MX-52

An anti-fighter turret fired swarm missile, even if all of them hit, they shouldn't be any problem to a fighter or bomber.

Most of the time, a target enters a turret's field of fire before entering this missile's view cone, so the entire swarm typically fails to track. Increasing the missile's view cone to about/at least 180 degrees makes it an effective supplement to flak turrets when fending off a heavy bomber attack.
