This will add a fifth “mission thread” to the four missions, which are: air superiority, suppression and destruction of enemy air defenses, close air support, and strategic attack of key targets.
Winter stated that the Long-Range Anti-Ship Missile (LRASM) will not be included in this Block IV configuration.
