How Did Battleships Aim Their Guns During World War II?

During World War II, battleships firing on land relied on precision techniques to accurately target their guns. This involved the use of aircraft, ground troops, and specialized personnel known as artillery spotters. The process was intricate and required careful coordination to avoid causing friendly fire and to maximize the effectiveness of the artillery fires.

Role of Artillery Spotters and Forward Observers

Artillery spotters were crucial to the operation of battleships firing on land. They were skilled personnel stationed either on the ground or in aircraft, overseeing the aiming of the big guns. Ground-based spotters were often placed at a safe distance from incoming fire but close enough to the target to provide accurate feedback. Their primary responsibility was to radio in the precise target location and make necessary adjustments to ensure the shells landed in the correct spot. This role was not without its dangers, as a single mistake could result in friendly fire, with tragic consequences.

Use of Aircraft and Float Planes

One of the most common methods during World War II was the use of aircraft, such as spotter planes. These aircraft would fly over the target area, providing real-time updates to the battleships. The planes were equipped with radios to relay information back to the ships. Aircraft played a key role in coordinating fire, especially in complex terrain where visual observation was difficult.

Post-War Developments

Following World War II, some battleships had their catapults and cranes removed to accommodate the use of helicopters. For instance, HMS Vanguard, the last battleship built, used helicopters for similar purposes. Meanwhile, the American battleship New Jersey, which served during the Vietnam War, still retained a crane for raising and lowering boats. By the 1980s, when the last Iowa-class battleships were active, they had their cranes removed and replaced with drones for target spotting. These drones provided valuable information to mechanical computers, which then aimed the guns with precision.

The Impact of Shells and Artillery

Artillery was known for its powerful impact, often covering large areas with a massive number of shells. With a compass divided into 6000 parts, it was possible to direct fire with great accuracy. The quantity and precision of artillery shells meant that land targets could be hit with great effectiveness. However, the processes involved were far from straightforward. Most of the time, shells were fired over the heads of observers, who often never got to witness the battleships that fired them.

A Personal Account

A personal story further illustrates the risks and responsibilities of artillery spotting. My friend, who held this position, had to maintain a precarious balance between proximity to the target and safety. He was often tasked with directing corrections to ensure accurate fire. A wrong move could mean directing fire onto friendly positions or failing to eliminate an enemy threat. The complexity of the job was evident in the coordinated efforts to maximize the impact of artillery support.

Modern Innovations

In the 1980s, battleships like the Iowa-class utilized drones for target spotting, feeding data into mechanical computers to automate the aiming process. This technological advancement was a significant step forward in the precision and efficiency of naval artillery. Today, the principles remain the same, yet the tools and techniques have evolved to enhance accuracy and reduce risks.
