Learning objectives

1. Know how to use HAD
2. Know how to use WPN page
   1. Know when and how to use POS (EOM, PB, RUK)
   2. Know when and how to use HAS

POS

POS will always slave to a selected steerpoint; no steerpoint means no shot in POS mode

• Manually select steerpoints or threat steers in HSD or jump to pre-planned target steerpoints using UFC
• Alternately, set mark points as references to radars to use POS mode
• In POS, you can use EOM (very fine control – you know exactly where the target is and it is on the current steerpoint), PB (wider control – the target is close to a threat steer point), or RUK (extremely wide control – the target is around your current position and will lock on to the first thing it sees). You still need a steerpoint, remember.
• RUK is LOAL, HAS is LOBL.
• RUK, PB, EOM are all three POS modes and all POS modes are steerpoint-directed in azimuth. The difference is in end game seeker activity and assumed range only. EOM and PB assume range = range to steerpoint. RUK assumes range = maximum.
  • EOM = point
  • PB = area
  • RUK = lane
• RUK is for painting a long, wide stripe of ground with HARM coverage. PB is for a floodlight on an area. EOM is a laser pointer.

HAS

HARM as a Sensor
