The '''KAB-500Kr'''<ref>{{Cite web|url=https://www.globalsecurity.org/military/world/russia/kab-500.htm|title = KAB-500 (1500) family - Russian Bombs}}</ref><ref>{{cite web|title=KAB-500Kr "drop-and-forget" guided bomb|website=Rosoboronexport|url=http://roe.ru/eng/catalog/aerospace-systems/air-bombs/kab-500kr/}}</ref> (Correctable air bomb - 500&nbsp;kg) is an electro-optical TV-guided [[fire and forget]] bomb developed by the [[Soviet Air Force]] in the 1980s. It remains in service with the [[Commonwealth of Independent States|CIS]] and various export customers.
The KAB-500Kr is analogous to the American [[GBU-15]] weapon. It uses a standard Soviet/Russian FAB-500 [[general-purpose bomb]], with a nominal weight of {{convert|500|kg|lb|abbr=on}}, as a warhead, adding a [[television]] seeker and guidance fins to turn it into a guided, unpowered [[glide bomb]].
The seeker employs a gimballed daylight television imaging sensor under a wide angle glass dome. Unlike the earlier US [[GBU-8|GBU-8 HOBOS]] and [[AGM-65 Maverick]] which employed contrast lock technology, the -Kr series guidance system employs Scene Matching Area Correlation technology more akin to the US Navy DAMASK seeker or [[Tomahawk (missile family)|Tomahawk]] DSMAC. This results in the ability to attack low contrast targets by exploiting the contrast of nearby terrain features or objects.
The bomb is 305&nbsp;cm (10&nbsp;ft) long and weighs {{convert|520|kg|lb|abbr=on}}, of which {{convert|380|kg|lb|abbr=on}} is a hardened, armor-piercing warhead capable of penetrating up to 1.5&nbsp;metres (5&nbsp;ft) of reinforced [[concrete]]. The weapon's seeker can lock onto a target at ranges of up to {{convert|15|to|17|km|mi|abbr=on}}, depending on visibility. The '''KAB-500-OD'''<ref>{{cite web|title=KAB-500-OD "drop-and-forget" guided bomb|website=Rosoboronexport|url=http://roe.ru/eng/catalog/aerospace-systems/air-bombs/kab-500-od/}}</ref> variant is equipped with a fuel-air explosive warhead. The technology of KAB-500Kr is also used for larger bombs, such as [[KAB-1500|KAB-1500Kr]] based on the 1500&nbsp;kg class FAB-1500 iron bomb.<ref>{{cite journal|url=http://www.ausairpower.net/APA-Rus-GBU.html|title=Soviet/Russian Guided Bombs|author=Dr C Kopp|website=ausairpower.net|date=11 August 2009|pages=1|access-date=18 October 2015}}</ref><ref>{{cite web|url=http://eng.ktrv.ru/production_eng/323/518/519/|title=Tactical Missiles Corporation JSC|work=ktrv.ru|access-date=18 October 2015|archive-url=https://web.archive.org/web/20151127144542/http://eng.ktrv.ru/production_eng/323/518/519/|archive-date=27 November 2015|url-status=dead}}</ref>
