Description
Light Strike Fighter -186 'Sabre Dart' Starfighter. Updated.The Nexus Aerospace Light Strike Fighter – 186 ‘Sabre Dart’ is a third-generation starfighter used by the Escean Interstellar Navy for fleet protection and enemy interception. First deployed in 2099, the Sabre Dart is a small, singe-seat fighter capable of interatmospheric operation. As a carrier-based fighter, the Sabre Dart is typically transported by a Pandoran-class capital or Mystique-class assault ship, although a tricycle undercarriage allows them to deploy from planet-side airfields.
LSF-186s are among the fastest of their type in existence. Each craft is equipped with four Hatsun 50kW Ion Thrusters for transit propulsion, RCS clusters for zero-atmospheric manoeuvring, and two FPE-81 Fused Propellant Engines for combat propulsion. The main engines, which vent plasma from the onboard reactor, provide enough thrust for the craft to achieve planetary escape speed. In combat, these engines allow the Sabre Dart to rapidly accelerate for interception or evasion. The plasma flare released from each exhaust extends over 100m aft of the fighter, and can reach temperatures in excess of 1 million degrees, posing significant hazard to anything behind it.
Lightly armed, the Sabre Dart was built upon experience gained by Escean fighters during the Resource War. Much like terrestrial fighter aircraft, the Arrowhead starfighters utilised in that conflict were equipped with guided weaponary in addition to a small rotary cannon. This loadout proved largely ineffective in space combat, where the complexity of space-launched interception missiles increased size and restricted explosive and payload capacity. Furthermore, CIPDL (Close-In Point-Defence Laser) cannons easily swatted these missiles. The 20mm cannon simply lacked adequate energy to deal significant damage to enemy craft using shielding or hard armour.
The Sabre Dart therefore did away with guided fighter-to-fighter ordnance, with its only guided munitions being ground attack weapons stored internally in the belly. For engaging enemy craft or ships, the LSF-186 relies upon a pair of repeating 20mm K-64 Gauss cannons with an internal capacity of 1600 rounds. The velocity of the solid tungsten carbide slugs gives the Sabre Dart considerable punch, enough to destroy enemy fighters and even damage enemy ships. These projectiles are also incredibly difficult to defend against given their size and speed.
For obvious reasons the Sabre Dart’s canopy does not utilise any form of glass or composite alternative. Instead, it is armoured and opaque, with the pilot observing the outside through an array of cameras and an internal projection screen. Flight controls are haptic-based, with physical backups for catastrophic loss-of-power situations. In emergencies, the pilot may eject from the craft inside the cockpit ‘tub’. This is created when the canopy seals, creating a reinforced shell. The armour of an LSF-186 is fabricated from composite materials, ballistic fabrics and carbon nanotube plating. The entire aircraft uses composites for its internal structure.

Don't take this the wrong way, but... I'd rather this not be the only exoatmospheric fighter-craft in the Escean arsenal. Tell me there's more.

Oh there'll be a few more
A bomber type for one.
There's a heavy unmanned bomber for exoatmospheric. Needs a remake, though.

Interesting, why is it so lightly armed, though? I would imagine that the round size should be increased to 40mm if you actually want to cause some damage. Also, when will we see the strike fighter/bomber variant, the one that can actually damage capital ships? Gotta say, though, fantastic work. I hope your inspiration comes back soon!

Well, bear in mind that it's armed with railguns. The M-71 'Terminator' rifle is a 20mm railgun used by infantry units, which can deliver approximately (assuming I calculated it correctly at the time) 80 tons of kinetic energy on impact because of the velocity. This little fighter has a pair of repeating 20mm Gauss cannon w/1600 rounds. It can cause damage to enemy fighters and enemy ships, and with enough of them attacking a ship's shielding, can deplete it (shields have an energy absorption threshold). The reason for 20mm over 40mm was more ammunition capacity, lighter weight and a more compact weapon and feeding system. 40mm would deliver more energy, but 20mm was considered suitable for its role.
As for fighter/bomber types, I haven't really planned one yet. The Sabre Dart has some internal weapons capability for attacking ground targets. With a quick thought, a fighter/bomber variant may carry a much heavier cannon. The reason for a cannon over something guided is because guided missiles are more complex for operation in space than on the ground, requiring small thrusters to correct course in addition to the main engine (fins won't work). This reduces the explosive yield, unless you amp it up with something more potent. However, missiles also travel slower and are more visible than slugs fired from a railgun/Gauss cannon, making them easier to shoot down.
I may equip a fighter/bomber type with one or two 100mm+ electromagnetic cannons, similar to an Hs 129 style.
Thanks, though ^-^

Well for explosive yield there has been some talk about micro-fusion weapons in real life. The problem is getting the energy to jumpstart the reaction, could your V-non technology do something similar. This would bridge the gap between conventional weapons and full on nukes.

Hmm. I haven't heard of those before. I do have a variation of a fuel-air explosive device (current most powerful explosive after nuclear) that uses liquid vespomide. The problem is, much like nukes, the effects in space are largely minimised to heat and ionised radiation, with little to no shock or blast effects. In the atmosphere, liquid vespomide or vespomide gas explosive devices can hit several kilotons worth of explosive power.

Wait, just came up with another idea. Railguns or coilguns can be used to accelerate a guided projectile to much higher velocity. Since the projectile would already be going as fast as a standard railgun round, igniting the rocket motor would propel it even faster than a standard railgun round. So for a strike fighter maybe include a larger center line gun for lobbing more significant payloads in addition to heavier standard guns?
Also, check out this page, I think it's pretty good inspiration theblackocean.wordpress.com/ca… .

Similar to tank guns firing missiles? I suppose its possible for a cannon with a larger bore.

Endorfinator In reply to MOAB23 [2017-04-09 02:02:51 +0000 UTC]
Sorry for being so late with this. A rocket motor technically provides acceleration, while a rail gun merely gets round up to a certain velocity. Since acceleration is velocity vs. time, and there is no air friction to worry about in space, giving the payload a boost with a rail gun to give it a higher initial velocity will result in a much faster final velocity for the round. So you could get a missile moving faster than a railgun round by giving it the same initial velocity and then the additional boost to the velocity that the rocket's acceleration would add to it.

MOAB23 In reply to Endorfinator [2017-04-09 12:19:23 +0000 UTC]
True, but then the railgun alone could provide more than enough thrust. The projectile could achieve speeds in excess of what a motor could provide, and whilst a motor would add additional velocity to that, I don't think it would be necessary. The motor would take up space and weight that could be used to contain explosives, or added weight to enhance the impact energy.

Reminds me of a Cold War West German proposal to create a VTOL version of the F-104 Starfighter. Nice. However, I see a couple problems with the design. A) the light armament. The fact that it doesn't have any ordnance to deal with ground targets and/or capital ships would limit this to just CAS and interceptor roles (unless that is the intention). B) the fact that you have limited the atmospheric max speed to just Mach 2.5 means that it can't achieve orbital velocity, so it can't return to space once it has entered the atmosphere (at least that is my impression)

This one was designed for intercepting other starfighters or making quick runs on enemy warships. Armament was limited to repeating 20mm rail guns for weight and profile reduction. So long as the enemy ship shielding is depleted or weakened, the rounds will have sufficient velocity to dish some damage into a ship (most ship to ship weapons are kinetic projectiles given the complexity and reduced velocity of a missile for space combat).
Atmoshperic speed was just for combat in atmo, but this is more or less emergency or a desperation use. When it needs to get back into space it really opens up. For ground attack there's dedicated craft (usually drones) or ship to ground cannons

awesome! kinda reminds me of the SR-71 blackbird because of the engines, and specially because of the design and cockpit, brings good memories of Ace Combat, specially Ace Combat 3. a the cameras work in an Ace Combat 3-like COFFIN system perhaps? (just like the one used in the ace combat 5 FALKEN, for example)

One of the AC3 jets - the Delphinius(?) I think it was - did come to mind a bit when I was doing the fuselage. The camera system is a bit like that used (most recently I can think of) in Pacific Rim, where the 'window' is solid and a projector system gives it the appearance of being transparent, with HUD overlays and so on. One of my suit ideas that I'm working on uses a helmet with the same idea. No visor just an armoured faceplate, similar in operation to the Kestrel helmet in Mass Effect.
