The mass of SDB I bombs is only 110 kilograms (of which 90 kg is an explosive charge). It can be hung on peculiar adapters, 4 under 1 910-kilogram hanger point or stronger. For example, the F-16 has 5 specified suspension points (four underwings and 1 underback), and the FA-50 3 (two underwings, 1 underback).
