Nothing has to be in the same sortie. Node E definitely isn't required since many (including myself) have unlocked with a fast fleet. From what I've read, node D might not be required.

In my case, I had to get 2 perfect LBAS defense, where all enemy planes get shot down. I got the 'white text' three times, but because the enemy 'missed' my base they didn't count. There were two times where I completely obliterated the enemy planes (they all disappeared and didn't take a shot at my LBAS), and after the second one the secret node opened up. This is on hard mode, so I'm not sure if you need 1 or 2 perfect LBAS defense.
