According to the Twitter account of Defence and Strategic Studies, PNS Himmat fired an indigenously developed Harba naval cruise missile, which is a surface-to-surface anti-ship missile with land-attack capability,” If the Harba ASCM is a variant of the Babur, Defence and Strategic Studies speculates, then it would essentially be a long-range sea-skimming ASCM. Like the C-802 ASCM, the Harba ASCM would likely rely on an inertial navigation system (INS)-based mid-course guidance system coupled with a terminal-stage active-homing seeker. It is not known what kind of active seeker the Harba ASCM is using, though for anti-ship warfare (AShW) active radar-homing (ARH) is a widespread solution. However, imaging infrared (IIR) could be an alternative, especially involving cases where strong electronic warfare (EW) and electronic countermeasures (ECM) jamming is expected (which can interfere or scuttle an ARH seeker).
The key aspect of the Harba is its potential range – 450 km or 700 km (depending on whether it is derived from the Babur 3 or Babur Version 2, respectively). (…)
