The Captive Flight Trial–1 (CFT–1) of DRDO ARM was completed on April/May 2016 by [[No. 20 Squadron IAF|No. 20 Squadron of IAF]] which checked the performance of seeker, [[navigation]] and [[control system]], structural capability and [[Aerodynamics|aerodynamic]] vibrations while the Drop Flight Trial (DFT) was completed by December 2016 with the missile released by [[Sukhoi Su-30MKI]] at a speed of 0.8 [[Mach number|Mach]], from 6.5&amp;amp;nbsp;km altitude.&amp;lt;ref&amp;gt;{{Cite web|url=https://www.indiastrategic.in/2016/12/31/year-end-review-achievements-of-ministry-of-defence/|title=Year End Review: Achievements of Ministry of Defence – India Strategic|language=en-US|access-date=2020-02-18}}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{Cite web|url=https://www.defenseworld.net/news/15378/|title=DRDO To Begin Flight Trials Of Anti-Radiation Missile In 2016|website=www.defenseworld.net|access-date=2020-02-17}}&amp;lt;/ref&amp;gt; Further carriage flight test was carried out to check mechanical/electrical integration as well as software interfacing of the missile before the maiden flight on 18 January 2018, where the missile was successfully flight tested for the first time on parametres such as auto-launch sequence, store separation, control guidance, aerodynamics, thermal batteries, airframe and propulsion without a seeker which were all proven successful.&amp;lt;ref name=&amp;quot;:7&amp;quot; /&amp;gt; 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.&amp;lt;ref&amp;gt;{{cite news |last1=Pandit |first1=Rajat |title=India tests new anti-radiation missile to destroy enemy radars |url=https://timesofindia.indiatimes.com/india/india-tests-new-anti-radiation-missile-to-destroy-enemy-radars/articleshow/67676064.cms |work=The Times of India |date=24 January 2019}}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{Cite web|url=https://www.aninews.in/news/science/odisha-drdo-successfully-test-fires-lr-sam20190124153102/|title=India testfires indigenous enemy radar-buster missile|website=www.aninews.in|language=en|access-date=2020-02-18}}&amp;lt;/ref&amp;gt; The missile achieved an accuracy within 10 m [[Circular error probable|CEP]] covering a range of 100&amp;amp;nbsp;km.&amp;lt;ref name=&amp;quot;:3&amp;quot; /&amp;gt; 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.&amp;lt;ref name=&amp;quot;:6&amp;quot; /&amp;gt; The missile can strike at distances double the intended range depending upon the altitude.

===Induction===&lt;br /&gt;
According to report, the plan is to make the missile a part of the Air Force by 2022 after conducting six to seven more tests. The missile’s passive homing head can detect, classify and engage targets over a wide band of frequencies as programmed.&amp;lt;ref&amp;gt;{{cite web|url=https://keralakaumudi.com/en/news/mobile/news.php?id=423410&amp;amp;u|title=Rudram missile to be inducted into service by 2022: top officials|work=Kerala Kaumudi}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Future development ===&lt;br /&gt;
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.&amp;lt;ref name=&amp;quot;:1&amp;quot; /&amp;gt;&amp;lt;ref name=&amp;quot;:2&amp;quot; /&amp;gt;&lt;br /&gt;
