History of the BB-1 Sukhoi Su-2!

The BB-1, later renamed the Sukhoi Su-2, was a Soviet single-engine light bomber and reconnaissance aircraft designed by Pavel Sukhoi in 1937, serving during the early stages of World War II. Known for its mixed construction (wooden fuselage, metal wings), the BB-1 (Blizhniy Bombardirovschik-short-range bomber) was designed for speed but became quickly obsolete due to poor armor and light armament.

Developed from the "Ivanov" competition in 1936, a requirement for a high-speed multipurpose aircraft to conduct reconnaissance and ground attacks. Designed by Pavel Sukhoi while under the Tupolev OKB. The prototype, ANT-51, first flew on August 25, 1937. It was produced in large numbers with a mixed wood/metal structure due to material shortages.

Crew 2 pilot and gunner, Primarily equipped with Shvetsov M-62 or Tumansky M-87 radial engines. Typically armed with 4-6 7.62mm ShKAS machine guns and capable of carrying up to 400-600 kg of bombs or RS-82/RS-132 rockets. Used for scouting and short-range bombing in the initial phase of the Soviet-German war.

While fast for its time, it lacked armor and was highly vulnerable to enemy fighters, leading to heavy losses and its transition to training or reconnaissance roles. was the first aircraft designed by Pavel Sukhoi and was produced in 893 units. The designation "BB-1" stands for Blizhniy Bombardirovschik (short-range bomber).

History of the Polikarpov I-15 Chaika Seagull!

The Polikarpov I-15 "Chaika" (Seagull) was a Soviet fighter developed in 1933-1934 by N.N. Polikarpov. Known for its distinct "gull-type" upper wing and high maneuverability, the 1-15 was a premier biplane fighter of its time, featuring a mix of wood and metal construction, open cockpit, and fixed landing gear. It saw extensive combat, famously in the Spanish Civil War (1936-1939).

Designed to improve upon the I-5, the first prototype (TsKB-3) flew in October 1934, piloted by V.P.
Chkalov. The initial "WR" variants were often fitted with the 715-hp American Wright Cyclone SGR-1820-F-3 engine. Later production models used the licensed Soviet-built M-25 engine. The I-15 was used by Republican forces in Spain (nicknamed Chato), where it outperformed early German and Italian rivals. Approximately 384 were built between 1934-1936 in the USSR, with further production in Spain.

It had a top speed of roughly 367 km/h, exceptional turning capabilities, and was armed with four 7.62mm PV-1 machine guns. The original gull-wing design (I-15) was followed by the revised I-15bis (straight top wing) in 1937, and later the retractable-gear I-153. On November 21, 1935, test pilot V.K. Kokkinaki set an unofficial world altitude record of 14,575 meters in a modified I-15. The aircraft was gradually outclassed by faster monoplane fighters by 1938-1939, but it remained in service in various theaters early in World War II.

History of the Messerschmitt Me 163B Komet!

The Messerschmitt Me 163B Komet was a revolutionary WWII German rocket-powered interceptor, designed by Alexander Lippisch as the first operational tailless aircraft. Entering service in 1944, it was the only rocket fighter to see combat, capable of exceeding 1,000 km/h (620 mph) and rapidly climbing to 30,000 feet in under 3 minutes, though it was plagued by extreme fuel volatility and short range.

Specifically designed for "point-defense," the Komet was meant to quickly climb and attack Allied bombers over Germany. The Me 163B Wings of Glory Wiki was the first manned aircraft to exceed 1,000 km/h in level flight, with test pilot Heini Dittmar reaching 1,130 km/h (700 mph) in 1944. It used the Walter HWK 509A-1 rocket motor, powered by highly volatile fuel components (T-Stoff and Z-Stoff) that could explode or dissolve pilots upon contact, earning it the nickname "Devil's Broomstick".

Pilots had only about 4-7 minutes of powered flight time, often gliding back to base, or, due to releasing their landing gear at takeoff, landing on a skid. Only 279-300+ units were delivered, with the sole operational unit, Jagdgeschwader 400(JG 400). Scoring roughly 9-16 kills against 14 losses. Several were captured by Allied forces, including the US and UK, for evaluation, with one now on display at the Smithsonian National Air and Space Museum.

History of the RN Francesco Caracciolo!

The RN Francesco Caracciolo was the lead ship of a planned class of four Italian super-dreadnought battleships ordered in 1914, designed to be fast (28 knots) with eight 381 mm (15-inch) guns. Construction halted during World War I to prioritize smaller vessels. Launched in 1920, the unfinished ship was scrapped by 1926 after failing to find a viable conversion role.

Designed as Italy's first super-dreadnoughts to rival ships like the British Queen Elizabeth class, with a planned 31,000-ton displacement. Laid down on October 16, 1914, at the Castellammare di Stabia shipyard. Work stopped in March 1916 due to steel shortages and the need for destroyers and submarines. Three other ships-Cristoforo Colombo, Marcantonio Colonna, and Francesco Morosini-were ordered in 1915 but were cancelled and scrapped on the slipway.

Launched on May 12, 1920, to clear the slipway.
Efforts to complete her as a battleship or convert her into an aircraft carrier failed due to lack of funds, leading to her sale to a private firm for conversion into a cargo ship, which was also abandoned. The hull was ultimately sold for scrap in 1926. The 381 mm guns intended for the Caracciolo class were repurposed for use as land-based coastal defense guns. Planned max speed was 28 knots (52 km/h; 32 mph). The ship was roughly 212 meters long overall.

History of the Leopard A1A1 L/44!

The Leopard A1A1 (L/44) was a 1980s West German prototype, often referred to as a precursor to the Leopard 1A6, designed to upgrade the Leopard 1A1A1 with the powerful Rheinmetall 120mm L/44 smoothbore gun. It featured a modified turret to accommodate the new gun and improved armor, but the project was canceled in 1987 as the Leopard 2 was already in widespread service and cost-effective upgrades were available.

Developed as a private venture by Rheinmetall to enhance the firepower of the aging Leopard 1 fleet, aiming to bring Leopard 2-level, third-generation, 120mm firepower to the lighter Leopard 1 chassis. The prototype featured a modified turret mantlet, increased armor, and was later equipped with the EMES 18 fire control system from the Leopard 1A5. The project took place in the early to mid-1980s, with multiple prototypes, but was ultimately abandoned in 1987.

The project was considered redundant because the 120mm-armed Leopard 2 was already in service, and upgrading old Leopards was seen as too costly when the 1A5 package was available. While based on the A1A1, this specific testbed variant carried the 120mm L/44, which is significantly more powerful, boasting 50% more penetration than the standard 105mm gun. It never entered large-scale production or active service, remaining a prototype in the development of 1A5 and 1A6 variants. The vehicle is well-known in modern media, such as War Thunder, as a premium, high-firepower, low-armor, and highly mobile sniper tank.

History of the Messerschmitt Me 262 A-2a Sturmvogel Stormbird!

The Messerschmitt Me 262 A-2a "Sturmvogel" (Stormbird) was a fighter-bomber variant of the world's first operational jet fighter, forced into production by Adolf Hitler's 1943 insistence that the revolutionary aircraft serve as a bomber rather than a pure interceptor. First flying in June 1944, this variant was equipped to carry bombs, resulting in the removal of two of the four 30mm cannons found on the A-la fighter version.

While designed as a high-speed interceptor (the A-1a Schwalbe), the A-2a variant was specialized for ground attack to combat expected Allied invasions. The A-2a suffered from the same issues as the interceptor, including unreliable Junkers Jumo 004 engines, lack of fuel, and vulnerability to Allied fighters during take-off and landing. Despite its speed superiority, the A-2a was not produced in sufficient numbers to change the course of the war.
Many were destroyed on the ground, and only a small fraction of the 1,400+ total Me 262s produced saw combat. By 1945, many A-2as were used in specialized units to attack Allied bomber formations, but they were largely ineffective due to operational, fuel, and pilot training shortages.
