Long Day

Long Day is the sixth campaign mission in Ace Combat 7: Skies Unknown. As a new member of Spare Squadron, the player must assist regular Osean forces in neutralizing an Erusean desert base.

Briefing
''Your mission is to atone for your crimes by attracting the enemy's attention. First, I want you to head from the base to the desert region of Roca Roja to the northwest. And then second you'll attack the large Erusean base there. We've been unable to verify that base's ability to deal with fighters. You will attack and provoke the enemy into revealing their AA strategy. Get them to fire at you as much as you can. That way we can confirm where they're firing from. Then, it's a case of sending in our regular force to clean them out. For this mission, we've prepared a frontline base that can be used for ammo replenishment and aircraft repairs. However, this is not for you guys. Only the regular force has permission to use it. Even if you run out of ammo, don't forget that you're just decoys. You stay out there as targets for the enemy.''

Objectives
There are three distinct sectors in the Erusean base: one to the north, one to the south, and one to the northwest. The player's main objective is to earn a total of 17,000 points. The player has to travel between all three bases to earn enough points to complete the mission. Some parts of the base also feature tunnels that the player can fly into to destroy more targets.

A Return Line is located to the east, but whether the player is physically prevented from using it or not is currently unknown.

After the player earns 17,000 points, a large squadron of MQ-99s will spawn and begin to attack. No further details on the mission are known at this point.

S Rank
The S rank requirements are not currently known.
