[36][37] Mid-course guidance is accomplished through inertial navigation system and two-way datalink combined with Global Positioning System/NavIC satellite guidance through digital filtering as fall back to correct accumulated errors and a passive homing head (PHH) seeker which is developed by Defence Electronics Research Laboratory that can detect radio frequency emissions from 100 km away.

[38] Its compact front-end structure is due to the use of monolithic microwave integrated circuit (MMIC) technology for identification of radiation emitting sources.

[39] It uses pre-fragmented warhead with optical proximity fuze and is powered by a dual-pulsed solid rocket motor made by Premier Explosives Limited under technology transfer from DRDO.

[43][44] The dual-pulsed solid rocket motor produces variable thrust within a range of 0.6 to 2 Mach that reduces the overall reaction time while widening the targeting envelope as well as the engagement capability.

[47][48] The feasibility studies were done in 2012–2013 with the aim is to develop a fully indigenous tactical, anti-radiation capable missile for the Indian Air force (IAF) which is comparable to AGM-88E AARGM, MAR-1, Kh-31P and better than Martel or Kh-25MP.

[49] IAF was initially very concerned with the higher weight and shorter range of new missile compare to the western ones due to the use of bulky Russian made radio frequency (RF) seekers.

20 Squadron of IAF which checked the performance of seeker, navigation and control system, structural capability and aerodynamic vibrations while the Drop Flight Trial was completed by December 2016 with the missile released by Sukhoi Su-30MKI at a speed of 0.8 Mach, from 6.5 km altitude.

[54] On 25 January 2019, NGARM was fired from a Sukhoi Su-30MKI over Bay of Bengal off the coast of Odisha that hit the designated target with a high degree of accuracy.

[33] The developmental test proved the performance of seeker, structural integrity of the missile, correct functioning of navigation and control system while validation of aerodynamic capability.

[32] While the crucial sensor technology is yet to be fully mastered by DRDO, the IAF wants fast track development of NGARM due to urgent requirement of newer anti-radiation missile.

[73][74] DRDO is planning to bring further software improvements to handle a larger variety of targets under various operational conditions while developing a separate ground-based variant to be launched from mobile launcher.
