&lt;br /&gt;
==History==&lt;br /&gt;
The Squadron was formed on 16 October 1965,&amp;lt;ref name=BRakshak&amp;gt;{{cite web|title=Squadrons and Helicopter Units|url=http://www.bharat-rakshak.com/IAF/Units/Squadrons/292-Squadrons.html|publisher=Bharat Rakshak|access-date=26 July 2022}}&amp;lt;/ref&amp;gt; as an Air Defence unit, under Wing Commander E.R. Fernandes. It was to be equipped with [[Folland Gnat]]s, but relied on Gnats borrowed from [[No. 2 Squadron IAF|2 Squadron]], and [[No. 18 Squadron IAF|18 Squadron]], until 14 May 1966, when it got its first batch of Gnats. In December 1968, the squadron was also allotted the role of Ground-Attack.&amp;lt;ref name=IAF.nic&amp;gt;{{cite web|title=No 21 Squadron(Ankush)|url=http://indianairforce.nic.in/show_unit.php?ch=16|publisher=Official Website of the Indian Air Force|access-date=26 July 2022}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===1971 Operations===&lt;br /&gt;
====Task====&lt;br /&gt;
During the [[Indo-Pakistan War of 1971]], the task of Air Defence of the Barmer Sector was allotted to the squadron, for which the squadron operated from Uttarlai with eight Gnats, with three more Gnats and pilots at Amritsar.  The squadron was commanded by Wing Commander S.S. Malik, who was also designated Air Defence Commander of the sector. The Station Commander at Uttarlai was Wing Commander V.K. Murthy.&amp;lt;ref name=&amp;quot;IAF.nic&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The men of the squadron were initially housed in tents. Subsequently, they were housed in the underground ATC. As word spread that Pakistani Commandos were seen in the sand, the men had to take turns doing night patrols. Soldiers could only have a bath every alternate day, and had six hundred rounds of ammunition with which they had to hunt goose for food.&amp;lt;ref name=&amp;quot;IAF.nic&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
====Operations====&lt;br /&gt;
On 3 December, a Pakistani [[Martin B-57 Canberra|Canberra]], dropped eight bombs on the runway, making it unsuitable for use. However using civilian labour, the squadron cleared out the parallel taxi track. Thereafter only the track was used for take-off and landing. During the war, the squadron flew a total of 109 sorties, most of which were Combat Air patrols.&amp;lt;ref name=&amp;quot;IAF.nic&amp;quot;/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The first bit of action it saw was on the morning of 10 December. Squadron Leader Kale, and Flying Officer P. Ajit were flying a CAP, when they spotted two [[F-104 Starfighter]]s. they engaged the planes, but failed to do damage, and had their runway bombed.
