Context: DRDO recently conducted the flight test of ABHYAS – High-speed Expendable Aerial Target (HEAT) from a test range in Odisha.

• The configuration of ABHYAS is designed on an in-line small gas turbine engine and it uses indigenously developed MEMS based navigation system.
• ‘Abhyas’ is designed for autonomous flying with the help of an autopilot.
• A Luneburg lens in the nose cone improves the radar cross-section of the target for weapons practice.
• It also has an acoustic miss distance indicator (AMDI) to indicate the missed distance.
