Flak 36 88mm Multipurpose Gun
The versatile 88mm cannon was Germany’s main heavy antiaircraft—or “flak”—gun during World War II. When an 88mm projectile exploded at altitude, it sent out jagged metal fragments that tore through nearby aircraft. It also left a characteristic black cloud hanging in the sky.

History & service
The 88mm cannon’s high-velocity fire also made it a deadly antitank gun, and it could be used as conventional artillery against distant ground targets. Other versions equipped heavy tanks and submarines.
The Museum’s 88mm cannon is painted as a typical weapon used in Europe during the strategic bombing campaign. The rings around the barrel represent aircraft shot down by the gun crew.

The occasional direct flak hit caused devastating damage. Amazingly, five of the ten crewmembers on this B-17 bailed out before it fell out of control.
Aircraft change the battlefield
In the First World War, aircraft became valuable because they could see beyond the front line. Reconnaissance and artillery observation affected decisions on the ground. Once that information mattered, opposing forces had reason to attack the aircraft gathering it. Fighters, defensive armament, and increasingly specialized missions developed around this contest over observation and freedom of movement.
The aircraft were fragile by later standards, but their crews worked inside a rapidly expanding military system. Training, maintenance, replacement aircraft, photography, communications, and weather reporting supported each sortie. Improvements in engines and armament changed tactics, while the pressures of combat exposed weaknesses that might have taken much longer to discover in peacetime.
Personal stories should be read alongside those systems. A uniform or a named aircraft connects the war to an individual, but the individual depended on many others and operated under constraints that skill could not eliminate. Aircraft from opposing sides show how designers answered similar problems in different ways. The later military collections in Dayton and at Udvar-Hazy reveal what endured: the need to gather information, protect friendly forces, move people and supplies, and coordinate action across distance. The scale changed enormously; the relationship between an aircraft's design and the job it had to perform remained fundamental.
