Thorluis2 Posted February 12, 2024 Posted February 12, 2024 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

Thorluis2 Posted February 13, 2024 Author Posted February 13, 2024 I have found documentation showing that they are the 2 gps antennas https://www.usna.edu/Training/_files/documents/References/2C MQS References/NAVEDTRA 14014A Ch. 9 Aircraft Ordnance.pdf 1
Thorluis2 Posted February 17, 2024 Author Posted February 17, 2024 (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, 2024 by Thorluis2
Falconeer Posted February 17, 2024 Posted February 17, 2024 (edited) No, they get the info from the HOB sensors (Height Of Burst) Edited February 17, 2024 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 Afghanistan F-15E Strike Eagle Kola Peninsula Mirage 2000C AJS-37 Viggen JF-17 Thunder F-14 Tomcat F-4E Phantom
Thorluis2 Posted February 18, 2024 Author Posted February 18, 2024 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
