  • Elettronica Radar Warning Receiver (RWR)
  • OlDelft Infra-red Warning Warning Receiver (IRWR)
  • Selenia Sky Warrior active/passive sensor jammers
  • Chaff dispenser
  • Flares.

VII. Armament.




  • 1 x Hughes HRC-25 25mm five barrel rotary cannon firing SLAP (Saboted Light Armor Piercing) or HEI (High Explosive Incendiary) 25mm rounds at 6000 rounds per minute. Internal ammunition supply of 21mm rounds.


  • 2 x Colt E-19B 4.5 MJ lasers in the nose. Both lasers can fire 60 times per minute.

4 hardpoints (2 under each engine nacelle) can each carry:

  • 1 x combined IIR and active radar guided, 75 km range, Mach 3 Python missile,
  • or 1 x Carapace missile container, containing three missile tubes, each of which can contain two Diamondback or Lightning missiles, or four Hammerhead missiles.

VIII. Armor.

The skin of the Falcon is composed of an advanced titanium-steel alloy. The skin stops all small arms fire, provides fair protection against heavier infantry weapons, such as a 12.7mm machinegun round, and poor resistance to light mecha-mounted weaponry, such as the Zentraedi 22.3mm HE autocannon round.

The Falcon provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for eight hours maximum.

IX. Development.

In 2014, the UN Spacy was in need of a new conventional fighter to supplement its Veritech fighter squadrons. For the important task of defending the Earth’s population centers proper, the UN Spacy needed high speed fighter-interceptor, capable of fighting the Gnerl Fighter Pods on their own terms. The call was put out for a beam-cannon armed, fusion turbine powered fighter interceptor. Four candidates were submitted: Northrop’s YF-110 Falcon, Rockwell Bell’s YF-204 Lightning III (a non-variable variant of the VF-4 Lighting III Veritech fighter), Lockheed’s YF-117 Drake (a non-space capable version of their YFA-117, which had already failed to win the contract for an aerospace fighter against the FA-101 Vulture) and McDonnel-Douglas’ YF-15 Super Eagle (a fusion turbine powered update of the positively geriatric F-15 Eagle). Northrop’s design won, being the leat compromised design, and the second least expensive after the YF-15, which was kind of a non-starter in the first place.

The Falcon II uses a flying body shape with minimal wings to support hypersonic speeds for its interceptor role. The small wings are used more for maneuvering and stabilization than for lift. As its Interceptor and Fighter Pod destroyer objectives required a high thrust/mass ratio, the aft end of the flying body was one large engine bay, housing two of the fusion turbines and one plasma shock expansion engine, which was used for sustained hypersonic flight and combat accelerations. The final two fusion turbines were housed in nacelles under the body. The Falcon II had a fairly standard electronics suite and its armament consisted out of two internal laser cannons with a high rate of fire, and four hardpoints for missiles or missile pods. The Falcon II was built from the advanced titanium alloys that gave the airplane a good protection against at least spall and shell fragments. Later, the F-110G introduced radar absorbing material (RAM), enhancing its already small radar cross section.

This fighter was used in various variants by the Civil Defense Flying Corps for the air defense role, the Naval Corps for the fleet defense role and the Tactical Air Force for air defense and as a tactical fighter bomber. It served all the way through till the Invid invasion. Because of the nature of its units, and the target choice of the F-206C Falcon II Fighter Aircraft 1Masters for most of the Second Robotech War, these planes saw only limited action. During the Invid invasion, most Falcons were destroyed in battle against the Invid. Most remaining ones were destroyed on orders of the Invid Occupation Authorities.
