The only case in history of a battle between an American airship and a German submarine
American K-class airships, created for the US Navy by the GoodYear aircraft manufacturing company, 134 units entered service with the American Army in 1938. These airships were of soft construction and were equipped with sonars, radars and other equipment. They were widely used in patrol and anti-submarine operations.
The German submarine U134 was launched in May 1941 in Bremen. To combat air targets, this submarine had an 88-mm SK C/35 anti-aircraft gun and a 37-mm SK C/30 anti-aircraft gun.
On July 17, 1943, the US airship K74 took off from the Richmond Naval Air Station on a routine anti-submarine patrol. The crew of ten was led by Lieutenant Nelson Grylls. Suddenly, the radars detected an object, which, when approaching, turned out to be a German submarine moving on the surface at a speed of up to 18 knots.
The aircraft commander decided to launch an attack. The airship approached the target from a height of 76 meters at an angle of 30 degrees so that the bombs could hit the long side of the submarine. The speed was increased to 55 knots. The behavior of the submarine indicated that the presence of the airship had not been detected.
The airship opened fire from a 50-caliber machine gun, as a result of which one of the rapid submersion tanks was damaged. The submarine returned fire from an anti-aircraft gun. Since the submarine was already directly under the airship, it was impossible to continue machine-gun fire and the aircraft commander decided to start bombing. However, none of the bombs detached from the external suspension pylons.
As a result of the attack, one of the airship's engines caught fire from the submarine's anti-aircraft gun, and the elevators also stopped working. In addition, the shell of the airship was pierced, which is why it began to slowly sink downward with its rear end.
After the airship fell into the water, its crew left the flooded gondola and swam away using life jackets. One of the crew members died due to a shark attack, and the rest made it safely to shore.
