Fieseler Fi 167 Built for Carrier “Graf Zeppelin”

The Fieseler Fi 167 was a German biplane that served both as a torpedo bomber and reconnaissance aircraft.

For many years, the “Torpedo Bomber” was a significant threat to all surface ships. Its origins trace back to the period just before World War I (1914-1918), and by World War II (1939-1945), it had evolved into a highly refined weapon.

In 1937, the German Air Ministry issued a requirement for a new torpedo bomber to be deployed from the planned German Navy aircraft carrier, “Graf Zeppelin”. In response, Fieseler developed the “Fi 167”, a design featuring a two-seat open-air cockpit, biplane wings, and a fixed undercarriage. A total of fourteen Fi 167 aircraft were constructed between 1936 and 1942.

The Air Ministry’s specifications demanded an all-metal biplane capable of speeds up to 185 miles per hour and an operational range exceeding 600 miles.

Despite being somewhat outdated for the era, the biplane wing design was chosen for its excellent lift properties, crucial for carrier operations, and for offering greater control to the pilot. Additionally, the aircraft was required to be adaptable for general dive bombing missions against moving warships, beyond its primary role of carrying torpedoes.

Fieseler’s design competed against another contender from Arado, the Ar 195, of which three were built. These were the only two manufacturers approached for the project.

In 1938, the Arado design was selected, leading to the construction of prototypes V1 and V2 for comprehensive testing. This phase was followed by an order for twelve pre-production models under the designation “Fi 167 A0”.

Development

This aircraft was conceived in response to a specific requirement set forth by the German Kriegsmarine (Navy) for a new class of aircraft carrier-based operations. The Graf Zeppelin-class aircraft carriers, which were under construction at the time, needed a versatile aircraft capable of performing both torpedo bombing and reconnaissance duties.

Fieseler, already renowned for the successful Fi 156 Storch, undertook the project. The design of the Fi 167 was a notable departure from the emerging trend of monoplane construction in military aviation.

Instead, Fieseler opted for a biplane design, which, though considered somewhat outdated by contemporary standards, offered several advantages crucial for carrier-based operations.

The Fi 167 competed against the Arado Ar 195 for the Navy’s contract, but ultimately the project’s continuation was affected by the cancellation of the Graf Zeppelin carrier.

The biplane configuration of the Fi 167 provided it with excellent low-speed handling characteristics and short takeoff and landing capabilities. These features were essential for operating on the relatively short flight decks of aircraft carriers.

Additionally, the biplane design allowed for a more robust and durable structure, which was necessary for withstanding the rigors of naval operations, including resistance to corrosion from the marine environment.

In terms of its construction, the Fi 167 was primarily built with metal, a choice that lent it both durability and reliability. It was powered by a single Daimler-Benz DB 601B engine, a reliable and well-regarded powerplant of the era, which provided it with a balance of speed and range adequate for both bombing and reconnaissance missions.

The Fi 167’s armament and payload capabilities were also a key aspect of its design. It was equipped to carry torpedoes for anti-ship missions, as well as a range of bombs for conventional bombing roles. For reconnaissance tasks, it featured the necessary equipment for long-range observation and intelligence gathering.

Despite its promising design, the Fi 167 faced a significant obstacle. The cancellation of the Graf Zeppelin-class aircraft carriers meant that the primary operational context for which the Fi 167 was specifically designed no longer existed. This shift in strategic priorities led to a curtailment in the production and deployment of the aircraft.

Performance of Fieseler Fi 167

The Fi 167 was powered by a Daimler-Benz DB 601B engine, a reliable powerplant that was widely used in German aircraft. This engine provided the Fi 167 with a good balance of speed and power, making it suitable for both its intended torpedo bombing and reconnaissance roles. The biplane’s maximum speed was modest compared to contemporary monoplanes, but it was sufficient for the tasks it was designed for.

One of the most notable performance characteristics of the Fi 167 was its exceptional short takeoff and landing (STOL) capability. This feature was crucial for operations from the deck of an aircraft carrier, where space was limited. The aircraft’s biplane design, with a larger wing area relative to its size, allowed for greater lift at lower speeds, which was essential for STOL performance.

In terms of operational capabilities, the Fi 167 was versatile. For torpedo bombing missions, it could carry a single heavy torpedo, a load significant enough to pose a threat to enemy shipping. For conventional bombing roles, it had the capacity to carry a variety of bombs, making it adaptable to different types of bombing missions.

As a reconnaissance aircraft, the Fi 167 was equipped with the necessary equipment for observation and intelligence gathering. Its range and endurance made it suitable for extended reconnaissance missions, an essential aspect of naval warfare where gathering intelligence on enemy movements and positions was crucial.

Fieseler Fi 167 Maneuverability

The Fi 167’s handling and maneuverability were other important aspects of its design. The biplane configuration provided a high degree of control and stability, which was beneficial in the often turbulent conditions encountered at sea.

The Fi 167’s maximum speed was around 185 miles per hour, with an operational range of over 600 miles.

This stability, combined with the aircraft’s good low-speed handling, made it relatively easy to fly, an important consideration for pilots operating in the challenging environment of an aircraft carrier.

Durability and reliability were also key features of the Fi 167, reflecting the demands of naval operations. The aircraft’s all-metal construction ensured it could withstand the harsh conditions of maritime environments, including resistance to corrosion from saltwater. This robustness was essential for an aircraft expected to operate from the decks of carriers and in the challenging conditions of the open sea.

Fieseler Fi 167 Going Operational

The operational history of the Fieseler Fi 167, while brief and circumscribed by the evolving priorities of World War II, presents an interesting case of an aircraft designed for a specific purpose that ultimately never came to fruition.

Initially conceived for operation from the Graf Zeppelin-class aircraft carriers, the Fi 167 was destined to play a significant role in the Kriegsmarine’s nascent naval aviation capabilities.

A total of fourteen Fi 167 aircraft were built between 1936 and 1942.

However, the strategic focus of the German military shifted significantly during the war. The emphasis on submarine warfare and the intensifying campaigns on the Eastern Front led to the de-prioritization and eventual abandonment of the Graf Zeppelin-class carriers.

This shift effectively left the Fi 167 without its primary operational platform, altering its intended role in the German military strategy.

Despite this setback, the small number of Fi 167s produced were not relegated to obsolescence. They found a secondary life in land-based roles, primarily relegated to training and coastal reconnaissance duties. Some were stationed in areas like the Netherlands and the Balkans, where they were utilized for various auxiliary tasks.

These included roles such as towing training gliders and conducting short-range maritime patrols. In these capacities, the Fi 167’s design strengths, particularly its STOL capabilities and rugged construction, were still of significant value, even though the aircraft was not employed in the role for which it was originally designed.

The Fieseler Fi 167’s legacy is largely defined by its status as a well-designed aircraft that never fully realized its potential due to changes in the strategic priorities of the German military. It stands as an example of the rapid pace of military technology development during the period, and how quickly certain technologies or platforms could become obsolete or redundant.
