My flight recorder was damaged during the fight in New York so this comes late
Before the assault on Detroit munitions started I was attacked at Alcatraz depot by a strong LSF/SA force (6 fighters) an Ion Storm disrupted the fight and after it calmed down only 2 enemy fighters were in sight.
I managed to destroy one of them and the second one decided to flee.
I let him go and joined the attack on Detroit munitions. Witnessing the destruction of our gunboats I rescued Moriarty and Looter. After a long fight I was the only ship left on our side so I left the battle.
It's important to note that Liberty forces made an efficient use of a repair vessel. This made a big difference especially in later stages of the fight. The repair vessel holds 4000 shield batteries/nanobots, has 100k shield and a better agility than a gunboat. It is therefore impossible to take down for a LF. I advise to focus on such vessels in future fights.
