From Defence Forum India:


  The Sabre Warrior drone is 46 feet long, with a 36-foot wingspan,
  capable of taking off with 30,000 pounds of load using a 22,000-pound
  trust afterburning turbofan engine. It has two modular payload
  sections, which can be changed by soldiers in the field. Each bay can
  handle one 2,000 pound or two AIM-120 AMRAAM missiles or 10 smart
  bombs or sensors, or even fuel for extended range missions—”even
  while this thing is air refuelable.
  
  Its twin nose can also hold multiple sensors, which are
  interchangeable. And it is designed so there could be a version with a
  cockpit, so they can send man version as an on-the-scene controller,
  overlooking over the unmanned versions.



The Raptor F-22 is a 5th generation fighter, Sabre Warrior the 6th.
Requirements worked with DARPA and USAF.
It has been considered for the UK Future Offensive Air System (FOAS), cancelled in 2005.
