AF-6 Hornet 8VI. Electronics:

While the electronics suites of these vehicles differed with their respective dates of operational service, all electronics were regularly updated, and during the Second Robotech War the following standard was in use:

Radar tracking:

  • Westinghouse APG-145 X-band pulse-Doppler omni-directional radar.

Optical tracking:

  • Phillips AllView II multi-band omni-directional digital camera system, for medium range all attitude infra-red imaging, optical and ultra-violet band detection and tracking
  • Thomson LT-5 multi-frequency laser ranger and designator.

Tactical Electronic Warfare System (TEWS):

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

10dVII. Armament:

  • 4 x Colt E-19 4.5MJ laser cannons are mounted around the missile ‘stinger’. These cannons can fire up to 40 times/minute.
  • 2 x MHMR4, one rack on either side of the upper main fuselage. An armored cover flips up to reveal four 190x540mm short range Hammerhead missiles. Each launcher contains two reloads, for a total of 24 missiles.
  • 10c1 x CBM-300 ‘Stinger’ Cluster Bomb Missile. This large (5×1.3 meter) missile has a range of 4km and a payload of 300 self-guiding cluster bombs with a range of 500 meters. The ‘footprint’ of this ordnance is an area 1km in diameter.

VIII. Armor:

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

The Tivar II 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 one day maximum.

IX. Development:

The AA-1 Tivar II was specially designed by the United Earth Defense Force’s (UEDF’s) Tactical Space Corps to attack massed targets. Introduced in 2021, the Tivar II was a very strange craft, with bat-like wings and a single missile sticking out from under the front of the craft. The total appearance was much like a hornet, the fighter overall resembling one in attack posture, with the large missile resembling the stinger. Because of its odd shape, the Tivar II was not capable of landing on a planetary surface. The cluster missile was designed to be used against Zentraedi mecha concentrations, and the sub-munitions each were powerful and accurate enough to destroy a Zentraedi Battlepod. Combat simulations indicated that against a lightly-armored opponent like the Zentraedi, a single cluster missile could score over one hundred mobility kills. In addition to the heavy missile, the Tivar II carried four laser cannons around the stinger for dogfights, as well as two Hammerhead multi-missile racks.

10This armament was the raison d’être of the Tivar II. It was never meant to be an actual space-supremacy fighter, rather it was a platform from which to deliver the CBM-300. When acting in a more conventional fighter role, the Tivar II was rather slow and vulnerable. During war-games, it was also found that by dispersing ones forces an enemy could effectively negate the effectiveness of the Tivar II’s main weapon system.

The Tivar II never saw much service, considering its limited numbers and peacetime deployment, and with the arrival of the Robotech Masters and their heavily armored Bioroids, against whom the Tivar II’s missile’s submunitions were less effective, the Tivar II was finally withdrawn from service in 2031.
