That manoeuvrability coupled with the twin Ryza batteries is going to make for a nasty combat ship. The range suffers a bit, but the Empyrean Mantle should help them close distances anyway. A flexible ship, but I don't know that I would call it a warship. Should it ever conduct operations in conjuction with the Blessed Enterprise, they would make for a fright'ning pair.
The Miloslav drive is always a good choice, and should always be recommended in my opinion.
