Answer: Quick to Adjust (“Vergil”) was “interrogated” by ONI for information related to what is now referred to as the Excession at Voi, but were unable to acquire any actionable intelligence before the High Prophet of Truth arrived with the Forerunner Keyship. The Huragok recovered aboard the Gettysburg met a variety of fates in the waning days of the War; the survivors were put to work on the Infinity project and at high-priority Forerunner research sites such as Trevelyan.

Given that:
-Huragok are Forerunner creations.
-Both Forerunner and Forerunner creations show up like lights on a Christmas tree in Covenant Luminaries.
-Covenant are under standing orders to kill Huragok in danger of defecting to the UNSC.
∧When the Covenant invaded Earth, any research facility with Huragok on staff would have been carpet-bombed or glassed until that little Huragok widget on the Luminary display winked out.

Glad to see this confirmed. I've been peddling this theory on the Waypoint forums, and keep getting told that the UNSC would have somehow secured the Huragok. Or that the Covenant don't use Luminaries anymore.

Q: Are Shortsword, Vulture, Longsword, Sabre and Falcon aircraft still in service as of 2557? (Excluding Spirit of Fire)

A: The Longsword and Falcon remain in active UNSC service with the Navy/Air Force and Army, respectively. Without the exigencies of the Covenant War requiring every combat-worthy airframe be pressed into service, the remaining Shortsword inventory was either transferred to UNSC Air Force reserve units or scrapped, depending on their condition.

Interestingly, I thought they were referring to the deleted Halo Wars unit when they mentioned the Falcon.
Anyhow, I wouldn't mind seeing Shortswords in-game, either providing air support or on the tarmac. It's a neat-looking aircraft.

The Sabre was an experimental aerospace fighter and never saw mass production, though it remains in service at ONI facilities in the Sol system (and elsewhere, unofficially); it’s enduring legacy can be seen in the upgrade packages fitted to the contemporary Broadsword strike fighters and Longsword interceptors.

Grammar and spelling aside, swap "Sabre" and "Broadsword", and I'll be as pleased as punch.

The Vulture had largely disappeared from UNSC inventories due to irreplaceable combat losses by 2545, but Materials Group is currently evaluating the possibility of restarting production (albeit with the benefit of improved materials and incorporation of new technologies).

More railguns, no lasers, and an appearance in Halo Wars 2 please.
