The grade II and grade III bombs were made of separate nose cone, main body and aft cone parts welded together; the mechanical strength of the grade II bombs was approximately 80% of the grade I, in the grade III bombs, the mechanical strength on impact was ca. 40% of that of grade I bombs; these bombs were therefore meant to be used only on targets where instantaneous detonation on impact was necessary.
217:) I bombs, the nose cone and the bomb body were forged out of a single piece of high quality alloyed steel or the nose was welded to the body; these bombs were of the highest mechanical strength and they were meant to be used against robust targets necessitating penetration before detonation of the bomb, or as

Bombs filled with
Trialen 105 were to be used especially as water bombs/depth charges against enemy shipping and submarines, however the Trialen bombs could be used to a great effect against land targets as well. The bomb was held in place by suspension lugs, which could be fitted either to the nose

After forging the body or welding the nose cone and the aft cone to the body, this was loaded with the exploder tube, the fuze pocket and then the main filling. Thereafter the body was sealed with the base plate, and the four-finned tail was attached. With an overall weight of 250 kg
