Designation: Ling-Temco-Vought SVC-30 Ox Aerospace Lift Tug

Names and disposition:

  • These tugs were only officially designated by number.

Ship’s Complement:

  • 3 crew


  • Length: 28.4 meters

  • Maximum Lift Mass: 58,000 metric tons.
  • Generator endurance: 12 years.

Electronics Systems:

Radar tracking:

  • Westinghouse APS-145 E/F-band pulse-Doppler forward-looking 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

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.

Weapon Systems:

  • None.

Design Notes:

The United Earth Defense Force (UEDF) Aerospace Command determined the need for a vehicle to assist in launching their space vessels into a low earth orbit for launch to conserve their reaction mass for deep space operations. An auxiliary requirement was for the vehicle to assist in launching their space vessels when a rapid launch situation required more launch facilities than were available at the major space facilities. These requirements led to the development of the SVC-30 Ox space lift tug that allows naval vessels to be launched vertically into low earth orbit while the vessels using the primary launch facilities would launch in a more conventional angled launch profile.

The Ox consists of mostly engine and reaction mass. Five Oxen are capable of lifting a fully loaded Battle-class destroyer to low earth orbit.
