Designation: Lockheed SF-2 Hunter Space Fighter

I. Dimensions:

II. Service History:

• SF-2A: Experimental platform used by the UNDF Spacy from 2006 until 2007.
• SF-2B: Served with the RDF Spacy from 2007 until 2009.

III. Type:

• One man space fighter gunship.

IV. Propulsion:

• 3 x Rocketdyne DRoE-2 reaction engine, two in the tail section, one halfway on the ventral hull, providing 80 kN thrust each.
• Assorted maneuvering thrusters.
• 3 x protoculture cell for power generation.

V. Performance:

• Range (space) : delta-v limit of 3.1 kps.
• Powercell endurance : full function for 120 hours.
• Design-g limits : 1.5 g maximum acceleration.

VI. Electronics:

Radar System:

• Hughes AWG-20S X-band pulse-Doppler radar, providing long-range detection and tracking of targets at all altitudes, as well as extensive search, attack, and space navigation modes.

Optical tracking:

• Thomson DOS-1900 multi-band digital camera system, for medium range spherical UV, infra-red imaging and optical band detection and tracking,
• Thomson LT-3 multi-frequency laser ranger and designator,
• Zeiss TS-1D long range telescopic array for visible/IR spectrum.

Tactical Electronic Warfare System (TEWS):

• Elettronica Radar Warning Receiver (RWR),
• OlDelft Infra-red Warning Receiver (IRWR),
• Westinghouse ALQ-200 active radar jammer,
• Chaff dispenser,
• Flares,
• Active missile jammers.

VII. Armament:

• 2 x Mauser RöV-20 laser cannon (head/turret). Each barrel is capable of firing 6000 pulses per minute, peak power 6 megawatts per gun.
• 2 x Euromissile StarStrike specialized space missiles. Warhead is equivalent to the one on the Stiletto missile, and the StarStrike utilizes 'burn and drift' tactics. Delta-v capacity 2 kps. Missiles are ejected sideways from a launch port in the nose.

VIII. Armor:

The skin of the Hunter is composed of an advanced titanium-steel alloy. The armor stops all small arms fire, provides good protection against heavier infantry weapons, such as a 12.7mm machinegun round, and fair resistance to light mecha-mounted weaponry, such as the Zentraedi 22.3mm HE autocannon round. The internal consumable supplies are enough to last for two days.

IX. Development:

The SF-2 Hunter space fighter was the first step in Terran space mecha development. As such, while this craft is rather obscure, it has an impressive listing of descendants. The Hunter was, as first envisioned, a cockpit with two engines and fuel tanks attached, armed with two turret mounted lasers. After the first design stage, a large nose with some missiles and more rocket fuel was bolted on, but under the thrustline of the craft, and a third engine was needed to balance the Hunter. The Hunter was a design of a period marked by gargantuan leaps of technology, and as such, almost obsolete even before it entered service.

The SF-2A series of space mecha had a production run of 24 craft during 2 years, and is mostly known for featuring in off-Earth films of the period. The improved SF-2B series was built in a run of 144, and spent the full time of its commission (two years) stationed at the L-5 factory that built the Oberth-class destroyers and ARMD carriers. Even before the Zentraedi arrival and the start of the first Robotech War, the Hunters had been withdrawn from service. Their most celebrated accomplishment is that they taught the UN Spacy the minimal skills needed to operate extra-atmospheric combat mecha.
