The Lublin R-XIII was the Polish army cooperation plane, designed in the early-1930s in the Plage i Laśkiewicz factory in Lublin. Since 1927, they started working on their own prototypes. Those were designed by J. Rudlicki and his team of more than a dozen people including engineers Marian Bartolewski, Jerzy Dąbrowski, Antoni Uszacki, Janusz Lange, Jerzy Teisseyre, Witold Grabowski, Jaworski and others. The factory’s first own product was a reconnaissance bomber Lublin R-VIII built in 1928. Its airliner variant, the R-IX, was constructed in a short while. In 1930, they produced a pilot series of 5 Lublin R-VIIIs, 3 of which were converted to seaplanes in 1932. At the beginning of 1929, they performed a test flight of a liaison aircraft prototype designated R-X; a pilot series composed of 5 examples was built in 1931. Prototypes of the Lublin R-IX airliner (1929) and Lublin R-XI airliner (1930) as well as its improved variant, the R-XVI, failed to meet the requirements of LOT Polish Airlines so the production was not started. However, 5 examples of an air ambulance variant R-XVI were built in 1933-1934. In 1931, they created the R-XII sport aircraft that was not put to use.

Junkers Ju 88 was an extremely versatile and universal bomber. Among its many variants, there were also night versions. Initially, all Ju 88 night fighter versions were based on Ju 88 A frames, in which various specialized equipment was assembled. The situation changed after the introduction of the Ju 88 G, which from the very beginning was designed as a night fighter. The fuselage of the aircraft was deprived of the lower gondola under the nose, which reduced the weight of the aircraft and improved its aerodynamics. Another visual change was the use of a square-shaped vertical stabilizer and a rudder, which was taken from Ju 188.

Grumman F6F Hellcat was one of the best fighter aircraft of the World War Two era and the most effective fighter of the US Navy. There is no doubt that Hellcats won complete air superiority for the Americans over the vast areas of the Pacific, largely contributing to the victory over Japan.

Hitler’s drive to modernize his armed forces gained a new momentum with the arrival on stage of Col. Heinz Guderian – the future spiritus movens of German armored warfare doctrine. Behind the scenes German design teams were busy working on prototypes of vehicles that would soon become the tools of the future war – light Pz. Kpfw. I and II, heavy (in keeping with contemporary classification) Pz.Kpfw. IV and medium Pz.Kpfw. III armed with a 37 mm gun. In the early stages of fighting in France it became clear that the vehicle didn’t carry enough punch and in later marks of the tank the 37 mm main gun was superseded by a 50 mm weapon. The ultimate version of the Pz.Kpfw. III was armed with a short barrel 75 mm gun, the largest that the tank’s turret could accommodate.

The Fiat CR 42 designed by Ing. Celestino Rosatelli, has the undoubted characteristic of being the last single-seat fighter biplane to be manufactured during the Second World War. It represents the final evolution of the aircrafts serie since Fiat CR 30 – 32 – 33 – 40 - 41, made during the 1935-1938 years in Turin. The prototype flew the first time on 23 May 1938 and about 1800 Fiat CR 42 were produced, divided into 15 construction SERIE. There were no productive variants but only small changes along the SERIE due to various operational uses. Despite he was technically overtaken and outclassed by the opposing aircrafts, he honored his duties thanks to the skill and sacrifices of the Regia Aeronautica pilots who used it in almost all fronts war. He was also successfully exported and used in Belgium (Aeronautique Militaire Belge), Hungary (Magyar Kiraly Hoved Légiéro), Germany (Luftwaffe) and Sweden (Flygvapnet). Surviving aircraft were deployed in the post-war era by the Scuola Caccia Aeronautica Militare Italiana Lecce-Galatina airfield and for secondary services in Milano-Linate airfield during the 1950s, both single-seater and two-seater version.

Fairey Swordfish was a British biplane torpedo-bomber and reconnaissance aircraft designed to operate from aircraft carriers or as a reconnaissance seaplane operating from catapult launchers. The prototype was built in 1933 at the Fairey Aviation Co. Ltd. The aircraft had its first flight in 1933, too. It had an open cabin for a three-man crew and a fixed landing gear. It was powered by a Bristol Pegasus II M (640 hp) star engine. In 1934, Fairey Aviation released a second prototype that was equipped with a 690 hp Bristol Pegasus III M3 engine. The new type could also use floats. Series production began in 1935. Fairey Swordfish Mk. I was produced in both: bomber-torpedo-reconnaissance version with a wheeled landing gear and as a floatplane. The machine had a classic tail with a horizontal stabilizer. It also had folding wings. Truss structure fuselage was used, with front covered with metal sheets. In the middle there were three uncovered tandem crew cabins. Undercarriage had a tail wheel and arresting hook under the fuselage. The aircraft was equipped with a inflatable dinghy.

Gloster Gladiator is a British fighter constructed at the Gloster Aircraft Company. The prototype was created in 1934. It was powered by a 645 HP Bristol Mercury VIS engine. Gloster Gladiator Mk I had a 8382 mm long fuselage, which consisted of four numbered sections. The first of these included the engine bed. The second front fuselage, the third – the rear fuselage, and the fourth – tail. The arrangement of instrumentation and equipment inside the truss was marked with letters or numbered from one to eight fuselage partitions corresponding to the distances between the frames. Clearly straight main panels with a span of 9845 mm were built around two Hawker steel girders. The upper and lower supports of the girders were made of rolled octagonal elements, and the wavy lining provided strong points for attaching four aerodynamically profiled transverse struts. Such wing structure was finished with light alloy ribs, stringers and steel and duralumin spreader bars.

The birth of the Ninth Squadron (Novena Escuadrilla) of the Spanish Navy Fleet Air Arm (Flotilla de Aeronaves in short FLOAN) took place in 1987 with the receipt of the first three AV-8B aircraft from McDonnell Douglas factory in St. Louis on October 6 of that year. Deliveries continued for a total of 12 AV-8B Harrier IIs (numbered 01- 901 to 01-912) commonly known as “Day Attack” to differentiate them from later models Night Attack and AV-8B+ or “Radar” Aircraft. On January 29, 1996 the first AV-8B Plus 01-914 joined the squadron. Then continued deliveries up to 01-921, which makes a total of eight AV-8B+ that greatly enhanced the operational capabilities of the squadron. On 1 October 2000 the unit received TAV-8B 01-922, which is the only two-seater with the squadron and together with the simulator allows it to be totally autonomous in the adaptation to training new pilots just graduated from the U.S Naval Aviator pipeline. On July 30, 2003 were received from the now Boeing factory in Saint Louis the first two AV-8B to be remanufactured as AV-8B+ numbered 01-923 and 01-924. On 21 November the same year the last three planes in the remanufacturing programme, 01-925, 01-926 and 01-927 were ferried to Rota Naval Sation flown by Novena Escuadrilla pilots.

The PzKpfw III (Panzerkampfwagen III) is a German medium tank designed by Daimler-Benz AG. The first tests of the vehicle took place in 1936. The construction of the PzKpfw III consisted of four main modules: the turret, the front of the hull, the rear of the hull with the engine compartment cover and the lower hull. The first version of PzKpfw III – Ausf. A – was produced in May 1937. Soon after, the Ausf. B and C versions also entered production. Ausf. D version was introduced in January 1938. Early PzKpfw III models were prototype vehicles and were not suitable for mass production on a large scale. They were powered by Maybach HL 108 TR petrol engines with 250 HP. They were armed with 37mm guns and three MG-34 machine guns (two in the turret and one in the hull).

This early production T-34/76 with F-34 gun was repainted Dunkelgrau RAL 7021 and used by Waffen-SS. An additional storage box was fitted to the left side of the hull. T-34/76 with L-11 gun captured and used by Wehrmacht. It remained in its original camouflage scheme of overall 4BO dark green.A STZ-built T-34/76 model 1941 with F-34 gun coded 4 of 21st Independent Tank Brigade, autumn 1941.

Despite the favored acquisitions abroad by the VVKJ conservatives, in the early 1932 an idea to develop a modern combat airplane was initiated by two young Serbian engineers, Ljubomir D. Ilić and Kosta I. Sivčev, who were at the time employed at the Air Force Command Technical Department. They worked in secret after hours at Ilić’s apartment and designed the first entirely Yugoslav made fighter airplane, the IK-L1, which first took off on 22 April 1935. The second prototype, IK-02, construction began ten months later and the airplane took off for the first time on 24 August 1936. The first 12 series airplanes construction followed in 1937 with the last airplane entering service in February 1939. At the time of the German attack, on 6 April 1941, VVKJ could rely on eight IK-2s, which served with distinction during the short and bloody April war.

The battleship "Nagato" was the first dreadnought equipped with a main artillery with a caliber exceeding 400 mm. It was armed with eight 406 mm (16 in) guns. The keel of "Nagato" was laid in 1917 in the naval shipyard in Kure. The ship was launched in 1919 and incorporated into service on November 15, 1920. The sister unit was “Mutsu”. Before the war, "Nagato" underwent many modifications and repairs increasing combat value of the ship. With the outbreak of World War II, "Nagato" became the flagship of Admiral Isoroku Yamamoto. The attack on Pearl Harbor was ordered from battleship’s deck.

The "Smelyi" type destroyer, Project 30 bis (Skoryi class, according to NATO classification), was the first destroyer designed and built after World War two with new shipbuilding technologies available in the USSR. World War Two demonstrated that all early-built Soviet destroyers had serious flaws. Poor seaworthiness, hull fragility, lack of displacement reserves for modernization. The technical design and working drawings of the new EM were developed under the leadership of the main designer A.L. Fisher. On 28 January 1947, by order of the Council of Ministers of the USSR N3 149-75 "On the construction of destroyers of the 30K and 30 bis Projects", the technical design developed in TsKB-53 was approved. The construction of ships of this series was to take place at four shipyards: No. 190 in Leningrad (now St. Petersburg), No. 200 in Mikolayov, No. 199 in Komsomolsk-on-Amur and No. 402 in Molotov (now the town of Severodvinsk).

M3 General Lee – an American medium tank from World War II era, also used by the British army. In the US, known as Lee, in the United Kingdom as Grant. M3 tank was created as a result of the need to replace the obsolete M2 tank, which did not match the WWII battlefield. The serial production began in August 1941. The M3 tank had many components from the M2 light tank, including chassis, Wright R975 EC2 star engine and the shape of the combat compartment. M3 was meant to be a transitional solution due to the lack of turrets for a 75 mm cannon (M2 type cannon), which was finally mounted in the sponson on the right front of the hull. Second anti-tank gun – 37 mm caliber – was mounted in the turret and intended to fight enemy vehicles. The original M3 was equipped with a riveted hull and a turret in which M6 cannons were mounted (cal. 37 mm). In the M3A1 version the riveted turret construction, dangerous for the crew, was replaced with a cast version. The new turret was easier to assemble, which accelerated the production process. It also reduced the weight of the vehicle. Both guns were equipped with gyroscopic stabilizers. Additional armament included two or three Browning M1919 machine guns, caliber 0.30 inches. In American M3, two Brownings were mounted in a small rotating dome at the top of the turret. In the British version there was a entrance hatch for the crew. The crew of the tank consisted of six soldiers (initially seven). A total of 6258 M3 tanks were produced in all versions. They served in the British, Australian, American and Soviet armies.

Sd.Kfz. 173 Jagdpanther is a German tank destroyer developed by Krupp and Daimler-Benz. The order was placed in August 1943 and the vehicle entered service in the first months of 1944. It was armed with a very effective anti-tank tank gun. PaK 43 cal. 88 mm. The destroyer’s combat compartment was armoured with 40 to 100 mm thick (front plate) armour plates. From January 1944, 415 pieces were produced (at the MIAG, MNH and MBA factories). The vehicle was based on the chassis of the Panther Ausf. G, but it didn’t have as many technical problems as the mentioned tank. Due to the favourable power-to-weight ratio, Jagdpanther had good performance and maneuverability. Together with a powerful cannon, which was able to destroy any allied armoured vehicle that time, it made it an extremely effective and dangerous destroyer. Vehicles were used by independent tank destroyer battalions. Jagdpanthers debuted in Normandy in 1944 (within 555th and 654th Panzerjagerabteilung), achieving great successes. Also during the offensive in the Ardennes, the Allies took a toll on them. They appeared on the Eastern Front in the autumn of 1944, effectively fighting all Soviet armoured guns and heavy tanks, including IS-2.The vehicle was produced in two main variants. The early version – designated as G1 – had a smaller yoke that was welded to the hull, a modified engine compartment from the Panther Ausf. A and two driver’s visors. In the later version – G2 – the Panther Ausf. G engine compartment was used, one driver’s visor and a larger yoke which was bolted to the front plate with screws. There were also many hybrid variants combining the features of both versions. Until September 1944, Jagdpanthers were covered with Zimmerit in the form of characteristic squares, and not the more popular “snakes”. Jagdpanthers proved to be the most effective German tank destroyers, but they appeared too late and in too few numbers to significantly influence the course of the war.
