Harb, those aren't part of the ship. UNSC ships use rocket booster systems to give them lift, and they drop away once the ship reaches a specific speed in the atmosphere. The downward facing engines aren't part of the ship, it's more of like the rocket boosters you would see on the Space Shuttle. Specific UNSC ships aren't designed for operation in atmosphere, and the Halcyon happens to be one of them.
