The video shows the trials of the VT-1-1, a turretless tank with 2 x 105 mm guns, firing on the move at the Putlos training ground in 1976. The casemate (turretless) tank, designed for combat while moving, was introduced in Germany in the mid-1970s as a twin-gun casemate tank (the Soviet term for a "turretless tank"). For practical firing tests in the "target pass" mode, two prototypes were built in the mid-1970s. The first prototype, VT 1-1, was armed with two 105 mm guns, while the second, VT 1-2, was equipped with two 120 mm smoothbore guns. Additionally, the VT 1-2 featured a functioning autoloader behind one of the guns, with a firing rate of 10 rounds per minute. The vehicles were developed as part of the KPz 3 or Leopard 3 project. In both prototypes, the main guns were semi-fixed (with aiming and stabilization only in elevation). The chassis solutions were derived from the KPz 70 (MBT 70) program, with the running gear shortened by one road wheel (five road wheels per side). The vehicles weighed 36.8 and 43.5 tons, respectively, with a chassis rotation speed of 60 degrees per second. To achieve high maneuverability on rough terrain, 12-cylinder diesel engines from the MB 873 series with enhanced power were used, equipped with four turbochargers: 2000 hp for VT 1-1 and 2200 hp for VT 1-2. This provided an impressive power-to-weight ratio of 54 and 50 hp/ton, respectively, with acceleration to 55 km/h in 11 seconds, though only in a temporary "turbo" mode, as the standard power was 1600 hp. The accuracy of firing with two guns was unmatched by single-gun tanks, as confirmed by the tests. However, due to the novel combat approach, this revolutionary tank concept was rejected by the customer after trials in favor of the conventionally designed Leopard 2. In essence, although the project was developed as the Leopard 3, a tank for the future, it was, in reality, a parallel project and a potential competitor to the Leopard 2. Achieving the firepower, protection, and mobility of the Leopard 3 within reasonable weight limits was impossible with a conventional layout. At the same time, a significant tactical drawback of the casemate concept (including twin-gun casemate vehicles) is the linkage between the direction of fire and the direction of movement, which in many cases could complicate unit and formation control (according to German experts in the 1970s). Moreover, the VT 1-1 and VT 1-2 can hardly be considered balanced vehicles—they could have been simpler. The vehicles' mobility was exaggerated, with the main engine, transmission, auxiliary engine, batteries, and other systems occupying two-thirds of the vehicle's length. Pros and Cons of VT 1-1 and VT 1-2: Considering the key challenges, the twin-gun casemate concept can be evaluated as follows: Pros: Compact design due to a small internal volume. Two guns provide high firepower and hit probability. Cons: The weight advantage of the casemate design is largely offset by the integration of a second gun. Fire control alone results in high complexity, leading to increased maintenance costs and overall expenses. In 1975/76, five Gefechtsfeldversuchträger (GVT, combat test platforms) were developed and built for further mobility and concept trials. These were smaller than the VT 1-1 and VT 1-2, weighing 30 tons. The GVT 01-05 were equipped only with mock-up guns and laser firing simulators (TALLISSI) and telemetry systems, built using chassis components from the Leopard 1. The GVTs were used at the IABG facility in Lichtenau and the tank training school in Munster to test the twin-gun turretless tank concept in realistic exercise conditions, which is why five vehicles were built. However, the Leopard 2 was already in production, and tank crews showed little enthusiasm for this unconventional vehicle requiring a new approach.

French beauty 1939 Delahaye Type 165 Cabriolet Coachwork by Figoni & Falaschi - Delahaye only built six 12-cylinder Type 165 models in the late 1930s, as production variants of the successful Type 145 competition car. This stunning Figoni et Falaschi-bodied cabriolet was built to represent France at the 1939 New York World’s Fair, an exposition promoted with the slogan “Dawn of a New Day”. While the engine was not completed in time for its display, the modernity and sublime beauty of this car’s flowing styling drew throngs of admirers from the press and public alike. Emile Delahaye was born in Tours, France in 1843. He studied engineering in Angers, France. In 1869 he began work with his engineering degree in applied arts and crafts. Emile Delahaye began business in Tours, France in the middle of 19th Century for the purpose of constructing engines for the ceramic industry. The company branched out and began constructing mechanical appliances such as pumps and engines. In 1888, Delahaye designed an internal combustion engine for the shipping industry. It was not until 1896 that Automobile production began for Delahaye. His first automobiles produced were powered by belt-driven single and twin cylinder engines. Emile used motor racing to promote his vehicles. In 1896, Emile Delahaye entered the Paris-Marseilles race. Not only did he enter a vehicle his company had created, but he entered as the driver. The results were astounding, which truly speaks highly of the caliber and quality of the automobile. The demand for the vehicles began pouring-in and a second factory was opened. After the racing success of its Type 145, Delahaye created the production version, the 12-cylinder Type 165. Two Type 165s were built, and the first was shown in October 1939 at the Paris Auto Salon, the last salon before the war. The second 165 – this cabriolet, with body by Figoni and Falaschi, was so emblematic of 1930s French design that it represented the nation at the 1939 New York World’s Fair. Shipped without an engine because it could not be built in time for the show, an engine sheel, without internals was used instead. The engine-less body was impounded by US Customs when Europe became embroiled in WWII. With Europe engulfed by war by the World’s Fair’s close in 1940, the U.S. Custom’s impounded the Delahaye in New York for the duration of the conflicts. In 1946 Beverly Hills car dealer Roger Barlow purchased the car at public auction, and later that year the Type 165 was fitted with a tuned Cadillac engine. Following his death, it was abandoned by his widow in the 1970s and sold to a tow-truck driver for $1200. After three decades of trading hands at a public auction and receiving a Cadillac engine, it eventually wound up at a used car lot in Honolulu until it was bought by a US military serviceman. It took four years of negotiation, but Peter Mullin and Jim Hull eventually purchased the car in 1985 and spearheaded its restoration. The original engine sheel was tracked back to Count Hubertus von Doenhoff and bought. New engine internals were created from original drawings to finally give the 165 the fully-working engine it was intended to have. This car is now owned by Peter and Merle Mullin and the Peter Mullin Automotive Museum Foundation, where is its displayed in Oxnard, California. © Cars & Motorbikes Stars of the Golden Era #archaeohistories

Reno Omokri is trending because the influencer said real time e-transmission can’t work because Peter Obi’s bank has network problems, and US doesn’t do e-transmission of results. Reno asked viewers to factcheck him. — Apparently all his claims are FALSE. He claims Obi’s bank in 2025 was unable to deliver real time transfers, no access to apps or USSD, recoding thousands of complaint affecting 10million users, yet Obi wants INEC to transmit result to 100M people. Actually, Obi doesn’t own a bank. He once worked with Fidelity bank where he was on its board, he also served as board member of Guardian Express Mortgage Bank Ltd, and Future Views Securities Ltd. Fidelity bank has 500,000 shareholders and none is a majority holder. 1. 2. Also, in 2025 Fidelity Bank recorded one of the lowest customer complaints. According to a report by MonieCentral; GT bank, Zenith, Access, UBA and First Bank, had the highest failed transaction volume. While Wema, Stanbic and Fidelity were low. [ Reno Also claimed USA doesn’t do real time electronic transmission of results. Actually, technically they do. The voting machine collects all votes, aggregates and uploads in batches. Not vote-by-vote transmission, but after counting. The same option Nigerians as asking to be made compulsory. Reno only made a smart submission, but false in context regardless. India, USA, Brazil, Russia don’t use vote-by-vote transmission, not because of tech limitations but, for secrecy, live security, and to delay announcements. In a sense, this is the standard, and the closest to real-time transmission. He concluded that Obi wants real time electronic transmission so that they can hack the IREV, like 2023 when it was hacked 12million times. This is also false. During the PEPT, an Amazon staff testified, confirming the IREV server was not attacked nor suffered any damages. While INEC insisted it was hacked and suffered glitches. [ Nigerians are saying, Reno is only doing his job after securing an Ambassadorial appointment. While patriotic Nigerians agreed with him, reiterating his point and accusing Obi and normal Nigerians of idiocy. Over the weekend, senate President Akpabio, labelled Nigerians demanding e-transmission, unpatriotic. •• Seeing the “glitches” with IREV, data techies built Citizen Monitors 🗳️.

The Incredible 1936 Bugatti Type 57S Atalante - Ettore Bugatti once said, “Nothing is too beautiful, nothing is too expensive.” This pre-war ride could well be proof of that. The Type 57S Bugatti Atalante is regarded by many as the ultimate example of the art of of Bugatti embodied in its engineering, performance and aesthetics. It is a profound work of automotive art coming from the 1930’s, in which period some of the most beautiful automobiles ever made were created. The rare Bugatti Type 57S Atalante Coupé in question is one of the most desirable cars in the French marque’s century-long history. Designed by the aforementioned founder’s son, Jean Bugatti, the Type 57 included S and SC variants (Surbaissé for “lowered” and Compresseur for “supercharger”) that reached very limited production in the 1930s. Named after Greek heroine Atalanta, the Type 57S and 57SC Atalante featured two-door coupe bodywork, a low-slung chassis and an elegant Art Deco aesthetic. They were at the bleeding edge in terms of tech, too, with a 3.3-liter inline-eight engine that could produce 160 hp for a top speed of 120 mph. (Most cars at that time struggled to hit 50 mph.) Indeed, the Type 57 set numerous world records and won the 24 Hours of Le Mans in 1937 and 1939. This fine example is believed to be one of only 17 Atalante Coupés to leave the factory. Dating back to 1936, the 86-year-old four-wheeler features a striking two-tone paint scheme, with a glossy black base and a bright-red French curve on each side. It also has stunning riveting throughout its bodywork. 🎥© Cars & Motorbikes Stars of the Golden Era #archaeohistories

A Breakthrough in Robotics: Spherical Gears Enter Mass Production Spherical gears, the kind of joint that would allow a robot to move like a human shoulder, have been notoriously difficult to manufacture with high precision. That's changing, thanks to a new design and a path to mass production that could have a huge impact on robotics. The breakthrough comes from a new design called the ABENICS spherical gear, developed by researchers at Yamagata University. This innovative mechanism enables a joint to move in three degrees of freedom without the slippage issues of earlier designs. It achieves this by using a "cross-spherical gear" that meshes with one or more "monopole gears." Mass production is now on the horizon. Although the initial manufacturing of the gears was inefficient, Nissei Corporation improved the process and established the necessary technology. The companies Kanematsu and Nissei have now entered the marketing phase, with production expected to begin in 2027. The impact of this technology is significant. Mass-produced spherical gears are expected to enable highly versatile and efficient robotic limbs. ► Humanoid and Mobile Robots: The design allows for compact, high-torque ball joints ideal for creating versatile and efficient robotic limbs. ► Aerospace: Potential applications include deployment mechanisms for satellite solar panels. ► Other Industries: The technology is also being explored for its potential to enhance productivity in healthcare, nursing care, and restaurants.
