use of a computer aided Reaction Control System and Stability Assistance System to help keep the jet performing at optimal maneuverability parameters and to let the pilot focus on the task at hand instead of keeping the jet flying level. This is especially important at hypersonic speeds, where the G forces can sometimes pull the pilots attention in other directions other than flying. The RCS system uses excess vented heat from the main RF-60 engines to assist the motions the pilot is attempting, primarily in the pitch and roll of the jet. This allows the YSF-277 to make incredibly sharp turns, capitalizing on the already quite maneuverable tendencies of flying wings and being the origin of it's nickname "Barnstormer", referencing the high-speed acrobatic antics of barn swallows. The SAS system tempers these movements and the general instability of the flying wing shape by vectoring the thrust coming from RCS vents. It modulates the severity of RCS assistance based off of the speed at which the pilot changes input direction, allowing very fine control over flight path. These systems working in tandem allow for one of the YSF-277's party tricks. Particularly skilled pilots can execute a 180 degree pitch transition, reversing the forward direction of the jet to fire the more potent Shrike missiles at pursuers. With the relative closeness of the cabin to the axis of rotation in this maneuver, the G forces exerted on the crew are minimal.
C.U.R.I.E. WEAPONS MANAGEMENT SYSTEM
The Central Unified Retaliation Intelligence Engine, or C.U.R.I.E. is an advanced ai weapons management assistant that, like the RCS and SAS systems, lets the WSO focus on taking down the enemy instead of dealing with the intricacies of each of the targeting systems for each type of weapon. C.U.R.I.E. gives the WSO an augmented view of the battlefield around the fighter, highlighting known targets and constantly scanning for new ones, working in conjunction with the standard SWG-654 radar array. The system lets the WSO toggle between the YSF-227's armaments at will, keeping the others primed and at the ready. C.U.R.I.E. can also be switched into full autonomous mode, usually when the WSO needs to administer to the repairs of vital systems, defaulting to a laser dominant defense protocol at an increased range of 30 miles(done by diverting power from the external missile launchers to bolster laser range). C.U.R.I.E. also has mild autopilot features, in case of a malfunction or loss of consciousness of the pilot, and can be overwritten completely for a purely manual approach in the case of reduced power conditions or if the WSO wants a more manual feel. Named after the lady who gave us the gateway to the radioactivity knowledge that lets jets like this fly, the C.U.R.I.E. weapons management system puts guaranteed nuclear destruction only a button press away.
GRAPHINE ALLOY ABLATIVE STEALTH COATING
Graphene plays a vital role in many, many places in the YSF-277's architecture. It helps shield the rest of the fighter from the heat from the engines, lines the fuel tanks in the belly of the fighter, and allows for an incredibly flexible and nuanced electrical grid throughout the craft. Perhaps the most important and extensive use of graphene is in the stealth and heat deflection coating that envelopes the entire craft. The graphene alloy ablative stealth coating, or GAAS coating, provides a nearly transparent coating for the entirety of the fighter that absorbs around 90% of most known radar frequencies, with the shaping of the fighter accounting for another 5%. Not only does this mean that the YSF-277 is quite hard to detect on radar, it also means that whatever paint treatment is used, be it an electroactive active camouflage or other such visual stealth tech, it is not affected by the coating. Since the coating is partially graphene, crystalline carbon, and quartz, it has an incredibly high melting point, around 2697 degrees C. It also has a high heat transference rate, distributing the re-entry heat across the entire plane and off back into the atmosphere. It also is a quite effective deterrent to energy weapons as well, due to its high electrical conductivity. At least 50% of all energy weapon hits are absorbed into the onboard energy supplies. All of this functionality from one base material keeps the fighter safe and hidden from prying enemy eyes.
NGI 16 OBLIQUE-WAVE DETONATION ENGINES
While the P&S RF-60 engines may be the primary, conventional propulsion source for the YSF-277, the reason it can reach to speeds of Mach 10 is due to the Northern Greysteel Industries (NGI) 16 oblique-wave detonation engines. These engines, instead of using the typical burning of high pressure HARP fuel to use exhaust gasses for propulsion, they use a controlled, continuous pressure wave released from the end of the engine. (The exact science of how this works can be seen here. https://newatlas.com/aircraft/oblique-wave-detonation-engine-hypersonic-ucf/?fbclid=IwAR1BvPDVov9__In0Fzqx8g67HdDT03IRx6HBOC5i7maLOyAc1-tNj0Gcyn4) This allows for much higher speeds than even ramjet style engines, even in the vacuum of space. The way the NGI 16 engines are designed not only lets the YSF-277 push the limits of what speeds should be possible with this fighter's shape, it also allows for blistering acceleration. For quick getaways, the YSF-277 can jump from Mach 6 to Mach 10 in about 15 seconds, just the thing for getting out of enemy range to swing around and regroup. The engines also make use of the unique properties of graphene for on the fly refueling. When the fighter drops to Mach 2 or below, the intakes on the front of the engines open slightly and deploy graphene mesh filters to pull in ionized hydrogen or oxygen to replenish fuel stores. This puts the stealth cruising range of the fighter being theoretically indefinite, but that depends on the concentration of the appropriate elements in the area being surveyed.
ACS CABIN PRESSURIZATION
The automatic climate system on the YSF-277 keeps the cabin pressurized and habitable for both pilot and WSO. It also allows for the WSO to act as a technician on the internal access panels at the rear of the cabin. It also helps control the flight suits that keep the crew safe from the extreme G forces they experience during combat. The base ACS flight suit looks like this, with a variety of helmets to choose from, provided that they're fitted with a UCC air tank port.
The ACS flight suit for the WSO has a bit more reinforcement, due to the fact that they face backward in the cabin. They’re locked in more securely than the pilot because of this and are ensconced in the virtual targeting suit that C.U.R.I.E. provides.
