"Use torpedo charges for the explosives," said Shire.
Tijani nodded in agreement. With the same volume and weight, the mixed explosive made from TNT and hexanitrodiphenylamine has 7% more power, meaning a higher chance of destroying submarines.
"This thing aims for simplicity and cost-effectiveness," Shire continued, "We can currently use a time fuse. After it's produced, test its sinking speed. Then estimate the submarine's sinking speed to determine the depth…"
"Then we can drop the bomb in the direction or position where the submarine might escape," Tijani said excitedly, "It doesn't even need to directly hit; exploding near the submarine might still succeed!"
Shire was quite surprised; this guy actually knew these things?
This was Shire underestimating Tijani. The principle was the same as that of torpedoes.
