What I mean was that you can change the name of the existing female officer (new officer).
For the destroying Taiho 2, there will be these after effect :
1. The opposition will blame Margenrot and Nimm for the plan to disturb the WOLF 359 Alien. Their argument is based on "IF you don't disturb them, then Taiho 2 won't coming to Earth". Diana Nimm will go to jail, or at least to military court as she was the one who planned it.
2. Ewan Ahmed will become the Hero of Earth. You should give him and the other participants in combat with badge / star
3. Your NCN Public Relation officer will announce the birth of a new generation warship that will ensure the safety of Solar System. So the next gen starship will get a lot of publication like it will become your hero ship / flagship. Ewan Ahmed will goes to TV more than attend his duty as a captain / commodore.
4. The wormhole to Wolf 359 will be shut down / barricade with the strongest NCN Warships to tell people that Earth is really really safe.
Well, officially, the government will consider Wolf 359 as a restricted space where no one can go there. But you still can do something to cheat this. Like conducting a secret operation, etc. Or, there will a hardliner politician will emerge (just like Hitler) who will declare war against the alien and strike Wolf 359 again in the future.
