Q

Launch events sequence

A
  • Gunner attaches CLU to the LTA
  • Forward end cap removed
  • Target acquired, either with optics or the Thermal Imaging (TI) sight
  • Gunner activates missile seeker by pulling left trigger on CLU
  • After approximately 9.5 secs the missile seeker cools down
  • Flight software data is downloaded and missile becomes operational
  • Once missile is operational infrared imagery from seeker is viewed by gunner through CLU
  • Tracker software data downloaded from CLU to missile
  • Gunner then positions track gates to specify the target portion of the seeker image
  • Target maybe engaged either by DA or OTA
  • On completion of target lock on gunner depresses CLU fire trigger
  • Depression of trigger fires missile restraint pin squib to fire
  • On successful completion of pre launch tests software issues command to fire launch motor
  • Overpressure from LM opens aft membrane and propels missile forward
  • Forward motion fractures forward seal and severs umbilical cable and gas line interfaces Missile continues along LTA until missile wings and fins clear the LTA
  • Once clear of LTA and confirmation of correct launch, missile software issues command to ignite FM
  • Warhead is armed following safe separation distance from operator determined by CESAF module
  • Seeker and tracker software continues to track target to impact without intervention by gunner
