6 Lesser-Known Aircraft That Made an Impact in WWII

While iconic planes like the Spitfire, B-17 Flying Fortress, and Messerschmitt Bf 109 are often celebrated, many other aircraft played significant roles in the war effort but remain less recognized. We explore six of these lesser-known aircraft, examining their contributions to the conflict and the reasons why they deserve a place in history.

1. The PZL.37 Łoś (Poland)

The PZL.37 Łoś, a Polish twin-engine medium bomber, was an advanced design for its time, introduced in the late 1930s. It was one of the most modern bombers in Europe before the outbreak of WWII, featuring a sleek, aerodynamic profile and a glass nose that provided excellent visibility for the bombardier. The Łoś was capable of carrying a substantial bomb load for its size and had a respectable top speed, making it a formidable weapon in the early days of the war.

During the German invasion of Poland in 1939, the Łoś was one of the few Polish aircraft capable of effectively engaging the invaders. Despite being heavily outnumbered and facing superior enemy fighters, the Łoś crews carried out several bombing raids against German ground forces and supply lines. Although the Łoś was ultimately overwhelmed by the sheer numbers of the German Luftwaffe, its role in delaying the German advance and its advanced design earned it a place in aviation history.

2. The Fairey Swordfish (United Kingdom)

The Fairey Swordfish, affectionately known as the “Stringbag,” was a British biplane torpedo bomber that played a critical role in several key naval battles during WWII. Despite its outdated appearance and relatively slow speed, the Swordfish was highly effective, especially in the hands of skilled Royal Navy crews. Its design allowed it to take off from short decks, making it ideal for carrier operations, and its ability to carry a variety of weapons, including torpedoes, bombs, and rockets, made it versatile in combat.

One of the most famous actions involving the Swordfish was the attack on the German battleship Bismarck in May 1941. Swordfish torpedo bombers from HMS Ark Royal managed to disable the Bismarck’s steering gear, making it an easy target for the Royal Navy’s surface ships. This action played a significant role in the eventual sinking of the Bismarck. The Swordfish also played a vital role in the Mediterranean, where it attacked and crippled several Italian warships during the Battle of Taranto in 1940, showcasing the effectiveness of carrier-based air power.

3. The Mitsubishi Ki-46 “Dinah” (Japan)

The Mitsubishi Ki-46, known to the Allies as “Dinah,” was a Japanese reconnaissance aircraft that served throughout the Pacific War. Designed for high-speed, long-range missions, the Ki-46 was used primarily for gathering intelligence on enemy positions and movements. Its sleek design and powerful engines allowed it to operate at altitudes and speeds that made it difficult for Allied fighters to intercept, giving the Japanese military a valuable tool for planning and executing their operations.

Although it was primarily a reconnaissance aircraft, the Ki-46 was also adapted for other roles as the war progressed. Some versions were equipped with armament for ground attack missions or modified to carry small bombs. The aircraft’s versatility and reliability made it a favorite among Japanese pilots, and it remained in service until the end of the war, despite the increasing superiority of Allied aircraft.

4. The Bloch MB.150 Series (France)

The Bloch MB.150 series was a group of French fighter aircraft that saw limited service during the early stages of WWII. Developed in the late 1930s, the MB.150 series included several variants, with the MB.152 being the most widely produced. Although it was not as advanced as some of its contemporaries, such as the German Bf 109, the MB.152 was a rugged and capable fighter that performed admirably during the Battle of France in 1940.

French pilots flying the MB.152 faced overwhelming odds against the better-equipped and more numerous German Luftwaffe, yet they managed to score several victories and slow down the German advance. The aircraft’s role in these desperate battles, combined with its solid design, earned it a place in the history of WWII aviation. After the fall of France, a number of MB.152s were used by the Vichy government and later by the Free French Air Force.

5. The Breda Ba.65 (Italy)

The Breda Ba.65 was an Italian ground-attack aircraft that served during the early years of WWII. Designed in the mid-1930s, the Ba.65 was a versatile aircraft capable of carrying bombs, machine guns, and cannons, making it well-suited for close air support missions. It was used extensively during the Spanish Civil War and later in North Africa, where it provided crucial support to Italian ground forces.

Despite its initial success, the Ba.65’s design began to show its age as the war progressed, and it was gradually phased out in favor of more modern aircraft. However, during its time in service, the Ba.65 played a significant role in several key battles, including the Italian invasion of Ethiopia and the early stages of the North African campaign. Its contributions to these campaigns, though often overlooked, were vital to the Italian war effort.

6. The Petlyakov Pe-2 (Soviet Union)

The Petlyakov Pe-2 was a Soviet twin-engine dive bomber that became one of the most successful and widely used aircraft of the Eastern Front. Known for its speed, maneuverability, and versatility, the Pe-2 was employed in various roles, including bombing, reconnaissance, and even as a heavy fighter in some configurations. Its robust design allowed it to withstand significant damage, and its crews appreciated its handling characteristics, especially in low-level attacks.

The Pe-2 played a crucial role in numerous Soviet offensives, including the Battle of Stalingrad and the push towards Berlin. Its ability to deliver precision strikes against enemy positions and supply lines made it a key asset in the Red Army’s efforts to repel and eventually defeat German forces. The Pe-2’s widespread use and effectiveness in combat earned it a lasting legacy in Soviet aviation history.
