You will have to destroy or capture a planet closer to the planet with the OMD. Then you could put Raid Starships in an Assault Transport and destroy the OMD. You would probably lose 1 Raid Starships.
Another option is to go around the OMD planet.
Go around isn't an option since it was placed at a solar system next door to Murdoch on X layout map. It block the path to one of the AI's homeworld. I know I can kill it. However, I also would like to capture it intact for the same reason placement is great against AI.
I already took a strike force through and lost a champion (really? first shot was champion?!) and a single mark 1 neinzul CC. The fleet has a merc neinzul enclave which is at the moment deep behind the OMD. I already sneaked my replacement champion past the OMD but enclave/Neinzul CC can't cloak so.
I can't keep them behind the line either because they will just spawn reprisal waves after reprisal waves (neinzul drone do contribute to those apparently). Repairing will not be an issue since I have a MSD with them.
I don't think it is a good idea for me to pop AI command station at Murdoch just yet.
Wow I think I will roll back... I just lost my entire neinzul fleet on a solar system with dark vengeance/gravitric command station/mark 3 shield and four spire mk 3 shield guard post on the only exit. On the other hand good news look like I have relative plenty of adam asteroids I may considering using jumpship. Is loading easy fast to do?
I am bit worried about 20 second to "expire" timer on same mark as jumpship itself as that is new to me.
Edit: I, after I rollback to a save game before that deathtrap, manage to get my fleet back home while evading a Hunter/Killer with moderate losses. (2 mk 1 enclave, 1 mk 3 enclave, and 1 mk 2 Neinzul CC) But for long-term strikes I am thinking using some spire jumpship, last time I used them they were "loss some hp each time they jumped" model. Anything I need to know about them? On the plus side I manage to neuter most of that branch's solar systems except for the deathtrap gravitric with shield place and other hard to break mark four systems.
