The Nagato Explorer has had its weapons improved (at least the Kairyu missile is better against the player, if not in general). The Shinyo missile and Xuanwu-700 were already extremely powerful.

In my current game as the Hercules, I had 6 segments of carbide carapace (2 with +Thermo), a Mammoth 25MW (+20%), and a Titan 440. It took me three attempts to scan the Nagato because I was having trouble staying in range while dodging. I almost died on two of those attempts, despite taking most of the missile hits on my resistant segments. I'm an experienced player and I think my equipment was about as good or better than the player could be expected to have (without significant backtracking) when this mission appears.

I also took enough damage trying to deter the Nagato that I gave up because I knew that failing would allow me to continue. I was using only ED weapons, so the Bastion cannon and Valun bolts were my best options. With better weapons (especially homing missiles) this mission is not so difficult. From the code, it looks like it's supposed to be possible to deter it with hit and run tactics, but I don't think it is.

Suggestions:
- The Nagato shouldn't use missiles against the player on the scanning mission unless the player fires on it.
- The Nagato should wait a few seconds after warning the player, then open fire if the player is still in range.
- Scanning should be easier for ships with poor maneuverability, maybe by increasing the max distance a bit.
- The time between warnings on the deterrence mission should be reduced. At top speed, the Nagato can cross 600 light seconds in 2500 ticks (83 seconds real time), so it's impossible to reach it and damage it three times - 1000 ticks apart - in that time.
