Weaponry questions This is a list of recently added questions about weaponry. What is the main reason to use nuclear reactor on a submarine?It needs no oxygen. Nuclear reactor requires no oxygen for combustion and emits no exhaust gas. It gives the submarine the ability to operate submerged at high speeds, for unlimited periods, dependent only on the endurance of its crew. Nuclear power revolutionized the submarine, finally making it a true "underwater" vessel, rather than a "submersible" craft.Created by: Riho Ishiivery hard 29% it needs no oxygenit needs no oxygen1546it needs no frequent refuellingit needs no frequent refuelling2020it is silentit is silent1479it is smallit is small141nuclear energy riddles » Which country mass-produced speedboats packed with explosives as a weapon during WW2?Japan.
