Correct Answer: Option B - BRAHMOS uses INS with active radar homing in terminal phase, AKASH uses radar-based command guidance.
BRAHMOS and AKASH are two different missile systems developed for different purposes, with distinct guidance technologies:
BRAHMOS Missile:
It is a supersonic cruise missile jointly developed by India and Russia (hence the name BrahMos - from Brahmaputra and Moscow)
Uses a sophisticated guidance system consisting of:
Inertial Navigation System (INS) for mid-course guidance
Active radar homing in the terminal phase for precision targeting
Can strike targets with high accuracy at speeds of Mach 2.8-3
It's primarily designed as an offensive missile system for precision strikes
AKASH Missile:
It is a medium-range surface-to-air missile (SAM) developed by India
Uses radar-based command guidance system where:
The missile is guided throughout its flight by ground-based radar systems
Commands are sent to the missile for course corrections
Primarily designed for air defense to intercept aerial threats
The other options are incorrect because:
Option A: BRAHMOS does not use optical guidance, and AKASH does not use GPS
Option C: Neither missile relies solely on satellite navigation
Option D: Both missiles are guided, though using different guidance technologies
