Production notes
The Harpoon nuclear missile was first-mentioned in a piece of concept art for the frigate Andraste in a concept pieace done by Isaac Hannaford for Halo 3. Ultimately, the ship (and weapon) was not featured in-game, but the design was faithfully recreated for inclusion in Halo: Reach. The Harpoon is mentioned in the concept art, labelling several silos present on the upper decks of the ship. The name was later fully-canonised in the Halo Encyclopedia (2022 edition).

The Harpoon shares its name with a modern-day anti-ship missile.
