Halo array build time from the ark?

Does anyone know how long it would take the ark to build a halo array from start to finish?

Well 04 was destroyed on September 22nd and the events on the ark were around November 17th to December 11th. (Not sure when the exact date for when the battle for 00 took place.) When we see the new 04 being built on the Ark it was about 2 or so months after the original ring was destroyed and the ring wasn’t complete yet, probably about halfway finished. So assuming it was halfway done it would take about a total of 4 or 5 months. That’s my guess.

raid on 04B took place on December 11th. so yeah in a few months 04B was 10,000 kilometers (6,210 miles) in diameter an semi operational. so like he said not long at all less than half a year. it would be nice to know the production times for the Arks (wink wink 343)
