With hindsight, I may have been a bit to quick to describe the Cortium Bomb as useless. If you are trying to destroy a player made base and have access to a nearby equipment terminal e.g. a hacked equip term, or a sundy you can do a fair amount of damage with the cortium bomb if you are prepared to spend the time/mertits on using it multiple times. The quickest way is to take out the silo first, takes about 3 to 4 bombs (obviously don't do this if you are using a hacked equipment term in the base to resupply your bombs as once the silo is gone the terminal is dead) Once the silo is down any pain fields and turrets are are down too so you are free to roam about the base and place more bombs to take out the other key items. In combination with any base destroying weapon of your choice you can take a base out relatively quickly providing nobody turns up to defend it. I'm sure there are quicker ways of achieving this but as a solo take down option it's not too bad.
