The &#039;&#039;&#039;High Speed Low Drag&#039;&#039;&#039; (&#039;&#039;&#039;HSLD&#039;&#039;&#039;) bomb is a family of new generation short range [[Aerial bomb|air-dropped]] [[precision-guided munition]] that is currently being developed by India&#039;s [[Defence Research and Development Organisation]] (DRDO). This [[general-purpose bomb]] is made for the [[Indian Air Force]] (IAF) and can be used against the destruction of strategic high value enemy infrastructure from stand-off distances.&amp;lt;ref&amp;gt;{{Cite book|last=Christopher|first=S|title=DRDO Newsletter|publisher=Defence Scientific Information and Documentation Centre|year=2017|location=Delhi|pages=5}}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;{{Cite web|title=&#039;Glide bombs&#039; the latest weapon in IAF&#039;s arsenal|url=https://www.rediff.com/news/report/glide-bombs-the-latest-weapon-in-iafs-arsenal/20130602.htm|access-date=2020-09-23|website=Rediff|language=en}}&amp;lt;/ref&amp;gt; HSLD is comparable to [[Mark 80]] series of bombs used by [[United States Air Force]] (USAF).&lt;br /&gt;

The [[Armament Research and Development Establishment]] (ARDE),&amp;lt;ref&amp;gt;{{Cite web|date=2017-12-18|title=Glide Bomb SAAW: Guided weapon&#039;s success proof of DRDO prowess in developing indigenous capability|url=https://www.financialexpress.com/industry/glide-bomb-saaw-guided-weapons-success-proof-of-drdo-prowess-in-developing-indigenous-capability/978209/|access-date=2020-09-22|website=The Financial Express|language=en-US}}&amp;lt;/ref&amp;gt; [[Pune]] is the primary agency that started developing HSLD with the help from other DRDO laboratories to upgrade the conventional free fall [[Unguided bomb|unguided ordnance]] used by the Indian Air force (IAF) fighter pilots while [[Ordnance Factory Board]] (OFB) is the lead production agency. The development started with the aim to replace the older generation imported general purpose bombs that impose huge [[Drag (physics)|drag]] loss on [[fighter aircraft]] used by the IAF. The HSLD bomb is specially designed to productively use the higher speed of up to [[Mach number|Mach]] 1.1 and wider flight envelope of newer generation [[NATO]] and Russian origin as well as Indian made aircraft. [[High Energy Materials Research Laboratory]] (HEMRL) developed the [[Conventional weapon|conventional]] type warhead that features [[Blast wave|blast]], [[Fragmentation (weaponry)|fragmentation]] and [[shaped charge]] for [[bunker buster]] role which uses Dentex as [[primary explosive]] for HSLD 450 and [[Torpex]]-4B mixed with [[RDX]] that act as [[explosive booster]] for HSLD 500.&amp;lt;ref name=&amp;quot;P.

HSLD can be launched from variety of aircraft that are under IAF inventory like [[Dassault Mirage 2000]], [[Mikoyan MiG-29]], [[SEPECAT Jaguar]], [[Sukhoi Su-30MKI]] and [[HAL Tejas]]. IAF has already successfully tested PGHSLD 500 from Su-30MKI platform.&amp;lt;ref&amp;gt;{{Cite web|url=https://www.defenseworld.net/news/20565/DRDO_Tests_500_Kg_General_Purpose_Bomb_From_Su_30MKI_Aircraft|title=DRDO Tests 500 Kg General Purpose Bomb From Su-30MKI Aircraft|website=www.defenseworld.net|access-date=2020-03-23}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Production facility ===&lt;br /&gt;
[[Ministry of Defence (India)|Ministry of Defence]] (MoD) gave green light to start mass production of 500 kg general purpose bomb by [[Munitions India Limited]] at Ordnance Factory Khamaria. On 17 January 2022 under the guidance of a team from HEMRL and ARDE, the first two bombs were carefully filled with primary and secondary warhead fillings. Each GPB carries 10,300 steel shells of 15 mm diameter. Each shell can target an area of upto 50 m from place of [[detonation]].&amp;lt;ref&amp;gt;{{Cite web|date=11 January 2022|title=DNA Explainer: The bomb that can destroy any airport in Pakistan|url=https://www.dnaindia.com/india/report-dna-explainer-gp-bomb-that-can-destroy-any-airport-in-pakistan-drdo-jabalpur-ordnance-factory-sukhoi-30-jaguar-2927949|url-status=live|access-date=2022-01-18|website=DNA India|language=en}}&amp;lt;/ref&amp;gt;  &lt;br /&gt;
&lt;br /&gt;
== Trials ==&lt;br /&gt;
Two successful developmental trials were conducted in 2013 to prove the capability of the munition with all development related works to be completed by 2014.&amp;lt;ref&amp;gt;{{Cite news|title=India developing guided bombs for fighters|work=The Economic Times|url=https://economictimes.indiatimes.com/news/politics-and-nation/india-developing-guided-bombs-for-fighters/articleshow/20391950.cms|access-date=2020-09-22}}&amp;lt;/ref&amp;gt; From 22 May 2017, ARDE and IAF conducted a series of carriage as well as carriage release trials (CRT) for High Speed Low Drag 500&amp;amp;nbsp;kg class unit, with both general purpose and precision guided variant at [[Pokhran]] range, [[Rajasthan]]. In initial carriage trial, the bomb carried [[sensor]]s, [[telemetry]] and [[data logger]] while during the separate CRT session, [[satellite guidance]] units were added which flew on Su-30MKI from [[Jodhpur Air Force Station|Jodhpur Air force Station]]. The bomb touched the carriage limit of 1041&amp;amp;nbsp;km/h (0.85 [[Mach number|mach]]) at 150 metre [[altitude]] on Su-30MKI that performed a 6.5 [[Gravitational acceleration|g]] full roll manoeuvre during the first GPB 500 trial while the PGHSLD 500 separation was carried out from an altitude of 5&amp;amp;nbsp;km at a speed of 900&amp;amp;nbsp;km/h (0.73 mach). Both bombs cleared the flight envelope and completed all the required parameters without any form of mechanical damage during the high speed release from the aircraft. The trials were conducted with the help of [[Hindustan Aeronautics Limited]] (HAL), [[Indian Air Force Test Pilot School]] and [[Centre for Military Airworthiness and Certification]] (CEMILAC).&amp;lt;ref&amp;gt;{{Cite web|url=https://www.eastcoastdaily.in/2017/09/09/india-successfully-tests-500-kg-indigenous-hsld-bomb.html|title=India successfully tests 500 kg Indigenous HSLD Bomb|website=East Coast Daily English|date=9 September 2017|language=en-US|access-date=2020-03-23}}&amp;lt;/ref&amp;gt;&lt;br /&gt;

== Description ==&lt;br /&gt;
It is a liquid cooled AESA radar featuring quad band modules that can be stacked to form a larger unit. This allows the manufacturer to scale the radar to be used in larger aircraft. There are plan to create a larger scalable design to be used in [[India]]&#039;s fifth-generation HAL AMCA jet fighter.&amp;lt;ref name=&amp;quot;uttamaerojournal&amp;quot;&amp;gt;{{cite web|title=Uttam AESA radar: Everything you need to know|url=http://www.aerojournalindia.com/enews/?p=2914|access-date=14 January 2019|publisher=Aero Journal India}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The radar development began in 2012 and its full-scale model was displayed at the 2017 [[Aero India]]  air show and aviation exhibition.&amp;lt;ref&amp;gt;{{cite news|title=Uttam AESA radar ready for induction in Tejas MK1A|url=https://defenceview.in/uttam-aesa-radar-ready-for-induction-in-tejas-mk1a/}}&amp;lt;/ref&amp;gt; A fully functional AESA radar prototype was unveiled at Aero India 2019, the prototype was mounted inside the glass nose of a HAL Tejas prototype.&amp;lt;ref name=&amp;quot;uttamaero19&amp;quot;&amp;gt;{{cite web|title=India Displays Locally-made AESA Radar for Tejas Jet at Aero India 2019|url=https://www.defenseworld.net/news/24318/India_Displays_Locally_made_AESA_Radar_for_Tejas_Jet_at_Aero_India_2019#.Xp_nUZrhWV4|access-date=20 February 2019|publisher=DefenseWorld}}&amp;lt;/ref&amp;gt; As of 2021, three units were in various phases of testing,. The Uttam radar has completed 230 hours of airborne testing onboard two Tejas fighter jets (LSP2 and LSP3) and on an executive jet; presumed to be DRDO&#039;s [[Dornier 228]] &amp;quot;Nabhratna&amp;quot; used as a flying test bed by LRDE.&amp;lt;ref&amp;gt;{{cite news|title=Exclusive: Why desi Uttam AESA radar is a game-changer|url=https://guardingindia.com/exclusive/exclusive-why-desi-uttam-aesa-radar-is-a-game-changer/}}&amp;lt;/ref&amp;gt; Once fully validated and certified, it is planned is to introduce the radar in later batches of Tejas Mark 1A aircraft.&amp;lt;ref name=&amp;quot;uttam-mk1a&amp;quot; /&amp;gt;&amp;lt;ref&amp;gt;{{cite web|title=HAL cuts its profit on Tejas Mark 1A deal by 50%, fighter jets to take to sky by 2022|url=https://theprint.in/theprint-essential/hal-cuts-its-profit-on-tejas-mark-1a-deal-by-50-fighter-jets-to-take-to-sky-by-2022/383730/|access-date=19 March 2020|publisher=The Print}}&amp;lt;/ref&amp;gt; The Uttam radar will be used with DRDO&#039;s Unified [[Electronic Warfare]] suite.&amp;lt;ref&amp;gt;{{cite web|title=Single Engine Fighter Cancellation Provides An Opening For Tejas MK-2|url=http://delhidefencereview.com/2018/02/26/single-engine-fighter-cancellation-provides-an-opening-for-tejas-mk-2/|access-date=26 February 2018|publisher=Delhi Defence Review}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
During Aero India 2021, there was a licensing agreements for [[technology transfer]] from DRDO to [[Hindustan Aeronautics Limited]] for manufacturing and integration of the Uttam in the Mark 1A variant of the HAL Tejas.&amp;lt;ref&amp;gt;{{cite web|date=5 February 2021|title=DRDO hands over Licensing Agreements for Transfer of Technology for 14 technologies to 20 industries|url=https://pib.gov.in/PressReleasePage.aspx?PRID=1695630|publisher=PIB}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
[[Indian Air Force Test Pilot School]] will start final demonstration trial of Uttam AESA radar from December 2021 and if successful will be sent for serial production. As per Project director D Seshagiri of [[Electronics and Radar Development Establishment]] (LRDE), Uttam AESA radar is 95% indigenous, with only one imported subsystem. The radar has the capacity to track 50 targets at a range greater than 100 km while engaging 4 targets simultaneously. All 83 [[HAL_Tejas#Tejas_Mark_1A|Tejas Mark 1A]] and [[HAL AMCA|AMCA]] will come equipped with this radar. Uttam AESA radar will also be installed into upgraded [[Sukhoi Su-30MKI]] and [[Mikoyan MiG-29K]] currently in use as front line platform of [[Indian Air Force]] and [[Indian Navy]]. [[Hindustan Aeronautics Limited]] is the lead integrator and [[Bharat Electronics]] is major supplier of subsystems. LRDE already completed 250 hours of performance testing on two Tejas fighters as well as [[Hawker 800]] executive jet. National Flight Testing Centre had evaluated the radar and cleared it after performance tests. The integration problem of [[Astra (missile)|Astra BVRAAM]] due to older generation of radars will also be solved by Uttam.&amp;lt;ref name=&amp;quot;:0&amp;quot;&amp;gt;{{Cite web|last=Gupta|first=Shishir|date=2021-12-08|title=India develops AESA radar to make IAF fighters more lethal|url=https://www.hindustantimes.com/india-news/iaf-to-showcase-use-of-indigenous-aesa-radar-101638924141445.html|url-status=live|access-date=2021-12-08|website=Hindustan Times|language=en}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
