III. Service History:

  • Served with the UEDF Military Airlift Corps (MAC) from 2024 until the Invid invasion.

IV. Propulsion:

  • 3 P&W F127 main fusion engines providing 294.2 kN of thrust each.
  • 2 P&W F126 secondary fusion engines providing 93.2 kN of thrust each.
  • 10 Rocketdyne DRaE-4b ram/scramjet/reaction engine in underwing pods (5 per wing pod), total thrust 87 kN each for efficient high-altitude flight.
  • Power-source: 4 x SCR-2P Miniaturized Protoculture-cell energizer

Fuel Capacity:

  • 32 standard canisters of protoculture,
  • 49.6 liter D20 reactant for fusion engines.

V. Performance:

  • Maximum speed: 3210 kph @ 15,000 meters (Mach 2.6)
  • Service Ceiling: 26,000 meters
  • Powercell endurance: 250 hours continuous use
  • Maximum Take-off Weight: 450 metric tons

VI. Electronics:

Radar tracking:

  • AlliedSignal APS-140 X-band multi-mode pulse-Doppler forward-looking weather and terrain mapping radar.
  • APX-110 IFF secondary surveillance transponder

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

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.

VII. Armament:

  • None.

VIII. Armor:

The skin of the Phoenix is composed of treated steel plate. 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 Phoenix 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 two days maximum.

SC-37 Phoenix Cargo Aerospacecraft 2IX. Development:

The Phoenix was designed by Lockheed to be able to transport entire units rapidly to far away locations. This aircraft built upon their research for the aerospace plane and high speed civil transport conducted in the 1980s and 90s. The United Earth Defense Force (UEDF) needed a platform that could quickly transport their limited troops anywhere in the world to deal Zentraedi uprisings or a resurgent Soviet Union. The designers decided that using protoculture cell and fusion reactor technology could drastically reduce the weight of fuel needed for a transport. This allowed for an incredible carrying capacity for this aircraft. This massive aircraft can be used for airborne insertions of an entire squadron of ground-based mecha into hostile landing zones. Due to its size and poor maneuverability, the Phoenix relies on its massive engines to provide sufficient speed to escape any threat.

SC-37 Phoenix Cargo Aerospacecraft 3Due to its high speed and poor maneuverability, no tanker, gunship or electronic warfare version of this transport were ever developed. At least one Phoenix was adopted by the Tactical Space Corps and had its wings reinforced and hardpoints added for use in launching booster-equipped satellites and shuttles. A bomber variant known as the SB-37 Starfire II was also under development at the beginning of the Second Robotech War. The Starfire II would have been an “arsenal aircraft” carrying hundreds of tons of conventional, nuclear or cruise munitions. Though three prototypes were built, the war shifted the UEDF’s focus and the project never came to fruition.
