Thorluis2 Posted February 12 Share Posted February 12 What is the purpose of the two domes on the gbu-48? I am assuming they are for radio fuse like the paveway 4 but I am unsurenull Paveway 4 for reference Link to comment Share on other sites More sharing options...

Thorluis2 Posted February 17 Author Share Posted February 17 (edited) But they seem to still have airburst option, although it might be based off target distance using gps rather than radar altimeter. https://defense-update.com/20171219_gbu-48.html https://www.defenceprocurementinternational.com/Content/Profiles/junghans-defence/bombfuze-fbm21-datasheet.pdf http://proceedings.ndia.org/5560/thursday/session_iv-a/pinel.pdf Edited February 17 by Thorluis2 Link to comment Share on other sites More sharing options...
Falconeer Posted February 17 Share Posted February 17 (edited) No, they get the info from the HOB sensors (Height Of Burst) Edited February 17 by Falconeer Planes: Choppers: Maps: Flaming Cliffs 3 Black Shark 2 Syria A-10C Tank killer 2 Black Shark 3 Persian Gulf F/A18C Hornet AH-64 Apache Mariana's F-16C Viper F-15E Strike Eagle Mirage 2000C AJS-37 Viggen JF-17 Thunder F-14 Tomcat Link to comment Share on other sites More sharing options...
Thorluis2 Posted February 18 Author Share Posted February 18 18 hours ago, Falconeer said: No, they get the info from the HOB sensors (Height Of Burst) The gbu 48 has no Hight of burst senor. If you are referring to the paveway 4, they do have a HOB senor they likely use in such a manner Link to comment Share on other sites More sharing options...
