Miller UH-460 Canary

The HMH-460 Canary, often called the HMH, Canary, or Chopper (Being the only military helicopter of its time), was one of the only helicopters built in the 26th century. The predecessor to the Canary, the HMH-450, was first built in 2489. Production Ended for it in in 2510, and was retired by 2518, though about one hundred were reactivated in 2528 for the war effort. They proved to be very effective as a cheap alternative to the newer Pelican dropship for ferrying Colonial Militants and Army servicemen from one location to another. However, as more and more battles involved ferrying soldiers from space, which the HMH-450 wasn't capable of, it was put out of service in the military almost completely, though it was still used through 2539 as a non-combat transport and was used through 2600 as a civilian craft. In 2546, the first HMH-460 was built and was used in training excersises involving non-lethal outcomes. By 2548, the HMH was put into mass production, with over three thousand built by 2550. After 2550, however, the HMH-460's production stopped when the planet which produced all 460's was glassed. It was still used, though, through the end of the Human-Covenant War and the Great Civil War.

Variants
All Canaries are split into multiple classes, listed below.

HMH/T-460 (Transport)
The variant making up most of the class. It has no standard arnament, but can have one manned gun on either side of the cargo bay. These have a troop capacity of eight.

HMH/A-460 (Assault)
This variant is intended for attacking enemy forces, especially air units. Armed with ANVIL-II Air-to-Surface Missiles and either a dual .30 or single .50 caliber chin gun, it is finished up with slightly thicker armor. The pods carrying extra fuel on either side are sometimes replaced with heavy rockets or bombs.

HMH/C-460 (Civilian)
As the name implies, the Civilian variant is intended for use by research, expeditionary, or private owners. Most systems, includng all weapons, are removed from the vehicle. This model is also used by the UNSC to quickly ferry people across bases and some transport businesses on war-torn colonies use the HMH/C to travel long distances, for a price, until highways are rebuilt.
