Designation: Lockheed SF-3A Lancer II Space Fighter

I. Dimensions:

  • Total Length: 13.2 metersLockheed SF-3A Lancer II Space Fighter 5
  • Total Height: 2.65 meters (w/ radar)
  • Dry weight: 9.3 metric tons
  • Max takeoff weight: 15.7 metric tons

II. Service History:

  • Served with the UN Spacy from 2008 until 2017.

III. Type:

  • One man space fighter/interceptor.

IV. Propulsion:

  • 2 x Rocketdyne DRoE-4 reaction engine in tail section, providing 750 kN thrust each at max efficiency (60 second burn), 1128 kN at max power setting (5 second burn),
  • Multiple high-maneuverability Vernier nozzles located in the rear of the craft engine,
  • OTEC Protoculture-cell Energizer powered by eight protoculture cell for power generation.

V. Performance:

  • Range (space): Delta-v limit of 7.0 kps.
  • Powercell endurance: Full function for 140 hours.
  • Design-g limits: 1.9 g max acceleration.
  • Thrust-to-weight ratio, empty: (60-second burn) 16.11:1; (5-second burn) 24.21:1
  • Thrust-to-weight ratio, max T-O: (60-second burn) 9.75:1; (5-second burn) 14.65:1

VI. Electronics:

Radar System:

  • Hughes AWG-20 X-band pulse-Doppler radar, providing long-range detection and tracking of targets at all altitudes, as well as extensive surface search, attack, navigation, and mapping 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 Hughes long-range charged particle beam cannon; rated at 750 MJ each.
  • 2 x MDS-L-12 missile launcher each carrying one Hughes StarStrike specialized space missiles with half kiloton class thermonuclear warhead. Range and speed n/a, delta-v capacity 2 kps. Missiles are ejected sideways from 2 launch ports in front of the Lockheed SF-3A Lancer II Space Fighter 12lower engine section. Latter, the MDS-L-12 was adapted to carry three conventional short range (2.5 kps in space) infra-red imager or passive radar homing HMM-01 120mm Starburst missiles..

VIII. Armor:

The skin of the Lancer II 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 ungainly Lancer II space fighter made up the majority of the manned airgroup (for lack of a better word) of the early Niven-class ARMDs, and a significant fraction of the original aircraft complement of the SDF-1 Macross. Since this craft was a space fighter only, no attention needed to be given to aerodynamic shaping, and the result was made up of, rear to front, two engines (one on top, the other on the bottom), a fuel tank, the power plant, pilot compartment and computer systems in a rectangular housing with a magazine for two missiles in the lower hull, and then the main weapon system. Since the main task of the fighter was anti-mecha warfare, the armament was designed to take out mecha at long range with the main cannons, and to eliminate any mecha that broke through the main gun’s perimeter with the nuclear StarStrike missiles. The main cannons were charged particle beam guns with a truly massive yield of 750MJ. A large sensor antenna was placed on top of the main section. The Lancer II was used by the Armor ships as well as by the SDF-1, although this system was only used once by the larger ship, during the Zentraedi Holocaust. The few Lancer fighters that survived that battle were re-assigned to the remaining ARMDs, and were soon replaced by Rockwell Textron’s FA-101 Vulture aerospace fighter.
